# spi Pins
|
|
|
|
Set the Serial Peripheral Interface (SPI) signalling pins
|
|
|
|
```sig
|
|
pins.spiPins(DigitalPin.P0, DigitalPin.P1, DigitalPin.P2);
|
|
```
|
|
|
|
To configure the @boardname@ 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**.
|
|
|
|
### ~ hint
|
|
|
|
**Simulator**: This function needs real hardware to work with. It's not supported in the simulator.
|
|
|
|
### ~
|
|
|
|
If you don't set the pins for the SPI connection, the default pin assignments are used:
|
|
|
|
* **P15** = **MOSI**, @boardname@ SPI data output pin
|
|
* **P14** = **MISO**, @boardname@ SPI data input pin
|
|
* **P13** = **SCK**, @boardname@ 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.
|
|
|
|
```blocks
|
|
pins.spiPins(DigitalPin.C15, DigitalPin.C14, DigitalPin.C13);
|
|
```
