//! SPI loopback test

//! Folowing pins are used:
//! SCLK GPIO6
//! MISO GPIO2
//! MOSI GPIO7
//! CS GPIO10
//! SCLK GPIO6
//! SDI GPIO2
//! SDO GPIO7
//! CS GPIO10
//!
//! Depending on your target and the board you are using you have to change the pins.
//!
//! This example transfers data via SPI.
//! Connect MISO and MOSI pins to see the outgoing data is read as incoming data.
//! Connect SDI and SDO pins to see the outgoing data is read as incoming data.
