- the cross-country advertising truck I drove six months of the year for fourteen years has gone out of business... I can play with my electronic toys full-time, now --- in 2008 (?) - I bought 250 SX-28's to supply me until forever (I'm 74, now).
- today's problem:
-- I cannot get a valid answer from DS1822 1-wire temperature chips, even though I was successful once, two years ago.
-- I am savant (and modest) at assembly language, and have, just this week, read well-written instructions from many 1-wire sources.
-- It MUST be that have the speed incorrect. I have checked and checked everything else for almost ten days...
-- Does anyone remember ??? -- How many RTCC's make up a microsecond ????
-- I have been guessing, "four" --- that is: at a Freq of four million, an SX-28 routine (delay) of 28-RTCC's takes seven usecs to execute.
-- but yet I am getting no response from the sensors.

-- Thank you
