HI, thanks for the reply,

I have got make some test with the LED output, all get right before the PWM instruction (i make the LED blinking) but it seems that the program freeze after. I can post all the test i have made but it's only a bigger program.
I have never got any PWM signal.
I have posted the entire program to let you see what i want to do.
I want to drive a motor with variable speed and verifying if it stops by controling his current.
