✨ si476x_core_send_command ✨

okay so bestie, welcome to the Kernel API Manual (section 9, very demure, very kernel) 💅 this is the page for si476x_core_send_command — it sends a command to si476x and waits for its response. that's literally the whole vibe. no cap. 🫶

🌸 NAME 🌸

si476x_core_send_command — sends a command to si476x and waits its response 🎀

🦋 SYNOPSIS 🦋

int si476x_core_send_command (struct si476x_core *core , const u8 command , const u8 args[] , const int argn , u8 resp[] , const int respn , const int usecs );

like, yes, that's a lot of parameters. breathe. we'll get through them together 💖

🎀 ARGUMENTS 🎀

  • core — the si476x_device structure for the device we are communicating with. it's giving "who am I even talking to" energy 🫶
  • command — the command id. which command? this one, bestie.
  • args — the command arguments we are sending 📤
  • argn — the actual size of args. don't lie about it, the kernel will know 😭
  • resp — buffer to place the expected response from the device 📥
  • respn — the actual size of resp
  • usecs — amount of time to wait before reading the response (in usecs). patience is a virtue, and also a parameter ⏳

💜 DESCRIPTION 💜

Function returns 0 on success and a negative error code on failure. that's it. that's the whole lore. ⭐

ngl, the whole thing is basically: send the command, wait a lil' (usecs, we see you), then read the response. the return value is your vibe check — 0 means slay, negative means something went sideways 💀

🔥 SEE ALSO 🔥

Kernel file ./drivers/mfd/si476x-cmd.c — and oh my god the friend group is huge, look at all of them:

main character energy, every single one of them 👑 iykyk.

okay bye bestie, go send some commands 💅✨ this lil' page came from the source tree ./drivers/mfd, dated October 2026, and it's filed under si476x_core_send_command(9) — mwah, iconic, periodt. 🍓🧚💜
