error of configuration for PCMCIA on PDA

[edta]

Hello,

I try to create a very simple application with labView. I would like create a application: when the user activate the botton "Lecture" the program read PCMCIA card in loop and save the data in a file. When the user active the botton "stop", the program stop to read the card and exit the application.

When I install my application on the PDa and I "clik" the botton "strat" for starting the reading, I have a error Message: "Read cannot be performed because this version of DAQmx Read does not match the type of channels in the task. Error code: -200525"

software:

LabView 7.1

extension LabView PDA 7.1

DAQmx Base 1.0.1

PDA: PDA IPAQ Compac h5550 HP

PCMCIA: PCMCIA 6062E 16 inputs

Module: DUAL-SLOT HP

I would like read 8 channels in differentiel mode.

Thank you for your help.

You should try to run one of the example VI like:

Cont Acq&Graph Multiple Voltages-Int Clk.vi

Don't forget to configure your AI Channels with the task configuration utility before you build your PDA App.

One other comment your New File VI should not be in your READ LOOP.

I've used the same IPAQ and DAQ card.  If I can help more let me know.

Hello,

I ha ve try to do something more esaier. i ha ve take the example Acq&Graph Voltage-Int Clk.vi for write my application.
When I test my task with the example I have no error message.
Now, i have take the same come and I have change just the control "Measurement" with a control for xrite in a file. And when I test my application I have a error message "Internal software error - Did not receive acknowledge from CFDAQ eeprom Error Code: -223710"

I think I cannot write directly the data in the file. I must transform the array in string but I do not kwon how to proceed. Can you help me?

Thank you

Congrats on on getting your example to work.

The easiest way to write data to file is with the array to spreadsheet string.  In the sting menu pallet.

I'm not at my development computer so I can't look at your example until tomorrow.

Good luck

I hope this example helps.

I'm not sure if the data needed to be transposed before writing it to file so I put the switch in there just in case.

Good luck

Hello,

Do you have a idea why I have a error message when I execute my program on th ePDA? The message error is in my last "post" (I am not sure it is the english word).

Thank you for the exemple. I will change my program when I find to stop the error.

Thank you for your help.

It seem like you need to configure your task to work with your 6062 Daqcard. On the example I gave you I left the task name on the front panel so you can select the correct task. Make sure you rebuild your VI everytime you reconfigure your task list!! The configuration vi should be located somewhere similar to this: "C:\Program Files\National Instruments\LabVIEW 7.1\project\daqmxbaseconfig.vi" Good Luck Eric

Hello,

I have created a second time my task and now I have a new error message : "DAQmx Base Read.vi Attempted to read a sample beyond the final sample acquired. The acquisition has stopped, therefore the sample specified by the combination of position and offset will never be avaible. Error code: -200278". I don't really understand the message and I don't know how change my new code.

Thank you for your help.

As you can see I ran into the same problem your having.

What do you have set for your scan rate and number of samples to read?

I'm going to see if I can find another reference to that error code.

Good Luck
