ESP32-CAM TFT display and Wi-Fi trouble

[genti91]

Hi, I am trying to use my esp32-cam with a TFT display and Wi-Fi at the same. If I use the display on its own it works fine and when I use Wi-Fi on its own it also works fine, but when I try to use them together it doesn't work.

This is my code:

Code: Untitled.cpp Select all

#include "image.h"

#include <SPI.h>

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

#include <TJpg_Decoder.h>



#include <WiFi.h>  

#include <PubSubClient.h>

const char* ssid = "****";

const char* password = "****";



void setup_wifi() {

  delay(10);



  Serial.println();

  Serial.print("Connecting to ");

  Serial.println(ssid);



  WiFi.mode(WIFI_STA);

  WiFi.begin(ssid, password);



  while (WiFi.status() != WL_CONNECTED) {

    delay(500);

    Serial.print(".");

  }



  randomSeed(micros());



  Serial.println("");

  Serial.println("WiFi connected");

  Serial.println("IP address: ");

  Serial.println(WiFi.localIP());

}





bool tft_output(int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t* bitmap)

{

   // Stop further decoding as image is running off bottom of screen

  if ( y >= tft.height() ) return 0;



  // This function will clip the image block rendering automatically at the TFT boundaries

  tft.pushImage(x, y, w, h, bitmap);



  // Return 1 to decode next block

  return 1;

}





void setup() {

  delay(500);

  Serial.begin(115200);

  delay(500);



  Serial.print("TFT_MOSI: ");

  Serial.println(TFT_MOSI);

  Serial.print("TFT_SCLK: ");

  Serial.println(TFT_SCLK);

  Serial.print("TFT_CS: ");

  Serial.println(TFT_CS);

  Serial.print("TFT_DC: ");

  Serial.println(TFT_DC);

  Serial.print("TFT_RST: ");

  Serial.println(TFT_RST);

  

  tft.begin();

  tft.setRotation(1);  // 0 & 2 Portrait. 1 & 3 landscape

  tft.fillScreen(TFT_BLACK);

  tft.setCursor(0,0);

  tft.setTextColor(TFT_WHITE);

  tft.setTextSize(1);

  delay(5000);



  TJpgDec.setSwapBytes(true);

  TJpgDec.setJpgScale(1);

  TJpgDec.setCallback(tft_output);



  delay(1000);

  setup_wifi();



}





void loop()

{

  TJpgDec.drawJpg(tft.getViewportX(), tft.getViewportY(), image, sizeof(image));

}

And this is how I have set up the display pins in the User_Setup.h of the TFT_eSPI library:

Code: Untitled.cpp Select all

#define TFT_MOSI  13

#define TFT_SCLK  12

#define TFT_CS    14

#define TFT_DC    15

#define TFT_RST  -1

WiFi initialization is the most power intense activity for a esp32. Try init'ing wifi before you power up the display.
For better assistance, explain what "doesn't work" means.
