Basic application example of STC89C52RC timer

The timer/counter of the 51 microcontroller is a programmable component. Its working mode, initial count value and start-stop operation should be initialized before the timer/counter works, that is, write the corresponding control word to the corresponding register. There are two timers T0 and T1 inside the standard 51 single-chip microcomputer. The special function registers related […]

What role does crystal oscillator play in single chip microcomputer system

Crystal oscillators, also known as crystal oscillators, are usually divided into two types: active crystal oscillators and passive crystal oscillators. Passive crystal oscillators are generally called crystals, while active oscillators are called oscillators. From the name of the crystal oscillator, it can be known that it is destined to oscillate constantly. The single-chip microcomputer is […]
