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.

LCNC 2.9.5 - How to jog with a wireless xbox bt controller was created by phew
LCNC 2.9.5 - How to jog with a wireless xbox bt controller
Category: Basic Configuration
Hey,
I am trying to set up my xbox controller to jog a three axis machine (y-gantry). Using a bluetooth dongle I had to fiddle around a bit (and install xpadneo) to get the controller to connect to the system but I eventually got there and do see input when pressing buttons/moving the joysticks.
I was digging into LinuxCNC a few years ago but then life happened and I had to put the project on ice up until now. This is my first home-built CNC (wood router) and I am very new to all of this.
My goal is to be able to move the X, Y (gantry) and Z axis using the gaming controller when there is no gcode being executed.
Currently this is a parport setup and the stepper motors are not actually installed on ball screws so I do not mess up anything while testing. I am planning on switching to a mesa card in the near future.
xyyz.ini (machine basic setup)
xyyz.hal:
xbox.hal
With this setup I can see input from the controller in halshow:
However, joint.*.vel-cmd always stays 0 and obviously the stepper motors are not spinning. Also I am not sure what mode I have to use, but I also tried setting halui.mode.manual and halui.mode.teleop using the [Set] button in halshow, but this did not change anything.
Setting it up like this will not allow the machine to start when the Xbox Controller is not connected as it expects the controller to be found. The controller will shut itself off if not being used for a certain period of time and this will also result in an error popping up in axis ui.
I think my current approach is way more complicated and clumsy than it actually needs to be, but the learning curve seems to be pretty steep for me and therefore I probably resorted to using way more AI generated code than I should have.

Setting it up like this will not allow the machine to start when the Xbox Controller is not connected as it expects the controller to be found. The controller will shut itself off if not being used for a certain period of time and this will also result in an error popping up in axis ui.
I think my current approach is way more complicated and clumsy than it actually needs to be, but the learning curve seems to be pretty steep for me and therefore I probably resorted to using way more AI generated code than I should have.
How do I
- set this up correctly so the Xbox Controller input can actually controll the X, Y and Z axis?
- set this up in a way so the controller does not need to be connected in order for the machine to start and won't result in an error when the controller disconnects for some reason

I managed to get it up and running. First I disabled
However, some errors remain:I'll try to fix these - however if anybody has a quick idea what needs to be done to fix them your help is always appreciated 
Thank you so far for your quick help to get the machine up and running again!

The way covers I made recently greatly simplified the removal of chips from the table. So inspired by that success I decided to make a set of covers for the pockets at the ends of the table too.
I won't use these together with flood coolant but to make sure that any moisture that gets trapped under them still has a chance to escape I added some 2 mm holes.
