We are working on pulse oximeter for our final year project.We did the analog processing of the sensor output and we have with us the required waveforms using red and IR LEDs.We donot know how to proceed with the coding part.Can someone please give us a rough algorithm.
Circuit Celar has published 2 articles about an oximeter.
It was the issue 173 and 174 in 2005. The writer is Jeff Bachiochi.
You can find the pdf files with google with the tag bachiochi, oximeter
