Hi,
I can't program the GPIOs
levels don't change and stay in reset mode, what's the problem?
I use the HAL STMF4
Maybe you help me please!!!
Thanks for the advance!
Not much info you're giving us. Here are some possibilities, in order of likelihood:
- Code bug (show your code, or go from an example)
- Misunderstanding (perhaps you are monitoring the wrong pin, or the pin isn't connected how you think.)
- Hardware issue (solder bridge, broken trace, cold joint, etc.)
Consider going off of an example and adapt it for your board:
