GNSS3 click

GNSS3 click carries SIMCom’s SIM33ELA standalone GNSS module with an integrated antenna (and a connector for an external one).

Click library

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

Software Support

We provide a library for the Gnss3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Gnss3 Click driver.

Standard key functions :

  • Config Object Initialization function.

void gnss3_cfg_setup ( gnss3_cfg_t *cfg );

  • Initialization function.

GNSS3_RETVAL gnss3_init ( gnss3_t *ctx, gnss3_cfg_t *cfg );

  • Click Default Configuration function.

void gnss3_default_cfg ( gnss3_t *ctx );

Example key functions :

  • Generic parser function.

gnss3_error_t gnss3_generic_parser ( char *rsp, uint8_t command, uint8_t element, char *parser_buf );

  • Generic read function.

int32_t gnss3_generic_read ( gnss3_t *ctx, char *data_buf, uint16_t max_len );

  • Wake-up module.

void gnss3_module_wakeup ( gnss3_t *ctx );

Examples Description

This example reads and processes data from GNSS3 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gnss3_cfg_t cfg;

    //  Logger initialization.

    LOG_MAP_USB_UART( log_cfg );
    log_cfg.level = LOG_LEVEL_DEBUG;
    log_cfg.baud = 115200;
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    gnss3_cfg_setup( &cfg );
    GNSS3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gnss3_init( &gnss3, &cfg );

    gnss3_module_wakeup( &gnss3 );
    Delay_ms( 1000 );
}

Application Task

Reads the received data and parses it.

void application_task ( void )
{
    gnss3_process(  );
    parser_application( current_parser_buf );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Gnss3

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
