Mosaic Click

Mosaic Click is a compact add-on board for precision navigation and location-based applications. This board features the Mosaic-X5, a compact global navigation satellite system (GNSS) receiver from Septentrio. The Mosaic-X5 stands out for its multi-band and multi-constellation tracking ability, ensuring robust and comprehensive global coverage. It features Septentrio's AIM+ technology for superior interference mitigation, enabling it to counteract a wide range of signal disruptions.

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 :

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;
mosaic_cfg_t mosaic_cfg;
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_wait_prompt( &mosaic );
mosaic_log_app_buf( );
mosaic_clear_app_buf( );
Delay_ms ( 100 );
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.
