#167937 - LCD timing Responding to: ???'s previous message |
LCD remains in its powerup mode. No init code getting to it.
I'm sure the fault lies in the PAL timing cause the 7825 ADC is not working either. LCD and ADC are the only peripherals being decoded by the PAL. I have a smartwatch DS1216 that works fine on the bus and its being decoded directly out of a 74ls156. Thanks, John |
