🦀60 lines of Rust - STM32 GPIOs and Interrupts

In this video I build a manufacturing test application for my Software Defined Retro ROMs in just 60 lines of Rust using embassy-rs. I cover:

All of the steps required to set up an embedded STM32 Rust project from scratch.
Developing with asynchronous embassy tasks.
Using the defmt and RTT logging frameworks.
Driving an LED with an output pin.
Detecting input pin state changes with interrupts.
Flashing and testing using probe-rs.
