GNSS 14 Click is a compact add-on board that provides fast positioning capability to your application. This board features the MIA-M10Q, a standard precision GNSS module from u-blox. It has an exceptional sensitivity and acquisition time for all L1 GNSS signals, attributed to its integrated M10 standard precision low-power platform. The M10 platform supports concurrent reception of four GNSS (GPS, GLONASS, Galileo, and BeiDou). The high number of visible satellites enables the receiver to select the best signals. This maximizes position availability, particularly under challenging conditions like deep urban canyons.

Click library

  • Author : Nenad Filipovic
  • Date : Oct 2023.
  • Type : UART/I2C type

Software Support

We provide a library for the GNSS 14 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for GNSS 14 Click driver.

Standard key functions :

  • gnss14_cfg_setup Config Object Initialization function.

    void gnss14_cfg_setup ( gnss14_cfg_t *cfg );
  • gnss14_init Initialization function.

    err_t gnss14_init ( gnss14_t *ctx, gnss14_cfg_t *cfg );

Example key functions :

  • gnss14_parse_gngga This function parses the GNGGA data from the read response buffer.

    err_t gnss14_parse_gngga ( char *rsp_buf, uint8_t gngga_element, char *element_data );
  • gnss14_reset_device This function resets the device by toggling the RST pin.

    void gnss14_reset_device ( gnss14_t *ctx );

Example Description

This example demonstrates the use of GNSS 14 Click board by reading and displaying the GNSS coordinates.

The demo application is composed of two sections :

Application Init

Initializes the driver and resets the Click board.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    gnss14_cfg_t gnss14_cfg;  /**< Click config object. */

    /** 
     * 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.
    gnss14_cfg_setup( &gnss14_cfg );
    GNSS14_MAP_MIKROBUS( gnss14_cfg, MIKROBUS_1 );
    if ( UART_ERROR == gnss14_init( &gnss14, &gnss14_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    gnss14_reset_device( &gnss14 );
    log_info( &logger, " Application Task " );
}

Application Task

Reads the received data, parses the GNGGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.

void application_task ( void ) 
{
    if ( GNSS14_OK == gnss14_process( &gnss14 ) ) 
    {
        if ( app_buf_len > ( sizeof ( GNSS14_RSP_GNGGA ) + GNSS14_GNGGA_ELEMENT_SIZE ) ) 
        {
            gnss14_parser_application( app_buf );
        }
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.GNSS14

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
