ADCPro: maximal number of grabbed samples

Other Parts Discussed in Thread: ADCPRO

In my ADS1274EVM-PDK kit I try to sample relatively long time signals with sample frequency of 200SPS in High Resolution mode (both Ch1 and Ch2)

So even in case I put 60000 into the ADCPro Sample number window and initiate the sampling process, pop-ups error window that says

"Maximum points = 1015808".

But I never exceeded this number...

How can I really achieve the maximal 1015808 sample number, still staying in high-resolution (24bit) mode?

    Update:

    It is happening after proceeding a number of previous measurements.

    After closing and restarting computer this problem disappearing.

    But "closing-restarting" procedure itself in my case is harmful for measurement process itself

    I initiate my kit in Win-XP environment , connect to ADS1274EVM from ADCPro installed in Windows 7 Pro 32bit.

    Seems to me we have some bug of program code.

     

    With regards,

    Reuven.

    Hi Reuven, 

    Currently, ADCPro can only be run on Windows XP. You may experience errors such as these using ADCPro with Windows 7. We are in the process of moving ADCPro over to Windows 7.

    Hi Tony!

    Thank you for remind. In our Lab PC we have Win7 Pro - especially to use Virtual PC Windows XP mode also.

    Is it conventional environment for ADCPro?

     

    With regards,

    Reuven.

    Hi Reuven, 

    Sorry for the delay in the response. I have been trying to reproduce this error here in the lab but have been unsuccessful. We have never tested ADCPro on a Windows 7 computer running a Windows XP emulator so I cannot say how/if it will work. We have tested it on a MAC running a Windows XP virtual PC and have not had any issues. Here is one thing that you could try - Open up a test plug in (for example multi-scope) and test to see if ADCPro works in the Emulated environment. If it does, then set the Block size in the Multichannel scope plugin and Data recorder at the top to 60,000 and see if it removes the error. 

    Regards,
