On April 4th, 2010 March 21st, 2010 there will be an OpenToko workshop about Communication Protocols.

In the field of telecommunications, a communications protocol is the set of standard rules for data representation, signaling, authentication and error detection required to send information over a communications channel. … Communication protocol is basically following certain rules so that the system works properly. [wikipedia]

Lots of stuff out there communicates in certain electronic languages: internet, radio, television, telephones, computer screens, computer networks, USB devices, remote controls etc. This OpenToko will cover the similarities and differences between quite some protocols.

Edwin Dertien will kick-off this Toko giving a general introduction and supplying a context dividing the day in the 7 OSI-layers.

In the morning protocols within the low-level ‘media layers’ (physical layer etc.) will be covered. Followed by higher-level protocols from the ‘host layers’ in the afternoon. This sounds quite theoretical but of course lots of nice hands-on stuff will be supporting each layer (like MIDI devices, DMX controllers, VT100 keyboard from the 70′s, DIY AM Radio, Arduino generating video signal, OpenSoundControl iPhone-MaxMSP link and more).

Introduction

10.00 Introduction of the topics and schedule of the day by Edwin Dertien.
10.30 Introduction-round to get to know each other.

Media layers (1 t/m 3)
11.30 Modulation techniques by Harmen Zijp
12.00 Onewire, I2C, RS232, ethernet etc.: physical (1) layer by Reinder de Haan
12.45 Lunch
13.30 Ethernet/TCP-IP: datalink (2) & network (3) layers about routing etc. by Reinder de Haan.

Host layers (4 t/m 6)
14.15 Transport layer (4): reliability etc. by Edwin Dertien.
15.00 Higher data layers: session (5), presentation (6) & application layers (7): DMX, MIDI, OSC etc. by Leo van der Veen and Harmen Zijp.

16.30 Drinks?

Next toko be held at 31th of January 2010. The topic is “Without Wires”. It will address wireless communication of any kind. This Toko a lot of people will share their knowledge about one specific wireless protocol with the rest. At the end of the day, we hope to have covered everything. If there is any wireless topic you think you know enough about to share it, or if there’s one thats not in the list, that you want to learn about, please let us know. Here’s the list so far:

• Bluetooth Arduino (Rick)
• Wireless USB (Rick)
• Wireless VGA (Rick)
• RF transceiver (Edwin)
• Mesh Networking with Wi-Fi (Jaap) zie: http://tuxic.nl/site/cursussen/73-mesh.html
• Time registration in sports with RFID (Egbert-Jan)
• RF Link Transmitter & Receiver 434MHz (Adriaan)
• XBee (Edwin)
• Bluesense (Peter)
• Lantronics eternetshield voor Arduino icm draadloze router.
• etc.

This Toko will be hands-on, so please bring some ‘wireless material’ so you can do your own experiments. At the end of the day everyone will give a short demo about the results.
