Click library

  • Author : MikroE Team
  • Date : Apr 2020.
  • Type : UART GPS/GNSS type

Software Support

We provide a library for the Rs4856 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 Rs4856 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void rs4856_cfg_setup ( rs4856_cfg_t *cfg );

  • Initialization function.

    RS4856_RETVAL rs4856_init ( rs4856_t ctx, rs4856_cfg_t cfg );

Example key functions :

  • Generic read function.

    uint16_t rs4856_generic_read ( rs4856_t ctx, char data_buf, uint16_t max_len );

  • Sets RE pin to high or low state

    void rs4856_re_pin_set (rs4856_t *ctx, uint8_t pin_state );

  • Sets DE pin to high or low state

    void rs4856_de_pin_set ( rs4856_t *ctx, uint8_t pin_state );

Examples Description

This example reads and processes data from RS485 6 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver.


void application_init ( void )
{
    log_cfg_t log_cfg;
    rs4856_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.

    rs4856_cfg_setup( &cfg );
    RS4856_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    rs4856_init( &rs4856, &cfg );

#ifdef DEMO_APP_RECEIVER
    rs4856_re_pin_set( &rs4856, RS4856_PIN_STATE_LOW );
    rs4856_de_pin_set( &rs4856, RS4856_PIN_STATE_LOW );
#endif

#ifdef DEMO_APP_TRANSMITER
    rs4856_re_pin_set( &rs4856, RS4856_PIN_STATE_HIGH );
    rs4856_de_pin_set( &rs4856, RS4856_PIN_STATE_HIGH );
#endif  
    log_info( &logger, " Start sending info" );  
}

Application Task

Reads the received data.


void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    rs4856_process( );
#endif    

#ifdef DEMO_APP_TRANSMITER
    rs4856_send_command( &rs4856, TEXT_TO_SEND );
    rs4856_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 ); 
#endif    
}

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.Rs4856

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.

RMS to DC click

7

RMS to DC click is a Click board that is used to convert the RMS of the input signal into a DC voltage, with a value directly readable over the I2C interface. The Click board is equipped with the LTC1968, an RMS-to-DC converter IC, which outputs an analog voltage depending on the RMS value of the input signal.
