I just started to play with this display and a netduino. It's my first project for a netduino, but i'm able to clear the screen, draw rectangles, and put a tweety face on the display. For the moment i'm using the 64k color mode, but i think i will later convert it for use with the 4k color mode. Unless i can speed things up. This display uses a hx8347 controller. I find the documentation not very easy to understand, but the source from watterot was a big help. Only problem i had was with the connector on the display board. It was making false contacts, so i had to solder it. For the background LED, i'm using a pwm output, so the light is adjustable. I did not start with the touch part yet.
Luc, the app works , I can display the tweety just fine thanks for sharing. I've been struggling to convert some mbed C code into C# without much success.
Couple of questions regarding the PWM: which pin are you using on the LCD side ( K or A ). 2) did you connect netduino pin directly to the LCD , or you're using some transistors in between ?
cheers, Alex
