FT232H and Serial Port
« on: February 22, 2022, 03:05:13 AM »

I am a newbie to all this.

I am using FT232H as a USB to serial [ SCLK, SDI, SDO] converter.

In Win10 Home, I have used FTD2XX_NET and dotnet 6 framework and managed to talk to USB chip as per C#-example 3 on code examples section on the ftdi website.
I can read the Serial number, description from the USB chip.

- this examples does a UART loopback test so set baud rate etc UART related parameters.

I need a sample code which in C# which can set SPI parameters such as clock rate, 16bits/word and the do a block read ot 128 bytes.

Can you point my nose in the right direction.

Thanks in advance

To use I2C/SPI as a master, see AN_135 MPSSE Basics and our existing MPSSE Example projects:
There are two options to use I2C/SPI modes with the MPSSE engine:
a.            Use LibMPSSE libraries. Example code is provided with the download.
b.            Use D2XX drivers direct. Example code is shown at I2C/SPI.
AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes provides the necessary information.
Option b is the best option to use the D2XX drivers direct (no dependency on libMPSSE library).

Unfortunately in option b above, we only have C++, Delphi and VB examples.
There is a C# example for I2C which you could use for reference.

We do have a C# wrapper which you could use to develop your own software:
