Olimex LPC2478-STK and uTasker

Development Boards MicroMod
1

Woo Hoo! uTasker has direct support for the Olimex LPC2478-STK, [Sparkfun sku:DEV-08853

Just to start, I’m not affiliated with uTasker, just happy to see some real support for the LPC2478-STK

They have a demo in binary form you can download and check out for your self:

“This demo includes Fast HTTP, FTP, TELNET, NetBIOS, DNS and SMTP. Includes LCD display demo too.”

To see what to expect, grab the [tutorial PDF.

The demo files are on [this page. Just look for the section labeled LPC24XX

  1. Download both the zip file and the web page files

  2. Unzip the demo and use flash magic to program it into the board.

  3. Open up a terminal session to the serial port, hit return and a menu will appear.

  4. You’ll have to set a MAC address. uTasker reccomends using one from an unused lan card, pc, etc.

Use the hidden comamnd MAC followed by the mac address.

IMPORTANT use “-“ between the mac bytes instead of the “:”

Their example MAC 00-11-22-33-44-55

  1. Set up the lan parameters

Enter “1” to get the lan menu

Type “show_config”

If you don’t like the default ip, set the ip add, mask and gateway

Type “validate” to double check everything is good

Type “save” to store the lan parameters

  1. Turn on HTTP, FTP and anything else you want to try out

You’ll have to type “up” if your still in the lan menu

Go the the admin menu (I think its option 4)

Type “set_http enable”

Type “set_ftp enable”

Type “validate” to double check everything is good

Type “save” to store the settings

At this point you can use your browser to access the board, but the web pages are not stored locally. You’ll need to ftp them to the card. It’s easy because a there’s a .bat file included to handle it.

  1. Unzip the web page files

  2. If you changed the ip address, edit the bat file with the new ip.

  3. In windows, just double click on the file and it will transfer all the html

  4. Browse to the board ip and you’ll see the pages

  5. Click the option for the LCD demo

Hit the browse button and find the image directory in with the inzipped files

Pick one of the .bmp files and hit upload

The picture will show up on the web page and on the tft screen

Hopefully you mention it, else it would be hard to believe :lol: :mrgreen:

Ok, ok, don’t push me, I know where the exit is. :mrgreen:

Hi All, and Kevin of course

Just a couple of notes to explain and sightly correct Kevin’s guide.

  1. The default MAC address is 00-00-00-00-00-00 and this will usually work without any modification (some DHCP servers don’t like allocating IP addresses to this address but in fixed IP address mode it should never be a problem).

  2. The MAC address can also be modified via web browser on the LAN configuration web page - here a single modification from 00-00-00-00-00-00 to any other address is allowed, after which the field will become disabled (gray and no change allowed).

  3. When changing Ethernet configurations (MAC address or other IP settings) the new setting can be saved temporarily - on the web page this is always the case. The board will reset automatically and restart with the new settings. The user should then contact the board using the new address within 2 minutes and command “validate”. This will permanently set the change(s). If this s not done within this time the board will reset and revert to using the previous setting(s). This is a safety mechanism for when such changes are made via Internet - if an unusable set of values is saved (eg. mistyping IP address so that it is unreachable) it will recover itself. This is described in detail in the tutorial.

  4. The menu is available via UART and TELNET but is usually most comfortable on the web page - once the device is contactable.

  5. HTTP, FTP and TELNET are enabled by default so these don’t need to be specifically enabled - they can however be disabled if required.

  6. The specific demo uses the uFileSystem to store web pages. These are loaded via FTP. Generally the project allows several options depending on which is most suitable: the web pages can be integrated into the code (there is a utility in the project to do this) but can of course not be modified without changing the SW version. They can also be located in a single compressed file which is uploaded via FTP - the web server can handle the embedded file content as if it were a group of files - this saves some space since there are no empty blocks within file sectors and there is only one file to be managed. They can be located in internal FLASH or in external SPI based FLASH. Finally the FTP and HTTP servers can work with FAT32 (including long file names) from an SD card if required (falling back to uFileSystem if this is missing). [Note that the SD card driver is SPI based and so doesn’t use the SD card controller at the moment].

  7. Apart from the TFT interface, which is special on the LPC2478 the project runs on most devices from LPC2101, through LPC214X and LPC23XX to LPC24XX. It is also available for LPC17XX devices as well as other ARMs (ATMEL SAM7, Luminary Micro), AVR32 and Coldfires.

8 ) USB stacks are available for some processors and the next LPC2XXX release will support LPC2XXX USB device too (same for next LPC17XX release).

  1. The next release will also include IPv6 (IPv4/v6 dual-stack) - see [http://www.utasker.com/docs/uTasker/uTaskerIPV6.PDF for guide to reserving IPv6 space and using 6in4 tunneling to get real IPv6 based devices operating today…

  2. The project includes a unique real-time device simulator which works together with VisualStudio (V6.0 to 2010) and WinPCap (for Ethernet simulation interface). This allows developing/testing/debugging devices/projects without needing hardware and has generally much superior development and debugging support compared to embedded IDEs and HW testing.

Hi

Note that the uTasker simulator for the LPC2478-STK (that is a simulation of the Olimex board with web server and TFT) is now available as executable - that is a pre-built executable that can be run without installation (http://www.utasker.com/SW_Demos.html#SW_EX).

The user enters the local NIC (in menu LAN | Select Working NIC) so that it can hook up to the network, loads the web pages from the folder “WebPagesLPC24XX” via FTP to IP address 192.168.0.3 (there is a bat file which automates this). Then browse to the web server at the same address and load images to the simulated TFT (test images are in the folder “images”).

Regards

Mark
