ATMEL AVR workshop

Instructor: Chikashi Miyama

Why AVR ?

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 / installations.

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!

ATMEL AVR ATMega 88

Though there are more than 100 variant of 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 specification for further information.

What workshop covers

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.

I. DEMONSTRATION (90 minutes)

In this section, I will introduce basic speciﬁcation, procedure of AVR programming, and various applications of the chip by showing different pre-built circuit based on the AVR chip.

1. Overall information of the chip

Where you can buy chip
Price / model list
Basic speciﬁcation of the chip

2. How to program AVR chip on Mac and Linux

How to use avrgcc and avrdude
Commercial Writer AVR ISP MK II - 34$ (Fig.1)
Handmade Writer USB ASP (Fig.2)
Using Arduino as AVR writer (http://arduino.cc/en/Tutorial/ArduinoISP)

3. Applications

How to create LED ﬂasher
How to create MIDI message generator
How to create Potentiometer to MIDI device by using built-in ADC
How to send serial (UART) messages from the chip and receive them in Pd
How to use USB message without any other device [project ﬁrmware based USB device using AVR]
How to use timers
How to use PWM and create sound with it
How to establish SPI connection in order to access external memory, ADC etc.
How to create AVR programmer by yourself
All source codes and schematics will be uploaded online so that the participants are able to download and utilize them later

II. PRACTICE (90 - 120 minutes / depending on the number of participants and competence )

In this section participants will make a basic hardware using AVR microcontroller. Possibly, 6 channel MIDI or USB-based digital controller based on gnusb by anyma http://www.anyma.ch/ research/gnusb/ This part is dependent of the facilities of the venue and available components in Germany.

Prerequisites

Basic knowledge of C language and unix commands are preferred
Basic soldering technique and knowledge of electronic circuit are preferred
The AVR programmer runs on Linux, Mac, and Win. I will use linux or Mac for the workshop.

Bio of instructor

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.
