Hello,

Perhaps am I paranoiac,

but is it possible that a PIC programmer records data in addition to your
program without you it knowing?

More seriously:
look up the programming commands for each PIC chip, there are unaccounted for
codes, do these give uChip override of CP ?
I asked this of uChip about 4-5 years ago re the 16c84 and was ignored.

Thank for yours many reply.

I have test this circuit for read the "W" output alternator:



   input  >------ R 2,2K-------------*-------------- R 10K ------    >  to
pin RB6 ( input  pic 16F84 )
                                            I
                                        I
                                        I
                                 Zener  5,1v
                                        I
                                        I
                                        I
                                    0v

Results:
Truck at   600T/mn  pulse = 2,2 ms  F= 227 Hz
Truck at   700T/mn  pulse = 2,0 ms  F= 250 Hz
Truck at 2550T/mn   pulse = 0,7 ms  F= 715 Hz


My problem :
Some parasites on the "W" output alternator degrade the signal end the result
is wrong.

How it's possible to perfect the electronique circuit ?

Thank for your help

Jacky
