Macro Definition Documentation

◆ AU_DDR

#define AU_DDR DDRA

data direction register

◆ AU_ENABLE

#define AU_ENABLE PA5

enable tx pin connected to.

◆ AU_PORT

#define AU_PORT PORTA

port where the rtx modules is connected

◆ AU_TXRX

#define AU_TXRX PA6

switch tx/rx pin connected to.

◆ MAX_CMD_LENGHT

#define MAX_CMD_LENGHT 20

command's number of char

◆ MAX_SUBSTR_LENGHT

#define MAX_SUBSTR_LENGHT 10

helpfull substring max number of char

Function Documentation

◆ crc8_str()

uint8_t crc8_str ( const char * str )

return the crc8 of the string.

Parameters

str	the string

◆ htv_check_cmd()

uint8_t htv_check_cmd ( struct htv_t * htv )

check the validity of the x10str command string.

Based on the string lenght, choose which protocol to check. If cmd is not correct clear the cmd string and return FALSE else if cmd is ok, modify cmd and keep only AAAAPPC.

Returns: true: string OK, false: error

Todo:: should return errno code.

◆ htv_free()

void htv_free ( struct htv_t * htv )

free the htv struct.

Note: this should be never used.
