One difficulty with the STM32 is that they come in really small cases only. Not everybody can solder this, especially on a board with limited quality. One can do something like AVR or PIC18 on a prototype board - the STM32 essentially needs a professional made board with solder mask. --- End quote --- You can get boards from JLC for almost nothing and solder LQFP with 0.5mm pitch. --- End quote --- But in my country i can't order from JLC.(that's not a problem) |

I use Chibios for firmware. I don't use CubeMX because the code and API it generates is absolutely not to my liking. It's fine for led blinking, but when I tried more sophisticated programs I found Chibios much easier to use. Still difficult nonetheless. --- End quote --- I'm gonna do everything from scratch, that's all part of the fun(for me at least). If you just wanna get things running you'll probably be better of using something like Chibios like you're doing. But I've never been a fan of that, not that there's anything wrong with em I just like programming :) |
