PIC BASED SPEED CONTROLLER
This is a PIC16F870 based speed controller for electrical powered
radio controlled vehicles. The circuit is connected to a
standard R/C reciever and is placed between the battery
and the motor.
It will read the length of the pulses from
the reciever and output a pulse with modulated signal to
a MOSFET transistor that will feed the motor with current
from the batteries.
The circuit also include a break that
will short circuit the motor and forces it stop.
The PIC is programmed with the five ICSP programming
connectors on the PCB. I use a JDM PIC programmer for
programming the PIC.

How to use:
Connect the battery to BAT+ and BAT-
Connect the motor to MOT+ and MOT-
Connect the reciever to the three reciever connectors
on the PCB

PIC based speed controller -- 1.asm lists the "include inkl.inc"
but, I can't find "inkl.inc" am I missing something here??
