INVERT(9)

✨ INVERT 💖 (the invert(9) page, bestie edition) ✨

okay so invert is a HAL component and its whole job is: flip the number. give it a signal, get the reciprocal back. that's it, that's the girlboss 🎀

🌸 NAME 🌸

invert — Compute the inverse of the input signal

🦋 SYNOPSIS 🦋

the output is the mathematical inverse of the input, aka:

out = 1/in

and because dividing by stuff that's basically zero is lowkey a cursed idea 💀, there's a parameter called deadband that controls just how close to 0 the denominator is allowed to get before the output gets clamped to 0.

heads up bestie: deadband must be at least 1e-8, and it must be positive. no cap. 🙈

👑 FUNCTIONS 👑

• invert.N — requires a floating-point thread ⭐ (yes it literally needs one, don't come for me)

🎀 PINS 🎀

• invert.N.in float in — Analog input value 💜
• invert.N.out float out — Analog output value ✨

💅 PARAMETERS 💅

• invert.N.deadband float rw — The out will be zero if in is between -deadband and +deadband. 🫶

🌈 SEE ALSO 🌈

• invert(9)
• div2(9)
