STRUCT STM32_ADC_REGSPEC(9)

📦 version 7.3.1, in nixpkgs unstable

✨ struct stm32_adc_regspec(9) ✨

okay so this is the Kernel API Manual page for struct stm32_adc_regspec, and bestie, it's literally the master map of all the STM32 ADC registers 💅 like every offset and bitfield the driver needs, all chillin' in one struct. it's giving "table of contents but make it silicon" 🦋

🌸 NAME 🌸

struct stm32_adc_regspec — stm32 registers definition. that's it, that's the whole vibe ✨

🎀 SYNOPSIS 🎀

struct stm32_adc_regspec {
    const u32 dr;
    const struct stm32_adc_regs ier_eoc;
    const struct stm32_adc_regs ier_ovr;
    const struct stm32_adc_regs isr_eoc;
    const struct stm32_adc_regs isr_ovr;
    const struct stm32_adc_regs *sqr;
    const struct stm32_adc_regs exten;
    const struct stm32_adc_regs extsel;
    const struct stm32_adc_regs res;
    const struct stm32_adc_regs difsel;
    const u32 smpr[2];
    const struct stm32_adc_regs *smp_bits;
    const struct stm32_adc_regs or_vddcore;
    const struct stm32_adc_regs or_vddcpu;
    const struct stm32_adc_regs or_vddq_ddr;
    const struct stm32_adc_regs ccr_vbat;
    const struct stm32_adc_regs ccr_vref;
};

like look at her. seventeen members. main character energy fr fr 👑

💖 Members 💖

  • dr — data register offset. where the actual numbers land 🍓
  • ier_eoc — interrupt enable register & eocie bitfield ✨
  • ier_ovr — interrupt enable register & overrun bitfield 🔥
  • isr_eoc — interrupt status register & eoc bitfield ✨
  • isr_ovr — interrupt status register & overrun bitfield 🔥
  • sqr — reference to sequence registers array. the whole queue, love that for us 💅
  • exten — trigger control register & bitfield 🎀
  • extsel — trigger selection register & bitfield 🎀
  • res — resolution selection register & bitfield 🦋
  • difsel — differential mode selection register & bitfield 🦋
  • smpr — smpr1 & smpr2 registers offset array 📋
  • smp_bits — smpr1 & smpr2 index and bitfields 📋
  • or_vddcore — option register & vddcore bitfield 💜
  • or_vddcpu — option register & vddcpu bitfield 💜
  • or_vddq_ddr — option register & vddq_ddr bitfield 💜
  • ccr_vbat — common register & vbat bitfield 🌈
  • ccr_vref — common register & vrefint bitfield 🌈
no cap, every single one of these is const — this struct is ✨read-only✨ and she is NOT taking notes from you 🙈

and that's the page, bestie!! 🧚💖 it lives over in ./drivers/iio/adc, dated October 2026, and it's filed under struct stm32_adc_regspec(9). slay, go read the register bits, mwah 💋⭐
