Detailed Description

API for configuring and manipulating GNSS RTK 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

◆ gnssrtk_cfg_setup()

void gnssrtk_cfg_setup ( gnssrtk_cfg_t * cfg )

GNSS RTK configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out] cfg : Click configuration structure. See gnssrtk_cfg_t object definition for detailed explanation.

Returns: Nothing.

Note: The all used pins will be set to unconnected state.

◆ gnssrtk_drv_interface_selection()

void gnssrtk_drv_interface_selection	(	gnssrtk_cfg_t *	cfg,
		gnssrtk_drv_t	drv_sel )

GNSS RTK 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 gnssrtk_cfg_t object definition for detailed explanation.
[in]	drv_sel	: Driver interface selection. See gnssrtk_drv_t object definition for detailed explanation.

Returns: Nothing.

Note: This driver selection should be call 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.

◆ gnssrtk_generic_read()

err_t gnssrtk_generic_read	(	gnssrtk_t *	ctx,
		uint8_t *	data_out,
		uint8_t	len )

GNSS RTK data reading function.

This function reads a desired number of data bytes from the module.

Parameters

[in]	ctx	: Click context object. See gnssrtk_t object definition for detailed explanation.
[out]	data_out	: Output read data.
[in]	len	: Number of bytes to be read.

Returns

>=0 - Success, or number of data bytes read in the case of UART,
-1 - Error. See #err_t definition for detailed explanation.

Note: None.

◆ gnssrtk_generic_write()

err_t gnssrtk_generic_write	(	gnssrtk_t *	ctx,
		uint8_t *	data_in,
		uint8_t	len )

GNSS RTK data writing function.

This function writes a desired number of data bytes to the module.

Parameters

[in]	ctx	: Click context object. See gnssrtk_t object definition for detailed explanation.
[in]	data_in	: Data to be written.
[in]	len	: Number of bytes to be written.

Returns

>=0 - Success, or number of data bytes written in the case of UART,
-1 - Error. See #err_t definition for detailed explanation.

Note: None.

◆ gnssrtk_get_rdy_pin()

uint8_t gnssrtk_get_rdy_pin ( gnssrtk_t * ctx )

This function initializes all necessary pins and peripherals used for this click board.

Parameters

[out]	ctx	: Click context object. See gnssrtk_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See gnssrtk_cfg_t object definition for detailed explanation.

Returns

0 - Success,
-1 - Error. See #err_t definition for detailed explanation.

Note: None.

◆ gnssrtk_parse_gngga()

err_t gnssrtk_parse_gngga	(	char *	rsp_buf,
		uint8_t	gngga_element,
		char *	element_data )

GNSS RTK parse GNGGA function.

This function parses the GNGGA data from the read response buffer.

Parameters
