Dear Olimex Community,

I have recently purchased the following items:

1) Olimex MSP430FG439
2) Olimex MOD-USB-RS232
3) SPO2-CABLE-NELLCOR-SENSOR
4) TI MSP-FET Flash emulator tool

So far I have managed to setup them correctly and the measurements seem fine using PulseOxMonitor.

However, I would like to also have the measurements independently(e.g., in a .csv file), in order to graph them or perform some post-processing on them.

I tried using putty(connected the proper COM port, baud rate, parity bits, flow control etc.) but I am not getting any values.

Could you please advise?

Thank you in advance!

Strange, maybe the putty settings have some problem, try another serial software. Typically you should get some numbers like:

0
255
56
126
93
0
255
49
126
93
0
255
42
...

Are you sure that the PulseOxMonitor is working fine?

I was expecting the values you posted  :(

The values printed on the Olimex board screen seem correct, and so is the output on the PulseOxMonitor gui.

I also used minicom as a serial monitor. Still getting garbage.

Just to be on the safe side, the connection details are:
Baudrate: 115200
Databits: 8
Stopbits: 1
Parity: None
Flow control: None

If you have any Arduino board laying around, use that. My tests today with OLIMEXINO-32U4 went pretty smooth. I used the code and instructions here: https://www.olimex.com/Products/Modules/Biofeedback/MOD-PULSE/resources/MOD-PULSE-example.zip

Here are two pictures one showing my hardware setup and the other the software readings:

It is working perfectly now  ;)
