STM32CubeMX configs and some notes to get started with STM32 development on the boards I own. Both IOC are configured to generate STM32CubeIDE projects.

STM32f103C8Tx aka BluePill

This directory contains a configuration for LED, USB (virtual COM port), both crystals (32kHz and 8MHz) and 72MHz HCLK

SWD connection info

SWD connector is
