Getting Started with default application

This chapter describes How to start working with this demo application, but it's well documented in the “Charon 2 DB demo” page.

The Development Board contains frequently used peripherals: Ethernet connection (10Mbit twisted pair), LCD display connector, RS232 line, thermometer(s) connection, LED diodes as outputs, DIP switches as inputs, I/O pins on connectors, setup jumpers etc..

The default loaded “Charon 2 DB demo” applications is well documented (“Charon 2 DB demo page”) example of using all these peripherals.
You can find detailed Getting Started guide in the Charon 2 Development Kit manual.

Setup the IP address

At first you have to assign unique IP address to the Ethernet device. We are not supporting the DHCP because of some troubles and uncompatibilities with previous versions, we prefferes easy serial terminal setup.
Run any RS-232 terminal program (Hercules or Tera Term for example) with port parameters: 9600Bd, no parity, 8 data bits, 1 stop bit (9600 8N1). Switch the handshake control off (Flow : NONE). After power up with shorted the “SETUP jumper”, the first page of the serial setup should be displayed in the opened serial terminal.

RS-232 Setup is intended for use in setting Charon 2 network parameters. Before you connect the Charon 2 Development Kit into the network, the parameters should be set to the correct values for proper operation on the network (accessing the Charon 2 Development board from network).

You can see this page on the picture, follow the instructions and “Press any key to enter RS232 setup“.

The actual configuration is printed, and can be seen in the easy menu allowing change of basic network parameters.

When the Charon 2 DB peripherals demo firmware is loaded into the microcontroller, these network parameters are set to default values:

MAC= 00-0A-59-03-00-5F,
IP=192.168.1.100,
IP mask=255.255.255.0,
IP gateway=192.168.1.1

Just press “I” or “i” (non case sensitive) to assign an IP address for the device. There is automatic mode inserting "." (dot separators) if the number in the IP address is 3 characters long. There is ENTER automaticly inserted if the last number has 3 characters. You can't use backspace key in editing..
All entered paramethers are automaticky checked before writeing to the EEPROM = you can't set GW which is out of your basic IP address range defined by the IP address and used Network MASK. It means you have to define first the module's IP address and Network MASK, than new GateWay.

When all paramethers are OK, remove the “SETUP jumper” and press “R” for “R: Reboot (exit setup)”.

Testing default WWW application

The user can access the “Charon 2 DB demo page” HTML page by an internet browser. Simply write the current Charon 2 IP address into the browser and the following page appears. The default IP address =192.168.1.100 , in browser: http://192.168.1.100.

There is a ‘welcome’ HTML page and from this page the user can enter to other pages (links on page):

On NutOs status HTML pages we can see some important NutOs operating system information. The main purpose of the implemented application on Charon 2 is peripheral control. Therefore the most important link is Peripheral control to show the following HTML page :


Now you can work freely with this default application. For more details about peripherals and their programming support, please check the “Charon 2 DB demo page”.

You can test this demo online on our public IP address : 80.250.3.195 in our Prague office.
