💅 si476x_core_get_revision_info(9) — Kernel API Manual

okay so bestie, welcome to the glow-up of si476x_core_get_revision_info — yes, the header up top prints it all squished as si476x_core...evision_info(9), that's just the man page formatter doing its little truncated thing, don't panic 🫶. We're hanging out in the Kernel API Manual, which is exactly as glamorous as it sounds.

✨ NAME ✨

si476x_core_get_revision_info — and honestly, the original page just left a lil dangling dash there, so we're keeping the vibe: this is the function that goes and finds out what firmware version your device is running. Periodt.

🌸 SYNOPSIS 🌸

int si476x_core_get_revision_info (struct si476x_core *core );

That's it. One function, one pointer, zero drama. 💖

🎀 ARGUMENTS 🎀

• core — the Core device structure. that's the whole thing, that's the whole arg. she's the main character here 👑

🦋 DESCRIPTION 🦋

So what does it do? It gets the firmware version number of the device, bestie. That's the mission. No cap.

And the way it does it is a whole three-step routine — like a little ritual, honestly:

1. Power-up the device ⚡ like, wake her up, she needs to be awake for this
2. Send the 'FUNC_INFO' command 📨 the actual asking-the-question part
3. Powering the device down. 💤 and then we tuck her back in, respectfully

and here's the part you actually need to remember: the function returns zero on success and a negative error code on failure. Zero good, negative bad, that's the whole mood. 🌈
