#77230 - RE: ALE vs LED Responding to: ???'s previous message |
Christian Kleiber said:
if ALE oscilates then uC must be working That's probably a good assumption. The next step is to verify that it is actually executing code - which is where a code-controlled LED comes in. The next step is a simple "Hello, world" program to show that the serial port & RS232 transceivers are working & correctly connected. Then he can get down to debugging his keyboard code... |
