把程序写进单片机从而控制电梯的上下,开关门,报警等功能!这个程序简单,使用性强!-procedures written into the MCU control of the elevator up and opening the doors, alarm functions! This simple procedure, the use of strong!
这是一个针对AVR单片机的串口编程,里面有原理图,加上串口源码。针对型号为ATMEGA128的AVR单片机使用。其它的芯片,如果寄存器一样也可套用。-This is a serial port for AVR MCU programming, which has schematic diagram, together with the serial code. ATmega128 model for single-chip using the AVR. Other chips, the same as if the register can also be applied.
蜂鸣器响
改变蜂鸣器的频率,通过改变延时时间
蜂鸣器的时间要是是靠延时来完成的-Buzzer buzzer ring to change the frequency by changing the delay time if the buzzer is the time to be completed by the time delay
用单片机控制电动车的起停,用C语言编程,编译环境是KAIL C ,选用的芯片是PIC芯片。编译很好。-SCM control of electric vehicles with the start-stop, using C language programming, compiler environment is KAIL C, use the chips are PIC chips. Compile good.
