Pi Pico and unknown TFT

Projects Interfacing w/ Software on the Computer

Hi all,

I have received 2x 3.5 inch rpi displays, the type with the edge connector to plug directly into a rpi 3B for example. Now, what I would like to do is run this TFT from a pi pico using TFT_eSPI, but not knowing exactly which board it is has me chasing my tail to get even a simple "hello world" running on it.

This is a 480x320 display with XPT2046 touch controller.

I guess what I'm looking for is a bit of guidance as the sheer number and variety of screens, libraries, connections and methods is quite overwhelming.

I have it hooked up as per the following:

My time is quite restricted at the moment, otherwise I would bitbang this problem until I get something out!

Thanks in advance
Andy

luck ...turns out the TFT_eSPI setup files needed the following definitions uncommented..

#define ILI9486_DRIVER
#define RPI_DISPLAY_TYPE // 20MHz maximum SPI

With either/or library, it simply does not work and with both it just works. I will have to dig in and find out what RPI_DISPLAY_TYPE actually does.
