Detailed Description

I2C Isolator 2 Click example.

Description

This example showcases how to initialize, configure and use the I2C Isolator 2 click module. The click provides I2C lines and power isolation for slave devices. In order for this example to work, you need the EEPROM 3 click.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the power output.

Application Task

Writes the desired message to EEPROM 3 click board and reads it back every 2 seconds. All data is being displayed on the USB UART where you can track the program flow.

Note: Make sure to provide the VCC power supply on VCC pin and EEPROM 3 click.

◆ application_init()

void application_init ( )

Logger initialization. Default baud rate: 115200 Default log level: LOG_LEVEL_DEBUG

Note: If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
