hello everyone
i m doing a project on uav(unmanned aerial vehicle) (plane).i m using 8051 to control servos
and 3 phase brush-less dc motor using ESC(speed controller of 20A) using serial communication
through zigbee..
the problem in my code i need to transfer continuously pwm signals for dc motor and whenever i press some key example 'w' the width of pulse is varied and speed of motor increases i have done it and works fine....""if i try to control servo motor at the same time the pulses gets stopped for dc motor..control executes the servo come back again and dc motor signal ""
this is should not happen if i control servo at the same time pulses for dc also should keep on executing ...
please help i have attached code below
