I have been reading all the ANs about FTDI libMPSSE and FTD2XX library, and can not find any explicit description of the proper procedure to use a single MPSSE channel for both I2C and SPI, initialisation and deinitialisation. We are using FTDI2232H. Should we use FT_Purge, FT_Close and FT_Open (with FT_CyclePort if there are any errors), or is just a simple FtdiDevice.SetBitMode(0x00, 0x00); enough to reset the MPSSE interface (and libMPSSE library) to enable initialisation of other protocol?
