1. moderate wobbling is fine but not too much
2. yes 0 to 25 us
i currently have 77a and 4431. and no i actually did not try it in hardware only used proteus. my prof wants to see the result in pr ... |

You are going to have to do this for anything that requires 'tight' timing, and with the hardware it becomes a 'one time' calculation
could not understand this sentence?
thanks saniat |

1)could not understand what you mean by accuracy
2)PWM 20 khz shift range 0 to 180
3)processor has to do only ADC other than shift
thanks

i have generated two PWM signals and added a phase shift in the 2nd signal. the code works fine. but the problem is that i want to generate 50 us period signal. though i have given the delay in micros ... |

so if generate a power pwm and a standard pwm (both same frequency and duty), by this way i can show a phase shift between 1 power pwm signal and a standard pwm signal. am i right? |

so do i get a 10 us shift from the original signal?when i say the original signal i mean the signal without the 10us delay.
thank you

this is a simple pwm using standard module. how can use the set_timer2(0) to have a 10us delay start a pwm signal?
#include <18F4431.h> ... |

hello,
I am using pic 18f84431. I got this assignment that i have to generate a PWM signal which will start after 10us. Now i understand that i will wait for 10us then set the timer to zero (as setti ... |
