Help

Hi guys, I'm having trouble getting this to work. I followed the instructions as best as I could. Unfortunately I'm not getting any readings. When I click the run button, I'm able to select the port and press start but I do not get any readings. The RED PPG is a flat green light while the IR doesn't register. No SpO2 value is displayed.

I'd be grateful if you could help me as I am inexperienced with such projects.

I downloaded AFE4490_Oximeter/gui/openview_pulseox.zip on Apr 14, and I also couldn't see any readings after I select the port and press start. However, it worked when I change
if( CES_Pkt_Len == 9)
into
if( CES_Pkt_Len == 10)
in openview_pulseox.pde file
The line is in the switch-case block of case CESState_PktLen_Found. It should be somewhere between line 270 and 290.

I looked at the directory AFE4490_Oximeter/gui/openview_pulseox but I didn't see such error. Maybe the developers have fixed the problem in the code in that directory, but the zip file is not up to date.

did you fix this problem or not

[samuelxu91]

No, I didn't. I am new to GitHub. Am I able to modify the files written by other people?

Your mean problem that you did not update your files. protocentral is updated openview_pulseox.pde file
and change it to if( CES_Pkt_Len == 10)
