It provides no functionality but is required // for providing support for generating C code for AVR. // //Example // AVRPWM1SetDuty(0,50,40000); //This function will produce PWM signal of 50% duty cycle on OC1A pin and TCNT1 will reset at 40000 instead at 65535. //See also // AVRPWM1Setup // //Authors // Ashish Kamble // if(output_pin>=2) then disp("Error : Invalid input argument ''output_pin'' in AVRPWM1SetDuty function."); end if(duty>100) then disp("Error : Invalid input argument ''duty'' in AVRPWM1SetDuty function."); end if(Top_Value>65535) then disp("Error : Invalid input argument ''Top_Value'' in AVRPWM1Setduty function."); end endfunction
