Function Documentation

ambient22_cfg_setup()

void ambient22_cfg_setup

(

ambient22_cfg_t *

cfg

)

Ambient 22 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See ambient22_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.
