stm32_adc_set_trig(9)

💅 stm32_adc_set_trig(9) 💅

okay bestie, welcome to the Kernel API Manual — today's entry is stm32_adc_set_trig(9), and she is literally here to set a regular trigger. no cap, it's giving tiny-but-important kernel API realness. 🫶

🎀 NAME 🎀

stm32_adc_set_trig — set a regular trigger. that's the assignment, and she ate. 💅

✨ SYNOPSIS ✨

int stm32_adc_set_trig (struct iio_dev *indio_dev , struct iio_trigger
*trig );

🌸 ARGUMENTS 🌸

• indio_dev — the IIO device. aka the device we're working with, main character energy. 🦋
• trig — the IIO trigger. the trigger in question, bestie. ✨

🦋 DESCRIPTION 🦋

okay so this one sets the trigger source/polarity — like SW, or HW with polarity, iykyk. here's the vibe check:

• if HW trigger is disabled — e.g. trig == NULL, conversion launched by sw — that's the disabled-HW-trigger situation. noted. 💀
• if HW trigger is enabled, she sets source & polarity. slay, periodt. 🔥
