2.1 Main

The main routine has the following purpose:

  • Initialize basic functionality of the MSP430 MCU
  • Initialize the other MSP430FRBoot layers
  • Implement the main loop which polls the communication interface and processes commands

Figure 2-2 shows the state diagram of the main routine.
