Ruth I would suggest that you look at the MCASP peripheral feature on the Beaglebone Sitara processor.
See "AM335x Technical Reference Manual", Chapter 22 There are two of them, and each is a multi-channel audio interface. It looks like your AD7761 can be configured to run serial wire per channel, two four channel TDM or one eight channel TDM. Each MCASP can be configured as four channel, one data wire per channel parallel interface, or in TDM mode each can be configured for either four or eight channel 24 or 32 bit serial. So, it seems that one MCASP should be able to deal with the AD7761 ADC, and you would have multiple options as to how to configure the interface, using two MCASP periherals. You would have to make sure that all the wires you would need are pinned out from the Sitara to one of the headers, where you could get at them, as well as there are no conflicts for each of those pins, as to other things you expect the Beaglebone to be doing. You would need to investigate the availability of a configurable driver, or worst case, write your own custom driver. You are talking about streaming a lot of data, so likely only a modest amount of signal processing can be done on the Sitara in real time. --- Graham == -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
