✨ NAME ✨

spindle_monitor — spindle at-speed and underspeed detection 🌀

Like, it literally watches your spindle and tells you if it's spinning fast enough. It's giving hall monitor but for RPMs. Iconic.

Look at that. Textual look of pure loadrt. You're doing great. 🫶

🦋 FUNCTIONS 🦋

• spindle-monitor.N — and heads up, this one requires a floating-point thread. Not optional, not negotiable, the float thread is the moment. no cap.

---

🎀 PINS 🎀

• spindle-monitor.N.spindle-is-on bit in — input bit telling us whether the spindle is on at all. vibe check: is it on? 👀
• spindle-monitor.N.spindle-command float in — the commanded spindle value coming in.
• spindle-monitor.N.spindle-feedback float in — the actual feedback value coming in. this is the real tea ☕
• spindle-monitor.N.spindle-at-speed bit out — output saying yeah, we're at speed, slay ✨
• spindle-monitor.N.spindle-underspeed bit out — output saying nope, we're underspeed. sad girl hours 😭

---

💅 PARAMETERS 💅

• spindle-monitor.N.level u32 rw — the state machine state. read/write, so you can poke at it if you're nosy. lowkey it's the internal mood tracker of the component.
• spindle-monitor.N.threshold float rw — the threshold. read/write, so tune it to your heart's content 💖
