3.5" TFT with breakout, white screen

by York333 on Tue Jan 08, 2019 11:17 pm

Hi, I spoke with support, and they sent me here to get help.

I recently purchased a 3.5 tft breakout, and the additional stmpe610 touch controller. I hooked the lcd up without the stmpe610 to make sure the screen was functioning. I have it wired correctly: 9 dc, 10 cs, 11 mosi, 12 miso, 13 clk, 5v Vin, gnd gnd, and 4 ccs. The solders are also good.

The screen lights up, but stays in "white screen." Occasionally the screen will flicker when the Arduino's led indicator lights up. I've tried sample sketches, and custom sketches.

I was planning on using these for 40 units. But I have to get it functioning first.

You're wiring for SPI mode. Did you solder the jumpers on the the display?

Sorry, I had to put this on the backburner for a few days.

Yes, I have the IM2 jumpers soldered together for SPI.

Thanks!

Post the output you get on the serial monitor when running the graphics test example as shown here:
