Click library

Software Support

We provide a library for the CanIsolator 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 CanIsolator Click driver.

Standard key functions :

Examples Description

This is a example which demonstrates the use of Can Isolator Click board.

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_printf( &logger, "---- Application Init ----\r\n" );
// Click initialization.
CANISOLATOR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
canisolator_init( &canisolator, &cfg );
log_printf( &logger, "---------------------\r\n" );
log_printf( &logger, " CAN Isolator Click\r\n" );
log_printf( &logger, "---------------------\r\n" );
Delay_ms( 100 );
}

Application Task

Checks if new data byte has received in RX buffer ( ready for reading ) and if ready than reads one byte from RX buffer. In the second case, the application task writes message data via UART. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
canisolator_data_t tmp;
// Task implementation.
#ifdef DEMO_APP_RECEIVER
// RECEIVER - UART polling
tmp = canisolator_generic_single_read( &canisolator );
log_printf( &logger, " %c ", tmp );
#endif
#ifdef DEMO_APP_TRANSMITER
// TRANSMITER - TX each 2 sec
uint8_t cnt;
for ( cnt = 0; cnt < 9; cnt ++ )
{
canisolator_generic_single_write( &canisolator, demo_message[ cnt ] );
Delay_ms( 100 );
}
Delay_ms( 2000 );
#endif
}

Note

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.
