Open Source Video Driver for the Raspberry Pi

Broadcom recently announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license. This is good news for the Raspberry Pi community. The release targets the BCM21553 cellphone chip, it should be reasonably straightforward to port this to the Pis BCM2835, allowing access to the graphics core without using a binary blob.


As an incentive to do build a open source video driver the Raspberry Pi foundation will pay a bounty of $10,000 to the first person to demonstrate that they can successfully run Quake III at a playable framerate on Raspberry Pi. This competition is open worldwide, and you can find competition rules here which describe what you have to do, and how to enter.

BitTorrent Sync – Serverless Cloud Storage

BitTorrent Sync is what seems to be a great encrypted serverless Dropbox alternative. You can read more about the technical background here. It provides clients on OSX, Linux, Windows, Android, iOS, ARM and others. The client for ARM can easily be run on the Raspberry Pi. Just download the binary and copy it to your pi. Start it by executing “./btsync”. You can now access a web interface at http://[raspberry IP]:8888/gui. This interface allows you to create new “Shares” or connect a local folder to and existing one.


WebIOPi – Browser based GPIO for the Raspberry Pi

WebIOPi is a webserver and a combination of libraries to control the Pis GPIO from the browser or from any application via HTTP/REST. It also has support for many common ICs like I2C IO expander etc.

The feature list:

  • Control, debug, and use your Pi’s GPIO, sensors and converters from a web browser or any app
  • WebIOPi is the perfect Swiss-knife to make connected things
  • Written in Python, with facilities to load and execute custom script, using a comprehensive structure with setup and loop functions
  • Unified Serial/SPI/I2C support with a complete and consistent set of functions to control more than 30 devices, including most used analog converters, I/O expander and sensors
  • Javascript/HTML client library to make Web UI
  • Python/Java clients, to make Pi-to-Pi systems or Android applications
  • CoAP support brings the best Internet of Things protocol on the Pi, as a future proof of Pi possibilities
  • Includes simple web apps, to debug GPIO, devices and Serial interface


Raspberry Pi colocation at 100 MBit

The Dutch hosting company PCextreme hosts your Raspberry Pi for free  with a 100 MBit uplink and 500 GB free traffic.

Update: They reached their limit of 2000 units. Colocation is still possible but no longer free.

PTPd – Precision Time Protocol

The PTP daemon (PTPd) implements the Precision Time protocol (PTP) as defined by the relevant IEEE 1588 standard. PTP Version 1 implements IEEE-1588-2002, and PTP Version 2 implements IEEE-1588-2008. PTP was developed to provide very precise time coordination of LAN connected computers. The source code is available on github.
