I2C Library

I2C Library   https://projects.drogon.net/raspberry-pi/wiringpi/i2c-library/ WiringPi includes a library which can make it easier to use the Raspberry Pi’s on-board I2C interface. Not all systems have the I2C development libraries and headers installed, and when you buildwiringPi, it detects this at build time. If you are using these helper functions and you get link errors, it means that wiringPi is not installed with the I2C helper functions. You need to install the I2C development libraries and re-build. Under Raspbian: sudo apt-get install libi2c-dev then

Configuring I2C

Configuring I2C http://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c I2C is a very commonly used standard designed to allow one chip to talk to another. So, since the Raspberry Pi can talk I2C we can connect it to a variety of I2C capable chips and modules. Here are some of the Adafruit projects that make use of I2C devices and modules: http://learn.adafruit.com/mcp230xx-gpio-expander-on-the-raspberry-pi http://learn.adafruit.com/adafruit-16×2-character-lcd-plus-keypad-for-raspberry-pi http://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi http://learn.adafruit.com/matrix-7-segment-led-backpack-with-the-raspberry-pi http://learn.adafruit.com/mcp4725-12-bit-dac-with-raspberry-pi http://learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspberry-pi http://learn.adafruit.com/using-the-bmp085-with-raspberry-pi   If you are using Occidentalis, then your Pi is ready to go with I2C as far as

Looping video playlist with Omxplayer on the Raspberry Pi

Looping video playlist with Omxplayer on the Raspberry Pi http://www.cenolan.com/2013/03/looping-video-playlist-omxplayer-raspberry-pi/ The Raspberry Pi comes with an awesome little video player called Omxplayer that is very capable of playing back full 1080p video perfectly when encoded correctly in H.264/AAC. One problem is the current lack of playlist support in omxplayer, so this post explains how to create a bash script that will permanently loop through and play a directory of videos.   First install omxplayer: sudo apt-get install omxplayer Now create this script named for

Looping videos seamlessly OMXPlayer

http://www.sundh.com/blog/2013/10/loop-videos-seamlessly-omxplayer/ Looping videos seamlessly OMXPlayer Ellen 16:30 on October 15, 2013 As I looked for different solutions for looping videos on the Raspberry Pi seamlessly I eventually came out with a solution that worked quited good for videos looping with sounds. Looking at the possiblities of using the existing example of hello_video/video.c to loop a video wasn’t an option as sound was not supported and syncing sound was not something I wanted to spend time on. Instead I looked to jbaiter’s OMXPlayer library pyomxplayer build in
