Hi,

Thank you for the information. Actually, I increased the size of the stack and heap because I had many function calls made (up to 16 as far as I could notice) and when I checked when stuck some global variables value they were not at all coherent so I believe they were crushed by some overflow !

I have a question regarding the usleep function though. In our first implementation we used the usleep function from within the interrupt handler of the timer. It is written in the HAL reference document that usleep is not available from within an ISR. While reading the usleep actual code am I not sure why this is the case ! Could some one provide some information about usleep ?

Best regards,
