Hi Terry,

we see no issue with this.

if you are looking for more control, you can utilize the MPSSE engine using the D2XX drivers directly. This will mean you will not have to rely on LibMPSSE.

To use I2C/SPI as a master (no slave functionality), 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. Source code is also provided.
Note there is a known issue with this library with I2C. See LibMPSSE Beta 1.0.2 which shows the source code change to allow you to rebuild.
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).

Best Regards
