Click library

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

Software Support

We provide a library for the G2C 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 G2C Click driver.

Standard key functions :

• Config Object Initialization function.

void g2c_cfg_setup ( g2c_cfg_t *cfg );

• Initialization function.

G2C_RETVAL g2c_init ( g2c_t *ctx, g2c_cfg_t *cfg );

Example key functions :

• Function for send command.

void g2c_send_command ( g2c_t *ctx, char *command );

• Send data reference.

void g2c_send_data_ref( g2c_t *ctx, char *reference_buf, char *data_buf );

• String parser function.

g2c_error_t g2c_actuator_str_parser ( char *rsp, char *act_ref, g2c_actuator_str_t *str_data );

Examples Description

This example reads and processes data from G2C 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;
    g2c_cfg_t cfg;

    //  Logger initialization.

    LOG_MAP_USB_UART( log_cfg );
    log_cfg.level = LOG_LEVEL_DEBUG;
    log_cfg.baud = 57600;
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    g2c_cfg_setup( &cfg );
    G2C_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    g2c_init( &g2c, &cfg );

    // Power module.

    g2c_module_power( &g2c, true, 0 );
    g2c_reset( &g2c );
    
    // Send command.

    log_printf( &logger, ">> ATE \r\n" );
    g2c_send_command( &g2c, ATE );
    Delay_ms( 3000 );
    g2c_process( );

    log_printf( &logger, ">> AT \r\n" );
    g2c_send_command( &g2c, AT );
    Delay_ms( 3000 );
    g2c_process( );

    log_printf( &logger, ">> AT_CEN \r\n" );
    g2c_send_command( &g2c, AT_CEN );
    g2c_process( );

    log_printf( &logger, ">> NETWORK \r\n" );
    g2c_send_operator_cfg( &g2c, NETWORK_USERNAME, NETWORK_PASSWORD );
    g2c_process( );

    log_printf( &logger, ">> AT NWC \r\n" );
    g2c_send_command( &g2c, AT_NWC );
    g2c_process( );

    log_printf( &logger, ">> DEVICE \r\n" );
    g2c_send_broker_cfg( &g2c, DEVICE_KEY, DEVICE_PASSWORD );
    g2c_process( );

    log_printf( &logger, ">> AT BRC \r\n" );
    g2c_send_command( &g2c, AT_BRC ); 
    g2c_process( );

    Delay_ms( 3000 );
}
  

Application Task

Reads the received data and parses it.

void application_task ( void )
{
    g2c_process( );
    actuator_demo( current_parser_buf );
    
    if ( send_data_cnt == 5 )
    {
       log_printf( &logger, ">> ACTUATOR REF \r\n" );  
       g2c_send_data_ref( &g2c, ACTUATOR_STR_REF, data_buf );
       g2c_process( );

       log_printf( &logger, ">> AT PUB \r\n" );
       g2c_send_command( &g2c, AT_PUB );
       g2c_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.G2C

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.
