Hello,
I've been working on digital stethoscope daughter board. Here are the steps I followed .
Software steps I followed:
1. Download source code available available for digital atethoscope from https://code.google.com/p/c5505-ezdsp/
2. Created a new work space [Working on CCS 4.1 ]
3. File menu -> import -> legacy CCS project -> next-> next->next -> finish
4. Added bios 5_41_02_14 package into the project.
5. Created a target configuration file for C5515 with ezdsp onboard emulator.
5. Project compiled with no error and generated a binary file[.out file].
Hardware steps I followed:
1.Bought a locally available chest piece.
2. Connected chest piece to the microphone available in headphones-with mic using medical grade tube.
3.Connected this to Digital stethoscope daughter board using J8 connector.
Following these steps,the board isn't picking up the signal from stethoscope and shows the reading to be 0BPM. Whats the solution ??
