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: [Select all] [Expand/Collapse]

1. #include "image.h"
2. #include <SPI.h>
3. #include <TFT_eSPI.h>
4. TFT_eSPI tft = TFT_eSPI();
5. #include <TJpg_Decoder.h>
6.  
7. #include <WiFi.h>  
8. #include <PubSubClient.h>
9. const char* ssid = "****";
10. const char* password = "****";
11.  
12. void setup_wifi() {
13.   delay(10);
14.  
15.   Serial.println();
16.   Serial.print("Connecting to ");
17.   Serial.println(ssid);
18.  
19.   WiFi.mode(WIFI_STA);
20.   WiFi.begin(ssid, password);
21.  
22.   while (WiFi.status() != WL_CONNECTED) {
23.     delay(500);
24.     Serial.print(".");
25.   }
26.  
27.   randomSeed(micros());
28.  
29.   Serial.println("");
30.   Serial.println("WiFi connected");
31.   Serial.println("IP address: ");
32.   Serial.println(WiFi.localIP());
33. }
34.  
35.  
36. bool tft_output(int16_t x, int16_t y, uint16_t w, uint16_t h, uint16_t* bitmap)
37. {
38.    // Stop further decoding as image is running off bottom of screen
39.   if ( y >= tft.height() ) return 0;
40.  
41.   // This function will clip the image block rendering automatically at the TFT boundaries
42.   tft.pushImage(x, y, w, h, bitmap);
43.  
44.   // Return 1 to decode next block
45.   return 1;
46. }
47.  
48.  
49. void setup() {
50.   delay(500);
51.   Serial.begin(115200);
52.   delay(500);
53.  
54.   Serial.print("TFT_MOSI: ");
55.   Serial.println(TFT_MOSI);
56.   Serial.print("TFT_SCLK: ");
57.   Serial.println(TFT_SCLK);
58.   Serial.print("TFT_CS: ");
59.   Serial.println(TFT_CS);
60.   Serial.print("TFT_DC: ");
61.   Serial.println(TFT_DC);
62.   Serial.print("TFT_RST: ");
63.   Serial.println(TFT_RST);
64.  
65.   tft.begin();
66.   tft.setRotation(1);  // 0 & 2 Portrait. 1 & 3 landscape
67.   tft.fillScreen(TFT_BLACK);
68.   tft.setCursor(0,0);
69.   tft.setTextColor(TFT_WHITE);
70.   tft.setTextSize(1);
71.   delay(5000);
72.  
73.   TJpgDec.setSwapBytes(true);
74.   TJpgDec.setJpgScale(1);
75.   TJpgDec.setCallback(tft_output);
76.  
77.   delay(1000);
78.   setup_wifi();
79.  
80. }
81.  
82.  
83. void loop()
84. {
85.   TJpgDec.drawJpg(tft.getViewportX(), tft.getViewportY(), image, sizeof(image));
86. }

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

Code: [Select all] [Expand/Collapse]

1. #define TFT_MOSI  13
2. #define TFT_SCLK  12
3. #define TFT_CS    14
4. #define TFT_DC    15
5. #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.
