IMPLEMENTASI MIKROKONTROLER SEBAGAI PENCACAH FREKUENSI BERBASIS PENGUKURAN PERIODE ISYARAT MASUKAN
Abstract: One of the main
components from frequency counter is a processor. This processor must have
ability to conduct counting and arithmetical calculation. To get competitive
price, in this research a microcontroller is applied as a processor. This paper
presents design of frequency counter based on microcontroller AT89S51 which has
two independent timers. The input frequency counter is conducted by using
facilities inside microcontroller e.g. T0 and external interruption. Counter
method used in this research is by measuring input signal period. This method
is proven effectively to count frequency especially low frequency. As the
result, the frequency counter has successfully measured frequency from 0.1
until 10 kHz with maximum error 1%. This device is possible to be the next
frequency counter with competitive price.
