STRUCT VADC_CHANNEL_PROP(9)

💅 struct vadc_channel_prop(9) — the Kernel API Manual glow-up ✨

okay bestie, grab your iced coffee 🍓 — this is the Kernel API Manual entry for struct vadc_channel_prop, aka the lil' glow-up sheet that tells the VADC driver everything it needs to know about one single channel. one channel. one struct. iconic behavior only. 👑

---

🌸 NAME 🌸

struct vadc_channel_prop — VADC channel property. that's it, that's the whole vibe. it's the property bag for a channel, no cap. 🎀

---

✨ SYNOPSIS ✨

struct vadc_channel_prop {
    unsigned int channel;
    enum vadc_calibration calibration;
    unsigned int decimation;
    unsigned int prescale;
    unsigned int hw_settle_time;
    unsigned int avg_samples;
    enum vadc_scale_fn_type scale_fn_type;
    const char *channel_name;
 };

like, look at her. eight fields. all main character energy. 🦋

so here's the member-by-member breakdown, and yes we're doing all of them, no skipping, i would never 💖

• channel — the channel number, bestie. go check the channel list if you need to look it up, iykyk. 🔍
• calibration — the calibration type. which flavor of calibrated are we today. 🧚
• decimation — the sampling rate supported for the channel. it's giving "how often do we sample" realness. ⭐
• prescale — channel scaling performed on the input signal. pre-game scaling, before the main event. 💅
• hw_settle_time — the time between AMUX being configured and the start of conversion. literally the little breather moment. let her settle, she's getting ready. 😭
• avg_samples — the ability to provide a single result from the ADC that is an average of multiple measurements. one result, many measurements, teamwork makes the dream work fr fr. 🌈
• scale_fn_type — Represents the scaling function to convert voltage physical units desired by the client for the channel. it's the translator between raw ADC and the voltage your client actually wants. 🔥
• channel_name — the channel name used in device tree. yes you have to match it. yes it matters. 💀

go read those too, bestie, they're right there. 🫶

lowkey a reminder that this whole thing is one struct describing ONE channel — don't go trying to cram your whole ADC in here, that's not the assignment. 🙈
