STM32 with libopencm3 - Part 1: Simple Timer	2020-02-12	2020-02-12	true	libopencm3 stm32 tutorial	Tutorial	false	false

After having reviewed part 0 of this series, we can now explore controlling GPIO with the hardware timers! Other tutorials have used the Systick timer as a good introduction to adding a delay for blinking an LED. However, it is my belief that this leads to confusion for beginners and only opens the door to misunderstandings. That being said, we will be using timers and their associated GPIO ports with Alternate Function modes.
