Click library

• Author : MikroE Team
• Date : Jun 2020.
• Type : UART GSM/IOT type

Software Support

We provide a library for the 3g 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for 3g Click driver.

Standard key functions :

• Config Object Initialization function.

void c3g_cfg_setup ( c3g_cfg_t *cfg );

• Initialization function.

C3G_RETVAL c3g_init ( c3g_t *ctx, c3g_cfg_t *cfg );

Example key functions :

• Send Command.

void c3g_send_command ( c3g_t *ctx, char *command );

• Power up, module.

void c3g_module_power ( c3g_t *ctx, bool power_state );

• Generic read function.

uint16_t c3g_generic_read ( c3g_t *ctx, char *data_buf, uint16_t max_len );

Examples Description

This example reads and processes data from 3G clicks.

The demo application is composed of two sections :

Application Init

Initializes driver and power module.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c3g_cfg_t cfg;

    //  Logger initialization.

    LOG_MAP_USB_UART( log_cfg );
    log_cfg.level = LOG_LEVEL_DEBUG;
    log_cfg.baud = 9600;
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    c3g_cfg_setup( &cfg );
    C3G_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c3g_init( &c3g, &cfg );

    c3g_module_power( &c3g, true );

    c3g_process( );

    c3g_send_command( &c3g, AT_COMMAND );
    c3g_send_command( &c3g, AT_COMMAND );
    c3g_send_command( &c3g, AT_COMMAND );
    c3g_send_command( &c3g, ATE0_COMMAND );
    c3g_send_command( &c3g, AT_IFC_COMMAND );
    c3g_send_command( &c3g, AT_CMGF_COMMAND );
}
  

Application Task

Reads the received data.

void application_task ( void )
{
    c3g_process( );
    
    if ( send_data_cnt == 3 )
    {
       c3g_send_command( &c3g, ATH_COMMAND );
       c3g_process( );
       send_data_cnt = 0;
    }
    send_data_cnt++;
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.3g

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
