2.1 Main Thread
Step 1: Initialize global variables (FmbInitInfo).
Step 2: Set the default of all devices (FmbCreatDevInfoAll) and create a thread for each
device (fmbRecvThread). This thread will receive Events sent by codec chip,
and send the message to the main thread through the pipe.
Step 3: Write firmware to the codec chip and boot codec chip (DrvBootAll).
Step 4: Read the current version of the codec chip (CheckVersionInfo).
Step 5: Set the audio compression format supported by the current version of the codec
chip (FmbCheckAudioFormatAll).
Step 6: Initialize the screen (InitScreens).
Step 7: Wait for the keyboard input and execute the commands of the codec chip setting
(OnStdinInput)
Step 8: Receive the message sent by FmbRecvThread. Determine the current state of
the codec chip and execute the corresponding actions (OnFmbMessage).
Step 9: Determine whether the device setup is completed and go to next step
(OnFmbRequestResponse).
Step 10: Repeat Step 7 ~ Step 9 .
