16x16 LED Matrix RP2040 MCU firmware

Current Version: n/a early development

This is firmware for an RP2040 to drive a 16x16xRGB LED matrix of my own design.

It does NOT use WS2812 LEDs. Details will be available soon.

Implemented Features

• 100 FPS 16x16 LED Matrix RGB control via RP2040 PIO
• Matrix patterns:
  • test_row_by_row_y
    • Test pattern that lights up all pixels in a column and scrolls through all columns
  • test_row_by_row_x
    • Test pattern that lights up all pixels in a row and scrolls through all rows
  • test_scan_x_y
    • Test pattern that scans throw all pixels in a row for each column, lighting one pixel at a time.
  • random_per_pixel
    • All pixels random colors
  • random_corner_breath
    • Randomly chooses a single color, then uses a "breath" dimming effect to "grow" out of a corner and then recede. Color changes after screen dims.
• RP2040 -> ESP32 uart0 bridge via RP2040 USB for flashing
• Automatic ESPtool flash detection and ESP32 bootloader mode (via ESP_SYNC command on USB UART)
