MİKRODENETLEYİCİLER İÇİN SIFIR HATALI BİR-SANİYE ZAMANLAMA ALGORİTMALARININ GERÇEKLEŞTİRİLMESİ

This paper presents a novel accurate timer method that can be used for generating regular of zero-error one second period. Time functions have crucial importance in many control systems. This may manifest itself in the measurement of duration, event counting or control of an external physical event for known periods. Microcontrollers have programmable timers which can be used in many tasks, such as generating timing signals, causing interrupts to be generated at specific time intervals, measuring frequency and time intervals, and so on. Timing errors, which can be measured with microseconds in interrupt subroutine that can be, bring about irretrievable results in control applications. The objective of this research is to propose a new algorithm and implementation its application for generating zero-error one-second period with PIC Microcontrollers that uses an interrupt to carry out accurate timing-related operations inside the microcontroller.
