Functions
uint8_t	crc_check (uint8_t *buffer, uint8_t len)
	Performs a CRC (Cyclic Redundancy Check) over a buffer. More...
ssize_t	one_wire_address (uint8_t *romcode)
	Used for addressing a specific device connected to the 1-Wire bus. Usually used after a one_wire_reset() command. More...
int	one_wire_config (void)
	Initializes and configures the 1-Wire interface. More...
ssize_t	one_wire_read (uint8_t *rxbuf, uint8_t len)
	Reads from the 1-Wire bus determined number of bytes. More...
ssize_t	one_wire_read_byte (uint8_t *rxbyte)
	Reads one byte from the 1-Wire bus. More...
ssize_t	one_wire_read_rom (uint8_t *romcode)
	If there is only one device connected to the 1-Wire bus, reads its ROM code. This ROM is CRC8 checked before reporting a success. More...
ssize_t	one_wire_reset (void)
	Performs a reset on the 1-Wire bus. More...
ssize_t	one_wire_search (uint8_t *rombuf, uint8_t len)
	Performs the 1-Wire search algorithm and store ROM codes found. More...
uint8_t	one_wire_single_bit_rx (void)
	Reads 1 bit from the 1-Wire bus. More...
uint8_t	one_wire_single_bit_tx (uint8_t bit)
	Sends 1 bit over the 1-Wire bus. More...
ssize_t	one_wire_skip_rom (void)
	Used when only one device is connected to the 1-Wire bus, so sending 32-bit ROM code is unnecessary. Usually used after a one_wire_reset() command. More...
ssize_t	one_wire_write (const uint8_t *txbuf, uint8_t len)
	Sends over the 1-Wire bus a buffer with a determined length. More...
ssize_t	one_wire_write_byte (uint8_t byte)
	Sends 1 byte over the 1-Wire bus. More...
