Unbuffered MCU SAR-ADC Charge-Redistribution Kickback, Bucket-Cap & Sample-Time Solver

Deterministic Charge-conservation bucket ratio C_ext >= 2^(N+1) * C_s_adc coupled with multi-sample RC recharge droop V_err = V_in * exp(-T_period / (R_eq * C_ext)) & internal switch R_radc settling engine (.json, .csv, .c) built for STMicroelectronics, Nordic Semiconductor, Texas Instruments, Microchip — zero-upload ephemeral Wasm RAM execution.
