ILI9340 Display driver¶
Overview¶
Every half-second, this sample application draws a color-filled rectangle in a corner of the LCD display. The rectangle fill color cycles through red, green, and blue on each update.
Wiring¶
The NUCLEO-L476RG should be connected as follows to the Adafruit TFT display.
