SPHEREPROBE(9)

💖 SPHEREPROBE(9) — the HAL component that goes poking at a pretend hemisphere 💖

okay bestie, so this little cutie lives in the HAL Component section of the LinuxCNC manual, and its whole personality is: probe a pretend hemisphere. Not a real one. A vibes-only one. 🦋

✨ NAME ✨

sphereprobe — Probe a pretend hemisphere 🌸

✨ SYNOPSIS ✨

loadrt sphereprobe [count=N|names=name1[,name2...]]

That's it, that's the whole entrance. Load it up with loadrt, and you either grab count=N copies or you name your babies yourself with names=name1[,name2...]. 👑

✨ FUNCTIONS ✨

• sphereprobe.N — this is the one job it has, and it ate: it updates probe-out based on the inputs. That's the function, that's the moment, that's the main character energy. 💅

✨ PINS ✨

Every pin here comes in flavors, bb — the N is just the instance number, so if you loaded more than one you get sphereprobe.0, sphereprobe.1, and so on. 🌈

• sphereprobe.N.px s32 in, sphereprobe.N.py s32 in, sphereprobe.N.pz s32 in — this little trio is the rawcounts position, straight from a software encoder. All s32, all inputs. 🎀
• sphereprobe.N.cx s32 in, sphereprobe.N.cy s32 in, sphereprobe.N.cz s32 in — the center of the sphere, in counts. Again: s32, in. Three lil coordinates, one hypothetical sphere. 🫶
• sphereprobe.N.r s32 in — the radius of the hemisphere, in counts. s32, input, iconic. ⭐
• sphereprobe.N.probe-out bit out — and here's the payoff, bestie: a bit output. This is what all that counting was for. 😭🔥

ngl the vibe here is very much "is the point inside the imaginary bubble or not" and probe-out is the answer. No cap.
