Software Support

We provide a library for the I2C Isolator 5 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for I2C Isolator 5 Click driver.

Example Description

This library contains API for the I2C Isolator 5 click driver.

This demo application shows an example of an I2C Isolator 5 click wired to the VAV Press click for reading differential pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART.

After driver initialization and default settings, the app set VAV Press click I2C slave address ( 0x5C ) and enable device.

void application_init ( void )
{
log_cfg_t log_cfg;
i2cisolator5_cfg_t i2cisolator5_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
i2cisolator5_cfg_setup( &i2cisolator5_cfg );
I2CISOLATOR5_MAP_MIKROBUS( i2cisolator5_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == i2cisolator5_init( &i2cisolator5, &i2cisolator5_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, " Set VAV Press Click I2C Slave Address \r\n" );
Delay_ms( 100 );
log_info( &logger, " Application Task " );
}

Application Task

This is an example that shows the use of an I2C Isolator 5 click boardâ„¢.

Logs pressure difference [ Pa ] and temperature [ degree Celsius ] values of the VAV Press click written to the I2C Isolator 5 click boardâ„¢.
Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
{
log_printf( &logger, " Diff. Pressure : %.4f Pa \r\n", diff_press );
log_printf( &logger, " Temperature : %.2f C \r\n", temperature );
log_printf( &logger, "--------------------------------\r\n" );
}
Delay_ms( 2000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.I2CIsolator5

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. UART terminal is available in all MikroElektronika compilers.
