Click library

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

Software Support

We provide a library for the Thingstream 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 Thingstream Click driver.

Standard key functions :

• thingstream_cfg_setup Config Object Initialization function.

  void thingstream_cfg_setup ( thingstream_cfg_t *cfg ); 

• thingstream_init Initialization function.

  err_t thingstream_init ( thingstream_t *ctx, thingstream_cfg_t *cfg );

Example key functions :

• thingstream_reset_pin_state Set RST pin state.

  void thingstream_reset_pin_state ( thingstream_t *ctx, uint8_t state );

• thingstream_send_command Send command.

  void thingstream_send_command ( thingstream_t *ctx, char *command );

• thingstream_generic_parser Generic parser function.

  thingstream_error_t thingstream_generic_parser ( char *rsp,  uint8_t command, uint8_t element, char *parser_buf );

Examples Description

This example reads and processes data from Thingstream 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;
    thingstream_cfg_t cfg;

    /** 
     * 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.
    thingstream_cfg_setup( &cfg );
    THINGSTREAM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thingstream_init( &thingstream, &cfg );

    thingstream_module_power( &thingstream, true );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " --->>> INFO.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_INFO );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> CREATE.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_CREATE );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> CONNECT.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_CONNECT );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> GPS POWER.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_GPS_PWR );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> SUBSCRIBE.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_SUBSCRIBE );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> PUBLISH.. \r\n" );
    thingstream_send_command( &thingstream, THINGSTREAM_PUBLISH );
    thingstream_process( );
    log_printf( &logger, "%s", current_parser_buf );

    log_printf( &logger, " --->>> APP INIT <<<--- \r\n" );
}

Application Task

Reads the received data and parses it.

void application_task ( void )
{
    thingstream_send_command( &thingstream, THINGSTREAM_GPS_INFO );  
    thingstream_process( );
    parser_application( current_parser_buf );
} 

Note

The Click board needs to be registered with a redemption code to a Thingstream Domain. For more information please refer to the Thingstream Click user manual available on the product page.

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.Thingstream

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.
