Wiki Link : ESP32-S2 Parallel TFT with Touch(3.5'')

The 3.5" 320x480 TFT LCD driver is ILI9488, it uses 16bits parallel line for communication with ESP32-S2, the main clock could be up to 20MHz, make the display smooth enough for videos; You can freely use some of Mabee pins(A I2c and a IOs) with the breakout connectors, to connect the ESP32-S2 display with sensors/ actuators, suitable for IoT applications.

Feature

Integrated ESP32-S2 with 2.4G WiFi
Wi-Fi Protocols: 802.11b/g/n(802.11n up to 150Mbps),A-MPDU and A-MSDU aggregation and 0.4us guard interval support

Arduino Compatible: You can play it with Arduino IDE
LCD 3.5 inch Amorphous-TFT-LCD (Thin Film Transistor Liquid Crystal Display) for mobile-phone or handy electrical equipment
LCD Driver: ILI9488(16bits parallel line)
LCD Resolution: 320*480
FT6236 Series ICs are single-chip capacitive touch panel controller IC with a built-in 16 bit enhanced Micro-controller unit (MCU)
NS2009: A 4-wire resistive touch screen control circuit with I2C interface, which contains A 12-bit resolution A/D converter
Power supply: 5V, Type-C USB
Micro SD card slot on the board
Dual USB Type-C: one for native USB and one for USB-to-UART
Two Mabee interfaces
Board size: 66mm * 85mm

Code Explain

Complier Option

Install board : ESP32 .
Install library : LovyanGFX library.
Edit the code based on the touch screen. If you use resistive screen, choice NS2009_TOUCH. If you use capacitive screen, choice FT6236_TOUCH.
Use type-c use cable connect USB-TTL to PC.
Upload codes, select "ESP32-S2 DEV Module" and "UART0"

Firmware

SD16_3.5

Factory firmware. First run the boot self-test to check the hardware. Press down the middle of the touch screen as prompted to display a LOGO picture on the SD card. Finally, print the touch coordinates in the serial port.

Example

Simple Test

Three frame rate tests and SD card read and write tests.

FillScreen

Graph

Touch

PWM_backlight

Use pwm control screen back light.

Display Demo

The display of 5 display effects is modified from Lovyan's example. There are also two homemade demonstration videos: ultrasonic ranging and line charts.

Wifi Img

Receive TXT and BMP files over WIFI and display them on the screen.

Added a WiFi bulletin board app. You can upload and browse files in the SD card through the web page. And the latest uploaded BMP or TXT display on the 3.5-inch screen.

Library Install：esp32-micro-sdcard and esp32-webserver
Upload .\example\wifi_img_16\wifi_img_16.ino
Insert the SD card and power on.
Enter the IP address on the screen in your browser.

Select TXT or BMP to be uploaded. BMP must be 480 x 320 pixels, 24 bits.

Upload.
Wait seconds, the content is displayed on the screen.
