#118962 - Assumes you can read from the LCD Responding to: ???'s previous message |
but in those cases, that's what we do: Wait for BUSY to go away then start issuing commands, without unnecessary duplication (E.g. multiple Function Set commands). And it works -- if that's what you wanted verification of.
Unfortunately, due to budget and pin constraints, there are times we tie R/W* to ground and have to use wait loops instead of reading the BUSY flag. HOWEVER, in your code, I think you want to de-assert EN otherwise you are just reading the same value over and over, non? GB |
