The software is designed and configured for evaluation purposes only.  When designing the software, it was configured so that single shot mode is not supported.

The software is designed in LabView and the source code is available if you wish to modify the code for your particular application/needs.

If I remember correctly, the zip with the source code was password protected?

Could you mail me the password to ti@herrhannes.de? What was the link to it again?

And: What can I have done, that I don't get valid values over SPI? If I don't make a mistake, even 16Bit should be enough resolution for the test signal, even without PGA.

The data is sent MSB first, so it does not hurt it, when I cut the last 8 Bits, does it?

As the ECG seems to work, it should not be a problem with my SPI or later bluetooth transmission.

My only change to the MMB0 is, that in my configuration AVDD is 3.0V und DVDD 3.1V, but this should not matter?

Register settings should be correct. 

Now that I have the password: Is there a driver for this usbstyx thing for Windows 7 64Bit?

I have "made" myself a VISA driver with the corresponding NI toolkit, but this was not possible for the usbstyx driver.

We have been updating the software to be compatible with Win7 and finished beta test program last week.  We hope to release the new software within the next couple of weeks.

Would it be possible to grant access to this beta version? At least of the drivers?

I should have finished my project in a couple of weeks, so this could impose some problems. 

Our beta program is finished, so we are not distributing the code any more.  We are working to improve the content, fix any reported issues, and update a couple items (driver stuff included).  So therefore, we would ask that you wait until the final product is released to prevent any known issues from causing problems or having multiple variations of the code running around.

I discovered that my problems do not start until I activate the respiration DEmodulation circuitry (RESP register, bit 7)

Each of the other options let the ADC on channel 1 operate properly.

I suppose this is the wanted behaviour, because of the deactivated demodulation circuitry, but at least it shows that nothing else should be defective.

So I have some questions:

1) I assume that the respiration function should also work in single shot mode. Correct?

2) Do I have to read more than one respiration signal at once? At the moment I have a function which just reads 216bits via SPI and which is called 16 times per second.

3) Do I have to do something with the respiration signal besides just transmitting it. For example averaging it?

4)Does the respiration function need a longer span of time to work after the start than the rest?

Hannes -

For your previous question, the ADS1298R source should be the same as the ADS1298 source - minus a couple bits.  I can certainly link you to the current source if you need it.  The new software to be released soon will cover both ADS1298 and ADS1298R, so this will be just one source when released.

Thank you for your answers.

So you would recommend to let the ADC run in continous mode. But only picking out one sample every 1/16 seconds should be fine?

Besides this I don't have to pay attention to other "traps"?

Sorry for my stupid questions, but I am still a beginner regarding this.
