Working with STM32
Hardware Connection
Preparation
- RGB-Matrix-P*-64x32 (* indicates the matrix in different pixels).
- STM32F103RB (Not Included)
Hardware Connection Diagram
Software Setting
- The demo is based on the HAL library. Download the demo, find the STM32 demo file directory - enter HUB75.uvprojx under the STM32\STM32F103RBT6\MDK-ARM directory.
- Compile and download. Then connect it to the display, and you can enter the display. (Please make sure the external power supply of 5V 4A is provided; otherwise, it may lead to IO malfunction.)
