Referenced by e_light_get_config().

#define SENSOR_LIGHT_CONFIG_FILE   "A:/CFG/LIGHT.TXT"

Path to the config file.

Referenced by b_light_init(), and e_light_set_config().

bool b_light_get_value

(

xLogDef *

pxLog

)

Get the current light value.

Get the current light sensor value.

Parameters

pxLog

eExecStatus e_light_get_config

(

signed portCHAR **

ppcStringReply

)

Get the light sensor config.

Parameters

ppcStringReply

	)

Set the sensor config.

Parameters

ppcStringReply	Input/Output. The response string. NEVER NULL AS INPUT.
ac	Input. Number of args
av	Input. pointer to args

Returns

the status of the command execution.
