💖 stm32_dfsdm_start_dfsdm(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for stm32_dfsdm_start_dfsdm and honestly it's giving "small but mighty" — it does exactly one thing and it does it slayfully. let's get into it 🫶

🌸 NAME 🌸

stm32_dfsdm_start_dfsdm — start the global dfsdm interface 💅 lowkey iconic of it.

---

✨ SYNOPSIS ✨

int stm32_dfsdm_start_dfsdm (struct stm32_dfsdm *dfsdm );

like, that's the whole signature, no cap — it takes one pointer and hands you back an int 🎀

---

🦋 ARGUMENTS 🦋

• dfsdm — the handle bestie. you use it to retrieve the dfsdm context, that's literally its whole job 💜

---

🔥 DESCRIPTION 🔥

so the way this works is: it enables the interface — but only if n_active_ch is not null ✨ like, that's the vibe check. n_active_ch null? no enabling for you, periodt. not null? go off, interface, you're enabled 💅👑

fr fr, that's the whole condition — n_active_ch is the main character here 🌈

• stm32_dfsdm_stop_dfsdm(9) — the opposite energy, the "ok we're done here" sibling 💀
