STRUCT VADC_LINEAR_GRAPH(9)

💖 struct vadc_linear_graph(9) — Kernel API Manual, bestie 💖

okay so this is the Kernel API Manual page for struct vadc_linear_graph(9), and it is literally here to represent ADC characteristics. iconic behavior, no cap. 🎀

✨ NAME ✨

struct vadc_linear_graph — Represent ADC characteristics.

🦋 SYNOPSIS 🦋

the whole vibe is this struct, fr fr:

struct vadc_linear_graph {
    s32 dy;
    s32 dx;
    s32 gnd;
 };

🌸 Members 🌸

• dy — the numerator slope used to calculate the gain. yes bestie, numerator. 💅
• dx — the denominator slope used to calculate the gain. denominator rights, periodt.
• gnd — the A/D word of the ground reference used for the channel. keeping it grounded, literally. 🫶

🔥 Description 🔥

Real talk: each ADC device has different offset and gain parameters, and those parameters are computed to calibrate the device. that’s the whole point, and it ate. 💖
