GPS4 Click

GPS 4 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 GPS4 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Gps4

Example Key Functions

• gps4_cfg_setup Config Object Initialization function.

void gps4_cfg_setup ( gps4_cfg_t *cfg );

• gps4_init Initialization function.

err_t gps4_init ( gps4_t *ctx, gps4_cfg_t *cfg );

• gps4_generic_parser Generic parser function.

gps4_error_t gps4_generic_parser ( char *rsp,  uint8_t command, uint8_t element, char *parser_buf );

• gps4_generic_read Generic read function.

int32_t gps4_generic_read ( gps4_t *ctx, char *data_buf, uint16_t max_len );

• gps4_module_wakeup Wake-up module.

void gps4_module_wakeup ( gps4_t *ctx );

Application Init

Initializes driver and wake-up module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    gps4_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.

    gps4_cfg_setup( &cfg );
    GPS4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gps4_init( &gps4, &cfg );

    gps4_module_wakeup( &gps4 );
    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 )
{
    gps4_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.
