Function Documentation

ax25_addr_t ax25_addr_init

(

char *

addr

)

Turn an ASCII encoded callsign / SSID into the 7-bit encoded and space padded 7 byte address that is used by AX.25.

Callsign and SSID should be separated by a '-' (dash)

Examples: ax25_addr_init("MYCALL") (default SSID=0) ax25_addr_init("MYCALL-1")

		ax25_addr_t *	addrs,
		uint8_t	addrs_len,
		uint8_t	ctrl,
		uint8_t	protocol
	)

void ax25_print_addr	(	char *	prefix,
		ax25_addr_t	addr
	)

Prints an AX.25 address using printf with the passed in prefix.
