Greetings, im vusing a TM4C123GXL launchboard and i found a strange problem.
After executting the next code, i can make first 4 times,that is light the 4 leds, 1 at a time and then when it reaches to the last condition, it goes to 0, but doesnt execute, and stops the code. I already had this in the interruption and was still worse, only could make 3 times and then stalls the program.
I can't find a solution to this. This will be used to change between modes of functioning.
