inv_mpu_magn_set_rate(9)

💖 NAME 💖

okay so bestie, this is inv_mpu_magn_set_rate(9), and it's here to set magnetometer sampling rate. We're in the Kernel API Manual, welcome to the group chat ✨💅.

✨ SYNOPSIS ✨

int inv_mpu_magn_set_rate (const struct inv_mpu6050_state *st , int
fifo_rate );

No cap, that's the whole signature 🫶.

🎀 ARGUMENTS 🎀

• st — driver internal state. It's the driver's own little backstage pass, lowkey essential 💖.
• fifo_rate — mpu set fifo rate. Literally the MPU's set FIFO rate, periodt 💅.

🦋 DESCRIPTION 🦋

So this function returns 0 on success, and a negative error code otherwise. That's the deal 😌.

It limits the sampling frequency to the maximum value supported by the magnetometer chip — like, it will not let the rate go feral past what the magnetometer can actually handle. The result? For higher frequencies you get duplicated data. Yep. Capped rate, duplicate data at higher frequencies, that's the vibe, iykyk 😭.

And if there's no magnetometer in the chip? It's a noop — literally does nothing in that case, no drama, no extra main-character moment 🧚🌸.
