#162954 - Speaking the Truth....... Responding to: ???'s previous message |
I have connected LCD and RTC pins to the same port0. The only means of disabling RTC while accesing the LCD is by the !cs(<---P2.5) pin of RTC.
Previously I have done RTC programming sucessfully taking it to an External memory. with this fact clear I have proceed for PCB. Now trouble is knocking my door in the form of !cs. |
