Driving HUB75 RGB Matrices on Raspi 5 with PIO 💡😎
Since the latest release of 'piolib' we can do things like drive NeoPixels on any pin on the Raspberry Pi 5
CircuitPython is the best new way to code microcontrollers. But what if you want to run that same code on a more POWERFUL computer like a Ra
which rocks, and means we can tackle the next, more complex, project: driving HUB75 RGB Matrix displays
Wintertime can be rough in the city. The sky is gray. The weather is unpredictable. So slough off those seasonal blues with some&n
these require even MORE timing freakiness: using 10 pins, and 'manual' PWM means we have to constantly blit out the color dithering. Historically this was done with mmap'd memory to the GPIO controller bitbanging, which required a full core and could jitter depending on load. But now we can use the PIO peripheral! We can drive massive display arrays at high speeds and color depths using just about any pins. The future is looking bright 😎
