ms_sensors_tp_read_prom(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ms_sensors_tp_read_prom β€” from the Kernel API Manual (yes, the whole manual, we're fancy) πŸŽ€

okay bestie, sit down, hydrate, and let me tell you about a little function that's out here doing the most important job in the temperature/pressure world: reading the prom coefficients and checking the CRC. she's not flashy, but she's iconic.


✨ NAME ✨

ms_sensors_tp_read_prom β€” the prom coeff read function. that's it, that's the whole vibe. it reads prom coefficients. slay.


πŸ¦‹ SYNOPSIS πŸ¦‹

int ms_sensors_tp_read_prom(struct ms_tp_dev *dev_data);

one function, one argument, zero drama. love that for us.


🌸 ARGUMENTS 🌸

  • dev_data β€” a pointer to your temperature/pressure device data. this is the main character of the whole operation, so like… make sure it's actually pointing at something real, mkay? 🫢

πŸ’– DESCRIPTION πŸ’–

so what does she actually do? two things, and she does them well:

  1. reads the prom coefficients πŸ“–
  2. checks the CRC βœ…

and that's the tea. this function is built for the MS5637 and MS8607 chipsets β€” if you're running either of those, she's literally your girl. no cap. πŸ”₯


πŸ‘‘ RETURN πŸ‘‘

  • 0 β€” success, everything's giving flawless, we're so back πŸ’…
  • negative errno β€” something went sideways, and the negative errno is there to tell you exactly what 😭

go read all fifteen of them, bestie, i'll wait. iykyk. 🧚


πŸ’€ reminder: the dev_data pointer is the whole ballgame β€” it's your temperature/pressure device data and nothing else. no guessing, no vibes-based casting.

that's the whole page!! mwah!! πŸ“πŸ’œ
