Help with TFTdisplay Driver IC: NT35510 SKU:MRB3973

[yhanchristian]

Hi, everyone!

I'm trying use ESP32 S3 Dev Kit with a TFT Display SKU:MRB3973 like this model: http://www.lcdwiki.com/3.97inch_16BIT_M ... KU:MRB3973.

I use esp-iot-solution screen component to integrate with NT35510 controller and my code compiles, but the display doesn't work only shows a black SCREEN and doesn't draw a pixel in red color, like my code example to test it.

Follow my code in github to check: https://github.com/YhanChristian/Estudo ... ltzscooter

I've checked the hardware many times and didn't find an error in connections.

Anyone have worked with this display? What can I do to make it's work.

Best Regards,

One thought:

Some time ago I bought me another (SPI) LCD, which was one size bigger than the previous one, but had the same family of driver IC's and the same command set. I couldn't get the new one working until I spotted one tiny difference, the newer one does not support 16 bit pixel transfer (5-6-5), all pixels must be sent using 24 bits (8-8-8). I think more newer driver IC's have this issue.

Also I guess you checked the power supply? Whether it's configured to take 5 V or 3.3 V (sometimes configurable using a jumper/solder island).
