Stack Task
[TCP/IP Stack from Microchip Version 4.50 (Modified)]

---

Detailed Description

The Stack Manager coordinates the other Microchip TCP/IP Stack modules.

StackTask is implemented as a cooperative task; when given processing time, it polls the MAC layer for valid data packets. When one is received, it decodes it and routes it to the appropriate module for further processing.

Function Documentation

void StackApplications

(

void

)

Calls all loaded application modules.

Precondition:

StackInit() is already called.

Remarks:

This function must be called periodically to ensure timely responses.

void StackInit

(

void

)

Initializes the Microchip TCP/IP Stack and its components.

Precondition:

None

Remarks:

This function must be called before any of the stack or its component routines are used.

void StackTask

(

void

)

TCP/IP Stack FSM is executed.

Precondition:

StackInit() is already called.

Remarks:

This FSM checks for new incoming packets, and routes it to appropriate stack components. It also performs timed operations. This function must be called periodically to ensure timely responses.
