Open jcolbert89 opened 6 years ago

jcolbert89 commented 6 years ago

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_PktLen == 9) into _if( CES_PktLen == 10) in openview_pulseox.pde file The line is in the switch-case block of _case CESState_PktLenFound. 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 commented 6 years ago

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

adelalfusail commented 6 years ago

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)
