It's been a while since I've posted, I hope everyone is keeping well! I'm trying to retrieve data from a heart rate monitor with Pd using the comport object. Sending a 'G1' followed by a carriage return to the HRM device using a terminal emulator returns something like 32 10 61, where 61 is the current heart rate and 10 is the time passed since I first queried the heart rate. If I try to print this info in Pd ala:
|comport| | |sprintf %c| | |print|
I get something like this:
3 2 1 0 6 1
Obviously this isn't much use to me. The data that is passed from the serial device is an 8 bit value but I've no idea how to parse it correctly. If I don't use sprintf I get the following print out:
print: 51 print: 32 print: 49 print: 48 print: 50 print: 32 print: 48 print: 32 print: 13
Any ideas or suggestions on how to parse the data being returned from the device?

I think you want something like this (for use with Pd-extended)

Try [bytes2any]? hc suggested it to me yesterday on the dataflow chat and it worked like a charm.
