MPSSELight

Lightweight .net Multi Purpose Synchronous Serial Engine (MPSSE) library for FT2232D, FT232H, FT2232H and FT4232H devices. Works over the default FTDI drivers (D2XX plus its .net wrapper FTD2XX_NET). Unlike libMPSSE-.Net-Wrapper it is not based on libMPSSE.

SPI use example can be found in MPSSELightTest/SpiTest.cs:

using (MpsseDevice mpsse = new FT2232D("A"))
{
    SpiDevice spi = new SpiDevice(mpsse);

    byte[] tData = { 0x0D, 0x01, 0x0F };
    spi.write(tData);
}

SpiLight

SpiLight is a small command line application that transfer data over SPI. It is based on MPSSELight.

           v:verbose               Print details during execution
   

2. get connected FTDI device list

   >SpiLight.exe -l
   Device Index:  0
   Flags:         0
   Type:          FT_DEVICE_2232
   ID:            4036010
   Location ID:   0
   Serial Number: A
   Description:   Dual RS232 A
   Handle:        0
   
   Device Index:  1
   Flags:         0
   Type:          FT_DEVICE_2232
   ID:            4036010
   Location ID:   0
   Serial Number: B
   Description:   Dual RS232 B
   Handle:        0
   

3. Send data over SPI with loopback enabled

   >SpiLight.exe -d A -L -I in.txt -Ss
   MPSSE init success with clock frequency 2000000,0 Hz
   SPI init success
   output:     AB0102ACFF0030
   input:      AB0102ACFF0030
   

4. Working in verbose mode

   >SpiLight.exe -d A -L -I in.txt -Ss -v -D 7
   raw input:  nothing
   raw output: AA
   raw input:  FAAA
   raw output: AB
   raw input:  FAAB
   raw output: 860700
   MPSSE init success with clock frequency 750000,0 Hz
