Usage With Audio Board Connections
To use the ILI9341 display with the Audio Board, connect the signals using the alternate pins shown above. In setup() before calling TFT.begin(), use SPI.setMOSI(7) and SPI.setSCK(14) to configure the SPI library for these alternate pins.
#define TFT_DC 20
#define TFT_CS 21
ILI9341_t3 tft = ILI9341_t3(TFT_CS, TFT_DC);
void setup() {
SPI.setMOSI(7);
SPI.setSCK(14);
tft.begin();
