Talking to an STM32 Nov 11, 2015
When dealing with ARM µCs and boards based on them, there’s always one big elephant in the room: how to upload software to them, and how to talk to them via serial or USB.
The available options, choices, trade-offs, and even just their properties can be staggering. This week’s article series is about what the problem is, an overview of the many different ways to address them, and how to get started with the minimal fuss and/or minimal cost.
On the menu for this week are four dishes, served on a daily basis:
- Most bare µCs are clueless - Wed
- Lots of chickens and eggs - Thu
- Bootstrapping a boot loader - Fri
- Making a Black Magic Probe - Sat
Fortunately, we’ll need very little to get going. We can pull ourselves up by our bootstraps!
