Hey,
I'm looking to do an LED Tachometer for a student run race car competition. I would like to use PIC's to run the LEDs. What I want to know is if it is possible cause I only have a short period of time to learn PICs and get it working.
The signal coming in would be a frequency that would vary with the RPMs of the engine. As the engine RPMs increase, so does the frequency, and in turn more LEDs are turned on (8 LEDs in a row, increase with RPM). I will have a frequency to voltage converter (0-5V) which will then go into the PIC. The PIC will use a pre-determined formula to compute the RPM from the voltage (i.e. 2.3V is 4000RPM). The voltage would also relate to a Look Up Table (anyother way on a PIC?) that would determine the voltage range for each LED. So if its in a certain voltage range, that would determine the LEDs that should be on.
On top of that, I have a signal coming in that is from the ECU that will determine the best shift point. When the shift point is reached (the RPM number) I want the PIC to flash all the LEDs.
So is this all possible using a PIC, and what should I focus on?
Thanks
