I am currently trying to get the SparkFun Pulse sensor module to work with a teensy 3.1.
I am currently just trying to get the demo code working to use as a basis for further development,
The problem I am having is although the code compiles and load onto the board when run the sketch does not appear to be reading from the analogue input, with an value of 0 being output for raw sensor output over the serial port.
When i run the analogue example sketch for the same pin the raw sensor data is reported correctly.
Source code attached,
(edit) - used analogue read to probe input pin directly - sensor value is displayed correctly, but var signal is still staying 0 .
any help greatly appreciated.
