TFT touchscreen with R61503 controller |
When i got it i realized that the controller is not the one listed and no libraries are available or at least i couldn't get this working. All i got is WHITE SCREEN. I tried using Adafruit libraries ( available here) which use to work with most of these modules and the excellent library from David (MCUFRIEND). All gave white screen.
The good thing is the above libraries and the touch screen information sketch (Here) reported that the module is having identifier 0x1503 and then a closer look at the shield also showed R61503 indicating the controller is different here.
Closer look at the pin details and driver information |
So hunted for the datasheet and after setting up the correct initialization, gave a nice working TFT
