Nano GPS Click

Nano GPS 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 Nano GPS Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Nanogps

Example Key Functions

• nanogps_cfg_setup Config Object Initialization function.

void nanogps_cfg_setup ( nanogps_cfg_t *cfg );

• nanogps_init Initialization function.

err_t nanogps_init ( nanogps_t *ctx, nanogps_cfg_t *cfg );

• nanogps_generic_parser Generic parser function.

nanogps_error_t nanogps_generic_parser ( char *rsp,  uint8_t command, uint8_t element, char *parser_buf );

• nanogps_generic_read Generic read function.

int32_t nanogps_generic_read ( nanogps_t *ctx, char *data_buf, uint16_t max_len );

• nanogps_module_wakeup Wake-up module.

void nanogps_module_wakeup ( nanogps_t *ctx );

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    nanogps_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.

    nanogps_cfg_setup( &cfg );
    NANOGPS_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    nanogps_init( &nanogps, &cfg );

    nanogps_module_wakeup( &nanogps );
}

Application Task

Reads the received data and parses it.

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

Note

Depending on the environmental conditions and the satellites availability it may take some time for the module to receive the position fix.

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.
