– Raspberry
Pi
I = Input, O = Output, P = Power
Note: The on board processor of the 4DPi-32-II utilises one of the Chip Select (CS) pins on the Rapsberry Pi’s
SPI Bus (SPI-CS0). There is SPI-CS1 still available for use by the User.
Note: The on board Touch Screen Controller utilises the I2C bus (SDA1, SCL1) to communicate to the Raspberry
Pi. The SPI Bus is capable of communicating with other devices also, so isn’t restricted only to the 4DPi’s touch
controller.
