ESP32 frame buffer for HUB75 LED display??
I have been working on the driver for a raspberry, but even with a reatime kernel you still see glitches on the display when other things occur on the PI. I have implemented a shared memory reatime driver for the display on a PI/Basically I split out the driver that was supplied by Adafruit's suggestion tuned it up and bit and added some realtime loops which works pretty well as long as the PI does little else. The driver loop pulls about 50% of the CPU on a PI2b, 32% of a PI3b. (single core). So I'm toying with either going the FPGA route or something like a ESP32 board. FPGA looks like a much larger learning curve so i'm leaning toward the ESP32.. Or if you have a suggestion of a better Ardunio like realtime processor with the kick to do this?
Thoughts?
