I must use counter not delay for interrupt Below is code which i imagine but dont work correctly Pdogramming is the frequency the 89C51 is running at? Is there a switch attached to PORT0, pin 0? If so, does it put a logic high on the pin when pressed?

If there is a switch, what is it’s function? Is it a “start” switch to start checking for even numbers? Or, is it a “run” switch to only run while being held down continuously? What is the purpose of the 1 second delay? Does it write the 89c5 of all the even numbers once per second?

Or, does it write only 1 of the even numbers once per second? Timer0 can count maximumso I need counter to count to 1 million.

So, counter have value Switcher only start program,nothing else 4. Or just how you wrote 1 programmign per second. It is untested, but has comments on each line.

I believe hexadecimal for 50, is C rather than 3C It’s best to have a pull up resistor on PORT0 pin 0, to hold it high and have the switch pull it low when pressed.

To set the pin 0 as an input, write a 1 to it. To test for even numbers, bit 0 is always a zero for even binary numbers.

I got with code below only to printing all numbers in one second.

FenTrenc member helped me to solve that problem. I need 1 number per second, not all. Last edited by FvM; 2nd December at Merged with previous thread. It returns the remainder of division. In the previous even number code, 89c5 just changing the line in the timer0 interupt handler: Last edited by FenTrac; 3rd December at See if these changes to the interrupt routine help with the timing.

It needs to be changed both in main, and in the interrupt routine where it is currently given a value of The interrupt routine posted above 89c511 designed to delay 1 second programmint each “multiple of three” number. In your example, this would take 3 seconds because 3 of the 9 numbers in “a” are multples of 3. The previous interrupt routine would have taken 9 seconds to check “a” since it was testing 1 number per second.

If it is too fast, increase the value of counter until the speed is what you want. The code change would be in the interrupt routine: Last edited by FenTrac; 4th December at Atmel 89c51 programming 6. Part and Inventory Search.
