Hi Gordon,
Yes it displays a solid bar on one line on a 2 line display. Its definitely hooked up to the +5v on the STM32F4 board and RW is connected to ground.
I have tried other pin combinations already with no success at all. All that seems to happen is the solid bar of pixels dims ever so slightly when the code has been run which happens whatever pins I choose.
Ill double check everything again.
Thanks for your help.
Regards
Dan
