RS232 Isolator Click

RS232 Isolator Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

This example reads and processes data from RS232 Isolator Clicks.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Rs232Isolator

Example Key Functions

  • rs232isolator_cfg_setup Config Object Initialization function.
void rs232isolator_cfg_setup ( rs232isolator_cfg_t *cfg );
  • rs232isolator_init Initialization function.
err_t rs232isolator_init ( rs232isolator_t *ctx, rs232isolator_cfg_t *cfg );
  • rs232_2_set_rts Function settings RTS state.
void rs232_2_set_rts ( rs232isolator_t *ctx, uint8_t state );
  • rs232_2_get_cts Read CTS state.
uint8_t rs232_2_get_cts ( rs232isolator_t *ctx );
  • rs232isolator_send_command Function for send command.
void rs232isolator_send_command ( rs232isolator_t *ctx, char *command );

Application Init

Initializes driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    rs232isolator_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.

    rs232isolator_cfg_setup( &cfg );
    RS232ISOLATOR_MAP_MIKROBUS( cfg, MIKROBUS_POSITION_RS232ISOLATOR );
    rs232isolator_init( &rs232isolator, &cfg );
}

Application Task

Reads the received data.

void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    rs232isolator_process( );
#endif
    
#ifdef DEMO_APP_TRANSMITER
    rs232isolator_send_command( &rs232isolator, TEXT_TO_SEND );
    rs232isolator_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
#endif    
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
