#189534 - Reset Circuit
Responding to: Rohan Dey's previous message
Oliver Sedlacek said:
You may not want a proper reset circuit but you always need a proper reset circuit. Get over it.

I think you misunderstood me. What I meant was if I reset the uC externally then the thing starts working. By just powering the 2051 uC it does not work.

You omitted to mention that in your cross-post

I figured that out after posting in the Keil forum

Any idea how to get this thing working. If I can't get this thing working on 89C2051 then I have to move to a different 8051 uC which is low cost with at least 6 i/o, 4K Program Memory and works on 5V input. Any suggestion on this behalf is also welcome.
