Senior Design Project - LCP54608 - Hear the Rhythm

mlm6016 — Mon, 24 Apr 2017 19:19:21 GMT

For our senior design class we created a digital stethoscope using the LPC54608Xpresso board. We took a regular analog stethoscope, cut the tube close to the diaphragm and inserted a lavaliere microphone into the tubing. The microphone plugs into the board's audio input. Using Keil uVision we implemented a low-pass and band-pass filter to decrease noise and emphasize the desired sounds of a heartbeat signal. The LCD shows the heartbeat signal as well as the calculated heart rate. The report is attached which gives a much more detailed explanation. The code for the project can found at https://github.com/mlm6016/Hear_the_Rhythm and a Demo can be seen at www.youtube.com/watch?v=CHKEfmI9dlM.
