I am able to write to the display (20x4) but unable to read any characters out. I would like to use the ohm symbol and a few others. The last result has been an all dark segment in the first position. I have tried different addresses from the ASC11 and the Japanese fonts columns, same result. At one time I did get it to show some stray garbage spread out across the entire screen. The R/W line is directly connected to RD2 and is DEFINED properly. Using a 16F877. Code snip....
LCDIN $F4,[Ohm] 'LCD ohm character to var Ohm
LCDOUT $FE,1 'Clear Screen
LCDOUT $FE,2 'Return Home
LCDOUT Ohm 'LCD show character ohm
This should put out the ohm symbol to the LCD?
Any ideas? Thanks ,RC.
