STRUCT STM32_ADC_INFO(9)

📦 version 7.3.1, in nixpkgs unstable

👑 struct stm32_adc_info(9) 👑

okay so bestie, we're in the Kernel API Manual today and this page is literally about struct stm32_adc_info — the per-instance config data for the stm32 ADC. yeah. that one. it's giving "small struct, big responsibilities" and I'm obsessed 💅

✨ NAME ✨

struct stm32_adc_info — stm32 ADC, per instance config data

like, per instance. each ADC gets its own little info blob and it holds everything the driver needs to know about that specific one 🎀

🌸 SYNOPSIS 🌸

struct stm32_adc_info {
    int max_channels;
    const unsigned int *resolutions;
    const unsigned int *oversampling;
    const unsigned int num_res;
    const unsigned int num_ovs;
 };

that's the whole struct fr fr — five members, no drama, no cap 🫶

🦋 Members 🦋

  • max_channels — Number of channels. that's it, that's the count 💖
  • resolutions — available resolutions. not a single number, a whole list of them, so go read the array, don't just assume one ✨
  • oversampling — available oversampling ratios. yes king, plural, it's an array too 🔥
  • num_res — number of available resolutions. the length of the resolutions list, so you know how far to walk it 👑
  • num_ovs — number of available oversampling ratios. same deal, the count for oversampling 💅
lowkey important: resolutions and oversampling are const unsigned int * while the counts are const unsigned int — pointers plus their lengths, classic group-chat pairing, you never send one without the other 🧚
