Daq with PocketPC any speed limit ??

[Yaroslav]

Hi ! HELP NEEDED !!!
i need to sample 12 chanels with 16ksamples/s ....
so its something like ... 200,000 ksamles/s ...
and make some Min/Max calculations ...

i want to use it with the PocketPC and the Daq 6024E .. and ofcourse LabView 7 ...
the speet limit of daq .. is 200,000 ks/s .. so its ok ..

but what PocketPC speed i need ??? (200Mhz, 300Mhz, 400Mhz) ... and if its actually possible to sample this speed on the PocketPC aplication ....
anybody tried ???
any body worked near the limits ???

what amount of memory needed ??? 64 mb enought ??

anybody ?? plz ??? 🙂



its too pity to buy and to find that its not working ...

u can answere also to gena_krakadil@mail.ru

200KS/s on the 6024E should work fine on 200Mhz StrongARM and 400Mhz XScale CPUs. 200/300Mhz XScales will probably not be fast enough. You will need to download the 7.0f1 patch for LabVIEW and the PDA module to get this level of performance (and to support multichannel).

Due to various factors from both Windows CE and LabVIEW PDA, using the high-level multichannel acquisition VIs in a default PDA install you should expect to be able to acquire somewhere around 10s of contiguous data at 200KS/s. This can be improved to 50s by various means including a lower-level usage of the DAQ driver code. If you require continuous acquisition, this is achievable but more difficult to program, and may not be able to operate stably at 200KS/s.

If you need more information a
bout said lower-level programming please msg me privately.
