Hi.
I'm a newbie, and I want to build a simple RTC that counts from 1 to 60 seconds, and send the result to P1.

I began to work with the RTC example on the tutorial, the problem is when I run the program on the simulator seems working fine, but when I load the program to my evaluation boards, I got erratc behaivor on P1.

I have a couple of evaluation boards (one with philips 8052AH and another with an atmel 89C51)

Does ane can help me with this??
all I need is a couple of descriptive examples.

best regards
Carlos
