You can use either powered or parasitic modes for One-Wire devices -- there isn't a distinct device for one mode or the other. The data sheet shows the DS18B20 can operate down to 3V. I'm not greatly versed in embedded Linux, nor in the BBB, but I've used One-Wire devices (including DS18S20s)

Thanks, John --- just the sort of thing I've been looking for. As far as kernel development goes, I think I'll stick to popcorn for quite some time. ;-) Cheers, Tim On Friday, September 5, 2014 12:38:22 AM UTC-4, john3909 wrote: From: Tim Cole tim...@rogers.com javascript: Reply-To: beagl

This is probably a very naive question, but I'm leery of mucking about with installing a new kernel until I know for sure. Can the 3.15.10 kernel (or any other, for that matter) be installed without wiping out the rest of the OS? Cheers, Tim On Wednesday, September 3, 2014 11:29:50 AM UTC-4,

Agreed -- you can't learn a damned thing without putting in your own skull time. Perhaps I'm too distrustful of internet search engines -- I like a good reference handbook. If there isn't one available, I'll just have to make do. On Thursday, September 4, 2014 6:24:04 PM UTC-4, William

[beagleboard] How to determine hard float vs. soft float

2014-09-03 Thread Tim Cole
Greetings all As I understand it, the Debian distribution installed on the most recent BBBs is configured for hard float. If I were to install another flavor of Linux, or even an updated version of Debian, how would I determine if it's been configured to use hard float or soft float? Is there

So, I'm guessing it's a case of sacrificing performance for portability and robustness. My first reaction is that it seems odd, but then again --- make it work before you make it faster. Thanks! On Monday, August 18, 2014 1:54:39 PM UTC-4, Jerônimo Lopes wrote: I think... It's one of UNIX

? If you need fast though, a PRU + mmap can achieve fairly insane speeds. 10Mhz or better should not be a problem. On Mon, Aug 18, 2014 at 12:18 PM, Tim Cole wrote: So, I'm guessing it's a case of sacrificing performance for portability and robustness. My first reaction is that it seems odd
