    Help me moving averaging

    Let me tell you how moving averaging techinque is implemented. First a window on certain no. of samples (in your case -16) is taken and the samples are averaged over this window. Then this window is moved over to the next window ( 2 to 17) and so on. Hope it helps..

    12V to -24V inverting dc /dc power supply

    Re: 12V to -24V I could think of one possible solutions to ur problem. You can use DC-DC conveters for doing this sort of votage level translation. But they are somewhat costly but very effective. Visit the site of micromax for such converters

    Regarding optocouplers..?

    I was reading ur posts on 2 ground issues. Have observed optocoupler circuits wherein the gnds of both the input and o/p ports are isolated. Is this done to reduce noise propating on the ground line. What will happen if both the grounds are shorted? :?:

    Working on I2C serial memory with 8051 controller.

    Slave address happens to be 0A0 and the firmware is sending the right address when observed on the CRO. Added after 1 minutes: The port pins needs to be configured for either open-drain or push-pull. :idea:
