2.8 TFT touch problem

[alphalneo]

Hi
I bought all in one TFT 2.8 with ESP32, I am able to use the display but not the touch using the TFT_eSPI

I configured like this

#define TFT_MISO 12
#define TFT_MOSI 13 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 14
#define TFT_CS   15  // Chip select control pin
#define TFT_DC   2  // Data Command control pin
#define TFT_RST  -1  // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL   21  // LED back-light

#define TOUCH_CS 33     // Chip select pin (T_CS) of touch screen

However, the touch clock, for example, is using a different pin

I tried with TFT_TOUCH with this setting

#define DOUT 39  /* Data out pin (T_DO) of touch screen */
#define DIN  32  /* Data in pin (T_DIN) of touch screen */
#define DCS  33  /* Chip select pin (T_CS) of touch screen */
#define DCLK 25  /* Clock pin (T_CLK) of touch screen */

And the touch is working

Can I use the TFT and Touch with TFT_eSPI? and the most important how?

You say the "touch is working". So what is the problem?

[alphalneo]

The touch doesn't work with the tft_eSPI I added tft_touch in order to have it working
Therefore, the hardware for the touch is working, but I am not able to use it with tft_espi

Check that TOUCH_CS is really being seen. I not sure of your Tool slow but with Platformio, I had to set it in User_Setup.h in the library with my recent tests.

The touch controller must be on the same SPI bus as the display but with a separate chip select. Note also that you may need to disconned the TFT_SDO pin on some displays, see here.

Thank you I will try to modify the circuit

[smoochiee]

Have you modified your circuit?im having same problem

[alphalneo]

Yes I did, I cut the touch screen connection and wired to the display
And now is working
