pradeep.biomed -urgent need of timer coding in pic

[pradeep]

hi ,
i'm doing my final year project regarding Automatic blood pressure measurement . we did analog part and now we are working with PIC(16F877A) for interfacing with PC to display in Visual Basic.

we got coding for ADC +USART +ASCii and we coding for timer.Our project is based on timing which is used to caliberate pressure. we were able to send digital values in hyperterminal.

Our Systole voltage is 1.6V
Mean Arterial Pressure is 3.2V
Diastole voltage is 2V

The Equivalent digital value is seen in hyperterminal . timer is used to find at what time these voltage appear . Based on timing we can able caliberate pressure .


I need help for this from any member of the group. plz send the coding as soon as possible
