Hi, at the moment the digital sensor ports 3 and 4 do not work on the cortex I am currently using. Can anyone please make a suggestion on how to fix this problem?


Additional information:
I have already proven that the sensors are fine (with other sensor ports) and that the real troublemakers are these two ports.

Can you describe what you're trying to do on the sensor ports (what sensors you're using, ect) and what you mean by "do no work"? Additional detail will help me figure out what might be going on.

One suggestion: Try redownloading the ROBOTC firmware to the microcontroller.
