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

I give up on the portable Python....toolchain. It is easy to use the IDE.

It would be good to have the IO_TYPE back in the pin list and the graphic in the Tab Overview

I do not know why, but Tab Overview shows graphic again.
IO_TYPE is better to have back, please

@meister have you done any investigation on running the iceshield on a rpi5? it seems the spi and gpio hardware is different. I am unable to get a clock signal on pin 7, it seems like it was not a well supported feature. I used an rp2040 to generate a clock signal instead, wired to pin 7, and flashed using a pi4, and have the blinking light but I'm getting EMCMOT timeouts from linuxcnc. I suspect the SPI interface is different. It's definitely there, I have the expected /dev/spidev0.1, /dev/spidev0.0 devices. I'd love to use the pi5, it's MUCH faster and has better jitter.

i have fixed the overview today.

IO_TYPE, no not at the moment, have to check some things first.

@digiex_chris
i have no RPI5, so i can not test it
i only know that there is a general problem with RPI5 and SPI,
but someone on youtube got it to work with RIO

ok, IO_TYPE for cst pins are back, but only if it is set to non-default value

ah thank you! Knowing that it's possible is helpful. I will look into it and let you know if there is something we can adjust to make it easy.
