Member Function Documentation

◆ end()

void SY6970Core::end ( )

Deinitialize and release resources.

Called when shutting down the device. Currently a no-op but may be used for cleanup in derived implementations.

Definition at line 38 of file SY6970Core.cpp.

Referenced by PmicSY6970::end().

◆ getBusStatus()

uint8_t SY6970Core::getBusStatus ( )

Get USB port type status.

Returns the detected USB port type from REG_STATUS (0x0B). This is updated after BC1.2/HVDCP detection.

Returns

Bus state:

0: No input
1: USB SDP (Standard Downstream Port)
2: USB CDP (Charging Downstream Port)
3: USB DCP (Dedicated Charging Port)
4: HVDCP (High Voltage DCP)
5: Adapter
6: Non-standard adapter
7: OTG mode

◆ getChargeStatus()

uint8_t SY6970Core::getChargeStatus ( )

Get charging status.

Returns the current charging state from REG_STATUS (0x0B).

Returns

Charge state:

0: No charge
1: Pre-charge (weak battery)
2: Fast charge (CC/CV)
3: Charge done

◆ getDeviceRevision()

uint8_t SY6970Core::getDeviceRevision ( ) const

Get device revision.

Reads the device revision from REG_DEVICE_REV (0x14). The SY6970 returns 0x00 for the base revision.

Returns: Device revision byte (0x00 for SY6970)

Definition at line 46 of file SY6970Core.cpp.

References SensorCommWrapper::readReg().

Referenced by isValid().

◆ getFaultStatus()

bool SY6970Core::getFaultStatus ( uint8_t & fault )

Get fault status.

Reads the fault register REG_FAULT (0x0C) and returns the raw fault byte for detailed fault analysis.

Parameters

fault Reference to store fault byte

Returns: true on success, false on I2C error

Bits

Bit 7: Watchdog timeout fault
Bit 6: Boost fault
Bits 5-4: Charge fault (00: normal, 01: input fault, 10: thermal, 11: timer fault)
Bit 3: Battery fault
Bits 2-0: NTC fault
