FWIW, since 2016 Pd-L2Ork and its K12 mode come with a comprehensive set of objects for both GPIO and SPI (MCP3008) and more recently also mechatronics externals focused on solenoids and servos (to be uploaded in the next month or so--depending how soon my student gets the commit cleaned-up). The same are also in part based on the WiringPI library.

Hi,

I wrote an external to read in values from a MCP3208 A/D converter IC
via SPI on the GPIOS of a Raspberry Pi

https://github.com/HerrSteiner/wiringPD

its based on PD-Wiring Pi by Jaime Oliver La Rosa and research on
diverse forum threads.

Cheers,

Malte
