mt6359_auxad...mple_adc_val(9)

💖 NAME 💖

mt6359_auxadc_sample_adc_val — bestie, this one kicks off ADC channel sampling and then reads the value back out for you ✨

---

🎀 SYNOPSIS 🎀

int mt6359_auxadc_sample_adc_val (struct mt6359_auxadc *adc_dev , const
       struct iio_chan_spec *chan , u32 *out );

---

🦋 ARGUMENTS 🦋

• adc_dev — the main driver structure, like the whole vibe of the driver lives here 👑
• chan — the IIO channel spec for the ADC you're asking for, i.e. which channel you want sampled 🎯
• out — a preallocated variable where the value read from HW gets dropped, so have it ready before you call, no cap 💅

---

🌸 DESCRIPTION 🌸

Okay so here's the tea: this function starts the sampling for an ADC channel, then it waits until all of the samples are averaged (yes, all of them, it's patient like that 🧚), and then it reads the value from the HW. Slay.

⚠️ not me dropping the most important part ⚠️ — the caller must stop the ADC sampling on its own. This function never stops it. Like, ever. Not a single time. So if you forget, that's on you bestie 😭

---

⭐ RETURN ⭐

• Negative number = it's giving error 💀
• On success it returns zero and writes the read value to *out — periodt 🫶
