I am trying to use the smart LCD controller. My printer uses marlin firmware and a Rambo board. I modified the fastio.h, configuration.h and the pins.h as per the instructions I found on line (http://reprap.org/wiki/RamboLCD) and uploaded using the arduino 1.0.5 IDE.. All I am getting in the LCD screen is two horizontal lines made up of blocks. Contrast does not help. Anybody Sucessfully use this LCD with the Rambo?
My neighbor had pretty much the same result trying to use the same LCD on a Mindel max also with a Rambo so I am sure we are doing something wrong. Any help would be greatly appreciated. I can upload the modified files is anyone has an interest in looking at them.
