Hi Peter, the best way to do this is for you to: 1) fork the github project 2) make your changes locally 3) commit your changes to Github 4) send a Github pull request Regards, Stephen

Fantastic! Have you got it talking to a device yet?

Just checked my setup. Directory C:\Users\me\d2xx contains 4 files - ftd2xx.h, LibFT4222.h, ftd2xx.lib and LibFT4222.lib. The .dll file mentioned in step 4 is not in that directory. That step should be ignored. Directory C:\Windows\System32 contains - ftd2xx.dll, FTDIInterface.dll and LibFT4222-64.dll. Directory C:\Windows\SysWOW64 contains - ftd2xx.dll only. I don't remember touching SysWOW64, suspect that Windows PnP driver installation put the ft2dxx.dll's into both System32 and SysWOW64. Be warned,...

I've uploaded the .dll and .jar files that produced that output to: https://sourceforge.net/projects/yad2xx/files/REL-2.1-SNAPSHOT/

Hi Peter, I hate to say it but it works for me: C:\Users\usr\projects\yad2xx>java -cp yad2xxJava\target\yad2xxJava-2.1-SNAPSHOT-jar-with-dependencies.jar net.sf.yad2xx.ft4222.samples.I2cMasterSample Dev 0: Flags=2 (isOpen: false isHighSpeed: true) Type=a (FT_DEVICE_4222H_0) ID=403601c locID=121 SerialNumber=A Description=FT4222 A ftHandle=0 Init FT4222 as I2C master I2C master write data to the slave(0x20)... bytes written: 2 I2C master read data from the slave(0x20)... slave data: 0xa5, 0xc3, UnInitialize...

Hi Peter, the UMFT4222EV module turned up yesterday. I've got the example code working correctly on macOS with a PCF8575 I2C slave device: yad2xx$ java -cp yad2xxJava/target/yad2xxJava-2.1-SNAPSHOT-jar-with-dependencies.jar net.sf.yad2xx.ft4222.samples.I2cMasterSample Dev 0: Flags=2 (isOpen: false isHighSpeed: true) Type=a (FT_DEVICE_4222H_0) ID=403601c locID=14111 SerialNumber= Description=FT4222 A ftHandle=0 Init FT4222 as I2C master I2C master write data to the slave(0x20)... bytes written: 2...

I spent some time working on this over the weekend on macOS. I encountered similar problems with 3rd party libraries. It looks like LibFT4222 has been written in C++ and this means that the driver is not standalone, it requires additional libraries to function. On macOS this means the boost libraries need to be present. FTDI ships the correct versions as part of the LibFt4222 download but because they don't provide any install instructions it's easy to overlook. I hadn't set my environment up correctly,...

The associated makefile. Use command "mingw32-make" to build.
