GNSS 21 Click
GNSS 21 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description
This example demonstrates the use of GNSS 21 Click by reading and displaying the GNSS coordinates.
Example Libraries

- MikroSDK.Log
- Click.GNSS21
Example Key Functions
- gnss21_cfg_setup Config Object Initialization function.
void gnss21_cfg_setup(gnss21_cfg_t *cfg)
GNSS 21 configuration object setup function.
GNSS 21 Click configuration object.
Definition gnss21.h:199
- gnss21_init Initialization function.
struct gnss21_s gnss21_t
GNSS 21 Click context object.
err_t gnss21_init(gnss21_t *ctx, gnss21_cfg_t *cfg)
GNSS 21 initialization function.
- gnss21_generic_read This function reads a desired number of data bytes by using UART or I2C serial interface.
err_t gnss21_generic_read(gnss21_t *ctx, uint8_t *data_out, uint16_t len)
GNSS 21 data reading function.
- gnss21_parse_gga This function parses the GGA data from the read response buffer.
err_t
gnss21_parse_gga ( uint8_t *rsp_buf, uint8_t gga_element, uint8_t *element_data );
err_t gnss21_parse_gga(uint8_t *rsp_buf, uint8_t gga_element, uint8_t *element_data)
GNSS 21 parse GGA function.
- gnss21_reset_device This function resets the device by toggling the RST pin.
void gnss21_reset_device(gnss21_t *ctx)
GNSS 21 reset device function.
Application Init
Initializes the driver and logger.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
@ GNSS21_OK
Definition gnss21.h:230
#define GNSS21_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.
Definition gnss21.h:137
void application_init(void)
Definition main.c:78
Application Task
Reads the received data, parses the NMEA GGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.
{
if (
GNSS21_OK == gnss21_process( &gnss21 ) )
{
gnss21_parser_application( app_buf );
}
}
void application_task(void)
Definition main.c:108
Application Output
This Click board can be interfaced and monitored in two ways:
- Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
- UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.
Additional Notes and Information
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
