4.1 Using FRDM-K22F-A8974 Evaluation Board
- Check and confirm FRDM-K22F-A8974 Sensor shield board settings as described below:
- To select I²C digital interface, connect pins 2-3 of
SW2on FRDM-STBI-A8974 shield board - To select SPI digital interface, connect pins 1-2 of
SW2on FRDM-STBI-A8974 shield board - Connect pins 2-3 of
SW1to 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 bootloader 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
