It's nearly 10 years ago I developed 1 wire slaves based both on PIC and PSoC from Cypress. Since that time I forgot about. But I see the subject is still alive in spite of Dallas, seems to me, is going to go out of 1 wire step by step. I do remember 1 wire slaves subject from 1-wire discussion list (R.I.P.) at Dallas (before Maxim era) and my private messages with David Smiczek (Dallas), Chris Fox and others. 1. I don't know these days practice but that time I was informed 1 wire protocol is Dallas property. It can be used for free ONLY for slaves of Dallas origin. It is patented and selling of third party slaves was (is?) not accepted by Dallas/Maxim. I wouldn't like to start lawyers discussion...only report Dallas point of view that time. 2. I know about 1 wire a lot. I made hundreds of installation (mostly food industry) and, to tell you the true, I gave up with and turned to RS485. Even with iButtonlink master interface which is most advanced and the best I know. It work (till now) with network being ca.3 km long (divided into segments) and few tens of slaves. 1-wire for professionals is definitely not an alternative. For hobbyist...hm... What a market is it ? 1-wire noise immunity, reliability and so on is far behind expectation. It's not as cheap as you expect and if you wouldn't like to have a network which work depending on the moon phase just turn to other solution. I understand you like to get a lot for few cents but on my point of view (producer, designer) it's the road to hell. For my customers, to that of them for whom saving of money is the most important factor, I always say...would you like to have a system for few $ per point which will be responsible for eg. meet store with few hundreds tons of meat ? If yes just don't waste my time.
