ti_bandgap_adc_to_mcelsius(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ti_bandgap_adc_to_mcelsius — bestie, let's translate raw ADC numbers into actual temperatures ✨

okay so this is a page from the Kernel API Manual, and it's about ti_bandgap_adc_to_mcelsius, which honestly does exactly what it says on the tin — it takes a raw ADC value and turns it into milli-Celsius. no cap. let's get into it 🫶

🌸 NAME 🌸

ti_bandgap_adc_to_mcelsius — converts an ADC value to mCelsius scale 💖

like, that's the whole job. glow-up for numbers.

✨ SYNOPSIS ✨

int ti_bandgap_adc_to_mcelsius (struct ti_bandgap *bgp , int adc_val ,
       int *t );

three things go in, one int comes out. the whole slay. 🎀

🦋 ARGUMENTS 🦋

  • bgp — a struct ti_bandgap pointer, i.e. the bandgap vibe itself. that's your main character. 👑
  • adc_val — the value in ADC representation. raw, unedited, pre-transformation. 🌀
  • t — the address where to write the resulting temperature in mCelsius. yes bestie, it writes through this pointer, so make sure it's a real place to put a number. 📍

💜 DESCRIPTION 💜

Simple conversion from ADC representation to mCelsius. literally it. no extra lore, no side quests.

In case the ADC value is out of the ADC conv table range, it returns -ERANGE, and 0 on success. the conversion table is indexed by the ADC values, so if adc_val goes off the end of the table, that's a hard no from the kernel. 🙈

bestie. the range check is real. if your adc_val is out of the ADC conv table range you get -ERANGE back and no cute temperature for you. 💀

🔥 RETURN 🔥

  • 0 if conversion was successful 🎉
  • else -ERANGE in case the adc_val argument is out of the ADC conv table range 😭

that's it. two outcomes. binary. iconic.
