hey, I see from the Netduino forums you’re in Wellington, NZ. I’m in Sydney AU. I also see you’re 14, so it’s not a uni assignment unless you’re a real smart cookie and got an early place - and good on you if you are
Anyway, I had a quick look on your onedrive. My first comment is I reckon your GND wire isn’t soldered properly, and I’d re-solder that. The R- wire also has a bit of a bulge on the solder so you might want to clean the soldering iron tip and then hit it with the iron and have it reflow and take up some of the solder onto the tip, just to clean it up.
Can you tell us if you have access to a multimeter ? That might help troubleshoot the issue - I’d first forget the driver, and start simple by toggling a pin and measuring each signal on the LCD.
From there, I can’t comment on the Netduino helper code (I didn’t know where to start diving into the folder structure !) But I honestly think the initial problem you’re having is wiring. Lets get past that bit and then talk software.
PS: I’ll be online for the next few hours and will check back to see if you’ve updated things here
