thanks for the link. looks like this thing does not run really fast, although i did not find anything about sampling speed. it although does not look like sync sampling (with ext sampling clock) is supported. to me, it still looks like it would be the best to build something from scratch, like: an fpga chip, containing the sampling logic, configurable pattern comparison for triggering, and an sdram controller. this would allow to sample data at a very high speed, up to 20mhz or above, still able to sample over a useful time, as sdram is real cheap now. then, a pic would be required to interface the whole thing to a pc, using a serial interface, or better usb. i think, the samping and storage thing would not be such a big job, but getting an easy to use, user friendly control tool on the pc, to control the whole thing, seems to be a very big job, that i don't think i would be able to do without using all my time. any idea? tino Larry Williams Gesendet von: pic microcontroller discussion list 14.07.03 09:24 Bitte antworten an pic microcontroller discussion list An: PICLIST@MITVMA.MIT.EDU Kopie: Thema: Re: BG Micro Logic Analyzer? http://www.bgmicro.com/pdf/softla.pdf Martin.Buehler@KEYMILE.COM wrote: > > is this bg micro soft la a real good thing? > what's the possible sampling rate? how fast is your computer?
