Arduino library for the ProtoCentral tinyGSR electrodermal-activity (GSR/EDA) breakout - absolute skin conductance in microsiemens.
Supports every tinyGSR revision from one library, selected at begin(). Drives the tinyGSR v2/v3 constant-voltage transimpedance front-end and reports ABSOLUTE skin conductance (microsiemens) and resistance, with an 8-tap smoothing filter, no-contact and over-range flags, and one-point self-calibration using the on-board Rcal resistor (JP1). Self-contained: drives the on-board 12-bit TLA2022 ADC (Lite tier) directly over I2C, no external ADC library required; an ADC-agnostic transfer-function helper supports the 16-bit ADS111x Standard tier. Qwiic / STEMMA QT. The original v1 board (LMV324 front-end, trimpot-set gain) is supported in relative ADC-count mode, replacing its dependency on the TLA20xx and FIR libraries.
