💖 SIM_SPINDLE(9) 💖

okay bestie, welcome to sim_spindle — it's a HAL component, and it's literally a fake spindle with an index pulse. pretend spindle. simulated. it goes round and round and tells you where it is. iconic behavior honestly 🌸

✨ NAME ✨

sim_spindle — a simulated spindle with an index pulse 🌀

🌈 SYNOPSIS 🌈

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

like, you loadrt her, and then you either say how many you want (count=N) or you name them yourself (names=name1[,name2...]). pick your fighter 💅

🎀 FUNCTIONS 🎀

  • sim-spindle.N — she needs a floating-point thread, no cap. that's not optional, she's not doing the integer-thread thing. 💀

👑 PINS 👑

  • sim-spindle.N.velocity-cmd float in — the commanded speed. you tell her how fast, that's the vibe. 🔥
  • sim-spindle.N.position-fb float out — feedback position, and it's in revolutions. that's the whole point, she's reporting back 🫶
  • sim-spindle.N.index-enable bit io — set this and at the next full rotation, position-fb gets reset to 0. reset era. ✨

🦋 PARAMETERS 🦋

  • sim-spindle.N.scale float rw (default: 1.0) — the factor that gets applied to velocity-cmd.

so the result of velocity-cmd * scale needs to come out in revolutions per second. for example, if your velocity-cmd is in revolutions/minute, then scale should be set to 1/60 or 0.016666667. do the math bestie, she's not doing it for you 😭

lowkey reminder: sim-spindle.N really does require a floating-point thread. don't come for me when it doesn't run. 🙈
