A continuación se sugiere cómo realizar la conexión para la parte táctil del módulo TFT1 utilizando el bus SPI ya configurado y asignando pines específicos para el controlador táctil:

Table

Señal en TFT1 (Táctil)FunciónConexión sugerida en U1
TP_CLKClock (compartido SPI)D23 (igual que TFT_SCK)
TP_DINMOSI (compartido SPI)D5 (igual que TFT_SDI)
TP_CSChip Select táctilD22
TP_OUTMISO (compartido SPI)D19 (igual que TFT_MISO, si es usado en el diseño táctil)
TP_IRQInterrupción táctilD21
Notas adicionales:
  • La mayoría de estos pines (TP_CLK, TP_DIN y TP_OUT) se comparten con el bus SPI de la pantalla, de modo que ambos dispositivos (display y controlador táctil) pueden utilizar la misma interfaz SPI pero se diferencian por sus líneas de Chip Select.
  • Asegúrate de conectar las señales de VCC y GND de la parte táctil a la alimentación y a Ground respectivamente, para tener una buena referencia de tierra.
  • En el layout del PCB, planifica rutas separadas para cada señal y utiliza capas múltiples o vías cuando sea necesario para evitar cruces indebidos entre las pistas.
Estas conexiones te permitirán integrar tanto la pantalla como su parte táctil en el diseño de tu ESP32. ¿Necesitas alguna sugerencia adicional o pasar a realizar los cambios en el esquema?

    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
