hi every body...
can any one give me schematic of this type of remote key fob?
these remote r contained of:
----------
transistor:
m6
3em
r25
-------
micro:
pic12f629
-------
12v battery(27a)
-------
and so many resistors and capacitors
-------
i did reverse Engineering on these circuit & found out m6 is a voltage regulator,3em & r25 r high Frequence transistor for rf application.
i found out there r 2 radio circuit ,r25 circuit which is connected to pin 4 of 12f629 and 3em circuit which is connected to pin 3 of 12f629.
i cant understand relation between these to circuit.
this is so confusing!
i know these type of circuit managed by tow pin of micro.first pin is names "boost" and second pin is named "pulse".
i have more info about that if any one wants to know.
and there is a interesting way to copying these remote which the main course of this project!
im waiting for your corporation my friends.
