JED AVR200 Single Board Computer using the ATmega32 CPU

AVR200 Project board now in production AVR200 SBC

The $A90 AVR200 kit (plus GST), ($A185 built and tested, plus GST) is a low cost ATmega32 based board for industrial/educational/hobby applications. 

This board features in two feature articles in Silicon Chip magazine:
Part 1
Part 2

Protected I/O is provided from all ports to screw terminals and it also provides a RTC, SPI, RS232, buffered I2C bus (and an RS485 option).

The kit features in June/July 2005 Silicon Chip (Australia) magazine P84/91.

It is all through-hole construction and easy to build without SMT hassles.

Availability: AVR200 kits and fully assembled Rev 0 boards are now shipping from JED. (Rev 1 PCBs are shipped if RS485 option is ordered.)

An accurate voltage reference option and an RS485 option is available, and the "standard" build has 8 analogue inputs to Port A, 11 protected digital inputs (Ports B and D), and 9 FET outputs (Ports C and D).

A serial RS232 port is standard to a D9 connector, as is a buffered I2C port and a battery-backed RTC.

Options:

When ordering, please indicate whether you need the MegaLoad utility pre-loaded into the CPU you are ordering.
If you do NOT, you have to use an AVRISP or a STK500 (see below).

All boards are supplied with two CDs:

Test system example ... how to build a test system with LOTS of I/O

The system shown in the photo below shows how to start with a plank of wood and build a end-of-line test system for testing manufactured cable/interconnect systems. The system uses an AVR200 CPU (far right) as the "brain" and a bank of four AVR212 FET output boards (red LEDs below) and eight AVR213 input boards (green LEDs below).

The program in the AVR200 drives a LOW onto each of the 32 inputs of the system under test in various combinations, and then the 64 inputs lines are read in by the AVR213s to the AVR200.

A 32-line table sets up the expected responses, and if an error occurs due to a short, open or swapped line, the expected results differ from the table. If it all agrees a  green LED lights. If an error occurs, a red LED flashes. This gives immediate results on a production bench test. Any faults are reported over the serial port to a PC, listing pin numbers and faults found. (The 10-way grey ribbon  I2C cable can be seen in the photo looping through all twelve expansion boards.)

The driving software is available to interested inquirers as an example of how to program the I/O boards on a AVR200 I2C expansion bus from BASCOM.

"Floribots" at the National Gallery of Australia

Floribot
Here are some images and a movie of the Installation of "Floribots" at the National Gallery of Australia.
Floribots has attracted a lot of attention and has appeared in the newspaper and on TV.
About 100,000 visitors are expected to the exhibition.

Congratulations: Geoffrey has just won the "$4000 Macquarie Bank people's Choice" award at the National Sculpture Prize and Exhibition  for the Floribot project. Well done, Geoffrey!

Floribots is an interactive kinetic sculpture by Geoffrey Drake-Brockman. It was shortlisted for the 2005 National Sculpture prize and is currently being exhibited at the National Gallery of Australia. Floribots incorporates a JED 573 microprocessor board with buffered I
2C daughterboard and RTC along with sixteen 212 I2C FET output boards. It runs a compiled basic control program and perceives the outside would via eight passive infrared sensors.

Geoffrey Drake-Brockman said "I was looking for a solution to control my electromechanical sculpture which required 128 separate channels of FET output.  I wanted to mount all components inside the sculpture so the system would be fully embedded.  After a long search I was delighted to find JED Microprocessors in Victoria. JED had exactly the right set of products for my application and the solution was less expensive that any of the other alternatives I had explored and had the advantage of a simple bus connection between satellite control modules. A huge bonus while developing my application was the ability to call JED and get informed helpful technical support, often from the person who laid out the board or wrote the test code (or both). This is so much better than dealing with an imported product with little or no support locally. Thank you to Luke and Ed at JED Micro!"


AVR-ISP mkII, In-System Programmer for all AVR microprocessors, in stock, $A75 + GST

The AVR In-System Programmer is used for field upgrades of existing products using the Atmel AVR Architecture. The In-System Programmer is based on the STK500 Hardware and Software. It supports all in-System Programmable AVR devices. It is supported by all AVR compilers (CodeVision, Imagecraft C, BASCOM, AVR Studio). Because it runs from the PC USB port, it avoids problems with printer port modes (ECC, Std, etc) and operates under all PC operating systems with USB support.

It is supplied with a 6-pin programming cable, so is suitable for all the recent JED boards and modules shown above.

(Because a 10-pin cable header is not provided, there is a problem in interfacing to older boards with the 10 pin ISP header, or boards like the JED 585, which has a 14-pin conn ector, formed by adding 4 extra pins to the Atmel 10-pin standard. We are quite unhappy that Atmel has dropped the 10-pin support without any warning, and will soon make available an adapter board to convert the 6-pin cable to the 10 and 14 pin standards. Contact JED for availability.

A full data sheet is available for download at: AVR-ISP mkII user guide

Note: The older serial RS232 port AVR-ISP is no longer available. It has been suddenly deleted, without warning by Atmel.

 


AVR assistance from JED

If you are interested in using AVR processors for any project, small or large ... email or call Ed Schoell at eschoel@jedmicro.com.au with your comments or questions. (03 9762 3588)

JED offers a design service for boards or systems based on AVR, Xilinx gate arrays and a range of other electronic hardware and software projects. We have a group of standard circuit and gate array design modules, with matching software drivers developed during our time creating the Little Blue Computer and friends and we have designed a number of custom systems based on AVR using this experience.
