Guys
What will be a reliable yet cheap way to get 38 or 40Khz ~50% duty cycle 5v p.p freq ?
Obviously this will be used to modulate serial transmission so I can use a TSOP1738/40 to demodulate the stuff at remote end.
Will a 555/556 based idea be stable enough ?
Can a AT89C52/2051 do it well enough ?
I would rather not use hard to get / expensive stuff to just generate 38/40kHz..
Hope I make sense
