Follow the getting started instructions provided for following sensors development software tools to jump-start your evaluation or development using FRDM-STBI-A8974 sensor shield board combined with FRDM-K22F:

Configure the Hardware for Startup

4.1 Using the PCAL6524EV-ARD with an IMXRT1050 EVK Board

Check and confirm FRDM-K22F-A8974 Sensor shield board settings as described below:

To select I²C digital interface, connect pins 2-3 of SW2 on FRDM-STBI-A8974 shield board
To select SPI digital interface, connect pins 1-2 of SW2 on FRDM-STBI-A8974 shield board.
Connect pins 2-3 of SW1 to select default accelerometer operating mode i.e. "ACCEL NORMAL" mode.

Connect FRDM-K22F-A8974 Sensor shield board to FRDM-K22F MCU board using Arduino I/O headers.
Connect the sensor demonstration kit (FRDM-STBI-A8974 shield board kitted with FRDM-K22F) to the training PC via the USB cable between the OpenSDA USB port on the board and the USB connector on the PC.
For a smooth ‘out-of-box’ experience with sensor development software tools, make sure that the latest version of the default OpenSDA boot loader and firmware application is on the FRDM-K22F. This allows debugging, flash programming and serial communication over a USB cable. Obtain the latest OpenSDA drivers for FRDM boards available at OpenSDA update to the FRDM boards.
