MicroPython source-level debugging on STM32C071 with only 24 KB RAM

[Dat Tran]

We recently added support for STM32C071 to our free, MIT-licensed MicroPython Debugger for VS Code.

The interesting part is that the STM32C071 has only 24 KB of RAM and 128 KB of Flash, yet you can still use source-level debugging directly from VS Code.

Set a breakpoint in your MicroPython source, press F5, and debug the code running on the actual STM32 MCU.

The debugger supports:

• Breakpoints
• Step Over / Step Into / Step Out
• Variable inspection
• Watch
• Call Stack
• Break on exceptions
• Continue / Pause

For testing, I used an STM32C071KBU6 running MicroPython with SPI and PWM on a DUELink Holiday Tree: Holiday Tree | DUELink

Here is example source: micropython-vsc-extension/examples/stm32c07/chrismastree_example at main · ghi-electronics/micropython-vsc-extension

I'm interested in hearing from other STM32 + MicroPython users — what STM32 device are you using, and what would you like to see supported?
