Creating phase difference between two square signals

Projects Programming

hey folks, ive written a code of generating square pulse in arduino mega. Now i want a phase difference of 3us between pin 11 and pin 6. Can anyone tell me?

the mentioned code is given below:

// 4 PWM signal generator using Timer1 and Timer3 on Arduino Mega 2560

void setup() {
pinMode(11, OUTPUT); // output A (PWM) using Timer1
pinMode(12, OUTPUT); // output B (PWM) using Timer1
pinMode(5, OUTPUT); // output C (PWM) using Timer3
pinMode(2, OUTPUT); // output D (PWM) using Timer3
pinMode(6, OUTPUT); // output A (PWM) using Timer4
pinMode(7, OUTPUT); // output B (PWM) using Timer4
pinMode(46, OUTPUT); // output C (PWM) using Timer5
pinMode(45, OUTPUT); // output D (PWM) using Timer5

// Timer1 setup
TCCR1A = 0; // clear Timer1 registers
TCCR1B = 0;
TCNT1 = 0;

// Timer3 setup
TCCR3A = 0; // clear Timer3 registers
TCCR3B = 0;
TCNT3 = 0;

// Timer4 setup
TCCR4A = 0; // clear Timer4 registers
TCCR4B = 0;
TCNT4 = 0;

// Timer5 setup
TCCR5A = 0; // clear Timer5 registers
TCCR5B = 0;
TCNT5 = 0;

// ICR1 and Prescaler sets frequency for Timer1
TCCR1B |= _BV(CS10); // no prescaler for Timer1
ICR1 = 193; // PWM mode counts up and back down for 80 counts (Timer1)

// ICR3 and Prescaler sets frequency for Timer3
TCCR3B |= _BV(CS30); // no prescaler for Timer3
ICR3 = 193; // PWM mode counts up and back down for 80 counts (Timer3)

// ICR4 and Prescaler sets frequency for Timer4
TCCR4B |= _BV(CS40); // no prescaler for Timer4
ICR4 = 193; // PWM mode counts up and back down for 80 counts (Timer4)

// ICR5 and Prescaler sets frequency for Timer5
TCCR5B |= _BV(CS50); // no prescaler for Timer5
ICR5 = 193; // PWM mode counts up and back down for 80 counts (Timer5)

// Pin match and PWM mode setup for Timer1
OCR1A = 101; // Pin 11 match for Timer1
TCCR1A |= _BV(COM1A1) | _BV(COM1A0); // output A set rising/clear falling for Timer1
OCR1B = 92; // Pin 12 match for Timer1
TCCR1A |= _BV(COM1B1); // output B clear rising/set falling for Timer1

// Pin match and PWM mode setup for Timer3
OCR3A = 101; // Pin 5 match for Timer3
TCCR3A |= _BV(COM3A1) | _BV(COM3A0); // output A set rising/clear falling for Timer3
OCR3B = 92; // Pin 2 match for Timer3
TCCR3A |= _BV(COM3B1); // output B clear rising/set falling for Timer3

// Pin match and PWM mode setup for Timer4
OCR4A = 101; // Pin 11 match for Timer4
TCCR4A |= _BV(COM4A1) | _BV(COM4A0); // output A set rising/clear falling for Timer4
OCR4B = 92; // Pin 12 match for Timer4
TCCR4A |= _BV(COM4B1); // output B clear rising/set falling for Timer4

// Pin match and PWM mode setup for Timer5
OCR5A = 101; // Pin 5 match for Timer5
TCCR5A |= _BV(COM5A1) | _BV(COM5A0); // output A set rising/clear falling for Timer5
OCR5B = 92; // Pin 2 match for Timer5
TCCR5A |= _BV(COM5B1); // output B clear rising/set falling for Timer5

// PWM mode with ICR1 and ICR3 Mode 10 setup
TCCR1B |= _BV(WGM13); // Timer1 PWM mode with ICR1 Mode 10
TCCR1A |= _BV(WGM11); // Timer1 WGM13:WGM10 set 1010

TCCR3B |= _BV(WGM33); // Timer3 PWM mode with ICR3 Mode 10
TCCR3A |= _BV(WGM31); // Timer3 WGM33:WGM30 set 1010

// PWM mode with ICR4 and ICR5 Mode 10 setup
TCCR4B |= _BV(WGM43); // Timer4 PWM mode with ICR1 Mode 10
TCCR4A |= _BV(WGM41); // Timer4 WGM13:WGM10 set 1010

TCCR5B |= _BV(WGM53); // Timer5 PWM mode with ICR3 Mode 10
TCCR5A |= _BV(WGM51); // Timer5 WGM33:WGM30 set 1010
}

void loop() {
}

If only what you need is difference between TWO signals - why did you put 4 timers in code?
Help those who will help you - remove everything unnecessary from the code, leave only two timers. And when you will insert new code, use code tags

About the code - prescaler setting should be the last operation of the timer setup procedure because it start the timer immediately. All other parameters have to be set by this time.

You can achieve a phase difference between the timers by starting one of them from non-zero TCNT counter value calculated in accordance with the desired delay.

I moved your topic to an appropriate forum category @sart1.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

i've told between 2 signals because if i get the sol for this i can change the others by myself
