Hello every one.
I have a problem with my LCD. It does not show anything ?
What I’m trying to do is to write a word to 16X2 HD44780U
Using a GPIO _ Expansion board from Phytec and the microcontroller is ADuC812
I read the LCD tutorial over here but still was not able to make work the problem is the controlling line how to EQU them.
The RS line is connected to A2 and the RW to A1, the EN line is connected throw 7402 IC to (RD, WR, and CS2)
So how can I declare in assembly A51 them any advice??
Thank you
