Last edited by FenTrac; 4th December at So, I need to write only numbers every second in string on display memory mapped on 0x adress which are divding with 3. How do you get an MCU design to market quickly? FenTrenc member helped me to solve that problem. Timer0 can count maximumprogrwmming I need counter to count to 1 million. What is the frequency the 89C51 is running at?

How reliable is it? I got with code below only to printing all numbers in one second. Or just how you wrote 1 number per second.

See if these changes to the interrupt routine help with the timing. Losses in inductor of a boost converter 9. The interrupt routine posted above is designed to delay 1 second for each “multiple of three” number. Equating complex number interms of the other 6. What is the function of TR1 in this circuit 3. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

It needs to be changed both in main, and in the interrupt routine where it is currently given a value of If so, does it put a logic high programmming the pin when pressed? Choosing IC with EN signal 2.

Synthesized tuning, Part 2: Input port and input programmibg port declaration in top module 2. In the previous even number code, try just changing the line in the timer0 interupt handler: I need 1 number per second, not all.

The time now is Dec 242: It is untested, but has comments on each line. To test for even numbers, bit 0 is always a zero for even binary numbers. What is the purpose of the 1 second delay? How can the power consumption for computing be reduced for energy harvesting? Last edited by FvM; 2nd December at Merged with previous thread. PNP transistor not working 2. Dec 248: CMOS Technology file 1. The previous interrupt routine would have taken 9 seconds to check “a” since it was testing 1 number per second.


Attached below is a file with some ideas to look at.

If there is a switch, what is it’s function? The code change would be in the interrupt routine: Atmel 89c51 programming 6.

Is there a switch attached to PORT0, pin 0? Switcher only start program,nothing else 4. In your example, this would take 3 seconds because 3 of the 9 numbers in “a” are multples of 3. Part and Inventory Search. I must use counter not delay for interrupt Or, is it a “run” switch to only run while being held down continuously? Code C – [ expand ].
