Networkable controller advice

Over the holiday I was asked what processor would be best (criteria below) that would be able to be networked (web server). While I have my bias, I thought I would throw the question out for a broader perspective and new information.

In this case, the answer needs to be a complete kit rather than getting a processor, emac, compiler, etc. separately. While this may be the best approach for a high volume product, it wouldn't be so helpful to a high school junior with limited summer break time.

I did a quick survey this morning, and the candidates seem to be: Rabbit, Zilog, Freescale/Netburner, Maxim. Microchip seems to be a few months away from a complete kit. There may be others, so feel free to suggest them.

Criteria:

-- 8 or 16 bits (32 ok if low cost, not to complex*)

-- ADC or SPI port (I have an ADC module that uses SPI)

-- Adequate memory for simple projects on-chip/module

-- Some buttons or other I/O to play with

-- C or Java compiler. Don't care for some of these demo versions some companies use.

-- TCP/IP stack included for web server, FTP, and perhaps a few other Internet protocols.

-- Documentation complete, clear, concise.

-- Support competent and responsive, and free or low cost.

-- Cost low, but not necessarily cheap (we get what we pay for!).

-- Able to have progress within a few day or so.

  • I looked at an ARM kit from a company and the web site said that this kit to complex for beginners.

Thanks, Dave

I'm glad netburner is on your short list. I would recommend that you take a look at the videos on our web page to get a feel for how our products work.

We have a 30 day money back guarantee, you can try one of our development kits and return it it does not do what you need.

If you have any specific NetBurner questions please feel free to contact us via the contact information at

If your application is small and you are willing to trade some capabilities against lower cost then wait a few months we are working on a new product using the new freescale MCF52234 a single chip 32 bit solution with ethernet MAC and PHY on a single chip. More details will be announced at Freescale FTF in about 3 weeks.

We have been evaluating Glomation GESBC-9302 for some time. It's 32-bit ARM9/200MIPS and is probably least expensive in its class ($95). Has ADC and SPI, runs Linux kernel 2.4, comes preconfigured with web server and uses open-source tools.

We have been also using Lantronix' Xport to Ethernet/UART converter, works up to 921k for $49. It's quite stable and allows very fine control of timing and packing and we were able to achieve sub-millisecond added latency when migrating our product from serial to Ethernet. You can use it out of the box to connect to your favorite microcontroller or sign NDA with Lantronix and you will be able to upload your programs compiled with Borland DOS compilers, some available from Borland Museum.

Dave,

I strongly suggest you take a close look at the new MCF5223x line of Freescale controllers. They do have a low cost developement board that comes with all you need for your task, even including said webserver, ADC, SPI, I2C etc etc. on that board, buttons and leds - you name it. The board is only $99 and it's available by now - at least that was told me yesterday when I attended one of their seminars in Zurich/Switzerland where they handed out these boards to us.

The controller is very nice in that it is a single chip 32 bit ColdFire solution, including Flash, RAM, Ethernet MAC and PHY (10/100mBit) all on chip - and actually the chip was designed for the very kind of tasks as you describe. You get a free TCP/IP stack, a free task sheduler, the webserver, a ton of examles and also the source code of all this and last not least an eval version of the CodeWarrior IDE whoes only limitation is that the code size can't exceed 128K.
