Often advertised on eBay etc as an "upgrade to the Nokia 5110 display" (though completely incompatible in every way) this tiny 128x128 pixel display uses an SPI interface to communicate with a microcontroller.

Like all SPI interfaces in DisplayCore it uses the DSPI library for greater efficiency. The normal three additional digital pins are required - CS, RS and RESET.

#include <ILI9163.h>
#include <DSPI.h>

// SPI channel 0, CS = 8, RS = 9, RESET = 10
DSPI0 spi;
ILI9163 tft(spi, 8, 9, 10);
