Topic: Nokia 5110 PCD8544 + Due -> display not working (Read 1 time) previous topic - next topic


Dear all,

I am trying to connect a 5110 LCD with PDC8544 controller to my Due and I cannot get it to work. I have connected the pins of the board to the Due as described in the playground tutorial. I also have a Mega 2560, and on that board including current limiting resistors it works perfectly. I first thought that the problem could be the init procedure so I tried different values of Vop (as suggested in the comments on the sparkfun website) but this does not give any effect (the display remains blank). Am I doing something wrong here, any suggestions how to get it to work?



I  put a line for setting sclk  to low  just before or below reset routine. It works fine for Arduino  due board only.
