6 GPIOs are required to drive the SPI display. One additional GPIO is needed for the XPT2046 touch sensor. Including the Vcc and Gnd pins, a total of 12 connections need to be made to the MCU:

~~By default, pin 4 is normally connected to 5V. This turns the display backlight LED on all time. In order to control the backlight you can drive pin 4 of the display using a PNP transistor. The electronics circuit needed is not part of this diagram.~~
SPI MISO, MOSI and SCLK are shared between the touch controller and the lcd controller.

You need to desolder the 0R resistor on the back side of the panel from the 16-bit position. Then resolder the 0R resistor in the 8-bit position.
There are no pins shared between the touch controller and the lcd controller.

## WaveShare 4.0" RPi LCD (rev C)
6 GPIOs are required to drive the SPI display. One additional GPIO is needed for the XPT2046 touch sensor and one extra GPIO for backlight dimming.
Including the Vcc and Gnd pins, a total of 13 connections need to be made to the MCU:

25 |Module Ground |GND | |GND
26 |Touch Chip Select |GPIO22 |TOUCH_CS |TP_CS
!> (*)Only the WaveShare 4.0" RPi LCD Revision C has a solder jumper on the back to enable PWM backlight dimming.
Other revisions of this board do not have this feature.
SPI MISO, MOSI and SCLK are shared between the touch controller and the lcd controller.
