weather_cfg_setup()

void weather_cfg_setup

(

weather_cfg_t *

cfg

)

Config Object Initialization function.

Parameters

cfg	Click configuration structure.

This function initializes click configuration structure to init state.

Note

All used pins will be set to unconnected state.

weather_default_cfg()

err_t weather_default_cfg

(

weather_t *

ctx

)

Click Default Configuration function.

Parameters

ctx	Click object.
