Click library

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

Software Support

We provide a library for the Rs485Isolator 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 Rs485Isolator Click driver.

Standard key functions :

Example key functions :

  • Set receiver state

    void rs485isolator_set_receiver_mode ( rs485isolator_t *ctx, uint8_t state );

  • Set driver state

    void rs485isolator_set_driver_mode ( rs485isolator_t *ctx, uint8_t state );

  • Function for send command.

    void rs485isolator_send_command ( rs485isolator_t *ctx, char *command );

Examples Description

This example reads and processes data from RS485 Isolator clicks.

The demo application is composed of two sections :

Application Init

Initializes driver.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 115200;
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
RS485ISOLATOR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
rs485isolator_init( &rs485isolator, &cfg );
}

Application Task

Reads the received data.

void application_task ( void )
{
#ifdef
rs485isolator_process( );
#endif
#ifdef
rs485isolator_send_command( &rs485isolator, TEXT_TO_SEND );
rs485isolator_process( );
Delay_ms( 2000 );
#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.Rs485Isolator

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.
