Function Documentation

◆ rotaryswitch_cfg_setup()

void rotaryswitch_cfg_setup ( rotaryswitch_cfg_t * cfg)

Rotary Switch configuration object setup function.

This function initializes Click configuration structure to initial values.

Parameters
[out]cfg: Click configuration structure. See rotaryswitch_cfg_t object definition for detailed explanation.
Returns
Nothing.
Note
The all used pins will be set to unconnected state.

◆ rotaryswitch_default_cfg()

err_t rotaryswitch_default_cfg ( rotaryswitch_t * ctx)

Rotary Switch default configuration function.

This function executes a default configuration of Rotary Switch Click board.

Parameters
[in]ctx: Click context object. See rotaryswitch_t object definition for detailed explanation.
Returns
  • 0 - Success,
  • -1 - Error. See #err_t definition for detailed explanation.
Note
This function can consist any necessary configuration or setting to put device into operating mode.
