LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

new driver plugin: TMC5160 via SPI:

I don’t really like AI, but I do give it a go every now and then.
But this time I have to admit that gpt-5.6-sol-xhigh
did a pretty good job of it; it understood how a Rio plugin is structured and also generated the Verilog code quite neatly.
So this is the first plugin I’ve created with the help of AI.
I’d had the drivers for a while, but I was always too lazy

The tricky bit here was realising that, although the drivers use SPI (for configuration), they can’t be controlled via SPI.
To do that, you have to re-solder a tiny resistor on the back – not much fun.
So if you’re going to do this, get a board with the right jumpers for SD mode and SPI mode.
