Click library

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

Software Support

We provide a library for the Rs4853 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 Rs4853 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void rs4853_cfg_setup ( rs4853_cfg_t *cfg );

  • Initialization function.

    RS4853_RETVAL rs4853_init ( rs4853_t ctx, rs4853_cfg_t cfg );

Example key functions :

  • Generic write function.

    void rs4853_generic_write ( rs4853_t ctx, char data_buf, uint16_t len );

  • Generic read function.

    uint16_t rs4853_generic_read ( rs4853_t ctx, char data_buf, uint16_t max_len );

  • Function ofr send command

    void rs4853_send_command ( rs4853_t ctx, char command );

Examples Description

This application is used to communicate between two RS485 clicks.

The demo application is composed of two sections :

Application Init

Initializes driver.


void application_init ( void )
{
    log_cfg_t log_cfg;
    rs4853_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.

    rs4853_cfg_setup( &cfg );
    RS4853_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    rs4853_init( &rs4853, &cfg );
}

Application Task

Reads the received data.


void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    rs4853_process( );
#endif    

#ifdef DEMO_APP_TRANSMITER
    rs4853_send_command( &rs4853, TEXT_TO_SEND );
    rs4853_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.Rs4853

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.

Thermo 28 Click is a compact add-on board that accurately measures temperature. This board features the ams AG’s AS6221, a high-accuracy digital temperature sensor. The AS6221 consists of a Si bandgap temperature factory-calibrated sensor, 16-bit ADC, and a digital signal processor, offering a high accuracy of ±0.9°C. It provides temperature data to the host controller through a compatible I2C interface, reliability, user-selectable I2C addresses, and alert functionality, which triggers an interrupt to protect the device from excessive temperatures.

Motion 4 Click

0

Motion 4 Click is a long distance PaPIR's motion sensor with plastic lense and controllable output. This Click board features EKMC1603111, a PIR motion sensor from Panasonic Corporation which can be used as human motion detector and is able to detect movement up to 12m with 170uA current consumption. Also featured on Motion 4 Click bord is TLP241A photorelay from Toshiba that is used to provide a reinforced galvanic isolation for the external signals used to drive some external high power electronic equipment when motion is detected. It's allowing up to 40V between the SSR contacts in OFF state, and currents up to 2A while in ON state, thanks to a very low ON-state resistance. Motion 4 Click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
