YADC - Yet Another Design Contest

This one is organised by Lantronix to promote their XPort Pro, world’s smallest Linux computer (according to Lantronix).

The contest is open to all individuals with interest in network technology, including businesses, university faculty, students, research labs, engineers and design contractors. There is no limit to the number of entries per person or organisation. Prizes of $6,000 and $3,000 will be awarded to the two top entries for Best Linux Design, and a separate prize of $3,000 for the Best Student Linux Design.

To enter you have to buy an XPort Pro evaluation kit for $99. This is bearable, but will probably limit the number of participants.

Become a beta tester and win

It is contest time. I allready mentioned the Luminary, sorry, I mean Stellaris ARM contest from Texas Instruments together with Circuit Cellar and a week later the LPCXpresso ARM contest by NXP. Now it is Freescale who organises a contest. OK, this is not a very difficult contest and you don't have to design anything, but you can win some smart prizes.

To participate you only have to enter the CodeWarrior Development Studio 10.0 beta test program. Free access to the beta release, including full documentation and task-based videos are available for a limited time at CodeWarrior integrates the development tools for the RS08, HCS08 and ColdFire architectures into a single product based on the Eclipse open development platform. Since this is a beta release, it cannot be used for the development of production products. However, you are encouraged to explore the functionality of this new development environment.

To recognize your participation, on April 12, 2010 Freescale will be drawing names from the pool of beta testers for three exciting prize packages:

- Canon Rebel digital single-lens reflex (SLR) camera
- Wii game console by Nintendo
- Garmin handheld GPS

So, go get that 500+ MB download and win that camera!

P.S. You have to submit feedback through a Freescale Service Request to really enter. Alternatively, participants may send an email with name, address (including zip code), home and work telephone numbers (including area codes) to

LPCXpresso design contest

Last week I received two LPCXpresso boards designed by Embedded Artists for evaluation. An LPCXpresso board is a small but longish 35 by 140 mm board split in two parts. One part has an ARM Cortex (M0 or M3) processor from NXP (LPC1114 or LPC1343) on it, together with a 12 MHz crystal and a small prototyping area. The other part of the board is the LPC-Link, which is a real JTAG programmer/debugger. This part is a sort of detachable JTAG pod and if you cut the connections between the two rows of JTAG connector pads you can connect it to other compatible hardware, your own ARM board for instance.

Why is this interesting? Well, first of all because of the price, since Embedded Artists sells it for only 20 euros. This means that you can get yourself a JTAG debugger for a very good price.

Then there are the development tools (Windows only, but should also work on virtual platforms with USB support on other operating systems). The boards are supported by a free enhanced Eclipse-based IDE developed by Code Red. This software lets you compile programs of unlimited size, but program and debug only up to 128 KB. The NXP web site has a list of compatible processors which is unfortunately missing the LPC2148, but according to NXP it should work with unlisted controllers too, as long as you respect the 128 KB limit. I have yet see this as the IDE does not allow picking an incompatible controller and an LPC2142 is not an LPC2148.

LPCXpresso LPC1114 together with an mbed module and the mbed pin-out card. Everything on the left of the pin-out card is the LPC-link JTAG pod.

Note that the LPCXpresso is pin compatible with an mbed board. That may seem strange as an mbed module only has 40 pins whereas an LPCXpresso has 54, but pin 1 to 20 and pin 28 to 47 of the LPCXpresso module have (where possible) the same functionality as the mbed pins. One problem though, the mbed processors (LPC1768 and LPC2368) are not supported by the LPCXpresso IDE. I have been told though that a Cortex-M0 mbed is coming soon.

Also interesting is that NXP has launched a design contest. Anyone entering a valid design concept before the 8th of March 2010 will receive a free LPCXpresso development kit and then has about one month to actually build it and show that it works. Check out all the details here.
