Raspberry Pi GPIO general info and scripts

GPIO Info http://raspberry.io/projects/view/reading-and-writing-from-gpio-ports-from-python/
File System GPIO activation https://sites.google.com/site/semilleroadt/raspberry-pi-tutorials/gpio
WiringPi c Lib http://wiringpi.com/
GPIO info from raspberry pi org https://www.raspberrypi.org/documentation/usage/gpio/
GPIO Benchmarks http://codeandlife.com/2012/07/03/benchmarking-raspberry-pi-gpio-speed/

i/o for this project

Using this reference https://www.raspberrypi.org/documentation/usage/gpio-plus-and-raspi2/README.md
and https://sites.google.com/site/semilleroadt/raspberry-pi-tutorials/gpio

GPIO Port 4 for HOLD (setting as 1 sets GPIO 4 to 3.2v)

sudo su
echo 4 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value


notes, this is obviously volatile... on reboot GPIO4 is high appears high, but is actually floating. It appears to drop low when direction is set to 'out'

Audio Output

HF: Sound output of some sort to a small speaker (I2S?), also 3.5mm audio to car audio input. Hardware switch to turn small speaker off (for music play etc)

Pi Camera Snapshots and Video

Pi Cam getting started https://www.raspberrypi.org/learning/getting-started-with-picamera/

More Pi Camera & Python info http://www.makeuseof.com/tag/raspberry-pi-camera-module/

Dashcam Video Store

- Connect dashcam via usb to pi, remove files from dashcam when stationary... upload to server when in wifi range

Music Server

- MPD server
- sync of music when in wifi range

Navigation

Some sort of audio only navigation... i.e. select preset from menu, audio navigation?
