I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
Description
With both USB and RS232 serial interfaces this is a truly universalI2C/SMBUS/SPI/1-Wire interface, for the widest possible range of computinghardware, with the simplest and most portable software format.
I2C2PC is not an I2C slave or an I2C monitor. It is a master on the I2C/SPI bus only.
Building an I2C based application needs nothing more than your I2C chip, everythingelse is included.
There is an internal 5V and 3.3V power supply to run the interface and your targethardware. Simple systems will run from the USB bus power.
Unlike some competing products, it can sustain high baud rates, and has multiple I2CBussesCompared to cruder solutions, it doesn't rely on bit-bashing PC software, ill definedI/O characterisics, or processor and OS dependent timing. Unlike single chip USBsolutions it can guarantee timing of I2C transactions
Power-On-Reset actions can be set in EEProm so that systems are properly initialisedwhen the PC is not present.Watchdog actions can be programmed to automatically respond to PC failure.
Galvanic isolation can be installed where the I2C busses need to be isolated from thecomputer for noise, ground loop, or safety considerations.
An optional 3rd TTL interface is available for Fibre Optic, Bluetooth, RS422 andsimilar interfaces, or development for your own BL233 product.

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
2 CommandsRead the BL233 B PDF Datasheet for a full description of commands and operation.
There are application notes for BL233 and i2c2pc that clarify specific applications, and other information in the PDF Library
3 Software InterfaceThe I2C-2-PC appears as a serial port device when either the USB or RS232 are used.(Linux, Windows, Mac).No special API's or DLL's are required to access it. Almost any programming language can be used including Labview. Our customers are using it with VB C, C++ Labview Matlab Delphi Java Python Perl PDA's Batch files
4 Installing and Testing Your New AdaptorThe I2C2PC is normally shipped set to 57,600 bd N81, RTS/CTS handshake.
If you have Galvanic Isolation fitted, see sec 11 below.
The jumpers are set 5V, and IRQ on the I2C buses.
Download, Install Realterm from: http://www.i2cchip.com/realterm Documentation is at http://realterm.sourceforge.net/ View the Videos Starter Kit Introduction Video, http://www.i2cchip.com/videos
Use the “Realterm I2C USB” shortcut to start up Realtern. This will automatically configure the port settings to hardware handshake RTS/CTS.
Ensure the Port Select jumper is in AUTO position (ie not fitted). The port will default to RS232 when the USB is not connected.
If you are going to use the USB, install the FTDI driver software for Windows. http://www.ftdichip.com/Drivers/VCP.htm

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
Connect USB cable. Select port \VCP0 or Connect a DB9 serial extender (m-f) cable (not a cross over cable) to the RS232
(and select comport) . Apply 9V Centre positive 2.1mm power supply. When you apply power you should see a default startup message like “HI I2C v118”. Note you probably won't see this when using USB power, as the message is normally sent before the USB bus has enumerated.
Type “?”. The I2C2PC should reply with 2 hex bytes of status eg “18” All units are fully tested in our ATE system. It is unlikely it is not working out of
the box.
5 JumpersThe back of the PCB has silkscreen of the jumpers with their functions labelled.

6.1 Aux Interface CN9
CN9 is a third serial interface that can be manually selected instead of RS232 and USB. It is selected by installing link J1, and the setting J2 to USB.
*** WARNING: While it uses a 6 pin micromatch it is completely incompatible with the I2C bus. Do not plug into the wrong socket ***
You can use it to add a 3rd interface, eg Bluetooth or Fibre or RS422 or TTLIt can be directly connected to the logic level2 pins of a UART or microprocessor serial pins. For example you can connect it direct to the serial pins of a Linksys WRT54G Linux router. It is directly compatible with 3V and 5V devices. This is also ideal where you plan to use the BL233 in your own design.
1 Boards before 2011 had J3 fitted at edge of case. After 2011 only J2 is fitted internally.Boards before May 2003 are:Jumper toward DB9: Always USBJumper toward USB connector: Autoselect USB when enumerated, RS232 otherwise.No Jumper: Always RS232
2You cannot connect CN9 directly to RS232. RS232 is inverted and has high voltage levels

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
6.1.1 Regulator for Aux InterfaceIf you need a lower voltage (eg 3.3V) to power the device on CN9, there are 3 pads labeled CN4, adjacent to CN9 which can take a Microchip MCP1700-XX-T0 or Holtek HT73XX regulator in to-92 package.Cut track between Pin1&Pin 3. Fit regulator, Fit C13 next to U3.
6.2 Bluetooth on AuxBLE Adaptors are available from webstore. See I2C2PC_Bluetooth.pdf for more details.Bluetooth Low Energy and Bluetooth modules can be directly connected to CN9. Set the module to 57600bd using its AT command set, and you are ready to go.

7 I2C Bus ConnectorThe I2C Bus connector used is a MICRO-MATCH by AMP. Either 4 or 6 way can be used. 6 Way I2C Connectors and Cables are available from I2CCHIP, as well as from Farnell. I2CCHIP can supply bulk connectors (boxes of 250) if required as well as cables, andsmall quantities of connectors.

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
The reason for the power lines being between the I2C wires is to stop the edges of SDA and SCL coupling together. This follows the Philips pattern set out in section 17.3 of The I2C Bus Specification.– If the length of the bus lines exceeds 10 cm– This arrangement will have similar capactive loading on SDA and SCL. Where
you don't use pins 5 & 6, it can be better to just use 4 wires.

8 CS and Interrupt PinsJumpers J4,5 are provided to select the function of pin 5 of the I2C connector betweenIRQ (input), and CS/1Wire (i/o). This is for BUS# 2, 3 only. Bus#1 is always connected to IRQ.
If you are using the adaptor for SPI, you will need to change the jumper position to CS to make it an output.
Note that the IRQ pin is common to all buses it is connected to. So changing its level at one bus, will affect all of them.
9 Bus Drive and PullupsThe bus is fitted with 1k5 pullup resistors in a SIL resistor pack.
If you want to reduce or increase the current, replace the resistor pack. Werecommend cutting it out with fine side cutters, removing the individual pins throughthe top of the board, and desoldering the holes.
Note that although Bus#3 may be pulled up to 5V, it has a diode clamp that keeps thevoltage down to VDD on that bus.

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
The BL233 can drive much higher currents if required, 15-20mA @5V VCC. Thereis a 47 ohm protection resistor in series with the outputs that will need to be reducedof course. You will need a buffer at the other end of the bus if you do this.
10 Power SupplyExternal power is 9-12V DC, (2.1mm centre positive). An on board 7805 regulator is fitted to provide 5V. An HT7333 regulator provides 3.3V at up to 250mA.
If you have a Galvanic Isolated adaptor, see 11.2 belowIf you want to use low voltage I2C devices (<3.3V) see: Low Voltage Regulator for Bus 3 12.1 below
USB Bus Powered USB Data: ~50mA for I2C devices USB Bus Powered RS232 Data: ~50mA for I2C devices External Power, RS232 External Power USB
10.1 USB Bus PoweredThe USB bus can deliver up to 500mA3. When operating from USB, the supply voltage is normally about 4.7V. The 3.3V regulator will operate correctly from the USB supply.Even if you are using the RS232 port, you can use a USB cable for power. Just fit the RS232 jumper to force the adaptor to ignore the usb port.Note that USB power can be very noisy, and can go as low as 4.4V when other devices are used with unpowered hubs. Using the 3.3V regulator for the I2C may be best for USB powered applications that are noise sensitive.
10.2 I2C Bus Power Selection 5V / 3.3VI2C Bus #1,2 are connected to the BL233B's VDD supply. J6 selects between 5V and 3.3V for the BL233B's VDD.
I2C Bus#3 has a separate VDD jumper J7. Using J7 you can operate I2C Bus#3 from either 5V or 3.3V, while Bus#1,2 are operating from 5V.
3Devices that draw > 100mA from the bus should have switched load, and in theory you should changelinks on the FT232, so the adaptor tells the PC that it is a high current device. See FT232BM datasheet for more detail if this matters to you.

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
If you leave J7 off completely, then you can power Bus#3 from another the I2C cable.Bus#3 has TTL levels and an in-built diode bus clamp, that keeps clamps the voltage on SDA and SCL to the Bus#3 VDD. This means that you can oiperate Bus#3 VDD from 2-5V
The I2C Bus VDD is connected to the interfaces VDD (5V). To isolate an I2C Bus#1 or 2's VDD from the adaptors VDD, remove the associated 0603 link by the connector. (FB10,11)
10.3 Local AND USB PowerBoards manufactured after April 20034 should work happily with both external and USB power.If you do not want the USB bus to try and power your equipment, remove D5 (by USB connector). Normally you would do this when building the I2C-2-PC into a standalone equipment that has its own 5V supply.
If you are making test systems, be aware that a short circuit, high voltages etc, that may accidentally be applied to the VDD of the I2C bus, will be connected through theUSB cable to the power supply of your computer. This can reset your computer or worse. For these applications, the Galvanic Isolated option is available.
11 Galvanic IsolationBefore using a new Galvanic Isolated unit anywhere safety-critical, you should use a multimeter to verify that the input and output side of the adaptor are actually isolated. This is good practice. Note that these units have not been tested by any certifying laboratories, and we do not claim that they comply with any particular standards for isolation. It is your responsibility to ensure they are fit for purpose.
DC-DC Converters are fitted as standard to Galvanic units from mid 2015
Adaptors and Starter Kits can be ordered with Galvanic Isolation. Isolated versionshave:
• Case is marked Isolated• Isolator is fitted to pcb. • DC-DC convertor powers I2C from USB (mid 2015 on)
4With boards manufactured before May 2003:There are some traps to watch when using a local power source, and the USB adaptor. The USB chip will not see a power on reset when the USB Bus is connected, and local power is already applied, and may not enumerate correctly. See FTDI documentation for more reset details.

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
You should use the Galvanic Isolated version if: • I2C side can be inadvertently short-circuited and you are using USB• Faults at the I2C could possibly connect high voltages to any pins of the
adaptor (including the ground pin)• You don't want to ground your I2C bus to the PC chassis• Measurements are sensitive and you need to decouple from the PC's noise, and
ground currents, and earth loops.• This is a valuable and important industrial system that should be designed to
be robust.• You need to run the I2C bus floating or above ground potential
The Analog Devices ADUM1402A5 is used for isolation in V3 adaptors For more information see the datasheet. Creepage distance is ~2.5mm.
11.1 Fitting Isolator Yourself
If you need isolation, either mill, or chisel the bridging tracks from the isolator footprint and fit the IC.If you use RS232, and an isolator you will need to power the RS232 section. Fit CN4,and protection diode D1 (BZX85C5V6 or C6V2)
11.2 Galvanic Isolated Power
DC-DC Converters to power the I2C from the USB power, are fitted as standard to Galvanic units from mid 2015. 1W / 200mA units are fitted. Warning: shorting +5 can destroy the DC-DC convertor. If this may occur limit the usb supply or fit a Polyfuse to limit current to 200mA.The DC-DC convertor has an unregulated output, and so the exact voltage (5V) depends on both the USB supply and the load on the I2C side. To increase the I2C side ~0.3V, bridge the USB power diode shown in blue above.
5The NVE IL716-3 magnetic isolator is used for galvanic isolation on old V2 units

Figure11.3: Normal Figure 11.1: Isolated Top View Figure 11.2: Bottom View
I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
On older units, you have to power the PC side separately from the I2C side. Normally USB power is used for the PC side, and an external 9V supply for the I2C side. To use external supply (for greater current or better noise and regulation) cut LK1.
If you want to use the RS232 interface, you can still use the USB connector to providepower. Just fit the "RS232" jumper to force the interface to use RS232. (with no jumper the interface autoselects USB when the USB is connected to a computer, but not when a USB power-only cable is used)
11.3 USB Power only CableYou can use a USB Power-only cable to power the PC side, when using RS232. This is just a USB cable with only the 2 power wires fitted. Just cut the end off a Usb cable. Normally the power wires are red and blue, and thicker than the data wires.
11.4 External 5V to PC SideIf you are not using USB power, fit 2 pin connector CN4 and protection zener D1 (BZX85C5V6 or BZX85C6V2).The PC side requires 4-5V, 30mA.See the wires in Figure 5 below
11.5 Fitting a DC-DC Convertor
If you want to power one side of the isolation barrier from the other, you can fit a 5V-5V DC-DC convertor module. Part# Manuf. Digikey Future Elx Mouser

Figure 11.4:
I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
Adaptors made after 2011 have pads to fit a standard DIP convertor, next to the DC Jack, marked T1 on the silkscreen. The pads are slightly confusing, as you can fit the DC-DC convertor module either way around. The arrows on the silkscreen show you which way the power flows.
• Fit as T1 powers I2C side from USB side. (Pin 1 on USB side, see Figure 12Isolated Top View above)
• Fit as T1A powers RS232/USB side from DC power jack (I2C side, Pin1 on I2C side)
If you wish to fit another type of convertor, just wire to the pads labeled +/- in the T1 footprint.Links LK1 and LK2 select the input to T1A. Use LK2 if you have a 9V in, 5V out type convertor.
11.6 Defeating IsolationIf you don't need the isolation you can simply remove the DC-DC convertor and join VCC and GND across the DC-DC convertor holes. Beware of forgetting that the isolation is gone! Mark the case Not Isolated!
12 Other Modifications
12.1 Low Voltage Regulator for Bus 3Bus 3 will support low voltages. See i2cad_Using_Low_Voltage_Devices.pdf. You can fit an extra regulator U9, Microchip MCP1700-XX-T0 or Holtek HT73XX if you want voltages other than 3.3 and 5V. This is a TO-92 style regulator for easy fitting.
If you fit optional internal regulator U9, leave J7 off.
When VDD is 5V, Bus 3 can be as low as 2.5V. When VDD is 3.3V, Bus 3 can be as low as 1.8V.
12.2 Daughter Board ConnectorI2C2PC can be used as a daughter/mother board that plugs onto another board, insteadof using cables from the I2C Bus.
A 12 pin SIL 0.1” pitch connector CN10 can be fitted from either top or bottom side of the PCB.
VCC is 5V or 3V3 as selected by J6.VCC3 is the output of the 3V regulator.

Figure 12.1:CN10 Pinout
I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
If the adaptor has USB power or external power, VCC can be used to power the external module. Alternatively you can feed 5V into VCC from CN10.
See the Mechanical drawing at end for details of the position and mounting holes. DXF and Altium PCB files are available.
12.3 USB Leds and Power LedUSB-RX (led1) and USB-TX (led2) leds can be fitted if you want. Use 5V built-in resistor type leds (or use 3mm leds + 330 ohm resistors). These LEDs flash briefly when data is sent or received through the USB bus. They are useful for debugging purposes. Led3 is a power LED. V4 adaptors have plain pads on the top side for these signals. (Earlier adaptors had holes for LEDs)
12.4 USB EEPromUSB info can be set using FTDI utilities. This will let you enumerate the device as something other than a generic usb/serial adaptor, as well as setting special information such as current consumption.Boards manufactured before 2011 use FT232B, and require the 93C46B EEProm to be fitted to the pcb. Post 2011 boards use FT232R and have built in eeprom.
Some customers have reported that Windows XP does not correctly handle multiple adaptors on the same USB, and that this may be fitted, and a unique serial number set.Later (post 2011) FT232R boards have unique serial numbers by default.

Use a Philips PCF8591 4 channel 8 bit A-D chip. Store this macro in the EEProm at location 0. It will run automatically at power on, sending 4 channels of A-D data in hex, followed by LFS90 04 R04 T0A L0200 >00[Start][address 0x90 (8591)][Control register=0x04][Read 4 channels of A-D] [Type LF (linefeed)][delay 512 ms][goto start]Capture the data to file with Realterm.Plot it with Excel, Matlab etc.
13.3 Simple RS232 I/O Port
The I2C-2-PC can be used directly as an 8 bit I/O port with a 1 bit IRQ input. No I2C or SPI chips are needed at all. This is ideal for connecting relays, lights and switches to a PC.O OF[write 0x0F direct to pins]Q[read pins]?[read IRQ input]
13.4 RS232 to LCD Module adaptor
A single PCF8574 can drive a standard LCD module. This circuit is available built up.
13.5 Huge RS232 Parallel Port
To get are large number of cheap and easy output pins with good drive capability, use the SPI output, and 74HC4094 shift registers. Eg a 32 bit output with 4x 4094's. SDA4 is used as STB for the 4094'sG3 Y01020408 OFFFD OFFFC

14 USBUSB requires the Virtual Comport drivers for Windows. For other operating systems see http://www.ftdichip.com/Drivers/VCP.htm
USB introduces latency that may affect your software design. See AN232B-04 Data Throughput, Latency & Handshaking
This latency affects all USB devices. To avoid it you should structure your software to decouple the commands you send from the data coming back. ie you send as many commands as possible to the BL233, then you process the data as it returns. If you send a command, then wait for each response, performance can be very poor.
Just because USB runs at 12Mbps does not mean it really works fast. RS232 may perform better in practice. This is why we provide both interfaces.
The USB configuration in EEProm can be changed so that it enumerates as a special device rather than a virtual comm port. FTDI utilities can be provided to do thisFTDI provides D2XX DLL Drivers are to directly access the USB interface. http://www.ftdichip.com/Drivers/VCP.htmWe recommend using the Virtual Comm Port approach, as you retain the flexibility touse RS232 with no software changes.
14.1.1 Changing Comport NumbersKeep the adaptor on the same port of the computer / hub, to avoid the comport number jumping around.
14.2 Should I use USB or RS232?If you are making test systems or otherwise require reliability and performance, werecommend that you try and use a real serial port, rather than USB. Reliability doesnot depend on drivers, and on other USB devices being connnected and disconnected

from the computer. The Comport number will not move around. Latency is reduced,and more reliable.
15 FAQ
The BL233 datasheet is the place to find answers to all your software questions!
Can I use SMBUS chipsYes. SMBUS chip will usually operate directly. SMBus chips have timeout, so you may not be able to type commands from the keyboard. Use the Realterm SEND tab, Using the “:” command in your programs may be a good idea.
Can I mix 5V and 3V IC's?Yes. Bus# 3 has TTL Levels. You can have bus 1&2 at 5V and bus 3 at 3.3V
Can I use 2.5V or 1.8V I2C.Yes – on Bus 3. See i2cad_Using_Low_Voltage_Devices.pdf
My adaptor doesn't work. I have Galvanic Isolation. (Before mid 2015) You have to power the PC side and the I2C side separately. See Isolation section 11.2
Will your product continue to be available.Yes it is a sucessful product with a growing market. We have seen many competitors come and go. Importantly, our ASCII command approach is futureproof against changes in OS's and programming fashions. You will never me reliant on us updating drivers or DLL's to keep using the system.
USB is really slow?Latency is an issue. See USB section 14
The data is gobbledygook.First use Realterm to test the adaptor. Make sure the baud rate is correct (57600 is default) and that you are using RTS/CTS handshaking. Once you have used Realterm to send commands successfully and found out what the returned data is, you are readyto start writing your software.
Realterm doesn't do XXXXTry the latest development version of Realterm at http://www.i2cchip.com/realterm
Does it work with Labview?

I2C for PCUSB & RS232 TO I2C/SPI ADAPTOR & CONTROLLER
Yes. Labview has good serial support
Does it work with Linux / Solaris / MacYes. No special drivers are required. You will probably find it easier to use the rs232 interface. Does it work with iOS / Android?Get the BluetoothLE adaptor. If your Android device has OTG you may be able to use the FTDI serial.Another options is our WebI2C solution that gives you Wifi/LAN/Web access
How do I interface to a Wireless Router.We now have a product WebI2C, based on an OpenWRT Router, ask for more details.Most routers such as the Linksys RTA54G have a logic level serial port. This can be connected directly to the AUX port. You may need to put 4k7 resistors in series for level shifting.Some routers (eg ASUS) have a USB port, and may have be able to work with the USB-Serial interface.
16 Factory Test ProcedureThis is the factory test procedure:
16.1 Visual InspectionInspect paying close attention to all leaded solder joints.
16.2 DC Supply current and Power supplySet PSU to 0V.Connect to DC socket.Increase supply voltage slowly to 8V, whilst measuring the 5V line across D2, and watching for excessive current (>50mA)Check supply voltage on BL233B is between 4.75 and 5.25VChange jumper J6 to 3V position, check voltage is 3.2-3.4V
16.3 RS232Install RS232 jumperConnect RS232 cable and set terminal program to nominal baud rate (normally 57600)Connect power to adaptorTerminal should display "HI I2CAD V118" or similar. Note that once the EEProm has been changed this may no longer be true.

Type "?". Board will reply with 2 chars eg 18
Remove jumper (auto-select).Type "?" again and check still works
16.4 USB(Note that FTDI USB/serial adaptor drivers may need to be installed first time)Remove RS232. Plug in USB.Type "?" and check response.In case of problems check the USB RX and USB TX LED positions with an oscilloscope. These pulse low when chars are received or sent. Note that you won't see the "HI I2CAD V118" power on message through the USB port as the USB connection is not enumerated yet, when the BL232 starts.
