#154033 - Damaged LCD? |
Hello,
I've been following the LCD tutorial in the 8052 book/webpage. Its been a great help so far. However iv managed to build the circuit for the LCD and written a program that i think should work. see below; http://www.ukvsmurfy.pwp.blueyonder.co.uk/LCD-TEST....D-TEST.txt however when i run the program the LCD displays this; http://www.ukvsmurfy.pwp.blueyonder.co.uk/270420080...008062.jpg It clear looks like there is some damage to the LCD in the bottom right hand corner, however my question is more to do with the top line of LCD where you can clearly see the 5x8 blocks solidly filled in. Is this normal? Or is it down to the damaged LCD or is this a problem with the code/hardware. Any advice or suggestions would be most grateful. The final and i guess most important question to me at the moment is that I was expecting the text 'Testing' to appear on the LCD should the code I've written do this? Thanks |
