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.

SIO controlled digital clock. Could be synchronized with the time normal DCF77, operated on 77.5 kHz in the VLF band in Germany. Wiring see the Links.	AT90S2313	GIF PDF	Clock	Clock
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.	AT90S2323	PcmDec	PcmDec	PcmDec
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.	AT90S8515	PwgSio	PwgSio	PwgSio
