4Display-Shield-22 Arduino Shield
The shield utilises the SPI bus connected to the Arduino, which are MOSI pin D11, MISO pin D12 and
SCK pin D13.
The shield includes a uSD card socket, to provide the Arduino the means to access data stored on a
uSD card. The uSD SPI Card Select pin is D10.
The display on the 4Display-Shield-22 has an SPI interface, which is shared with the uSD card socket.
The Display Card Select pin is D7.
The display utilises an RS pin for selecting if data is written or if a command is written the display,
utilising pin D8.
There is also a display Reset pin which utilises pin D14 (A0).
The control of the LCD Backlight is done with pin D9, which can have PWM applied to it if desired to
adjust the brightness of the display.
The 4-wire Resistive Touch utilises pins D15 (A1), D16 (A2), A3 and A4.
