I want to use two servos with pins 8_13 and 8_19. How can I change the
period? I tried editing the dts file and compiling with
dtc -O dtb -o bone_pwm_P8_13-00A0.dtbo -b 0 -@ bone_pwm_P8_13-00A0.dts, but
the period remains the same. Is there something else that need to be done?
I not sure it
I ran trainCascade on my Linux virtual machine and got an xml file, but
when I try to run it on the Beaglebone I get the following error.
Parsing Error : valid xml should start with ?xml?

I tried the gpio-keys driver. I was able to count the interrupts, but was
not able to determine which pin. I tried the following code, but when I
hooked up switches to two pins the first switch I triggered would give the
correct code, but when I triggered the second switch it would give the
on the output? I believe the best you can get
out of that regulator without a big heatsink is maybe 500mA which is
borderline for the BBB. You are dropping 6.7V across the regulator.

as your issue, i would expect to happen.

supply say 8V and it will run longer. The hole
in the tab of the regulator is for the heat sink.
Now, if the regulator is putting out 7V, then it could be the board.

Make sure you allow sharing under internet settings.
