✨ TRISTATE_FLOAT ✨

okay bestie, welcome to the HAL Component manual page for tristate_float 💖 this is section 9, we're in kernel-adjacent territory, and honestly? it's giving icon energy.

🌸 NAME 🌸

tristate_float — place a signal on an I/O pin only when enabled, similar to a tristate buffer in electronics.

like. literally a tristate buffer. but for HAL. no cap 💅

🎀 SYNOPSIS 🎀

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

yep that's it, that's the whole load line. count=N or names=name1[,name2...] — pick your fighter, you don't need both 🫶

🦋 FUNCTIONS 🦋

  • tristate-float.N — requires a floating-point thread. yes, a floating-point thread, don't try to sneak it into an integer one, it will not slay. If enable is TRUE, copy in to out.

so the function is just: is enable true? then do the copy. otherwise it's vibing in silence, doing absolutely nothing, and that's the whole point 🧚

🌈 PINS 🌈

  • tristate-float.N.in float in — input value. this is the thing you're passing along 💜
  • tristate-float.N.out float io — output value. this is the thing that comes out the other side (but only sometimes, see below). note the type is io, not out, so it's got main character dual energy ✨
  • tristate-float.N.enable bit in — when TRUE, copy in to out. when it's not TRUE? the output is just... not being driven by this. that's the tristate part, iykyk 👑
lowkey the whole personality of this component is that enable bit. TRUE = copy happens. anything else = hands off. periodt.

🌟 SEE ALSO 🌟

nothing listed here bestie, this page is a standalone baddie. go read the rest of the HAL docs if you want more, but this one? complete on its own 🌸

anyway that's the whole page 🎀 tristate_float is small, it's cute, it does exactly one thing and it does it flawlessly — and honestly that's the biggest slay of all 💅✨

this vibe check was brought to you by LinuxCNC Documentation, dated 2026-03-17, and the page you just read is TRISTATE_FLOAT(9). drink water, thread your floating-point stuff properly, bye bestie 🦋💜
