Has anyone used a MicroDot pHAT from a C program?
I have already got a FourLetter pHAT and I ported the Python code to a C library. I don’t really want to do that again for the MicroDot pHAT.
Not to my knowledge.
If it helps, MicroDot pHAT consists of three IS31FL3730 driver ICs with two matrix displays running on each one, and with slightly weird pixel mapping. It may be possible to find a C driver for the IS31FL3730 as a starting point.
