Hi everyone,
rencently I wanted to connect TFT LCD 1.8 inch display from Waveshare to Arduino Mega 2560. But all it does is displaying white screen. I've been trying for hours to wire it correctly, but it still does not work. I had connected it to Arduino Uno and it worked. Both boards are original. Can somebody tell me what's the problem or correct wiring?
Since you supply no information that we can use to help you, I am forced to guess. I hate guessing, but do you know that the SPI pins are different for the Mega than the Uno?
What, exact, display do you have?
Post your code. Read the forum guidelines to see how to properly post code and some information on how to get the most from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.
Post a schematic of how the wiring should be.
Post photos of how the wiring actually is.
Sorry, but I am not able to post code until Sunday. I know that pins are different. I think it can depend on communication voltage
