Click library

  • Author : Stefan Filipovic
  • Date : Mar 2024.
  • Type : UART type

Software Support

We provide a library for the Mosaic 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 Mosaic Click driver.

Standard key functions :

  • mosaic_cfg_setup Config Object Initialization function.

    void mosaic_cfg_setup ( mosaic_cfg_t *cfg );
  • mosaic_init Initialization function.

    err_t mosaic_init ( mosaic_t *ctx, mosaic_cfg_t *cfg );

Example key functions :

  • mosaic_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t mosaic_generic_read ( mosaic_t *ctx, uint8_t *data_out, uint16_t len );
  • mosaic_enable_nmea_output This function enables the NMEA output with the selected message parameters and an output interval.

    void mosaic_enable_nmea_output ( mosaic_t *ctx, uint8_t *msg_param, uint8_t *interval );
  • mosaic_parse_gga This function parses the GGA data from the read response buffer.

    err_t mosaic_parse_gga ( uint8_t *rsp_buf, uint8_t gga_element, uint8_t *element_data );

Example Description

This example demonstrates the use of Mosaic Click by reading and displaying the GNSS coordinates.

The demo application is composed of two sections :

Application Init

Initializes the driver, reads the NMEA version, and enables the NMEA output.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    mosaic_cfg_t mosaic_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.
    mosaic_cfg_setup( &mosaic_cfg );
    MOSAIC_MAP_MIKROBUS( mosaic_cfg, MIKROBUS_1 );
    if ( UART_ERROR == mosaic_init( &mosaic, &mosaic_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( MOSAIC_OK != mosaic_wait_prompt( &mosaic ) )
    {
        log_error( &logger, " No connection prompt detected." );
        for ( ; ; );
    }
    mosaic_log_app_buf( );
    mosaic_clear_app_buf( );
    Delay_ms ( 100 );

    mosaic_send_cmd( &mosaic, MOSAIC_CMD_GET_NMEA_VERSION );
    mosaic_wait_prompt( &mosaic );
    mosaic_log_app_buf( );
    mosaic_clear_app_buf( );
    Delay_ms ( 100 );

    mosaic_enable_nmea_output( &mosaic, MOSAIC_SNO_MESSAGES_GGA, MOSAIC_SNO_INTERVAL_SEC1 );
    mosaic_wait_prompt( &mosaic );
    mosaic_log_app_buf( );
    mosaic_clear_app_buf( );
    Delay_ms ( 100 );

    log_info( &logger, " Application Task " );
}

Application Task

Reads the received data, parses the NMEA GGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.

void application_task ( void )
{
    mosaic_process( &mosaic );
    if ( app_buf_len > ( sizeof ( MOSAIC_NMEA_GGA ) + MOSAIC_GGA_ELEMENT_SIZE ) ) 
    {
        mosaic_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.Mosaic

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.

EERAM 5V Click

0

EERAM 5V Click is a static RAM (SRAM) memory Click board™ with the unique feature - it has a backup non-volatile memory array, used to store the data from the SRAM array. Since the SRAM is not able to maintain its content after the power loss, the non-volatile EEPROM backup can be a very handy addition that can be used to preserve the data, even after the power loss event. This is a very useful feature when working with critical or sensitive applications. The memory backup procedure can be executed both automatically and manually. When it is set to work in the manual mode, the onboard capacitor will act as a power source with enough power to complete the backup cycle. The power-on backup restore mode is also available, taking only about 25ms to complete.
