3.2.7 Project Setup - RNWF MCC H3 Library Configuration

  1. Open the MPLAB Code Configurator from Tools>Embedded>MPLAB Code Configurator open/close
    Figure 3-60. Project Setup: MCC
  2. Select the required services from system services as illustrated below.
    Figure 3-61. System Services
  3. Add the RNWF WINCS WIFI SERVICE from Device Resources>System Service>RNWF WIFI SERVICE, in the RNWF WINCS WIFI SERVICE configuration section select the SAME54X-pro from Advanced Configurations>Host & Device Configurations>Host>SAME54X-pro, select Wi-Fi device as RNWF02 from Advanced Configurations>Host & Device Configurations>Wi-Fi device>RNWF02, select Interface mode as UART from Advanced Configurations>Host & Device Configurations>Interface mode, select the Country Code from Advanced Configurations>Country Code based on the region where product will be used, as illustrated below.
    Note:
    • The user prefers not to utilize the provided SAME54X-pro host support and wishes to configure according to a chosen host. To choose the host, the user must perform the following:
      1. Go to Advanced Configurations>Host & Device>Configurations>Host>None.
      2. Select None.
    • The user can manually add the required components and modify the system services to include host-dependent functionalities.

    1. Add all auto activated components except FreeRTOS.

      Select the required services and configurations under respective services.

  4. SERCOM Information

    1. SERCOM0 is utilized for host and RNWF02 AT command communications.
    2. SERCOM2 is used for host logs
      Note: If the user is using different SERCOM than the one preconfigured in the system services, then user must make the necessary adjustments to the SERCOM settings and update the pin configuration accordingly.

      For example, some hosts utilize FLEXCOM/SERCOM/PIC32-specific Plib. In such cases, the user must manually add the FLEXCOM/SERCOM/PIC32-specific Plib for UART in the MCC graph, along with its dependencies, including pin configuration. Additionally, the user must modify the Wi-Fi interface file of the system service to incorporate the appropriate UART Plib APIs.
