Then you just enable the i2c interface through raspi-config, run

I'd really like to integrate a serial device natively via a custom device in

I was unaware of the aliases you mentioned, but included with those I

i2c_vc=i2c0
Thus, including dtparam=i2c and dtparam=i2c_arm or dtparam=i2c1 is
redundant, as are dtparam=i2c_vc and dtparam=i2c0.
NB, be careful with i2c0. It's really only there to service the

The only trick is getting the i2c bus up and recognized, but that's just

I unfortunately cannot read your ascii art, which in itself is disappointing.
2k is a bit low for a divider - you'll get standby current of 6mA. You should
also try optimizing the split to fit the range you can measure. So you'd want a
ratio of R2/Rtotal =measured range/ measurable range. So 2.
And that's easy to do. I database everything immediately including device type
and other metadata and separate control scripts act on data, including device
presence.
If time response is important, you can insert the response functions into the
detect script as well. Read devices, check agains
Yes just run a micro controller non-stop and have it announce presence over a
serial port.

Hello all,
Here is an interesting wrinkle that is not really owfs, but is
1Wire-related, so I thought you might have some insight.
I'm using OW on an arduino using the OneWire Library, and checking
repeatedly after issuing a T Convert command with a DS18B20 to determine
exactly when data is re
Parasitic is less error-prone? Why is this?

That sounds about right to me.

Read scratchpad is pretty darn fast. I'd have to go back to my notes to see
exactly how fast. If I remember correctly, the convert will take something
like 1mA per device during conversion.
You can also take turns with bunches of devices, reading a smaller subset
so as to optimize load on the bus.

Like I said, it works great using the TMEX API. I use LabVIEW with it.

Hello,
After talking with iButtonLink, it was brought to my attention that without
additional power, it is possible to have unsuccessful simultaneous read if
too many sensors are on the network, due to current draw during the
conversion.
Using the TMEX API, I can perform a match ROM and then issu
Where $15 ds9490? Last time I bought one it ran me close to $30.
Why such negativity on the i2c masters? I use them all over the place with no
problems. They're also <$1.

Well, this isn't quite over yet. Still randomly crapping out.
Can someone please help me debug this?
Thanks,
