Detailed Description

API for configuring and manipulating GNSS RTK 3 EA Click driver.

Any initialization code needed for MCU to function properly. Do not remove this line or clock might not be set correctly.

Function Documentation

gnssrtk3ea_cfg_setup()

void gnssrtk3ea_cfg_setup

(

gnssrtk3ea_cfg_t *

cfg

)

GNSS RTK 3 EA configuration object setup function.

This function initializes Click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See gnssrtk3ea_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

gnssrtk3ea_disable_device()

void gnssrtk3ea_disable_device

(

gnssrtk3ea_t *

ctx

)

GNSS RTK 3 EA disable device function.

This function disables the device by setting the CEN pin to low logic state.

Parameters

[in]

ctx

: Click context object. See gnssrtk3ea_t object definition for detailed explanation.

Returns

None.

Note

None.

gnssrtk3ea_drv_interface_sel()

void gnssrtk3ea_drv_interface_sel	(	gnssrtk3ea_cfg_t *	cfg,
		gnssrtk3ea_drv_t	drv_sel )

GNSS RTK 3 EA driver interface setup function.

This function sets a serial driver interface which will be used further in the Click driver.

Parameters

[out]	cfg	: Click configuration structure. See gnssrtk3ea_cfg_t object definition for detailed explanation.
[in]	drv_sel	: Driver interface selection. See gnssrtk3ea_drv_t object definition for detailed explanation.

Returns

Nothing.

Note

This driver selection should be called before init function to configure the driver to work with the serial interface which is consistent with the real state of the hardware. If this function is not called, the default driver interface will be set.

gnssrtk3ea_enable_device()

void gnssrtk3ea_enable_device

(

gnssrtk3ea_t *

ctx

)

GNSS RTK 3 EA enable device function.

Parameters

[in]

ctx

: Click context object. See gnssrtk3ea_t object definition for detailed explanation.

Returns

None.

Note

None.

gnssrtk3ea_generic_read()
