Restarting going to use universala for uart, pwm, and gpio (MRAA and
ADAFruit_BBIO both work in python)
web cam will be using python-v4l2capture

Just had a WTF moment.
I was working on a BBG image that was still on an sd card. and it appears
as if pwm and uart pins are all properly configured out of the box.
This was definately not the case on the flashed version.
Still trying to figure out if UART actual is working out of the box, it
y I could do this, is by using this command

probally the wrong "uEnv.txt"
dmesg | grep console

ISSUES
LINKSPRITE CAMERA changing the baud rate not very intuitive. soem time the
change is persistent othertime not.
SOLUTION
Always set the baud to default on exit.

7)Setting up a link sprite LS-Y201 camera I bought.
It took some time to get the UART pins to work on the BBG.
ISSUE FOUND:
The UART pins are not enabled by default as UART pins. I tried several
methods, and ended up following the instructions posted here

You received this message because you are subscribed to the Goog
with mraa1.0. Still all the BBIO python
examples are junk. You no longer get a buffer overrun using mraa.write(),
but you can still lock up the pwm.

at slow speeds there would be numerous
missed steps and poor behavior. My oscilloscope showed this to be true at
the BBG and not after the DRV8825.

Don't us bonescript. Now the fun begins, next try Python.

SOLUTION:
I found that if I connected to the BBGw with my phone and clicked "done"
every time the BBGw is turned on or reset, the leds would then go back to
their stated mode of operation. and allow the tutorials to work properly.
