POLAR RMCM01 & T31 uncoded strap connected to Arduino UNO

Development Boards Arduino

Hi,

I am trying to include to my project heart rate.

I am using the Polar Heart Rate Module - RMCM01, Polar Uncoded Transmitter – T31, and a Crystal SMD 32.768kHz.

I have made the circuitry according to the schematic on page 8 of http://www.sparkfun.com/datasheets/Wire … RMCM01.pdf

From witch PIN should I take the readings? from HR or FPLS and where should I connect them? on analog or digital sockets on the arduino UNO board?

Also is there any example code to help me go through?

I am not using the Polar Heart Rate Monitor Interface, I am using just the POLAR RMCM01 receiver with a crystal.

Thank you

Hi,

use HR for an unencoded chest strap.

I’d wire it to digital input 2 or 3, and use interrupt processing, as explained in http://arduino.cc/en/Reference/AttachInterrupt

I’d start with the example given on that page and adapt it.

Could you please tell me something more, I do not understand how can I use attachInterrupt function.

I just want the basic code to get the heart rate input…

If you could please tell me something more, I will be grateful

thanks

Do you understand the concept of a hardware interrupt and its associated interupt service routine?
