I2C Extend 2 Click is a compact add-on board suitable for I2C communication bus extension. This board features the PCA9615, a 2-channel multipoint differential I2C bus buffer with hot-swap logic from NXP Semiconductors. The PCA9615 converts the two default I2C signals into four differential signals, two for SCL and two for SDA.

I2C Extend 2 Click is a compact add-on board suitable for I2C communication bus extension.

The PCA9615 converts the two default I2C signals into four differential signals, two for SCL and two for SDA.
We provide a library for the I2CExtend2 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.
This library contains API for I2CExtend2 Click driver.
i2cextend2_cfg_setup
Config Object Initialization function.
void i2cextend2_cfg_setup ( i2cextend2_cfg_t *cfg );
i2cextend2_init
Initialization function.
err_t i2cextend2_init ( i2cextend2_t *ctx, i2cextend2_cfg_t *cfg );
i2cextend2_rmt_write
Generic write data in Remote Mode function.
void i2cextend2_rmt_write ( i2cextend2_t *ctx, uint8_t reg, uint8_t tx_data );
i2cextend2_rmt_read
Generic read data in Remote Mode function.
uint8_t i2cextend2_rmt_read ( i2cextend2_t *ctx, uint8_t reg );
i2cextend2_enable
Enable extend function.
void i2cextend2_enable ( i2cextend2_t *ctx, uint8_t en_extend );
This is an example which demonstrates the use of I2C Extend 2 Click board.
The demo application is composed of two sections :
Initialization driver enables - I2C, check communication with device 6DOF IMU 11 Click connected to the I2C Extend 2 Click ( Remote Mode ), set default configuration and start measurement.
void application_init ( void )

log_cfg_t log_cfg; /**< Logger config object. */

* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX

* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

In this example, we read Accel and Mag axis of the connected 6DOF IMU 11 Click boards to the I2C Extend 2 Click ( Remote Mode ) which is connected by a LAN cable to I2C Extend 2 Click ( Local Mode ). Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 2 sec.

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.
