Introduction

The 3.5” 320x480 TFT LCD driver is ILI9488, it uses SPI for communication with ESP32, the SPI main clock could be up to 60M~80M, make the display smooth enough for videos; and the camera OV2640 with pixel 2M, with this camera, you can make applications such as remote photography, face recognition…. While the camera not used, you can freely use all these pins with the breakout connectors, to connect the ESP32 display with sensors/ actuators, suitable for IoT applications.

Draw on LCD

1. You can get the code from here: Core
2. Open the file “\Project_Touch-Screen-Camera-master\touch_draw_v2\touch_draw_v2.ino”. Select the screen type used and comment out the ones that are not used.

//Choice your touch IC
#define ESP32_SDA 26
#define ESP32_SCL 27

//#define NS2009_TOUCH   //Resistive screen driver
#define FT6236_TOUCH    //Capacitive screen driver

3. Verify it and upload.
