Super. Well . I'd send you a board if I thought it not so specific to my application, but in lieu of that, you will certainly get gratitude, some blog love, and the satisfaction of seeing your code deployed and adopted into many neat environments. To expand, I use RF networks of sensors, and

So the 328 is already set up as a target, or would I need to write a target def in the world config? I have circuits already built where one or both of the hardware interrupts are being used, often for RF. C > On Sep 2, 2015, at 3:20 AM, Matthias Urlichs wrote: > > Hi, > >> Sounds great.

Sounds great. What are the chances of getting this ported to something like an ATMega328P with a selectable bus line? It would open up a lot of possibilities. Colin On Tue, Sep 1, 2015 at 2:34 PM, Matthias Urlichs wrote: > Colin Reese gmail.com> writes: > > > > > > > I made it through al

Thanks. I'm typically using the Arduino IDE but I'll take a stab at it. I did eventually get into the Makefile and realized the files were generated this way. I ran back to the shop to grab a handful of 328Ps and my target boards so I'll try the other code as well. Colin > On Aug 30, 201

Owslave has been superseeded by the M-O-A-T project: https://github.com/M-o-a-T/moat, and from my brief use (a few months back, testing only) it works really well, at least on a Mega 8. There was an introductory post on this list a few months back. You need to edit the .cfg file to build a con

Anybody have a reliable codebase for ATTiny85 1Wire slaves? The best code I've found is written for a 328P and needs to be ported: https://github.com/neuoy/OneWireArduinoSlave There is this, mentioned on this listserve some time ago, but it seems to have a broken dependency for dev_config.h wh

That's why I suggested using the MAX31865. It's an SPI RTD reader. I use it already, but would prefer it on a longer multi drop bus where an IO per chip select is unnecessary. It's 3.3V so either the 1Wire bus is on 3.3V (as well as the micro), or you use an LDO to bring it down to 3.3V for the

2015-08-28 Thread Jerry Scharf
Colin, The reason I and most other people use RTDs is because they are more precise than a typical thermocouple or thermister. You need to do a good bit more than an LDO and a A/D to make the reader as/more stable than the RTD. Everything needs to be temperature compensated with careful circu
