This is not related to the code, but I've been trying to find an appropriate heart rate monitor with a usb interface with no luck. Is there any chance you can find the one you used initially and provide a link? would be greatly appreciated.

Congratulations. This code works for Windows.
I'm wondering, how hard it would be to port it to Pydroid (for Android)?
What could be used in place of calls to msvcrt and pywinusb.hid?

Dear Danishlav,

I know this is not the right forum. However, I have bought the HRM USB device and did not got the CD with the software. If you still have HRM2101.exe can you please send me the same. Because that device is of no use for me without the software.

Thanks

What about a 24 bit ADC inside the box?

Maybe the 24 bits of the output corresponds to the 3 bytes of the columns:

MSB | | LSB
byte 2 | byte 1 | byte 0
column 4 | column 5 | column 6

This could explain why the values of columns 5 and 6 are changing faster.

You can try the hypothesis using the struct library.
https://docs.python.org/2/library/struct.html

Something like this:

from struct import *
#reorder the bytes in little endian
buffer=struct.pack ('BBBB',data[5], data[4], data[3], 0x00)
#convert 3 bytes to unsigned int
ADCvalue=struct.unpack ('I', buffer)

Then graph all the values.

Hi,

i get this error when i run the script:

Traceback (most recent call last): File "hrm.py", line 178, in <module> raw_test() File "hrm.py", line 141, in raw_test if found_option: UnboundLocalError: local variable 'found_option' referenced before assignment

Any ideas what might be wrong?

Running Python 6.3.4 and installed pywinusb with pip.

Regards.
