5.9.1 FFD Project Creation

Developing the Application from Scratch using MCC

  1. Create a new MCC Harmony Project. For more details, refer to Creating a New MCC Harmony Project

  2. From the “Device Resources” field, go to Harmony>Wireless>Drivers>IEEE 802.15.4>IEEE 802.15.4 MAC
    Figure 5-180. IEEE 802.15.4 MAC Component
    Note: IEEE 802.15.4 PHY and MAC components will appear in Device Resources only if, “wireless_15_4_phy” and “wireless_15_4_mac” repository is cloned in MCC framework path.
  3. Click on the plus symbol on the IEEE 802.15.4 MAC component, as illustrated in the above image.

  4. Upon selection, user will receive a prompt for auto-activation and auto-connect request of different component dependencies. Select Yes to add all the dependent components and also for all attachment auto-connect requests.

  5. Click the IEEE 802.15.4 MAC component, and open Configuration Options and
    1. In “Device Type Configuration” field, select FFD from the drop down for FFD project generation
      Note: If security required, select MAC Security Config as Enabled.
