just released! well there is a nice article about 3 different Audio-dsp boards from Eric Brombaugh as well Antti http://groups.google.com/group/antti-brain/files?hl=en
50+ pages fresh from Antti's brain

I downloaded it a few times. Michael Kellett

Maybe try right click and "save as", then open the PDF, not within the browser, sometimes Acrobat Reader has problems when loading it from within a web browser. BTW: the W7100 microcontroller sounds interesting: 64 kB flash, 64 kB SRAM, 32 IO ports and TCP/IP for $6.40 ( http://tinyurl.com/yev4vzy ). -- Frank Buss, fb@frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de

Maybe next time post it to sci.electronics.basics :-) The magnetic pendulum idea sounds interesting. Do you think it would be possible to build something similar with only one coil for hovering things like this: http://www.paramountzone.com/globe.htm ? -- Frank Buss, fb@frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de

The smallest one of the LPC1700 family with network support costs about the same as the W7100, but has an additional DAC, ADC and USB: http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=lpc1764 -- Frank Buss, fb@frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de

LPC1768 has no ethernet PHY and W7100 has lots of ethernet "in hardware" so for tasks where you need ETH+something and do not need the extras the W7100 maybe better Antti

(ie that $6.40 looks like a promo price ..? ) No ADCs and no SPI port - so the Ethernet pumps nicely into this device, but where does it go from there ? [Could make a nice FPGA peripheral ? ;) ] Seems to need TWO crystals ?, and has interesting ROM/FLASH speed comparisons. ROM looks 4x faster, so they have simple maths libraries included in ROM How well does the W7100 debug tool chain work ? -jg
