Hello,
I purchased a 2.8" Touch screen TFT on Amazon. I know i probably should've just purchased an adafruit TFT or something more well known but I'm still very new to coding and didn't really think there would be a difference.
I cannot seem to get the screen to function, I have tried many, many different libraries for different screen drivers as well as a few different wiring diagrams but so far I have only been able to get very faint looking bars on the screen which seem to quickly disappear.
Please help me figure out what to do next, I don't want to just chuck it in a box and let it collect dust so I've come here to get your opinions and advice.
Please let me know if you need more information and I'll be happy to supply it.
I can't see any code, I can't see any detail, and I just wasted 1.7 MB of my data plan on a pointless photo.
Did you try this library:
The display should work just fine. Since you're relatively new here, it's best to post code using code tags (read the 3 posts at the top of this Forum) since people are rightfully nervous about opening files here. Also, we need to know your Operating System and the microcontroller board you are using. Next, because your display supports the SPI interface, you should probably read up on that a bit, too. It helps if you tell us the chip that drives the display (e.g., ILI9341 mentioned above) as that will tell you which library you probably need to use. Finally, find a good image of the board you are using, like the one for the Nano shown here. If you look closely at the image and then study the pins the SPI interface needs to work properly (e.g., SDA), you can probably figure out which pins need to be connected to the display. Most libraries have example programs showing how to wire up the display and the code to demonstrate the graphics. Three's probably some videos, too. Spend a little time with these things and I'll bet you get it going.
Thanks for the info, I will try posting some more info tonight and I will give those suggestions a try.
