Labview与变频器的485通讯实现代码，包含CRC校验子VI。(The 485 communication code between Labview and frequency converter includes CRC checker VI.)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )

Labview的详细开发指南，包括：双精度数据不适于相等比较（内置函数）；顺序结构是“结构”吗？；到底什么是“节点”；XY GRAPH的输入参数形式 ；整型数据类型和内存映射；状态机的基本概念 ；状态机的基本类型顺序结构 ；状态机的基本类型之标准状态机 ；事件结构中的TIMEOUT进行数据采集合适吗 ；全局变量、移位寄存器和功能型全局变量的性能比较等。(Labview detailed development guidelines, including: double precision data is not suitable for equality comparison (built-in function) sequential structure is " structural" it? In the end what is " node" input parameters of the form XY GRAPH integer data types and memory mapping basic concept of the state machine basic types of sequential structure of the state machine basic types of state machine standard state machine event structure The TIMEOUT data collection suitable for you global variables, shift registers and functional performance comparison of global variables and so on.)

用户自行输入所需要的频率和占空比，得到PWM波(Users input the required frequency and duty cycle to get the PWM wave.)
