Renesas Web Server Application Note

APPLICATION NOTE
Renesas Synergy™ Project
R30AN0244EU0103
Rev.1.03
Feb 12, 2016
NetX™ Web Server
1.
Introduction
This application note shows how to use a Synergy Software Package (SSP) Project in the Renesas Synergy™ e2 studio
to develop a simple NetX web server application.
2.
Connect to the Board
This section describes how to connect the board to power, the J-Link debugger to the PC, and to run the debug the
application to see it in action.
1.
Refer to the Quick Start Guide for PE-HMI1, DK-S7G2, or SK-S7G2 for setting up the power connection and
the J-link debugger connection from your PC to the JTAG connector on the target board.
2.
Connect an Ethernet cable to the Target board.
3.
Connect the other end of the cable to the PC through a switch, crossover cable, or straight through to the PC
using an Auto MDI-X capable port.
NOTE: For the DK-S7G2 board, set DIPSW S5 “ENET1” switch to ON, and use the Main Board Ethernet 1
port only.
3.
Import the Project into e2 studio
Refer to the "Synergy Project Import Guide" (r11an0023eu0100_synergy_ssp.pdf) for instructions on importing the
project into e2 Studio and building the project.
1.
BEFORE you build the project but after importing it, notice the static IP address of the board is specified in
“/src/demo_nx_dns_http_application.c” on the following line.
#define
SERVER_IP_ADDRESS
IP_ADDRESS(192,168,1,180)
UPDATE THE ADDRESS so it will not conflict with any other computers or devices on your network. Notice
that the IP address numbers are comma-separated.
2.
4.
Use the “Webserver Debug” configuration when debugging.
Configuring your Network
This section guides you through the process of determining the IP address that you will be using to run the web server.
There are two methods that can be used to accomplish this:
Method 1: Connecting the board to a network with a DHCP server
1.
Open a command prompt on your PC.
2.
Run command ‘ipconfig’.
3.
Look for the IP address (IPv4) of the Ethernet interface that you set using the IP_ADDRESS #define.
Method 2: Connecting the board directly to an Ethernet port on a PC with a crossover cable.
Note: Many PCs today can operate with either a regular cable or a cross over cable and will automatically detect the
kind of cable attached.
1.
Open a command prompt on your PC.
2.
Run command ‘ipconfig’.
3.
In Windows Explorer, right-click on Network and select ‘properties’.

NetXTM Web Server
4.
Click on Local Area Connection and then ‘properties’
5.
In the dialog box, highlight 'Internet Protocol version 4 (TCP/IPv4)’ and click ‘Properties’.
6.
In the window that pops up, select the radio button ‘Use the following IP address:’.
7.
Enter your IP Address. (We set it to 192.168.1.180)
8.
Set the field ‘Subnet mask:’ to ‘255.255.255.0’.
9.
Click ‘OK’ then ‘Close’.
Application Features
This section describes the features of the Next Web Server demo application and the steps needed to run the application.
If you properly configured, built, and ran your Webserver application you should see the orange light illuminated on the
board near Ethernet connector:
1.
In a command prompt window on your PC enter the command ‘ping <your IP address>. In our case it was
‘ping 192.168.1.180’. You should see something similar to this:
2.
In a web browser enter your IP address in the text field where you normally place a URL, like
www.google.com. You should see something similar to this:

General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas.
For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as
well as any technical updates that have been issued for the products.
1. Handling of Unused Pins
Handle unused pins in accordance with the directions given under Handling of Unused Pins in the
manual.
 The input pins of CMOS products are generally in the high-impedance state. In operation with
an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of
LSI, an associated shoot-through current flows internally, and malfunctions occur due to the
false recognition of the pin state as an input signal become possible. Unused pins should be
handled as described under Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of the product is undefined at the moment when power is supplied.
 The states of internal circuits in the LSI are indeterminate and the states of register settings and
pins are undefined at the moment when power is supplied.
In a finished product where the reset signal is applied to the external reset pin, the states of
pins are not guaranteed from the moment when power is supplied until the reset process is
completed.
In a similar way, the states of pins in a product that is reset by an on-chip power-on reset
function are not guaranteed from the moment when power is supplied until the power reaches
the level at which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
 The reserved addresses are provided for the possible future expansion of functions. Do not
access these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become
stable. When switching the clock signal during program execution, wait until the target clock signal
has stabilized.
 When the clock signal is generated with an external resonator (or from an external oscillator)
during a reset, ensure that the reset line is only released after full stabilization of the clock
signal. Moreover, when switching to a clock signal produced with an external resonator (or by
an external oscillator) while program execution is in progress, wait until the target clock signal is
stable.
5. Differences between Products
Before changing from one product to another, i.e. to a product with a different part number, confirm
that the change will not lead to problems.
 The characteristics of Microprocessing unit or Microcontroller unit products in the same group
but having a different part number may differ in terms of the internal memory capacity, layout
pattern, and other factors, which can affect the ranges of electrical characteristics, such as
characteristic values, operating margins, immunity to noise, and amount of radiated noise.
When changing to a product with a different part number, implement a system-evaluation test
for the given product.

7.
Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specific characteristics such as the occurrence of failure at a certain rate and
malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to guard them against the
possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to
