💅 adxl345_fifo_transfer(9) — Kernel API Manual ✨

okay so bestie, welcome to the adxl345_fifo_transfer(9) page from the Kernel API Manual — section 9, kernel API territory, and yes we're gonna make it make sense 🫶. This one is all about reading samples number of elements. periodt 💅

🌸 NAME 🌸

adxl345_fifo_transfer — read samples number of elements. That's the whole vibe, no cap 🎀.

✨ SYNOPSIS ✨

look at this signature, she's iconic:

int adxl345_fifo_transfer (struct adxl345_state *st , int samples );

🎀 ARGUMENTS 🎀

• st — the instance of the state object of this sensor. Like, this is the sensor's state bestie, pls pass it through 🫶.
• samples — the number of lines in the FIFO referred to as fifo_entry. So yes, samples = how many FIFO lines, and the FIFO is called fifo_entry, keep that name exactly 🌸.

🦋 DESCRIPTION 🦋

okay so the recommendation here is highkey important: do a multiple-byte read of all registers to prevent a change in data between reads of sequential registers. The way to do that is to read out the data registers X0, X1, Y0, Y1, Z0, Z1 — i.e. 6 bytes at once 🔥. That's the move. Slay.

💜 RETURN 💜

Returns 0 or an error value. That's it, bestie — 0 or error value, fr fr 😭.
