This repo contains the code for my YouTube class: "Bare Metal Embedded Software Development: Theory and Practice Using STM32". This course consists of around 25 video lessons. The URL is:

This course was developed using a ST NUCLEO-F401RE board. Since then, I ported the code to run on a ST NUCLEO-L452RE board. That code is on branch nucleo-l452re. Someday I might merge these two branches, and use #defines to select the board type.

If you do use the branch for STM32LXX, be aware there is a bug in the IDE for this case. I reported it here:

To workaround this bug, you have to change this generated line of code in main.c:

LL_RCC_HSI_SetCalibTrimming(16);

to:

LL_RCC_HSI_SetCalibTrimming(64);
