*Check connectivity of the connection using a multimeter
*Check for shorts
If everything mentioned above is right then, your controller might be at the problem.
to check controller:
*Check reset circuit using a CRO (Must show a High->Low pulse)
*Check crystal (you will get a sine wave)
If your controller is also ok! then.. the problem is unpredictable. I hope after the first checking everything will be ok.]]> contact@nospam.com (Ajay Bhargav) Tue, 08 May 2007 08:34:59 -0700 http://www.8051projects.net/forum-t612.html
