You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mac_ffd.rs
    path of file: ./repos/embassy/examples/stm32wb/src/bin
    
    the code of the file until where you have to start completion: #![no_std]

        How to make this work:

        - Obtain a NUCLEO-STM32WB55 from your preferred supplier.
        - Download and Install STM32CubeProgrammer.
        - Download stm32wb5x_FUS_fw.bin, stm32wb5x_BLE_Mac_802_15_4_fw.bin, and Release_Notes.html from
          gh:STMicroelectronics/STM32CubeWB@2234d97/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x
        - Open STM32CubeProgrammer
        - On the right-hand pane, click "firmware upgrade" to upgrade the st-link firmware.
        - Once complete, click connect to connect to the device.
        - On the left hand pane, click the RSS signal icon to open "Firmware Upgrade Services".
        - In the Release_Notes.html, find the memory address that corresponds to your device for the stm32wb5x_FUS_fw.bin file
        - Select that file, the memory address, "verify download", and then "Firmware Upgrade".
        - Once complete, in the Release_Notes.html, find the memory address that corresponds to your device for the
          stm32wb5x_BLE_Mac_802_15_4_fw.bin file. It should not be the same memory address.
        - Select that file, the memory address, "verify download", and then "Firmware Upgrade".
        - Select "Start Wireless Stack".
        - Disconnect from the device.
        - In the examples folder for stm32wb, modify the memory.x file to match your target device.
        - Run this example.

        Note: extended stack versions are not supported at this time. Do not attempt to install a stack with "extended" in the name.
