Problem with SpO2 on 5515EVM

Other Parts Discussed in Thread: TMS320C5515

Hi!

I have a problem with the pulse oximeter FE on 5515EVM. I have a TMDXMDKPO8328 on a 5515EVM. I use a CCS 4.1.3. After reading some post about problems with SpO2 on this board, I could solve the noise on my signal. But now, I have other problem: the percentage of Spo2 and the heart rate isn't showed on the OLED, Its values are 0. However, when I try to see my signal on the Spo2 MDK, I can see the heart rate (but not the %Spo2). What is the problem?? I haven't idea about the source of the problem. I use the demo program.

Thanks!

Hi,

Is this your heart rate 52?? Dont you feel its bit low
and regarding the problem...i havent used the kit. You have to wait for someone who has the kit.
But we are developing a device based of c5515 to study a physiological signal similar to PPG..so if you can be bit more specific about the problem,
I can give a shot

Hi,

Thanks for your interest.

I use TMS320C5515 mother board and SpO2 FE (Rev. 2). I use Nellcor SpO2 adult probe as the sensor. When I run the demo program I can see a red straight line at the display. Even after inserting my finger into the sensor I get the same red line. If I remove the sensor cable, I get the heart rate as 52, SpO2 percentage as 0, and it keeps varying. I am not getting where the problem is. Can you think of some suggestion for me?
