Hey Ivica,

The object is [gpio] and whilst working fine, is pretty basic. Jaime's
helpfile is very useful and recommended.
OAN - Had a quick look at your site for the RPI version of pd-l2ork -
really
Joining late to the discussion--is there now a native Pd external that
allows direct connection to RPi pins or is there still a need to use
middleware to access the data steam? If former, where can one get their
hands on the source--I would love to include it in the next pd-l2ork RPi
release?
Hey Martin / all,
Oh there's much chin scratching and head shaking going on at our end atm...
Can we ask if we have the hardware configured correctly before moving onto
software issues please:
Attached is the diagram of our 4051 mux'er.
This is what we have and aren't sure if it's correct

Ok - thanks for that, makes more sense now.
When I run the C code this happens:
./jb_d6t_reader_ic3 0
...export file accessed, new pin now accessible
...direction set to output
./jb_d6t_reader_ic3: initialized:0
Write failed (5)
Input/output error
...unexport file accessed, pin now

Here's a patch to display data from two D6T sensors on the same I2C bus.
The clock line is switched using a 4051 analog multiplexer. The control
line is GPIO_17 of the Pi connected to A of the 4051 (B, C and Inhibit
are at 0V). 10k resistors to 3.3V are on each sensor's clock line at X0
and X1
Super-useful, thanks Martin.
Will be testing it out in a couple of days so will report back then.

Hi Martin / all,
Possibly overly-nerdy question here:
I'm buying the various bits and pieces we require for the multiplexer and
I'm noticing quite a difference in pricing options for the pull-up
resistors.
There's this one:

This is the multiplexer:

Ordinary 5% resistors will work fine. Probably anything from 1k to 100k
would work. Most likely you have a loose connection somewhere. Did you
try running the bus at a lower speed? If your wiring is long ( 10cm)
it may be better to run it slower.

'Nother 2 dumb questions:
What's the difference between the ones that have spider/centipede type legs

And also are you attaching the MC14051 to any type of board/adaptor or just

Quick edit for archives:
sudo modprobe i2c)bcn2708 baudrate=9
should be
sudo modprobe i2c_bcm2708 baudrate=9
I tried changing the baud rate with
sudo modprobe -r i2c_bcm2708
sudo modprobe i2c)bcn2708 baudrate=9
but it works fine at the default 10.
Hey Martin / all,
Omron tech support finally got back to me re the address issue, this is
what they had to say:
D6T sensor can not change the address.
When you connect multiple sensors we recommend that you use the IC
switching.
Please refer to the below document.
Bit more digging re ic switch:
My understanding is that if we got one of these:

Yes that would work too, if you can handle the soldering ;(
I suppose you could modify the c code to run two sensors and send the
data to two different port numbers, or use two different selectors for
the message. Another way would be to have the Pd patch request a reading
from a specific

Maybe there's something I'm missing here then:
The average temp that comes out of [unpack 1] is way higher than the
