Re: can i get code for pic18 with lcd heartrate measurement and body temprature
TCRT5000 can not measure temperature and it would be far from optimal for measuring heart rate, assuming you mean to check reflectivity from blood vessels.
It is an analog device so if you want to experiment, you first need to amplify the detector output, then filter out frequencies above maximum BPM and finally convert the resulting pulses to PIC voltage levels. From there it is nothing more than a frequency counter.
