#144967 - OK so why was the LCD blank? Responding to: ???'s previous message |

Yes, the data of port was given to hex to ascii converter.Eg
if the data was 1EH it would generate two ascii codes for 1 and E and send it to lcd to display it.So we would read the original data at port and not its ascii value. OK, so why was the LCD blank when it was supposed to display the manufacturer ID? JW |
