I'm having a problem driving my car. See how vague that sounds?
State specifically what issues you are having, and upload the broken code, too. 🙂

Oops that must have sounded silly 😕 Ok i've uploaded multiple approaches we tried to use. For some reason the read buffer from the Visa Read won't interact with our calculations 😞 Thanks a many!

Hi nooboist,
please get your VISA read clear: who told you to use a "data bits" property node in your code? It's plain wrong!
You have the TermChar enabled so use VISARead with a sufficient big constant (like "99") as byte count to read!
- There are better ways to build a file path. Use file path functions!
- There are better ways to build an array: use BuildArray!

Hi GerdW,
I have disabled the TermChar and changed the property to read no of bytes at port. Allow me to explain a little the GUI. When I run the code, the information will be saved to a file in which data will be appended to the existing file.
I am getting a PPG waveform signal and I would like to insert a digital filter in the code. However, adding a bandpass filter screws up signal. Without the filter, the code seems to be unable to process the signal as well to achieve a heart beat calculation even though the conversions look like they could work. Attached is the new VI. Any help would be greatly appreciated!
Sincerely
Nooboist
