max9611_read_single(9)

🎀 NAME 🎀

okay so bestie, this is max9611_read_single(9) from the Kernel API Manual, and her whole thing is to read a single value from the ADC interface ✨ like that's the assignment and she ate 💅

🦋 SYNOPSIS 🦋

here's the exact signature, no cap:

int max9611_read_single (struct max9611_dev *max9611 , enum
max9611_conf_ids selector , u16 *raw_val );

💅 ARGUMENTS 💅

• max9611 — the max9611 device, aka the main character 🫶
• selector — the index for mux and register configuration 🔥
• raw_val — the value returned from the ADC 🎀

🔥 DESCRIPTION 🔥

so the data registers are 16 bit long, spread between two 8 bit registers with consecutive addresses — iconic little duo fr fr 💖

configure the ADC mux first, then read the register at address "reg_addr" ⭐

the smbus_read_word routine asks for 16 bits, and the ADC is kind enough to return values from "reg_addr" and "reg_addr + 1" consecutively 😭🫶

and the data are transmitted with big-endian ordering: MSB arrives first 💅 periodt.
