MUX16(9)

💖 MUX16(9) — HAL Component 💖

okay bestie, sit down, hydrate, because today we're talking about mux16, and honestly? it's giving selector switch energy and I'm obsessed. 🎀

✨ NAME ✨

mux16 — it picks ONE of sixteen input values for you. sixteen!! that's so many. a whole sweet sixteen of inputs. 💅

---

🌸 SYNOPSIS 🌸

loadrt mux16 [count=N|names=name1[,name2...]]

---

🦋 FUNCTIONS 🦋

• mux16.N — heads up babes, this one requires a floating-point thread. no floaty thread, no muxy. periodt.

---

👑 PINS 👑 (the main characters)

• mux16.N.use-graycode bit in — when this is set, the input uses Gray code instead of plain binary. and why would you want that, you ask? because with Gray code, every single increment changes only one select input at a time. which is chef's kiss when you're working with physical switches. no chaotic multi-bit flips, just vibes. ✨
• mux16.N.suppress-no-input bit in — this one suppresses changes to the output when all the select lines are false. it stops those annoying little jumps in the output between input transitions. 🛑 BUT — and this is important — it also makes in00 unavailable. trade-offs, bestie, we all make them.
• mux16.N.debounce-time float in — sets the debounce time in seconds. like, .10 means a tenth of a second, and the input has to stay stable for that long before the outputs change. perfect for ignoring 'noisy' switches that just will not sit still. 🙈
• mux16.N.selM bit in (M=0..3) — together, these four lil guys decide which inN value gets copied over to out. the whole squad, working as one. 🫶
• mux16.N.out-f float out
• mux16.N.out-s s32 out

these follow the value of whichever inN gets picked, based on those four sel values and whether use-graycode is active. the out-s value will be truncated and limited to the max and min values of signed values, so don't be shocked when it doesn't match out-f exactly. 😭

here's the tea on how the picking goes:

• sel3=FALSE, sel2=FALSE, sel1=FALSE, sel0=FALSE → out follows in0
• sel3=FALSE, sel2=FALSE, sel1=FALSE, sel0=TRUE → out follows in1
• etc.

yeah, etc. bestie, you know the pattern, i believe in you. 🌈

• mux16.N.inMM float in (MM=00..15) — the array of selectable outputs. sixteen of them. a whole lineup. 💀

---

🎀 PARAMETERS 🎀

• mux16.N.elapsed float r — the current value of the internal debounce timer, just for debugging. peek at it whenever. 👀
• mux16.N.selected s32 r — the current value of the internal selection variable after conversion, again, for debugging. she's showing you her work. 💖
