Click library

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.

Examples Description

This demo example shows RS485 communication using RS485 Isolator click.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.

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

Application Task

Depending on the selected application mode:

  • DEMO_APP_TRANSMITER - Prints "MikroE" message to UART
  • DEMO_APP_RECEIVER - Reads data from uart and prints to LOG (Default)
void application_task ( void )
{
char tmp;
// Task implementation.
#ifdef DEMO_APP_RECEIVER
// RECEIVER - UART polling
tmp = rs485isolator_generic_single_read( &rs485isolator );
log_printf( &logger, "%c", tmp );
#endif
#ifdef DEMO_APP_TRANSMITER
// TRANSMITER - TX each 2 sec
rs485isolator_generic_multi_write( &rs485isolator, demo_message, 9 );
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.

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.
