New AVR development tool - AVR Dragon

The Atmel ® Corporation this month released a new low cost development tool for AVR ® Microcontrollers - the AVR Dragon.

(AVR, Atmel, 8 bit Microcontrollers)

It supports In-System Programming, High Voltage Serial Programming, Parallel Programming, JTAG Programming.

While this is a welcome addition to the toolset available for development of AVR 8 bit microcontrollers, a couple of issues should be considered.

Audio line level switcher using ATmega32

This was a first attempt at making a solid state switching or multiplexing device for audio signals.

It uses 4051 chips for the actual multiplexing of signals, As such it can switch 2 banks of 8, or using th INH pin of the 4051, and connecting the inputs as common, 1 bank of 16 channels.

Socket for 8 pin SOIC AVR to suit STK500 programming board

Should an 8 pin AVR device in the SOIC package require programming other than ISP programming, it is necessary to connect directly to the STK500 board. This situation could arise due to accidental programming of various fuses.

ATMega8 ADC resolution increase by oversampling

For applications requiring lower sampling rates but higher resolution, Atmel note AVR121 describes methods for oversampling and decimation. The sample application uses a ATMega16, but the code is easily adapted to an ATMega8.
