John Boyd created simple controller for RGB LED panels with the Texas Instruments MSP432 ARM microcontroller:
MSP432 RGB LED Panel Controller
I have managed to get it working without issue at 60 FPS [..] I think I could push to above 100 FPS.
The challenging part of this project was designing the firmware in a way to leverage all of the MSP432 peripherals to reduce the computational requirements for the CPU.
The hardware design files and firmware source code are hosted on GitHub:
