#106935 - we can think of something Responding to: ???'s previous message |
The funny thing is that it relys on a quirk in the first pics 16C54.
I think we can do better with fast 8052s or dspics. The good news it saved me from doing the square wave oscillator then do the switched capacitor filter to get the sin wave out. I don't need the modulation stuff mentioned in the article, this helps a bit with speed. mahmood |
