 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Hi Kevin, Yes, I have seen it, I even commented in it. I don't think it is a product that will produce a good function generator, but I was curious to play with it. For the 5 dollar including shipping, it is a toy. But when I get it, and I see same behaviour, and I find a solution (I will try to fix it, that is me, trying to fix things), then I will put that on the forum. And _if_ I get it improved, I will add an output stage (+/-10V). Since 3.3V is not enough. Volhout PicomiteVGA PETSCII ROBOTS |

Excellent :-) I'll be very interested if you can improve it. Regards Kevin. |

@ville56 Yes, at my age I can't afford to lose much more. There won't be anything left :) Looking at it with my scope it appears that CS does go high a couple of clock cycles before data is sent. I am not sure if there is a problem with PicoMite or if it is with the AD9833 needing CS to go high sooner. But I did make a note in my printed manual. The good news is that I can finally play now. It works to put that dummy message in a sub and call it before sending data VY 73, Steve - N7IO |
