Syntax: i32 getRemoteSwitch(u8 *val)
Description: The function gets the status of the Remote Switch.
Parameters: This function takes a pointer to an unsigned char variable
as the parameter. After calling this function, the status
of the Remote Switch will be put at the memory which is
pointed by the parameter ‘val’. If the Remote Switch is
enabled, ‘*val’ is 0x5A. If the Remote Switch is disabled,
the ‘*val’ is 0xA5. Users can use the macros ‘ENABLED’
(0x5A) and ‘DISABLED’(0xA5) to test the status value
‘*val’.
For example:
u8 val;
i32 result;
result = getRemoteSwitch(&val);
if(result == 0) {
if(val == ENABLED)
printf(“Remote Switch is enabled.\n”);
else if( val == DISABLED )
printf(“Remote Switch is disabled.\
n”);
}
Return Value: If this function works successfully, it returns 0, any other
value stands for error.
