#187723 - what's on P2 is not that intersting initially, ... Responding to: ???'s previous message |
But in circuits which have problem i do not take anything in Hyper Terminal and checking the circuit i measure something strange. I measure with oscillator the ports of high byte adress in Port2 and i see that all take some time level hig
what's on P2 is not that intersting, that can depend on the capabilities of your "oscillator" :) what's on the other side of the address latch is what you want to check first. before reposting state what oscilloscope you have, and, if not a common brand, state the bandwidth and analog/DSO Erik |
