C++ driver for Pimoroni LED-Shim

I have the LED-Shim and would like to control it directly from a C++ program in Raspbian OS, instead of Python. Has any one any information about doing this instead. I know how to call Python from c++ code but would like to use the shim as a real-time debugging visual aid. So I need a tight interface to the led string. I also have the Adafruit-IS31FL3731.cpp code as a reference.

Perhaps someone has prior experience with this?

It uses a IS31FL3731 LED matrix driver chip if that helps. You could try doing a search for C code for that chip. You might have some head scratching to do even if you find it but it may be some place to start.
