<working> Waveshare ESP32C6 Touch LCD 1.47

[Slopert1]

I have created a device defenition for this board. It runs the PDQ example.

added to Arduino_GFX_dev_device.h:

#elif defined(WAVESHARE_ESP32_C6_TOUCH_LCD_1_47)
/* https://www.waveshare.com/wiki/ESP32-C6-Touch-LCD-1.47 */
#define GFX_DEV_DEVICE WAVESHARE_ESP32_C6_TOUCH_LCD_1_47
#define DEV_DEVICE_INIT()                  \
    {                                      \
        pinMode(4 /* SD_CS */, OUTPUT);    \
        digitalWrite(4 /* SD_CS */, HIGH); \
    }
#define GFX_BL 23
Arduino_DataBus *bus = new Arduino_HWSPI(15 /* DC */, 14 /* CS */, 1 /* SCK */, 2 /* MOSI */, 3 /* MISO */);
Arduino_GFX *gfx = new Arduino_ST7789(bus, 22 /* RST */, 0 /* rotation */, false /* IPS */, 172 /* width */, 320 /* height */, 34 /* col offset 1 */, 0 /* row offset 1 */, 34 /* col offset 2 */, 0 /* row offset 2 */);```

In PDQgraphicstest.ino I had to add some strange code (from their own examples).

void lcd_reg_init(void) {
static const uint8_t init_operations[] = {

BEGIN_WRITE,
WRITE_COMMAND_8, 0x29,  // 5: Main screen turn on, no args, w/delay

};
bus->batchOperation(init_operations, sizeof(init_operations));
}

And call that right after the GFX is initialized.
Added below right after that to get rotation and text readable.

`
lcd_reg_init();
gfx->setRotation(2); // orientation of usb connector when readable 0:bottom 2:top
gfx->invertDisplay(true); // invert colors
`

From the documentation is should be a JD9853 chip? I have not tested the card reader. Sorry for the messed up layout.
