Hello! Perhaps, perhaps not. Most of the time the company gave ideas on their datasheets, and also using their own talents they've created some dandy application notes. However I now have the whole business talking to my Linux box via USB and its using OWFS, namely the httpd service. It is behaving as expected. However on the Win32 thing I expected to see the counters, ah, count. And indeed that's what I saw there. Has anyone written an application for OWFS which does that? My skills are rusty there. I've also created an Ethereal trace of the whole business, and have it available for those of you who want to replay it before trying something out on their own. I should have a description perhaps photos of the thing online in the next two to three days. But now a description, picture an SN7437 Quad NAND buffer, and a SN7470 AND-Gated J-K flip flop, and for a clock a TSL220 device. The relay is that part of a Clare TS120 device. I have the F/F wired such that one of its outputs is steering pulses into one gate, that gate is talking to the relay. The relay is doing what you'd expect and causes the counter to do its job. However Paul for this release of OWFS namely 2.6p7 (with libow version:2.6p7) everything works here. -- Gregg C Levine [EMAIL PROTECTED] "This signature was once found posting rude messages in English in the Moscow subway." ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
