@uldara1 I have updated the develop branch and added support for GSLx680. Probably the I2C address is 0x40. Please give it a try.

@uldara1 I am glad to hear that it worked well. BTW, where was the firmware you uploaded?

@uldara1 Where did you find that firmware? I know almost nothing about GSLx680. If more than one type of firmware is needed, I would like to know why. Where did...

@uldara1 and, I would also like to know what product you purchased. Do you have a URL where I can purchase the same product?

@uldara1 Thanks for the information ! The develop branch has been updated. Four types with different firmware are available. ``` lgfx::Touch_GSL1680E_800x480 // GSL_1680E, 1688E, 2681B, 2682B lgfx::Touch_GSL1680F_800x480 lgfx::Touch_GSL1680F_480x272 lgfx::Touch_GSLx680_320x320 ```...

@uldara1 Perhaps GSLx680 will match the coordinates without calibration. If necessary, do the following ``` /// get calibrate data: uint16_t data[8]; gfx.calibrateTouch(data, TFT_WHITE, TFT_BLACK); /// check calibrate data: Serial.print("calibrate data:\n");...

@uldara1 Hmmm. I am also in the state of not knowing anything about the details of GSLx680, so I can't give you proper advice. My guess is that its firmware...

@daemondong I have arranged for SEPS525, but the handling of the flexible cable is a bit troublesome. I will eventually implement it when I get time to work on it.

@don41382 In the ESP32, the APB clock is 80MHz, so the clocks that can be set for SPI are 80MHz, 40MHz, 26.67MHz, 20MHz, and more... For the ILI9341, the practical...

The easiest way to use 80MHz with SPI is to use the ST7789. It can be used in much the same way as the ILI9341, but I think it will...
