jornada_ssp_byte(9)

okay so bestie, welcome to jornada_ssp_byte(9) from the Kernel API Manual — it's the lil function that waits for the ssp bus to be ready and then sends a byte. iconic. 💅

✨ NAME ✨

jornada_ssp_byte — waits for a ready ssp bus, then sends a byte. no cap. ✨

🎀 SYNOPSIS 🎀

int jornada_ssp_byte (u8 byte );

💖 ARGUMENTS 💖

• byte — the input byte you're transmitting. that's it, that's the arg. 🫶

🦋 DESCRIPTION 🦋

okay so the tea: it waits for the fifo buffer to clear and then transmits. if the fifo buffer doesn't clear, we timeout after <timeout> rounds. ⏳

also, the mcu needs to be running before this is called — fr fr, that's a prerequisite, not a suggestion. 😭

💅 RETURN 💅

• On success: the mcu output. 💖
• On timeout: -ETIMEDOUT. 💀
