Hi, I've a problem acquiring the acceleration data with my NI PCI-4474 connected with an accelerometer (the OS is OpenSuse 11.3).
The program always detect an overloaded channel on Dev\ai0
/*********************************************/
// DAQmx Read Code
/*********************************************/
DAQmxErrChk (DAQmxReadAnalogF64(taskHandle,1000,10.0,DAQmx_Val_GroupByScanNumber,data,1000,&read,NULL));
if ( overloadDetectionEnabled )
DAQmxErrChk (DAQmxGetReadOverloadedChansExist(taskHandle,&overloaded));
if( read>0 ){
printf("Acquired %d samples. Total %d\r",read,totalRead+=read);
for(int i=0; i< read; i++){
printf("%f\n", data[i]);
}
}
if( overloaded ) {
DAQmxErrChk (DAQmxGetReadOverloadedChans(taskHandle,overloadedChannels,1000));
printf("Overloaded channels: %s\n",overloadedChannels);
}
Restarting the program or powering off the device seems not to solve.
What are the possible causes of this overloaded channel detection?
Do I have to reset the board or change the accelerometer?
