This reference design details non-invasive optical plethysmography - pulsoximetry - using the MSP430FG437 microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. A custom LabVIEW GUI has been developed for this application to display the heart signal, heart rate and % SaO2 number. All the necessary files and steps to get this GUI up and running have been provided along with this report.
