Hi! I’m having the same problem that you explained a lot of time ago, maybe you’ve forgotten it but, what where the changes you made to the PCD8544 library?
I’m using an Arduino nano 328p, I have the LCD connected to pins 7,6,5,4,3 and the SD to MOSI – pin 11 MISO – pin 12 CLK – pin 13 CS – pin 10
I set the LCD library like this: LCD5110 myGLCD(7,6,5,4,3);
Hope you remember smthing! thanks a lot!!
