References data.

◆ refresh()

bool GaugeBQ27220::refresh ( )

inlineoverridevirtual

Refresh the battery data by reading from the registers.

This function attempts to read battery data from the specified registers of the fuel gauge. If any of the read operations fail, the function returns false; otherwise, it returns true.

Returns: true if all read operations are successful and the data is refreshed, false otherwise.

Implements GaugeBase.

◆ reset()

void GaugeBQ27220::reset ( )

inlineoverridevirtual

Reset the device.

This function sends a reset sub - command to the device to perform a reset operation.

Implements GaugeBase.

◆ setAccessKey()

void GaugeBQ27220::setAccessKey ( uint32_t key )

inline

Set the access key for the device.

If this function is not called, the default access key is 0xFFFFFFFF. This function allows the user to set a custom access key.

Parameters

key	The 32 - bit unsigned integer representing the access key to be set.

Definition at line 1052 of file gauge/ti/GaugeBQ27220.hpp.

References accessKey.

◆ setNewCapacity()

bool GaugeBQ27220::setNewCapacity	(	uint16_t	newDesignCapacity,
		uint16_t	newFullChargeCapacity
	)

inline

Set the new design capacity and full charge capacity of the battery.

This function is responsible for updating the design capacity and full charge capacity of the battery. It first checks the device's access settings, enters the configuration update mode, writes the new capacity values and checksums, and finally exits the configuration update mode. If the device was previously in a sealed state, it will be restored to the sealed mode after the operation is completed. For new devices, use the default key for access. If it is an encrypted device, use setAccessKey(uint32_t key) to set the key.

Parameters

newDesignCapacity	The new design capacity to be set, of type uint16_t.
newFullChargeCapacity	The new full charge capacity to be set, of type uint16_t.

Returns: bool Returns true if the setting is successful, false otherwise.
