STMicroelectronics NUCLEO-H745ZI-Q bare-metal examples (without HAL)

All from the following examples running at 400MHz on Cortex-M7. The Cortex-M4 isn't currently used.

ATTENTION:
In the default setup from the board, the solder bridges are in direct SMPS power supply mode. In this mode, the overdrive mode VOS0 (480MHz) isn't supported.

NOTE:
These examples doesn't require STM32CubeIDE. The only tools to build these examples is GCC for ARM (arm-none-eabi) and the GNU binutils.

GPIO example

This is a small example which toggles LD2 (yellow user LED) with the user button B1 (blue button). LD3 (red LED) is used as heartbeat. It uses the Coretx-M7 SysTick timer.

How to build

Simple type make in the gpio directory.

TODO

  • Add a delay function for button bouncing.
