Hello Seeed Studio team, today I would need your help. I’ve been stuck on an issue for two days now.
I would like to use SquareLine Studio to create an interface for the Seeed Studio round display with the Seeed Studio ESP32-S3.
My problem is that I can transfer the screen visuals, but the touchscreen doesn’t respond. I think the issue is with the TFT_eSPI library. I tried configuring it, but I think I must have made a mistake somewhere.
For your information, I’ve already checked some problems, and they don’t seem to be related to:
cpp
Copier le code
bool touched = tft.getTouch( &touchX, &touchY, 600 );
In the example library, the hardware test file works fine.
Here are the sections I’ve modified, and maybe you can spot some errors.
TFT_eSPI.h:
cpp

/***************************************************************************************

#define TOUCH_CS 4
#ifdef TOUCH_CS

#if !defined(DISABLE_ALL_LIBRARY_WARNINGS)
#error >>>>------>> Touch functions not supported in 8/16-bit parallel mode or with RP2040 PIO.

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins
#define TFT_MISO 8
#define TFT_MOSI 9 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 7

//#define TFT_BL 22 // LED back-light

//#define TFT_WR 22 // Write strobe for modified Raspberry Pi TFT only

Thank you for your valuable advice!
