Graphics & Touch on WT32-SC01

• Board : WT32-SC01 from Wireless Tag (Seeed Studio also carries the same)
  Similiar display from DFRobot uses ILI9488 (not ST7796S)
• Graphics & Touch Driver : LovyanGFX
• UI/Widgets : LVGL8.x
• Framework : Arduino + PlatformIO (ESP-IDF sample here)

Demo code output

WT32-SC01 Specs

Pros:

• ESP32 WROVER-B
• 3.5" 480x320 ST7796S TFT Display
• Capacitive touchscreen FT6336U
• Default 4MB Flash & 8MB PSRAM
• Two external expansion female pin headers with same pin-out (mirrored)
• 2 x 3.3v LDO, 1 for the board and 1 for the external expansion
• Separate Battery/External power option with voltage range 5v-9v
• USB-C for power and programming

Cons:

• No SD Card storage option
• 16MB Flash version available but only through Alibaba (didn't know when I ordered)
• Pin headers are 2mm pitch which is not breadboard standard (2.54mm is common).
• Mounting holes in the wrong place so you cannot use it (fixed in newer revisions)

Board config

• TFT (ST7796)
  • TFT_RST=22
  • TFT_SCLK=14
  • TFT_DC=21
  • TFT_CS=15
  • TFT_MOSI=13
  • TFT_MISO=-1
  • TFT_BCKL=23
• Touch (FT6336U)
  • TOUCH_SDA=18
  • TOUCH_SCL=19
  • I2C_TOUCH_ADDRESS=0x38

Touch and Draw sample (without LVGL)

Replace the content of main.cpp with the following to test quickly
For Ardiuno IDE, install LovyanGFX library then copy & paste the below code into your .ino file and flash!

/*
    Simple Touch Drawing sample for WT32-SC01
*/
#define LGFX_AUTODETECT     // Autodetect board
#define LGFX_USE_V1         // set to use new version of library

#include <LovyanGFX.hpp>    // main library

static LGFX lcd;            // declare display variable

// Variables for touch x,y
static int32_t x,y;

void setup(void)
{
  lcd.init();

  // Setting display to landscape
  if (lcd.width() < lcd.height()) lcd.setRotation(lcd.getRotation() ^ 1);

  lcd.setCursor(0,0);
  lcd.printf("Ready to touch & draw!");
}

void loop()
{
  if (lcd.getTouch(&x, &y)) {
    lcd.fillRect(x-2, y-2, 5, 5, TFT_RED);
    lcd.setCursor(380,0);
    lcd.printf("Touch:(%03d,%03d)", x,y);
  }
}
