4.1 Using FRDM-K22F-A8974 Evaluation Board

  1. 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
  2. Connect FRDM-K22F-A8974 Sensor shield board to FRDM-K22F MCU board using Arduino I/O headers
  3. 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
  4. 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
