application AVR-Single-Chip-Processors AT90S, ATtiny, ATmega
of ATMEL in practical examples.
The following examples are small applications to test and use these processors practically and to demonstrate their usefulness. All applications were tested, but I cannot guarantee their correct function.

ClockClock
PCM-encoded remote control signals
in a length from 0.8 to 2.2 ms are decoded
using a AT90S2323 on a small test board
and convert it to a analogue voltage of 0 to 5 Volts.
PcmDec PcmDecPcmDec
Pulse generator
generates exact signals of a desired duration and frequency,
times are controlled by input from an ANSI-compatible terminal program
via the SIO of the chip, e.g. on the STK200 board.
