点阵屏兼容性 - breakstring/esp32-hub75-devkit GitHub Wiki

本开发板可以适配这个驱动库，理论上该库支持的点阵屏我这块板子都能够支持。按照它的README中所提及，支持如下：

  • 64x32 (width x height) pixel 1/16 Scan LED Matrix 'Indoor' Panel, such as this typical RGB panel available for purchase.
  • 64x64 pixel 1/32 Scan LED Matrix 'Indoor' Panel.
  • 32x16 pixel 1/4 Scan LED Matrix 'Indoor' Panel using an ingenious workaround as demonstrated in the 32x16_1_4_ScanPanel example.

具体来说，支持的驱动芯片有：

  • ICND2012
  • RUC7258
  • FM6126A AKA ICN2038S, FM6124 (Refer to PatternPlasma example on how to use.)

不支持的板子：

  • 1/8 Scan LED Matrix Panels are not supported.
  • RUL5358 / SHIFTREG_ABC_BIN_DE based panels are not supported.
  • 其他上面没有列出的.

按照我测试的结果，先后在淘宝上买过若干块64X32或者64X64的，都能够正常工作。但是128X64的不行。如果您对显示的点阵数量有更多要求，建议采用64X64或者64X32的点阵简单串联，或者组成虚拟屏幕来实现。
