GPS 5 Click is a compact add-on board that provides users with positioning, navigation, and timing services. This board features the M20050-1, a compact GPS module receiver using the MediaTek MT3333 flash chip, providing a complete GNSS receiver for optimum performance from Antenova. The receiver tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou) to considerably enhance location and TTFF (Time-to-first-fix) and has configurable low power modes operating from a 3.3V power supply. In addition to the possibility of using an external antenna, backup power, and various visual indicators, the M20050-1 also has an accurate 0.5ppm TXCO ensuring short TTFF alongside multi-path algorithms, which improves position accuracy in inner-city environments.

Click library

  • Author : Stefan Filipovic
  • Date : Dec 2021.
  • Type : UART type

Software Support

We provide a library for the GPS 5 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 GPS 5 Click driver.

Standard key functions :

  • gps5_cfg_setup Config Object Initialization function.

    void gps5_cfg_setup ( gps5_cfg_t *cfg );
  • gps5_init Initialization function.

    err_t gps5_init ( gps5_t *ctx, gps5_cfg_t *cfg );

Example key functions :

  • gps5_set_rst_pin This function sets the RST pin logic state.

    void gps5_set_rst_pin ( gps5_t *ctx, uint8_t state );
  • gps5_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t gps5_generic_read ( gps5_t *ctx, char *data_buf, uint16_t max_len );
  • gps5_parse_gngga This function parses the GNGGA data from the read response buffer.

    err_t gps5_parse_gngga ( char *rsp_buf, uint8_t gngga_element, char *element_data );

Example Description

This example demonstrates the use of GPS 5 Click by reading and displaying the GPS 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. */
    gps5_cfg_t gps5_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.
    gps5_cfg_setup( &gps5_cfg );
    GPS5_MAP_MIKROBUS( gps5_cfg, MIKROBUS_1 );
    if ( UART_ERROR == gps5_init( &gps5, &gps5_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    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 )
{
    gps5_process( &gps5 );
    if ( app_buf_len > ( sizeof ( ( char * ) GPS5_RSP_GNGGA ) + GPS5_GNGGA_ELEMENT_SIZE ) ) 
    {
        gps5_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.GPS5

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.
