inv_mpu_aux_read(9)

💅 NAME 💅

inv_mpu_aux_read — the read-register function for the i2c auxiliary bus, bestie ✨

Okay so picture this: there's an i2c aux bus, right? And this little icon is the one that does the reading of registers on it. That's the whole vibe. 🎀

✨ SYNOPSIS ✨

int inv_mpu_aux_read (const struct inv_mpu6050_state *st , uint8_t addr
, uint8_t reg , uint8_t *val , size_t size );

Look at her. Five params. Main character energy, no cap. 👑

🌸 ARGUMENTS 🌸

• st — the driver's own internal state, like the driver's little diary of who it is 🫶
• addr — the chip's i2c address, aka where the chip lives on the bus 🏠
• reg — the chip register address, the exact spot inside the chip we're looking at 🔍
• val — the buffer where the read bytes get stashed 📥
• size — how many bytes we're reading, literally the count, don't skip this one 🙈

💖 DESCRIPTION 💖

Returns 0 on success, and a negative error code otherwise. That's it, that's the whole contract. If you get a negative number back, something went sideways — it's giving "not slay" 😭
