Blink led with 2 multithread, sinch problems
Hi all,
I'm starting a new app with two threads.
If I run as debug step by step it works great.
But if I run free on the board, the second thread not works good (it doesn't blink the required times).
I've use CubeMX for the code generation with Time Base TIM1 as indicated below
What is the problem?
Thanks
