Hi, You can easily check for the pin (PB3) value in the ISR and if it is high so it is rising edge. Best Regards, Ahmed

dear Sir i can do this project. I can assure you that if you work with me once, you will always work with me for these kind of projects.

hi, solution change this line MCUCR &= ~(1<<ISC01) | ~(1<<ISC00); // Trigger INT0 on rising edge to MCUCR &= ~(1<<ISC01) | ~(0<<ISC00); // Trigger INT0 on rising edge let me know

buenas, tener delay en el ISR es mala idea, la mejor opción es usar una variable para detectar el cambio y hacer el resto en otra parte del código... incluyendo el filtro para el botón. Puedo solucionar el problema y entregar el código. un saludo, Gabriel

Hi there. Having worked with Atmel AVR controllers quite a lot, I feel like this feature will be quite simple to implement and I will ideally provide the completed program in under a day. Please feel free to contact me for further details about my skills and qualifications. Thank you.

I can do it for you; just need to re-config interrupt , and modified the code Thanks

Try this. This will power on LED when releasing the button, as you specified. Best regards. #define F_CPU 9600000UL #define FALLING 1 #define RISING 2 #include <avr/io.h> #include <util/delay.h> #include <avr/interrupt.h> char edge = FALLING; ISR(PCINT0_vect) { if (edge == FALLING) { edge = RISING; _delay_ms(50); // Remove button debounce MCUCR &= (1<<ISC01) | (1<<ISC00); // Rising edge } else { edge = FALLING; PORTB |= (1<<PB1); _delay_ms(100); PORTB &= ~(1<<PB1); _delay_ms(100); MCUCR &= (1<<ISC01) & ~(1<<ISC00); // Falling edge } } void SystemInit(void) { MCUCR &= (1<<ISC01) & ~(1<<ISC00); // Falling edge //MCUCR &= ~(1<<ISC01) | ~(1<<ISC00); // Trigger INT0 on rising edge PCMSK |= (1<<PCINT3); // pin change mask: listen to portb, pin PB3 GIMSK |= (1<<PCIE); // enable PCINT interrupt sei(); // enable all interrupts } int main(void) { DDRB |= (1<<PB1); DDRB &= ~(1<<PB3); PORTB |= (1<<PB3); //Enable Pushbutton pull-up SystemInit(); while (1) { } }

Hello, We are a team of embedded hardware and software professionals with experience in microcontroller based projects. Would like to know more about the project. Looking forward to work on this project. Please feel free to contact us for any further discussions. Thanks and Regards Techoviz

hello i used some AVR products in my projects and i would like to help you with your task best regards Gehad

I'm working for Active-Semi Company. I have 2 years experiment in embedded software. Please choose me :)

In your schematic button is not placed on INT0. I have working sample for your schem. Any other changes?

Hi, I am experienced embedded systems designer and have been using AVR's for a long time and would love to work on this project. regards,
