PIC microcotrollers, applications and PIC based frequence counter

This study examined the PIC (PERIPHERAL INTERFACE CONTROLLER) whichdesigned for controling multi functional logic opretaions faster, easier and alsocheaper ways. Also structures and evolution of PIC is told. I examined whichmicrocontroller is more suitable for the new project.Minimal system, hardware, software requarements are all investigated. Iacknowladge the units which writing or erasing programme over PIC. And also theinterfaces used to connect the PIC programmer to PC.The advantages of PIC is examined. And ı underline the critical differances betweenPIC and other chips manifactured by other companies.Lastly; basic knowladge is told about Frequencemeters. As an example ofprogramming PIC, a frequence counter is designed with PIC 16f84. Circuit diagram,schema and the 16f84 hex files are given abot the frequence counter.viii
