🎀 stm32f4_i2c_xfer_msg(9) 🎀

okay so this page comes from the Kernel API Manual, and it's all about transferring one single I2C message — no cap, one message. Let's go, bestie 💅✨

🌸 NAME 🌸

stm32f4_i2c_xfer_msg — Transfer a single I2C message

✨ SYNOPSIS ✨

int stm32f4_i2c_xfer_msg (struct stm32f4_i2c_dev *i2c_dev , struct
       i2c_msg *msg , bool is_first , bool is_last );

💖 ARGUMENTS 💖

Okay, here's the cast:

• i2c_dev — Controller's private data. It's the controller's own little data stash, iykyk.
• msg — I2C message to transfer. The message that's getting transferred, periodt.
• is_first — first message of the sequence. It's literally the first one in the sequence, bestie.
• is_last — last message of the sequence. The final one in the sequence. The way that closure hits 🫶
