v0.5.2

Fix an issue for INA226 Vbus reading

v0.5.0

Standalone Direct-Read API

All Bridge classes now expose measurement methods that return raw values 'without any Serial output', enabling usage independent of the INA_monitor tool:

• readBusVoltage(), readShuntVoltage(), readCurrent(), readPower() for all chips
• readDieTemp(), readEnergy(), readCharge(), resetAccumulators() for INA228/229 family
• dataReady() polling for check for new conversion data without blocking

Multi-Channel Control (INA3221)

• enableChannel(ch, enable) / isChannelEnabled(ch): per-channel on/off
• setRshunt(ch, ohm): individual shunt resistor per channel

69 Ready-to-Flash Examples

• 28 *_basic examples (JSONL streaming for INA_monitor)
• 13 *_advanced examples (temperature, energy, charge)
• 27 *_alert_interrupt examples (hardware alert ISR)
• 1 unknown_basic (no-sensor placeholder)

Complete Documentation

• API Reference: 1500+ lines, every public method documented
• User Guide: 900+ lines, wiring, commercial modules, FAQ
• CHANGELOG:full change history

Cross-Platform

Verified on: AVR (Uno/Mega), ESP32, ESP8266, RP2040, SAMD21/51, STM32, megaAVR, Renesas ARM

Backward Compatibility

• tick() JSONL output is fully backward compatible with NiusRobotLab_INA_monitor
• beginI2c() / beginSpi() retained as legacy aliases for begin()

v0.2.5

• Add diag_serial_only USB serial diagnostic example
• Improve ESP32 I²C reliability with timeout protection
• Replace repeated-START INA reads with safer STOP + read transactions
• Report I²C probe failures as JSON ERR
• Clarify boot behavior: no samples until START
• Flush key serial ACK / INFO messages
• Expand nominal streaming rates to 1–400 Hz for I²C and 1–2000 Hz for INA229 SPI
• Use micros() timing for faster INA229 SPI streaming
• Normalize CR/LF command parsing
• Refresh docs and release metadata for v0.2.5
