74HC595在数码管上的详细应用和编程方法-74HC595 in the digital control on the detailed application and programming method

本应用笔记描述了一种完全可行且高度灵活的软件应用，使用dsPIC30F 来控制无传感器无刷直流（brushless DC，BLDC）电机。 此软件将dsPIC30F 外设广泛应用于电机控制。所实现的无传感器控制算法特别适用于风扇和泵。-The application notes described a completely feasible and highly flexible software applications to control the use of dsPIC30F Sensorless Brushless DC (brushless DC, BLDC) motor. This software will be widely used in dsPIC30F motor control peripherals. The realization of sensorless control algorithm is particularly applicable to the fan and pump.

芯片PCF8951共有四个A/D输入通道：AD0，AD1，AD2，AD3,分别与四个电位器(R1,R2,R3,R4)连接，用以调节电位器的输出电压。其中AD0通道既可测量电位器输出电压，也可用于测量从J1插座输入的外接电压，须用开关J2加以选择。J4插座提供由PCF8591输出的时钟方波信号。SAA1064驱动四个数码管显示一路AD转换后得到的数据。-PCF8951 chip, there are four A/D input channels: AD0, AD1, AD2, AD3, respectively, with four potentiometers (R1, R2, R3, R4) connected to regulate the output voltage potential. AD0 channel which can be measured potentiometer output voltage can also be used to measure the input from the J1 socket external voltage, to be used to select switch J2. J4 socket output from the PCF8591 clock square wave signal. SAA1064 drivers of four digital display along after AD conversion data.
