- * Note: Alfawise screens use various TFT controllers. Supported screens
- * are based on the ILI9341, ILI9328 and ST7798V. Define init sequences for
- * other screens in u8g_dev_tft_320x240_upscale_from_128x64.cpp
- *
- * If the screen stays white, disable 'LCD_RESET_PIN' to let the bootloader
- * init the screen.
- *
- * Setting an 'LCD_RESET_PIN' may cause a flicker when entering the LCD menu
- * because Marlin uses the reset as a failsafe to revive a glitchy LCD.
