The STM32H745I Discovery kit is an affordable development board with:
- 480x272 RGB interface LCD with capacitive multi-touch panel
- Arm® Cortex®-M7 480MHz and Arm® Cortex®-M4 240MHz dual-core
- 2 Mbytes Flash Memory
- 1 Mbyes RAM
- 2 x 512-Mbit Quad-SPI NOR Flash Memory
- 128-Mbit SDRAM
- GPU.
The CubeMX drivers are used to initilaize the peripherals.
The project was created with CubeIDE.
- Clone the project:
