Tft 2.8 ili9341 con esp32 problema touch

j1jorge · December 6, 2023, 3:17am

Buenas noches, cominidad. les comento que he tenido incovenientes intentado realizar la utilizacion del touch de la pantalla tft 2.8 ili9341. he usado la libreria SPI.h
y TFT_eSPI.h. el cual da las instrucciones de modificar su User_Setup.

#define ILI9341_DRIVER       // Generic driver for common displays HABILITAR

// For ESP32 Dev board (only tested with ILI9341 display)
// The hardware SPI can be mapped to any pins

#define TFT_MISO 19
#define TFT_MOSI 23
#define TFT_SCLK 18
#define TFT_CS   15  // Chip select control pin
#define TFT_DC    2  // Data Command control pin
#define TFT_RST   4  // Reset pin (could connect to RST pin)
//#define TFT_RST  -1  // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST
#define TOUCH_CS 21     // Chip select pin (T_CS) of touch screen```

en cuanto a lo que se muestra en pantalla todo esta correcto.
pero cuando ingreso el test the touch controller no genera nada en el monitor serial
```#include <SPI.h>
#include <TFT_eSPI.h>
TFT_eSPI tft = TFT_eSPI();

//====================================================================

void setup(void) {
  Serial.begin(115200);
  Serial.println("\n\nStarting...");

  tft.init();
}

//====================================================================

void loop() {

  uint16_t x, y;

  tft.getTouchRaw(&x, &y);
  
  Serial.printf("x: %i     ", x);

  Serial.printf("y: %i     ", y);

  Serial.printf("z: %i \n", tft.getTouchRawZ());

  delay(250);

}```


si alguien me pudiera ayudar `Texto preformateado`

Intenta no comentar un código con texto que luego debe ser comentado para que sea funcional.
Puedes hacer los comentarios por fuera del código.

De donde sacate este ejemplo? Coloca el link por favor

buenas tardes... espero me puedas ayudar...

con este video segui paso a paso todo..
con referente a la pantalla todo esta perfecto. logra visualizar cualquier ejempo de la libreria.

en este el problema sigue siendo el touch en el circuito se debe conectar el TCS al pin 5 del esp32.

ya realice las modificaciones en las librerías como se comenta. pero sin tener repuestas en el touch. cuando ejecuto el ejemplo de Keypad el monitor serial solo muestra esto
15:20:45.411 -> !�0��!�!!�LN��h
las conexiones están tal cual el video..

En el monitor serie lo que ves se debe a que estas con una velocidad den baudios incorrecta.
Tu código dice

 Serial.begin(115200);

Asi que elige esa velocidad para el monitor Serie.

Que versión ESP32 estas usando, un ESP32 DEV Module u otro?

j1jorge · December 10, 2023, 2:30pm

buen dia ... ya he puesto la velocidad Serial.begin(115200);.. segun el codigo... pero sigo teniendo el problema de touch...
tambien utilice el codigo de test touch en la libreria de tft_espi. y deberia tener algun cambio en los valores del los ejes x y pero nada... solo quedan en 0 0.
es mas considere que podria ser el esp32 y probe otro y esta en la misma condicion... no funciona el touch...

este es el ejemplo que estoy usando

en este la velocidad para el moitor serial es 9600. pero eso ya lo domino y se que dependiendo el ejemplo debo cambia el valor del monitor serial...

Prueba esto, creo que es tu misma pantalla y justamente prueba el touch.

antonio_00 · December 18, 2023, 12:57pm

yo tengo el mismo problema, y con este vídeo tampoco se me soluciona. Uso una ESP32 dev kit, con los pines así:
CS: 2
MISO: 19
MOSI: 23
CLK: 18
RESET: 3,3V
LED: 3,3V
GND: GND
VCC: 3,3V
DC: 14
Y del touch:
T_CS: 15
T_DO: 19
T_DIN: 23
T_IRQ: 35
T_CLK: 18.
Uso los códigos de ejemplo de la librería TFT_eSPI. Por pantalla se muestra todo perfectamente, lo que no funciona es el touch, si está la pantalla funcionando.
Si desconecto los botones de la pantalla, el touch si fucniona.
Muchas gracias!!

pero te entiendo, en el segundo ejemplo usa Adafruit para la pantalla que no es problema pero usa

#include "SPI.h"
#include "Adafruit_GFX.h"
#include "Adafruit_ILI9341.h"
#include <XPT2046_Touchscreen.h>

para el touch, eso lo probaste?

antonio_00 · December 19, 2023, 8:15am

Siiii, lo he probado pero nada. No sé si habrá un conflicto en el puerto SPI o qué pasará

antonio_00 · December 19, 2023, 10:10am

vale a mí ya me funciona, muchas gracias!!!!!

Surbyte · December 19, 2023, 5:32pm

Has visto!!!! Justamente te lo propuse porque usaba otra librería. Ese era el punto.
A veces uno se atasca queriendo hacer funcionar algo que no funciona.
Cuando veas un video de Youtube, mira de cuando es, todo lo que tenga 2 años es viejo, pero lo que te dice si funciona o no, es la actualización de la librería.
No uses cosas viejas que no se actualizan.

antonio_00 · January 8, 2024, 2:48pm

De acuerdo, muchas gracias!
