1 Hardware TCPIP stack mode
MCU User application or Microchip application library
W5200 driver files
W5200 WIZnet HW TCPIP Stack
Hardware MAC & PHY
The TWIZ5200 has two operation modes; the software TCPIP stack mode and hardware TCPIP stack mode.
The software TCPIP stack mode didn’t use the hardwired TCPIP engine but the hardware TCPIP stack mode
uses the hardwired TCPIP engine, so we don’t need Microchip software TCPIP stack because the W5200
already has hardware TCPIP stack (worldwide patent). So user can save the memory and MCU resource
using this mode. WIZnet supports driver files to use the Microchip Application Library as usual.
*Note: hardware TCPIP stack v1.1 supports SSL only one socket now. So you cannot use more than 2
sockets for SSL simultaneously.
Below table is example project environment.

2 Quick Start with W5200 Ethernet PICtailTM
2.1 Step1; Copy the necessary files
Plus
The locations (directory path) of W5200 driver files and other necessary files for HW TCPIP library are,
Microchip Solutions\ TCPIP\ Demo App\ Configs\ HWP EX16_W5200_Cxx.h
TCPIP W5200.h
Cxx-xxx_W5200.mcp
Cxx-xxx_W5200.mcw
HardwareProfile.h
TCPIPConfig.h
Microchip\ Include\ TCPIP Stack\ W5200.h
MAC.h
TCP_W5200.h

UDP_W5200.h
TCPIP.h
TCPIP Stack\ W5200.c
TCP_W5200.c
UDP_W5200.c
IP.c
ARP.c
ICMP.c
Each files must be copied to exact directory before using the W5200 Ethernet PICtail™(Plus) board.
Especially the MAC.h , HardwareProfile.h and TCPIPConfig.h files may already placed specified
directory so you should overwrite it. The TCP_W5200.c/h files substitute TCP.c/h and UDP_W5200.c/h files
substitute UDP.c/h to use hardware TCPIP stack.
File Name Descriptions
HWP xxx_W5200_Cxx.h Defines I/O including SPI to use W5200 and your board
TCPIP W5200.h Defines network settings and others for applications
Cxx-xxx_W5200.mcp MPLAB project file for xxx board
Cxx-xxx_W5200.mcw MPLAB workspace file xxx board
HardwareProfile.h Defines file link for “HWP EX16_W5200_C30.h”
TCPIPConfig.h Defines file link for “TCPIP W5200.h”
W5200.h Defines registers and address for W5200
MAC.h Defines memory map, size and others for W5200
TCP_W5200.h Header file for TCP_W5200.c
UDP_W5200.h Header file for UDP_W5200.c
TCPIP.h Includes modified header file TCP_W5200.h and UDP_W5200.h
W5200.c W5200 driver file for hardware TCPIP stack
TCP_W5200.c Hardware TCP driver file
UDP_W5200.c Hardware UDP driver file
IP.c, ARP.c, ICMP.c Empty functions because the W5200 has IP, ARP and ICMP HW logic
2.2 Step2; Open the project file and use as usual
After copying these files, open the project file using the MPLAB IDE and use the Microchip Application
Libraries as usual.

2.3 Step3; Make a new project (Optional)
If you don’t use attachded project file, you can make your own new project, the easiest way is modifying
existing project. For example using Explorer 16 board, open the C30-EX16_ENC28.mcp project file and
replace or add driver files (W5200.c/h, TCP_W5200.c/h, UDP_W5200.c/h, HWP EX16_W5200_C30.h, TCPIP
W5200.h, MAC.h, HardwareProfile.h, TCPIPConfig.h) files above. Then define the Preprocessor Macros
‘CFG_INCLUDE_EX16_W5200’ in the build options.
1. Add W5200.c and W5200.h files to the project
2. Delete TCP.c/h, UDP.c/h and add the TCP_W5200.c/h, UDP_W5200.c/h.

3. Delete HWP EX16_ENC28_C30.h to and add HWP EX16_W5200_C30.h, also delete TCPIP ENC28.h and
add TCPIP W5200.h. Then replace MAC.h file.
4. Remove the Preprocessor Macros ‘CFG_INCLUDE_EX16_ENC28’ and add new Preprocessor Macros
‘CFG_INCLUDE_EX16_W5200’.

Then set the library and including path. And configure other settings (memory model, optimization level and
others) properly. MAC.h, HardwareProfile.h, TCPIPConfig.h files are must be replaced with modified file ( as
in the step 2).
3 TCPIP Stack and App. Configuration; TCPIP W5200.h In the hardware TCPIP stack mode, we cannot use the “TCPIP Configuration Wizard” because it is only
available for software TCPIP stack mode. So we should modify the TCPIP W5200.h file directly.
Don’t use this tool under the HW TCPIP stack mode!!

3.1 Step 1; Select Application
User can select the application what they want to run with HW TCPIP stack. Open the TCPIP W5200.h and
uncomment the definition. For example, if you want HTTP server and telnet server, just uncomment the
definition line.
#define STACK_USE_HTTP2_SERVER
#define STACK_USE_TELNET_SERVER
Note: The SSL protocol (Server or Client) can support only one socket with HW TCPIP stack version
1.1 now.
3.2 Step 2; Make TCPSockInitializer (Only for TCP App.)
After step 1, we must make TCPSocketInitializer if we use TCP application. The structure of
TCPSocketInitializer is as below,
{Socket Purpose, Memory Medium, TX memory size, RX memory size }
Under the HW TCPIP stack version, the “Memory Medium and TX/RX memory size” are already fixed because
of the W5200. So the TCPSocketInitializer example for HTTP server is,
{TCP_PURPOSE_HTTP_SERVER, TCP_ETH_RAM, W5200_TX_RAM_SIZE, W5200_RX_RAM_SIZE}
And the TCPSocketInitializer example for telnet server is,
{TCP_PURPOSE_TELNET, TCP_ETH_RAM, W5200_TX_RAM_SIZE, W5200_RX_RAM_SIZE}
For more detail information, please refer to the TCPIP W5200.h file.
The UDP application doesn’t need above definition.
Note: the W5200 has 8 HW sockets, so user cannot use more than 8 sockets simultaneously. I f you
assign 5 sockets for TCP, other 3 sockets are automatically assigned for UDP.
