What's New

Complete library rewrite with a modern, object-oriented architecture replacing the legacy static class design.

Breaking Changes

Class renamed: ads1262 → ADS1262
Instance-based API: Static class replaced with proper object instances
No more manual byte parsing: ads1262_Read_Data() (raw char*) replaced with readVoltage() and readRaw()
Pin constants: Old globals (ADS1262_DRDY_PIN, etc.) replaced with configurable constructor parameters
Register defines namespaced: Bare names (POWER, MODE0) now prefixed (ADS1262_REG_POWER, ADS1262_REG_MODE0)
SPI command defines namespaced: RREG, WREG, START, STOP → ADS1262_CMD_RREG, ADS1262_CMD_WREG, etc.
Removed SoftwareSerial dependency from examples

Flexible pin configuration — Pass custom CS, DRDY, START, and PWDN pins to the constructor, or use defaults
ESP32 support — begin(sck, miso, mosi) overload for custom SPI pin mapping on ESP32
Custom SPI instance — Pass &SPI1 or any SPIClass* for multi-SPI-bus boards
Built-in voltage conversion — readVoltage() returns volts directly with automatic gain compensation
Non-blocking reads — readRawAsync() and readVoltageAsync() return immediately if no data is ready
Continuous mode — setContinuousMode(true) enables RDATAC for high-speed streaming
Runtime reconfiguration — setDataRate(), setGain(), setReference(), and setInputMux() can be called at any time after init
Typed enumerations — ADS1262_DataRate (16 rates, 2.5–38,400 SPS), ADS1262_Gain (1x–32x), ADS1262_InputChannel (AIN0–AIN9, AINCOM, temp sensor, voltage monitors), ADS1262_Reference (internal 2.5V, external, AVDD)
Configuration struct — ADS1262_Config for passing all settings at once to begin(config)
Calibration API — performSelfCalibration(), performSystemCalibration(), setOffsetCalibration(), setGainCalibration()
Power management — powerDown(), powerUp(), reset()
Direct register access — readRegister() / writeRegister() for advanced users
Device info — readDeviceID(), testConnection(), getLibraryVersion()
Conversion helpers — countsToVoltage() and voltageToCounts()
