CYUSB3014_schmatic

基于单片机STC89C51和74LS164的多功能数字万用表(Based on microcontroller STC89C51 and 74 ls164 multi-function digital multimeter)

使用单片机任意IO口用软件的方法模拟实现异步串行数据传输的方法，并采用多次采样软件方法来增加软件模拟串口通讯的可靠性，在以上基础上，进一步用具有中断功能的IO口来实现数据的接收，从而增加软件模拟方式的实用性和灵活性；(The use of single-chip arbitrary IO port with the method of software simulation method to realize asynchronous serial data transmission, and the reliability of software sampling method to increase the software simulation of serial communication, on the basis of the above, further with interrupt function of IO port to realize the data receiving, thereby increasing the practicability and flexibility of software simulation method;)

空调压缩机变频控制算法，与直流无刷永磁电机相关，与节能相关。(PWM control algorithm of air-conditioner s condenser )
