Hi.. I have arduino uno with smartGPU2 3.5" (480x320)... I have tried many many many times to make the screen boot up but with no success.. here the steps of what I did: 1- downloaded the arduino IDE 1.0.5 2- downloaded the smartGPU lib. 3- uncomment the proper line from the libraries. (mine was 480x320) 4- added them to arduino software.
then I connected the wires as the following:
| [u]Arduino[/u] | | [u]SmartGPU[/u] | | - | - | - | | TX | | RX | | RX | | TX | | GND | | GND | | 3.3V | | 3.3V | | PIN13 | | RESET |
then I downloaded one of their examples (sketches) from the website (http://sourceforge.net/projects/smartgpu2arduinoexamples/?source=navbar)
I am still getting black screen on the LCD despite all my effort. (also I removed all the wires but I kept the VCC and GND, but with no success) (also I downloaded the Arduino 1.5.6 Beta.. but with no success)
am I missing something or is there a problem with my LCD? please advice..
