Really ouch. I you do it like this and connect your BB(B) to the lan,
then all computers in your school are under tension (Brrr)!
Therefore: NEVER USE A VOLTAGE DIVIDER WITH NET CURRENT, unless you
really now what you do!
You need to have a galvanic separation like a transformer or a diode.

Could I know if you make this cape works already ? if not, and I make some

Ok, I did a cycle of the reset pin on the sensor board, and now it responds

this is using pins 19 for CLK and 20 for DATA.

Well, so I think I understand a bit more about the DTS support for GPIO. I
configured the pinctrl for GPIO5 channel, and it seems to have some effect
on the GPIO pins. After the kernel starts up the LEDs are being turned off.

I would buy this card but i need some informations:

From a HW perspective this is controlled by changing the clock speed of
the processor inside the processor and lowering the voltage on the power
rails using the power management IC. It is supported in the kernel.

Thanks, Gerald. So what is the normal default speed that the processor runs
at in the BBB?
Or does it vary depending on what? I only need high speed for short bursts
of one second intervals.

Under Angstrom we generally we have the automatic mode on. It can vary
between 300MHz 600MHz 800MHz and then 1GHz bases on the settings you pick.
It has four modes, Conservative, ondemand, performance, and power save.
You can add a control for it by adding it to the top tool bar. To do that:

That should have worked. The only thing I can think of is that there may be

of the power supply you are using for the 5V input on pins 5 and 6. Make

So I've been struggling with I2C. Somebody on this list gave me the tip to
do:
echo BB-I2C1 /sys/devices/bone_capemgr.??**??/slots

i2cdetect -y -r 1 on pins P9_19 and P9_20. Although, after doing that,
you'll have an i2c1
Nevemind, that may be unrelated. I just rebooted and my device enumerated
fine. I think what's confusing (me) is the I2C2 by the SRM (P9_19/20)
