spi Pins
Set the Serial Peripheral Interface (SPI) signalling pins
pins.spiPins(DigitalPin.P0, DigitalPin.P1, DigitalPin.P2);To configure the micro:bit to write to an external device using a SPI connection, each SPI signal line is assigned to unique a pin. A SPI connection uses 3 signalling lines called MOSI, MISO, and SCK.
If you don’t set the pins for the SPI connection, the default pin assignments are used:
- P15 = MOSI, micro:bit SPI data output pin
- P14 = MISO, micro:bit SPI data input pin
- P13 = SCK, micro:bit SPI serial clock output pin
Parameters
- mosi: the pin for SPI data output, the MOSI signal pin.
- miso: the pin for SPI data input, the MISO signal pin.
- sck: the pin for SPI serial clock output, the SCK signal pin.
Example
Set the pin assignments for a SPI connection to the default pins.
pins.spiPins(DigitalPin.P15, DigitalPin.P14, DigitalPin.P13);
