FT90x Transferring Data via USB
« on: August 20, 2019, 08:12:37 AM »


I try to make USB to I2C/SPI with ft90x MCU and I want to make a GUI with MS Visual Studio but Bridgetek supports eclipse so I decided to make a main function which will be include all source codes and receive data from GUI for use them then I will save these mcu memory with eclipse. After that I will make a GUI with FTD2XX.NET , this GUI will only receive data from the user(i.e speed mode,clock speed, slave address etc.)  and send these data mcu over USB with FT_Write function but i confused where to write data? I search D2XX Programmer's Guide and says 'Write data to the device' so can you give more detail?

Finally, I design a PCB and itit hasn't arrived yet so all of them is a theory.Is it possible this theory?

Best Regards.

Which USB interface are you using?
If you are using the USB D2XX interfaces on this FT90x then this is possible.

See the D2XX examples here:

AN_360 FT9xx Example Applications

Also see the D2XX Programmer's Guide which provides software examples.

In your application running on the PC, calling FT_Write would write data to the FT90x via USB then you could read that data using D2XX_Read.
See section 2.35 D2XX Feature in AN_365 FT9xx API Programmers Manual.
