The R/W pin of LCD is connected directly to the /W pin of MCU. The Enable pin of LCD is connected to one of the outputs of 74138 after inversion. This is also activated by the /W pin of MCU.
Hallo Raghunathan, why do you activate 74138 by WR# signal? May be that then the overlapping of CE# and WR# is to short? Bye, Kai |
