Member Enumeration Documentation

◆ MemoryBank

enum HID::MemoryBank

Possible memory banks to select.

Enumerator
MEMBANK_NONE	No bank selected.
MEMBANK_CODEPLUG_LOWER	Lower memory bank (EEPROM).
MEMBANK_CODEPLUG_UPPER	Upper memory bank (FLASH).
MEMBANK_CALLSIGN_LOWER	Callsign DB memory lower bank (also FLASH).
MEMBANK_CALLSIGN_UPPER	Callsign DB memory upper bank (also FLASH).

Member Function Documentation

◆ read()

bool HID::read	(	uint32_t	bank,
		uint32_t	addr,
		unsigned char *	data,
		int	nbytes
	)

Reads a block of data from the device at the given block number.

Parameters

bank	The memory bank to read from.
addr	The address to read from within the memory bank.
data	Pointer to memory where the read data is stored.
nbytes	The number of bytes to read.

Returns: true on success.

◆ read_finish()

bool HID::read_finish ( )

virtual

This function ends a series of read operations.

This function will be re-implemented by certain interfaces that need completion of read operations (e.g., HID).

Implements RadioInterface.

◆ read_start()

bool HID::read_start	(	uint32_t	bank,
		uint32_t	addr
	)

virtual

Starts the read process from the specified bank and at the given address.

Parameters

bank	Specifies the memory bank to read from. Usually there is only one bank. Some radios, however, to have several memory banks to hold the codeplug. For example the Open GD77 has EEPROM and Flash memory banks with independent addresses.
addr	Specifies the address to read from.

Implements RadioInterface.

◆ write()

bool HID::write	(	uint32_t	bank,
		uint32_t	addr,
		unsigned char *	data,
		int	nbytes
	)

Writes a block of data to the device at the given block number.

Parameters

bank	The memory bank to read from.
addr	The address to read from within the memory bank.
data	Pointer to memory where the read data is stored.
nbytes	The number of bytes to read.

Returns: true on success.

◆ write_finish()

bool HID::write_finish ( )

virtual

This function ends a series of write operations.

This function will be implemented by certain interfaces that need completion of write operations (e.g., HID).

Implements RadioInterface.

◆ write_start()

bool HID::write_start	(	uint32_t	bank,
		uint32_t	addr
	)

virtual

Starts the write process into the specified bank and at the given address.

Parameters

bank	Specifies the memory bank to write to. Usually there is only one bank. Some radios, however, to have several memory banks to hold the codeplug. For example the Open GD77 has EEPROM and Flash memory banks with independent addresses.
addr	Specifies the address to write to.

Implements RadioInterface.
