💅 pruss_cfg_gpimode — from the Kernel API Manual, bestie ✨

okay so this is pruss_cfg_gpimode, and yes the name looks like someone fell asleep on their keyboard, but I promise it's actually iconic once you get it 🫶

🌸 NAME 🌸

pruss_cfg_gpimode — set the GPI mode of the PRU 💫

✨ SYNOPSIS ✨

int pruss_cfg_gpimode (struct pruss *pruss , enum pruss_pru_id pru_id ,
enum pruss_gpi_mode mode );

🎀 ARGUMENTS 🎀

• pruss — the pruss instance handle, aka the main character of this whole operation 👑
• pru_id — the id of the PRU core within the PRUSS, like which sibling we're talking to rn 💅
• mode — the GPI mode you wanna set, this is literally the whole vibe we're assigning 🌈

🦋 DESCRIPTION 🦋

So what does it do? It sets the GPI mode for a given PRU by programming the corresponding PRUSS_CFG_GPCFGx register. That's it, that's the whole thing — no cap, it's giving "small function, big responsibility" energy 🎯

⭐ RETURN ⭐

0 on success, or an error code otherwise. slay when it's 0, and when it's not… well, at least you know 😭🔥
