Finally got my Riocore Gui desktop icon working. No more cmd/cli endless keyboard input required. Just double click desktop ico, change stuff, save, generate!!
Change Exec= /to your paths/, save file on your desktop as type "Riocore Gui.desktop"

all over 1ms would be to slow because we have 1Khz servo-thread

160890 == 0.16ms
Also possible with W5500 on Mac level
No Thank You Very Much. Interesting none the less.
What we currently have is STUPID FAST and high performance already. Unless a mysterious someone has a requirement for an hypersonic motion machine-tool, nobody here (in our star system anyway) will be able to ceiling the perf of RIO as-is on any parts/processes level.
Not sure what you did but after updating the git today I'm clocking this x2 speed of what it was a few days ago. Used to be 2.5ms, now down to little more than a millisecond. Impressive stuff, Olivier.

sooo, small WARNING, I have now tidied up the boards and configs.
renamed a lot of things and removed all my test files.
if you are missing something, please let me know, i still have everything![:) :)](/media/kunena/emoticons/smile.png)
i will shortly merge the dev branch into the main and then also remove the riogui repository (everything is in the riocore)

@meister
Only when you have time (no rush), I'll need your help with a spindle encoder config. I can make the counter work (A & B signals), however I can't figure out how to make the Z index work. I've attached my config for reference, grateful if you could have a look at it and let me know what I'm doing wrong, or what I'm not doing rather.
ps. only guidance I found was in this thread, from old posts. Although all that info seems to have changed since
And so I've tried everything before begging for your help!
@cornholio
I have no idea. It's a cmd from python-venv (to activate the virtual environment that Rio is isolated into).

if you want to use the spindle in linuxcnc, the correct hal connections must be entered 'net':
{
"type": "quadencoderz",
"name": "spindle_encoder",
"pins": {
"a": {
"pin": "25",
"pull": "up"
},
"b": {
"pin": "26",
"pull": "up"
},
"z": {
"pin": "27",
"pull": "up"
}
},
"signals": {
"indexenable": {
"net": "spindle.0.index-enable",
"display": {
"type": "none"
}
},
"position": {
"net": "spindle.0.revs",
"scale": 600,
"display": {
"title": "REV"
}
},
"rps": {
"net": "spindle.0.speed-in",
"display": {
"type": "none"
}
}
}
}

Nice, thanks! Progress ha. But still not getting any index input for some strange reason. The encoder pin pulses HIGH on the oscope on each rev (probed on the FPGA pin), that works fine, but it never shows up in Lcnc. Do I need to debug this from rio.c (hal component?)if you want to use the spindle in linuxcnc, the correct hal connections must be entered 'net':

you can try
PYTHONPATH=. bin/rio-test riocore/configs/MecanixDev/config.json
-> Quadencoderz and set indexenable, then rotate the axis and look if the indexout changed
same you can do in linuxcnc -> Halshow
set rio.spindle_encoder.indexenable to 1 and look at the rio.spindle_encoder.indexout
while rotating
