I2C isolator click

I2C Isolator click carries ISO1540, a low-power, bidirectional isolator compatible with I2C interfaces. On the board, the Texas Instruments chip is connected to two sets of I2C pins, one on the mikroBUS connector (SDA, SCL), the other on the upper edge of the board (SCL2, SDL2).

Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : I2C type

Software Support

We provide a library for the I2Cisolator 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 I2Cisolator Click driver.

Standard key functions :

Example key functions :

  • Generic write function.

    void i2cisolator_generic_write ( i2cisolator_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

  • Generic read function.

    void i2cisolator_generic_read ( i2cisolator_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

Examples Description

This is an example which demonstrates the use of I2C Isolator Click board.

The demo application is composed of two sections :

Application Init

Initialization driver enables - I2C, sets configuration of TMP007 sensor on IrThermo 2 click and start to write log.

void application_init ( void )
{
log_cfg_t log_cfg;
uint8_t tmp;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
I2CISOLATOR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
i2cisolator_init( &i2cisolator, &cfg );
log_printf( &logger, " Driver Initialized\r\n" );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
log_printf( &logger, " Configuration\r\n" );
log_printf( &logger, " IrThermo 2 Click\r\n" );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 100 );
}

Application Task

In this example we use IrThermo 2 click, measures the temperature with, and calculate the temperature in degrees Celsius [ C ]. Results are being sent to the USART Terminal where you can track their changes. All data logs on usb uart each second.

void application_task ( void )
{
log_printf( &logger, " Temperature : %0.2f C\r\n", temperature );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms( 1000 );
}

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.I2Cisolator

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.
