it looks like last night's recording has hit an edge-case.

python cms50dplus.py -s '2015-09-28 22:00:00'  RECORDED /dev/ttyUSB0 "out-`date --iso-8601=seconds`.csv"
Saving recorded data...

Traceback (most recent call last):
  File "cms50dplus.py", line 327, in <module>

  File "cms50dplus.py", line 302, in dumpRecordedData
    for recordedData in oximeter.getRecordedData(starttime):
  File "cms50dplus.py", line 251, in getRecordedData
    raise Exception("Length not divisible by 3!")
Exception: Length not divisible by 3!

I adjusted the error message to show the length
"Length 253 not divisible by 3!"

any ideas whats going on with this?

Hi,
I tried to run this command but got this:

$ ./cms50dplus.py -s "2016-07-13 18:13:32" RECORDED /dev/ttyUSB0 /tmp/test

    raise Exception("No data stream from device!")
Exception: No data stream from device!

I'm not really sure, but could this be due to a newer firmware version of CMS50D+ (version 4.6)?
Has this python script been tested against 4.6 or only older versions?

Br,

I was asked to convert binary dump file from cms50d+ to CSV format and I soon discovered this wonderful project, that helped me a lot. Then I realized, that there is no possibility to read data from a binary file that I got. The firmware version of the device was v5.1, but it seemed compatible with implementations in this code.

I was able to change the data source to file and there's the implementation: szkocot@51e5cdf

I am not sure if can be integrated into this project smartly, but in case someone has a similar case it might help.
It was tested on 6 recordings and 5 of them were successful and one had synchronization issues.

Publish cms50dplus to pypi to make easier installation.

thanks for the script! can the output CSV include the time of day? its difficult to plot otherwise.

Is it possible to control the device via the serial interface? I would like to turn the device on and off, so that the laser is not running all the time (according to the manual, the device should not be worn for extended periods (more than 2 hours))

I've just pushed my project cms50ew to GitHub. It's a python client for Contec CMS50EW pulse oximeters providing both a Qt5-based GUI and a partially curses-based CLI. Would you be interested in collaborating and eventually merging the projects?
