I’m dealing with a project with title sounds ‘Microcontroller based speed detection of moving object’, I’m intended to used PIC to do this project. I try to use two Infrared (IR) sensor for a distance, one at the beginning of the distance the other at the end of the distance which function as trigger switch to acknowledge the PIC to start counting and stop counting. The data (time or period) collected is manipulate by using speed equation ‘Speed = Distance/Time’ the distance can have any given value (using keypad, the value of distance restrict to certain range due to the limitation of PIC) or my be a fixed the value. And then the result is display on a LCD display.

I already have a sensor in the motor which provides me 1 pulse for every rotation. So I have to measure the time between two pulses (500-0,6 msec) with for example 3 uS loops. My problem is that i need at least an 19 bit register to save this count, how do i do that ? Another problem is the interfacing fo the 7-segment display. I have to divide 20.000.000 by the count of pulses measured to find the RPM. Does anyone have tips to help me solve this problem ? Or does anyone know where to find code for this application ? Thanks a lot in advance !

At the moment I'm trying to make an RPM counter for elektromotors with an PIC16F84 controller.

To get a high accurancy i would have to fill the time between two pulses with 3 uS pulses (3 cycles at 4 MHZ clock). The only problem is my 8 bit register. How can I make an 19 bit register ?? Also an problem: After measuring 16.000.000 must be divided by the 19 bit pulse count and conversed to an 7-segment display. How can i do that ?
