Hi Ziggy
For the time being SPI is not really usable with LdMicro 5.3.0.1 because SPI / I2C merging is still in progress with Ihor.
I hope a new fully working version (with required libraries and docs) will come soon.
You can use SPI / I2C with my ldmicro32 for the time being:
https://github.com/joegil95/LdMicro32
Read HowTo files to make it work.
It has been tested with AtMega16 and should work as well with AtMega32. I can help if need be.
