Piezo Buzzer alternative drive method
Buzzer as a microcontroller system is commonly used devices, its application is very wide. Buzzer has two kinds, one is the active buzzer, as long as the addition of 5V can be issued "drop ..." sound, the drive is simple, the program is simple, but the cost is high, in many occasions, especially now The market is a big competition in society, is not the use of active buzzer; the other is a passive buzzer, this is divided into two kinds, one is the piezoelectric buzzer, the structure is extremely simple, cheap, a Is electromagnetic, the structure is more complex, the price is expensive; In fact, no matter what kind of drive is to add a square wave signal to make a sound. In many occasions, the use of passive buzzer.
The general microcontroller uses software delay to generate square waves, occupy relatively large resources, control is not convenient. STC microcontrollers with PCA module can output PWM and programmable frequency, and has a strong push-pull output, you can easily directly drive the passive piezoelectric buzzer. Today, after some research, I finally learned to use STC's PCA module.
