基于avr atmega16单片机ad，da源代码，并带lcd显示，usart通信-Based on avr atmega16 SCM ad, da source code, and with lcd display, usart Communications

大部分AVR内部带有AD，本节以使用ATMEGA16的内部AD为例，给出AD转换中断程序-Most of the AVR with internal AD in this section to the using ATMEGA16 internal AD, for example, given the AD conversion interrupt routine.
