@badben
I know this thread is one year old but I am experiencing the same problem. I received my espruino pico last week and I am quite new to espruino at all. Started plugging things today ;-)
@graf Did you solve your problem?
I made the wiring exactly like in http://www.espruino.com/Pico+LCD+Hello+World and used the snipped from this page. Nothing happens. Only blue backlight.
