|PcmDec||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.
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.
