Wave Form Identifier

[INaPickle]

Please be patient, this is my first PIC project and I have many stumbles/crashes ahead of me.

500KHz to 1MHz FREQUENCY COUNTER & WAVE FORM IDENTIFIER

Please refer to attached schematic (Don’t laugh!!!), I know I need to start using some sort of design software (suggestions welcome).
See posts for problem statement; I’ll not repeat it here.

OK, let me walk you through the thought pattern for the circuit attached:

1.Set a Vref of ~4v on pin 5. This will be linked as a trigger to pin 13 CCP1, telling timer 3 to turn on and off at +4V (following the wave form).

2.Pin 11 RC0, will be used to calculate the frequency and will be linked to timer1.

3.Pin 13 CCP1, is used to compare the waveforms with their pre-determined waveform time values for sin, triangle, and square waves. Uses timer 3.

4.LCD Screen, 4 bit. First line to display the frequency and second line to display the waveform ID.

So, will this work or am I way off base?
I prefer to work with a correct circuit before I attempt the programming learning curve.
Thanks

OK, it doesn't look as though this project will become a reality. What a shame, I felt it was worth the effort. I can't determine if it is the circuit or the program, I even tried to dumb it down and just go for the frequency range reading only, NO luck! If anyone would like to help with any of the circuit or programming stuff just reply, and I'll evaluate it. Thanks

Hi, Pickles

<< I have many stumbles/crashes ahead of me.>> absolutely right !!!

I think you've forgotten an input circuit ...as PIC 0/1 states specs are not exactly the values Mel gave you for shape detect ...

Second problem ... that don't work for a 1:2 input freq range ... need to mesure the freq. before looking for the waveform ...
