FreeRTOS-Plus-TCP is an open source TCP/IP stack and as such is
supplied as
source files that are intended to be built as part of your RTOS
application.
It is best to start with a standard FreeRTOS
application (without the TCP/IP stack) that is known to be working correctly,
then add in the TCP/IP source files.
The application must be using the heap_4 or heap_5 memory allocator.
When you are sure the standard RTOS application is configured and
executing correctly:
-
Add the following core FreeRTOS-Plus-TCP source files into your project:
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_ARP.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_DHCP.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_DNS.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_DNS_Cache.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_DNS_Callback.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_DNS_Networking.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_DNS_Parser.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_ICMP.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_IP.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_IP_Timers.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_IP_Utils.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_Sockets.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_StreamBuffer.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_TCP_IP.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_TCP_Reception.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_TCP_State_Handling.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_TCP_Transmission.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_TCP_Utils.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_TCP_WIN.c
-
FreeRTOS-Plus/FreeRTOS-Plus-TCP/source/FreeRTOS_Tiny_TCP.c
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/FreeRTOS_UDP_IP.c
-
Add the driver for your network interface (the MAC or Ethernet driver) into your
project. Source files that implement network drivers are called NetworkInterface.c and are located in:
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/portable/NetworkInterface/[microcontroller]/
, where [microcontroller] is the family of microcontroller on which
FreeRTOS-Plus-TCP will run.
Instructions are provided for creating
network drivers for other chips.
-
Add your chosen network buffer allocation scheme
to your project. The source files that implement buffer allocation schemes are
located in:
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/portable/BufferManagement/.
At this time BufferAllocation_2.c is recommended for
simplicity because it obtains its RAM from the
FreeRTOS heap. BufferAllocation_2.c
can only be used with the heap_4 and heap_5 memory allocators.
-
Add the following core TCP/IP directories into your compiler's include path:
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/include
-
FreeRTOS-Plus/FreeRTOS_Plus_TCP/source/portable/Compiler/[compiler]
(where [compiler] is the compiler in use).
-
Any directories required to locate your chip specific driver header files.
-
Add a FreeRTOSIPConfig.h header file to your project, and ensure
the constants it contains are
configured appropriately
for your application. You can use a configuration file provided in
an example project
as a starting point.
FreeRTOSIPConfig.h tailors the core TCP/IP stack for your application. It is
application specific, not TCP/IP stack specific, and should therefore be located
in an application directory rather than a FreeRTOS-Plus-TCP directory.
