Hmm.. I just clean compiled with

#define ESP32_Variant 7 // ESP32 Dev Module with ILI9341 2.8" colour TFT SPI 240x320

Could you try with my config.h, and then compare with yours?

It would be best if you could use the latest source, so we are on the same page.

[Cyberdemon-23]

Downloaded the latest source, your config file - is the same error. Where is HUD_ARROW_OFFSET written? Maybe the wrong library is being used?

I see I added that code in V2.18.0. I can check it out a little later.

[zs6buj]

When I checked it this morning, it did not compile, my apologies. (told myself to go sit in the corner)

It's fixed in V2.19.05.

[Cyberdemon-23]

is actually compiling now, but the screen is not displaying anything. See if everything is properly connected

[zs6buj]

Hmm. I see you have marked the LED pin with 5v, so you know that both Vcc and LED must be powered.

Could you try these pins:

#define ILI9341_Display         // ILI9341 2.8" COLOUR TFT SPI 240x320 V1.2  
#define SCLK          18        // blue wire on my test setup
#define MOSI          23        // yellow wire
#define CS            25        // white wire
#define DC            22        // green wire
#define RST           21        // brown wire

[zs6buj]

I just tested it with the original pins, and that also works:

#define ILI9341_Display         // ILI9341 2.8" COLOUR TFT SPI 240x320 V1.2  
#define SCLK          18        // blue wire on my test setup
#define MOSI          23        // yellow wire
#define CS            25        // white wire
#define DC            26        // green wire  

#define RST           27        // brown wire
// LED=3.3V,  Vcc=5v,  Gnd 
// MISO                not used by Adafruit     

Could you double check your wiring?

If you could post the serial monitor log it might be helpful to see if there are any startup anomalies.

"E (147) psram: PSRAM ID read error: 0xffffffff"

This looks a bit suspect. I googled it and got this:

"One of my ESP32-Cam boards has this issue too. Is the most likely explanation hardware failure of the PSRAM chip?"

EDIT: removed unrelated comment

Uploaded to another board - this error disappeared, but the screen remained white. I change Adafruit_ILI9341 display = Adafruit_ILI9341 (CS, DC, RST); // LED = 3.3V, Vcc = 5v, Gnd on the Adafruit_ILI9341 display = Adafruit_ILI9341 (CS, DC, MOSI, SCLK, RST); now everything works!

[zs6buj]

I'm guessing that I'm one version behind of the Adafruit ILI9341 library.

[zs6buj]

I updated to 1.5.10, but observing the two versions of the object,

Adafruit_ILI9341 display = Adafruit_ILI9341(CS, DC, RST); is far faster. Refresh of the display is very fast, but with

Adafruit_ILI9341 display = Adafruit_ILI9341 (CS, DC, MOSI, SCLK, RST);

refresh is slow. Too slow to refresh to HUD fast enough. I think maybe this version renders the display in main RAM (on the stack), and it is slower. Guessing here.

[zs6buj]

First is hardware SPI, and the second is software SPI

[Cyberdemon-23]

the problem was in the wires, they were of poor quality. Now it works with Adafruit_ILI9341 display = Adafruit_ILI9341 (CS, DC, RST); Thank you very much!

[zs6buj]

Cool! My pleasure CyberD.
