Title: 1-wire library on Digx
Post by: aerohost on January 01, 2014, 11:59:51 am: Hi, just received my Digx with level shifter board - it looks very capable. My primary focus is on 1-wire sensors, is there any info anywhere about using Digx with 1-wire, can't seem to find anything.

Tks, AB

Post by: aerohost on January 08, 2014, 11:20:05 am: Hi, so I installed everything and uploaded the DS1xS20_temperature sketch into the digx. It doesn't work, so I'm wondering why. The serial monitor just keeps displaying 'no more addresses' so I know the script is running.

I had it working on a Yun using 5v, but I hooked it up to the 3.3v supply on the Digx. Does anybody know if I still need to use the 4.7k resistor if using 3.3 instead of 5v? Will I blow something if I use 5v supply?

Tks, A

Post by: aerohost on January 08, 2014, 02:00:44 pm: Hi, works fine, thanks. Didn't realize it was a double header and had the wire connected to the outer port. Duoh. Too much I/O for me. :)

Post by: aerohost on January 08, 2014, 08:20:48 pm: Hi, so I have run the Bonus Temp example with 3 temp sensors plugged in with short wires on a breadboard. I'm running into the same problem I had with the Yun in that the sketch will run for perhaps 6 or 7 hours, then just stop. Any ideas?

Tks, A

Post by: digistump on January 08, 2014, 09:50:37 pm: I imagine the OneWire library has a timer/variable in it or similar that is overflowing - in what way does it stop - no more output to serial? or just can't find the sensors?

Post by: aerohost on January 08, 2014, 11:19:34 pm: the serial monitor stops and the board has to have the sketch uploaded again to restart,cold boot won't do it ...

Post by: aerohost on January 09, 2014, 08:07:52 am: Hi, so I started another test yesterday afternoon and let it run all night, and it was still running this morning, so perhaps all is ok. I'll continue to monitor it.

Tks, A
