ok thanks.
i have 2 questions about the scheme
1- if i have a generator that produce about 20v for LCD Backlight(my lcd
want 20 v for back light), should i build the back light circut that get 5
volts as input and amplify it to output ?
2-what is the function of the coil BEAD MLB-160808-0600A-N2

I'm working on building a "universal" device tree overlay that can be
used to enable and switch between most of the various interesting pin
functions (uart, timers, spi, gpio, pru in/out, etc). One problem is
the BeagleBone specific gpio_of_helper driver designed to make it easy
to export GPIO pin

I'm using espeak on Ubuntu with a USB soundcard with no problem. Are
you sure that your sound card works? It may be related to an Angstrom
problem.

yes you were right. We have already programmed with the beaglebone. its
working fine. The derek molloy video we viewed was controlling the gpio
using cpp programming.
Thanks for your help!!

Hi Andrew. Is there a short explanation for why I can't quickly edit the "
*snes9x.conf.BBB*" file and change the lines
*J00:B8 = Joypad1 SelectJ00:B9 = Joypad1 Start*
to something like
*J00:B6 = Joypad1 SelectJ00:B7 = Joypad1 Start*
to effectively test different button mappings? I tried e
Yes. The front-end GUI does not look at that configuration file for button
mapping. That is the configuration file for the SNES9X emulator. Part of
my work for v0.5 is to pull button mappings from that file. v0.5 should
give you the following:

Earlier when I was using Angstrom, I ended up having to download and build
Espeak, but when I converted to the Debian versions, I could install it as
you mentioned.
However the PCM I believe is always defaulting to output to the HDMI
sound. To get it to work with a USB sound card I plugged i
