Topic: Nokia 5110 PCD8544 + Due -> display not working (Read 2916 times) 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.


Wow the SCLK LOW definitely worked for me too!  Outstanding!  Thank you!
