XRAM as circular buffer

I am using ADuC841. How can i organize the internal 2K XRAM memory as a circular buffer to capture an event?

  • Since in ADuC841 the XRAM is pre-configured in DMA mode including the stop location. I want to make ADC DMA run continously and with respect to an external interrupt I want to capture an event with pre and post-time information. During ADC DMA conversion how can I reconfigure DMA address pointer without affecting the current DMA sequence?

    These are specific details of the particular chip - nothing to to with Keil as such.

    Doesn't the Manufacturer's Documentation (ie, datasheet, etc) tell you that?

    Doesn't the chip Manufacturer provide examples, application notes, etc, to support their chip?

  • Sorry, i made a mistake. I will post on proper forum. Thanks.
