Understanding SPI on the Raspberry Pi. Gordon writes –
I’ve been asked to include SPI (and I2C – more on that soon) support for the Raspberry Pi in mywiringPi… However because it’s hard to anticipate exactly what SPI devices you may connect up, it’s hard to provide something specific, so what I’ve done is provide some “helper” functions in a library and a guide on how to use SPI and what it’s all about…
