Your assumptions are correct for both the table and the block.

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

Category: Computers and Hardware

Hi meister,

Really cool project! I was thinking about combining FPGA support and  LinuxCNC on an  Ultra96  board (Xilinx/AMD Ultrascale device, 4x ARM64 cores and FPGA on the same chip) for years, but had no clue how the HAL messaging works. But with your UDP example as a base it was really easy! Below is a pic of the demo system, which is the Ultra96 itself, a simple self made interface board and the CNC Shield v3.0 at the top. And of course a video . :-)When I was done I saw you had added and experimental "axi" plugin and it looks like you had the same idea like me, but it did not work for me. In case you are interested, I could send my versions of the verilog and and c-code portion and maybe you could add it in a later version of your code generation magic.

Yeah, I have home and limit switches. They came with the machine, so I was able to wire them in the control board.


That's nice mate, but my reply was to the OP.
