Hardware requirements

  • Micro USB cable

  • EVK-MIMXRT595 board

  • Personal Computer

Board settings

The flexio_i2c_interrupt example is requires connecting the FLEXIO pins with the I2C pins The connection should be set as following:

Pin Name        Board Location  CONNECTS TO  Pin Name   Board Location
FLEXIO_I2C_SCL  J27-1              	     I2C_SCL    J28-10
FLEXIO_I2C_SDA  J27-2            	     I2C_SDA    J28-9

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the OpenSDA USB port on the board.

  2. Open a serial terminal on PC for OpenSDA serial device with these settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the demo runs successfully, the log would be seen on the OpenSDA terminal like:
