I'm engaging on this project called remote pulse monitoring system and using the pic18f452 and using TCRT1010[iRDA sensor] chip for the sensor control circuit. in summary, my project is to develop a low power consumption and portable measurement device which can provide continuous monitoring photoelectric plethysmography(ppg) of the user. this project will enable the patients to have their initial pulse rate taken at home.
the first part was a low power consumption PPG device with microcontroller. I'm having a problem regarding the coding, on how to convert analog signals to digital. Therefore, I' m looking for some sample reference templates to overcome this problem.
The program should be able to…
1. Read an analogue wave form
2. Has a threshold value to read the analogue wave.
3. Then convert to digital.
4. Then with the digital wave count the number of beats[HIGH]
5. and display it on LCD[in numerical value example: 60/min]
can anyone help???
