#49792 - Simple Digital Clock ---89C2051 |
Hi~
I am making a digital clock (hh-mm) with an at89C2051. I finished the main program part, (scanning display, second -> minute -> hour count...) Now I'm running the program on the 89C2051 and check the accuracy with my watch. After ten hours running, the clock running 10 sec faster than my watch. (which means, 1 sec/hour...) The 89c2051 output a pulse after it INC the "Second" digit, and it is a 1.000Hz pulse. Who have done this before and get the same problem? Stanley |
