Description

This repogitory contains the sample programs for Nucleo 64 and 144

The samples programs demonstrate following functionality :

• GPIO output
• Interrupt and Task synchronization
• Task
• I2C master
• Printf() functionality

Once started, the program prints out a message to the serial terminal and blinks the LED on the Nucleo board. The serial terminal specification is :

• 115200baud
• 8bit
• None parity
• 1 stop bit

When a user push a user button (blue button) on the Nucleo board, it raises an EXTI interrupt, and this interrupt releases a task to search for I2C.

The demonstration on the Nucleo 32 is just a blinking LED.

What's new

Adapted to Murasaki v4.0.0.

Test environment

• Ubuntu 22.04 LTS
• STM32 CubeIDE (Tested with v 1.12.0)

Supported target

• Nucleo
  • Nucleo H743ZI (Cortex-M7)
  • Nucleo F746ZG (Cortex-M7)
  • Nucleo F722ZE (Cortex-M7)
  • Nucleo H503RB (Cortex-M33)
  • Nucleo F091RC (Cortex-M0)
  • Nucleo F446RE (Cortex-M4)
  • Nucleo G070RB (Cortex-M0+)
  • Nucleo G431RB (Cortex-M4)
  • Nucleo L152RE (Cortex-M3)
  • Nucleo L412RB-P (Cortex-M4)

Known issue : At the point of the Jul/07/2023, following target doesn't work correctly.

• Nucleo L152RE : The bug in the CubeIDE 1.12 prevents to build the EXTI class. See the report .
