Hi all, I've just built myself a pair of jeenodes. The RF test has worked perfectly. Now I'm having problems with the LCD module. I'm running the lcd_demo sketch, the back light turns off and on, but that's all. No text. I unplugged the 2x16 display I bought from Jeelabs and tried the 4x20 display I have from Moderndevice, exactly the same happens, backlight flashes, no text.
I'm not sure if I've got something linked wrong on the lcd driver board, there aren't really any "if you want this, do this" instructions.
I have the logic set to +3 I have the light set to +3 I have the backlight resistor pad bridged.
There are some pads labeled SW, which I have done nothing to... no idea what they are.
