PDCON:Workshops/ATMEL AVR: Difference between revisions

[[Arduino]] is nowadays almost the de-facto standard. Many electronic instrument builders and installation artists employ it for there works. It is easy to use and helpful for prototyping. However, if you want to make 100 copies of your work or if you plan to create a large work involving many micro-controllers.  [[Arduino]] is probably not the best choice; it is too expensive and sometimes takes too much space in your hardware /  

[[Arduino]] consists of several parts. a USB socket, a crystal, a regulator, an ISP socket, a USB-serial chip, several capacitors, and ATMEL AVR Micro controller ATMega328PU.  The Arduino UNO board costs around 34$.  What do you think is the most expensive component on this board?  It is obviously the micro controller. However, it actually costs around 3 - 4$.  

Though [[Arduino]] facilitates many things by offering USB slot and power jack, these connectors are not necessary for all projects. Furthermore, Arduino conceals many potentials of ATMEL AVR chip. For example, you can actually use faster crystals than 16  

Mhz (up to 20Mhz ) but Arduino restricts it by putting 16Mhz crystal on the board.(Probably because they are using firmware based USB connection using second ATMEL chip on the board.)  

This workshop is for people who want to open the hood of Arduino and fully utilize the features of ATMEL AVR chips. I will introduces how to program the AVR chip directly using C language, demonstrates many possible artistic applications of the chip, and practice to build/program a basic AVR-based device with participants. Participants donʼt have to buy anything expensive for starting AVR programming. They can actually use their Arduino as the writer of the AVR chip!  

Though there are more than 100 variant of [http://www.atmel.com ATMEL] AVR microcontroller.  http://www.atmel.com

The workshop focuses on ATMEL AVR ATMega 88 PDIP. It costs around 3$ and available all over the world. It offers 131 powerful instructions,  on-chip multiplier, 6 PWM channels, 6 10 bit ADC, SPI bus, and various timers. It runs maximum 20 Mhz with an external crystal.  

Refer to the [http://www.atmel.com/dyn/resources/prod_documents/2545S.pdf specification] for further information.  

AVR chip offers very many functions and it is impossible to cover everything in limited time. So I would like to separate my workshop into two parts; demonstration and practice. The workshop is going to be around 3-4 hours.

Chikashi Miyama is a composer, video artist, interface designer, and performer. He received his MA (2004) from Kunitachi College of Music, Tokyo, Japan, and Nachdiplom (2007) from Music academy of Basel, Switzerland. He is currently attending the State University of New York at Buffalo for his ph.D, and teaching electronic music as a TA. He has studied under Takayuki Rai, Georg Friedrich Haas, Jacob Ulmann, Erik Oña, and Cort Lippe. His compositions have received a second prize in SEAMUS commission competition (2010/St. Cloud, USA), a special prize in Destellos Competition (2009/Argentina), and a honorable mention in the Residence Prize section of the Bourges Electroacoustic Music  

Competition (2002/France). In addition, he was selected for SUNY chancellor's award (2011/USA). His works and papers have been accepted by ICMC ten times, by NIME four times, and selected by various international festivals in more than 100 times in 17 countries, such as Mix, Re:New (Denmark), Musica Viva (Portugal), Espace sonore, dBâle, SHIFT (Switzerland), Next generation (Germany), Agora Resonance, Scrime (France), Lica-Mantis (UK), June in Buffalo, NWEAMO, SPARK, NYCEMF, SEAMUS (USA), Sonoimágenes (Argentina), SuperCollider symposium, Pdcon, and Dorkbot meeting. He is going  

to move to Karlsruhe and work at IMA, ZKM as a guest researcher in 2011 and 2012 taking advantage of DAAD scholarship.
