💖 sca3000_read_av_freq(9) 💖

okay bestie, this page is straight out of the Kernel API Manual, and we are gonna read it together like the group chat is watching. no cap. 🫶

✨ NAME ✨

sca3000_read_av_freq — sysfs function to get available frequencies 💅

🦋 SYNOPSIS 🦋

ssize_t sca3000_read_av_freq (struct device *dev , struct
       device_attribute *attr , char *buf );

🌸 ARGUMENTS 🌸

• dev — Device structure for this device. the main character struct, basically 🎀
• attr — Description of the attribute. yes, that attribute ✨
• buf — Incoming string. the string coming in 🍓

💅 DESCRIPTION 💅

okay so the later modes are only relevant to the ring buffer — and they depend on the current mode. periodt.

also, the data sheet gives rather wide tolerances for these, so integer division will give a good enough answer. and ngl, not all chips have them specified at all 😭💀
