Nano GPS 3 click

Nano GPS 3 Click is a compact add-on board that provides fast positioning capabilities. This board features the ORG1511, a GPS/GNSS module with an integrated antenna from OriginGPS. It is a miniature, multi-channel GPS, GLONASS, Galileo, SBAS, and QZSS overlay system receiver that continuously tracks all satellites in view, providing real-time positioning data in industry-standard NMEA format. The module introduces the industry’s lowest energy per fix ratio, unparalleled accuracy, and extremely fast fixes even under challenging.

Click library

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

Software Support

We provide a library for the Nano GPS 3 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 Nano GPS 3 Click driver.

Standard key functions :

• nanogps3_cfg_setup Config Object Initialization function.

void nanogps3_cfg_setup ( nanogps3_cfg_t *cfg );

• nanogps3_init Initialization function.

err_t nanogps3_init ( nanogps3_t *ctx, nanogps3_cfg_t *cfg );

• nanogps3_default_cfg Click Default Configuration function.

void nanogps3_default_cfg ( nanogps3_t *ctx );

Example key functions :

• nanogps3_parse_gngga Nano GPS 3 parse GNGGA function.

err_t nanogps3_parse_gngga ( char *rsp,  uint8_t cmd, uint8_t element, char *element_data );

• nanogps3_generic_read Nano GPS 3 data reading function.

err_t nanogps3_generic_read ( nanogps3_t *ctx, uint8_t *data_out, uint8_t len );

• nanogps3_generic_write Nano GPS 3 data writing function.

err_t nanogps3_generic_write ( nanogps3_t *ctx, uint8_t *data_in, uint8_t len );

Example Description

This example demonstrates the use of Nano GPS 3 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. */
    nanogps3_cfg_t nanogps3_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.
    nanogps3_cfg_setup( &nanogps3_cfg );
    NANOGPS3_MAP_MIKROBUS( nanogps3_cfg, MIKROBUS_1 );
    err_t init_flag = nanogps3_init( &nanogps3, &nanogps3_cfg ); 
    if ( ( UART_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    nanogps3_default_cfg( &nanogps3 );
    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 ) 
{
    nanogps3_process( &nanogps3 );
    if ( app_buf_len > ( sizeof( NANOGPS3_RSP_GNGGA ) + NANOGPS3_NMEA_GNGGA_NUM_ELEMENT ) ) 
    {
        nanogps3_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.NanoGPS3

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.
