Detailed Description

I2C Isolator 5 Click 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.

Application Task

This is an example that shows the use of an I2C Isolator 5 click board™. Logs pressure difference [ Pa ] and temperature [ degree Celsius ] values of the VAV Press click written to the I2C Isolator 5 click board™.
Results are being sent to the Usart Terminal where you can track their changes.

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.
