Hi, I am fairly new to Arduino and ESP.
I want to make a monitoring system using esp32 cam and an SPI TFT LCD.
I have hardwired the TFT to the ESP32CAM and checked with some example code, the tft is working.
I also checked the camera stream, which is working and I can view the stream using its IP through wi-fi.
Now, I want to stream the output of the camera to the TFT directly, WITHOUT wi-fi involved. 10 to 20 FPS would be OK, better if higher can be done
The TFT LCD module I am using is 2.0 Inch SPI TFT LCD Color Screen Module ILI9225 Serial Interface 176 x 220
ESP32CAM module wiring is done as below
TFT ESP32CAM
VCC- 5V
G -- G
SDA- 13
CS - 15
CLK- 14
RS - 2
RST- 4
My code to check ESP32CAM for TFT is:
#include "SPI.h"
#include "TFT_22_ILI9225.h"
#include "math.h"
#define TFT_RST 4 //16 //4
#define TFT_RS 2 //12 //2
#define TFT_CLK 14
#define TFT_CS 15
#define TFT_SDI 13
#define TFT_LED 0 // 0 if wired to +5V directly
#define TFT_BRIGHTNESS 100 // Initial brightness of TFT backlight (optional)
//TFT_22_ILI9225 tft = TFT_22_ILI9225(TFT_RST, TFT_RS, TFT_CS, TFT_LED, TFT_BRIGHTNESS);
TFT_22_ILI9225 tft = TFT_22_ILI9225(TFT_RST, TFT_RS, TFT_CS, TFT_SDI, TFT_CLK, TFT_LED, TFT_BRIGHTNESS);
