CPLD程序，程序中实现了PWM波的产生、ADS8364并行高速AD的读写控制，与AVR单片机的通信控制。CPLD以类似外部RAM的方式被AVR读写，AVR单片机只需要向固定的地址写入或者读取即可。

本程序对高速数据采集系统有很好的参考作用，可以以此修改为其他应用场合。-The CPLD program, the program to achieve a PWM wave generation high-speed AD ADS8364 parallel read and write control, and communication control of the AVR microcontroller. CPLD manner similar to the external RAM read and write by the AVR, AVR microcontroller only needs to fixed address to write or read can. The good reference procedures for high-speed data acquisition system, can be used to modify other applications.
