💖 ucb1x00_adc_read(9) 💖

Okay bestie, this page is straight from the Kernel API Manual, and it's all about reading the specified ADC channel. Pull up a chair, we're getting into it ✨

🌸 NAME 🌸

ucb1x00_adc_read — read the specified ADC channel. That's the whole assignment, and it ate 💅

🎀 SYNOPSIS 🎀

unsigned int ucb1x00_adc_read (struct ucb1x00 *ucb , int adc_channel ,
int sync );

🦋 ARGUMENTS 🦋

  • ucb — the UCB1x00 structure describing the chip. It's giving "main character data structure" 👑
  • adc_channel — ADC channel mask. Mask on, bestie 🎭
  • sync — wait for the syncronisation pulse. Yes, that's the spelling on the page, and we respect the original's vibe 🫶

💜 DESCRIPTION 💜

So here's what happens: this function starts an ADC conversion and waits for the result. Simple enough, right? 😌

But lowkey important: synchronised ADC conversions — the ones happening via the ADCSYNC pin — must wait until the trigger is asserted and the conversion is finished. No cutting the line, no skipping the pulse, periodt ⏳✨

Right now, this function currently spins while it waits for the conversion to complete, with 2 frames max without sync. It's literally standing there refreshing the page until the conversion says "done" 😭🔥

Heads up, bestie: if it's called for a synchronised ADC conversion, it may sleep with the ADC mutex held. That's the tea — important caveat, not a drill 💀
