I have two Python codes for reading a SHT21 temp/hum sensor, but they give
different readings! I know the difference seems to be small, but the sensor
is located in a place where temperature is very stable, and both of the
scripts show the same reading almost all the time (the sensor is not
bro
So, how to set rising edge detection in pruio-lib without the following
while-loop:
pruIo *io = pruio_new(PRUIO_DEF_ACTIVE, 0x98, 0, 1);
int gpiovalue;
while(1) {
gpiovalue = pruio_gpio_Value(io, PIN);
if (gpiovalue == 1) {
///capturedatacode...
}

Hello
I need help with reading the MLX90614 ir sensor... When I attach it to BBB
and run sudo i2cdetect -y -r 1, it slowly looks for i2c addresses and dmesg
says "controller timed out" every time.
The problem seems to be in the MLX90614 communication, because if I plug it
out, i2cdetect finds
Tried that too. I temporarily changed the os to Arch and it does shutdown
BBB. Anyway I would like to use Debian and there is undoubtedly something
wrong.

Here is a syslog after shutdown command (don't know how much is missing,
after 10 minutes of hanging I turned it off):
> Oct 4 22:11:25 arm shutdown[3524]: shutting down for system reboot
> Oct 4 22:11:25 arm kernel: imklog 5.8.11, log source = /proc/kmsg started.
> Oct 4 22:11:25 arm rsyslogd
Not working. CPU and heartbeat leds keep blinking, but it won't respond any
ssh command or ping anymore. So it hangs of shutdown.

Tried halt -p, reboot and shutdown. Nothing turns power off my BBB and I
have to physically turn off it. Also tried with 3.14.17-bone8 and
3.8-13-bone67. Distro is Debian, running from eMMC.

Here's my situation: I have a device with four pins: GND, Vin, data and
DTR. When DTR is pulled low, device sends digital data to the data line. I
know the bit length and the data message length, but the question is, how
can I read the data (zeros and ones) with a Beaglebone Black?
Just to clar

I do not have dropbear, I'm using openssh. Are you able to ping to your BBB
when the problem exists?
If you can't, you have the same situation as I do.

Hi and thanks for your reply.
I compiled the kernel and think everything went well - though the compiling
was the first time for me.
Running Debian Wheezy and just replaced old kernel files and modules,
result: no errors, so maybe the kernel configuration is ok?
uname -a
Linux arm 3.13.0-rc6-bo
I confirm this issue is not only related to Arch, but also Debian Wheezy.
They detect Easycap dongle fine, but motion doen't want to capture video
from it.

I have my BBB connected to a ADSL modem/router in bridged mode, so BBB gets
directly an external IP. But sometimes, actually many times an hour, it
doens't respond to any protocol: I have tried pinging, ssh and http-request
but nothing reaches BBB (connection timeout). However, I have set a cron

Thank you! I used the latest 3.12 kernel and installed the legacy version.
Now my program works fine!
By the way, why doesn't the newest kernel support the capes?

I managed to compile BBIO and before that I installed python2 packages.
Now there's a new problem, let's see following code
import Adafruit_BBIO.ADC as ADC
ADC.setup()
value = ADC.read("P8_36")
voltage = value * 1.8 #1.8V
print voltage
It should print the analog pin 5 value, but this error app
