SPI library #110

Closed kriswiner closed 3 years ago

kriswiner commented 3 years ago

On the README frontpage is mentioned hardware SPI but I don;t see an SPI.h/SPI.cc library in the latest release. Is such a library necessary (I would think so)? And do you have an example of using hardware SPI with the S103F? Thanks...

Edit: I found an SPI.c file in ./test. If this works then I can figure out how to use SPI.

The SPI library is part of the core files in sduino/stm8/cores/sduino A simple #include "SPI.h" is enough to use it. And you are right, there is no proper SPI example except for the one you already found. I am open for suggestions. Is there any common SPI device that could be used for a demonstration?

PMW3901 https://www.tindie.com/products/onehorse/pmw3901-optical-flow-sensor/ is a good SPI sensor for an example. Once I get my boards from China I will give it a try.

Oh, nice sensor. But not very common, I am afraid. The most common thing I can think of are displays like the classic Nokia 5110. But they require quite complex communication before they can do anything useful - not so good for a compact example. The PCD8544 library includes some examples, but it uses bitbanged SPI instead of the real thing.

The PMW3901 is used by bitcraze in their CrazyFlie offering, and both Sparkfun and Adafruit have breakout I believe. So not too uncommon...
