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

Righto then, hang the expense I'll order myself a USB blaster as well. image missing /media/kunena/emoticons/smile.png

got the Panasonic encoder up and running

thanks Russell for the inspiration

but it will be a long time before it works properly.

Hmm I am usually more of a bad influence than inspiring but I'll take it haha.

That sounds awesome, are you aiming at using this for faster inputs/outputs that aren't suitable for shift registers/modbus/I2C ?

So theoretically if someone had a 6 axis closed loop to the controller milling machine the second FPGA could be used for the encoder feedback and maybe some extra IO?

yes, the advantage over shiftreg is that the evaluation of e.g. encoders is already carried out on the external fpga and only the finished values are transferred
