Listing - AppTaskStart shows an example of the application initialization task that should be started by the RTOS. The listing shows also what prerequisite modules that must absolutely initialized prior calling the TCP/IP function AppInit_TCPIP(), which would be responsible to initialize the Network protocol tacks. Section Sample applications will detailed the contain of the AppInit_TCPIP() function depending on the type of interface used.

(1) BSP_Init(), CPU_Init() and Mem_Init() must be called prior to the TCP-IP initialization function AppInit_TCPIP().

(2) AppInit_TCPIP() initializes the µC/TCP-IP stack and the initial parameters to configure it.

(3) If other IP applications are required this is where they are initialized.
