In the previous even number code, try just changing the line in the timer0 interupt handler: Does it write the string of all the even numbers once per second?

Distorted Sine output from Transformer 8. Digital multimeter appears to have measured voltages lower than expected. Dec 242: Last edited by FenTrac; 4th December at How reliable is it? See if these changes to the interrupt routine help with the timing.

Is it a “start” switch to start checking for even numbers? Is there a switch attached to PORT0, pin 0?

How do you get an MCU design to market quickly? Attached below is a file with some ideas to look at.

Heat sinks, Part 2: CMOS Technology file 1. Or, does it write only 1 of the even numbers once per second? To test for even numbers, bit 0 is always a zero for even binary numbers. What is the purpose of the 1 second delay? Timer0 can count maximumso I need counter to count to 1 million. The code change would be in the interrupt routine: Or, is it a “run” switch to only run while being held down continuously? kn

PNP transistor not working 2. In your example, this would take 3 seconds because 3 of the 9 numbers in “a” are multples of 3. I got with code below only to printing all numbers in one second. Switcher only start program,nothing else 4. If so, does it put a logic high on the pin when pressed? So, counter have value Merged with previous thread. I believe hexadecimal for 50, is C rather than 3C PV charger battery circuit 4.

I must use counter not delay for interrupt Below is code which i imagine but dont work correctly What is the frequency the 89C51 is running at?

I need 1 number per second, not all.

So, I need to write only numbers every second in string on display memory mapped on 0x adress which are divding with 3. Last edited by FvM; 2nd December at It returns the remainder of division.

FenTrenc member helped me to solve that problem. Losses in inductor of a boost converter 9. It needs to be changed both in main, and in the interrupt routine where it is currently given a value of The previous interrupt routine would have taken 9 seconds to check “a” since it was testing 1 number per second.

The time now is How can the power consumption for computing be reduced for energy harvesting? Progranming it is too fast, increase the value of counter until the speed is what you want.

If there is a switch, what is it’s function?
