stm32_timer_set_prescaler(9)

✨ NAME ✨

Okay so bestie, welcome to the Kernel API Manual page for stm32_timer_set_prescaler(9) — this one is all about computing and setting the prescaler register. 💅

stm32_timer_set_prescaler — Compute and set the prescaler register

🌸 SYNOPSIS 🌸

void stm32_timer_set_prescaler (struct timer_of *to );

🎀 ARGUMENTS 🎀

• to — a pointer to a timer-of structure 🫶

🦋 DESCRIPTION 🦋

So here's the vibe: depending on the timer width, this function computes the prescaler so it always targets a 10MHz timer rate for 16 bits. ✨

For 32-bit timers, they're considered precise and long enough, so they don't use the prescaler at all — no cap, they just don't need it. 💀
