GNSS4 Click

GNSS4 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.

Click Library

  • Author : MikroE Team
  • Date : apr 2020.
  • Type : UART GPS/GNSS type

Software Support

Example Description

This example reads and processes data from GNSS4 Clicks.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Gnss4

Example Key Functions

  • gnss4_cfg_setup Config Object Initialization function.
void gnss4_cfg_setup ( gnss4_cfg_t *cfg );
  • gnss4_init Initialization function.
err_t gnss4_init ( gnss4_t *ctx, gnss4_cfg_t *cfg );
  • gnss4_default_cfg Click Default Configuration function.
void gnss4_default_cfg ( gnss4_t *ctx );
  • gnss4_generic_parser Generic parser function.
gnss4_error_t gnss4_generic_parser ( char *rsp,  uint8_t command, uint8_t element, char *parser_buf );
  • gnss4_generic_read Generic read function.
uint16_t gnss4_generic_read ( gnss4_t *ctx, char *data_buf, uint16_t max_len );
  • gnss4_module_wakeup Wake-up module.
void gnss4_module_wakeup ( gnss4_t *ctx );

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gnss4_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    gnss4_cfg_setup( &cfg );
    GNSS4_MAP_MIKROBUS( cfg, MIKROBUS_POSITION_GNSS4 );
    gnss4_init( &gnss4, &cfg );

    gnss4_module_wakeup( &gnss4 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Task

Reads the received data and parses it.

void application_task ( void )
{
    gnss4_process(  );
    parser_application( current_parser_buf );
}

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.
