A simple V-USB data communication example, intend to display the messages transfered by PC via USB port on a text LCD with a ATmega8. AVR firmware is built with WinAVR GCC and software is built with BC++B5.

CH314USB51系列的单片机与PC通讯一般用串口，但笔记本电脑一般都取消了串口，为了开发使用方便，本人特地利用ATMEGA8制作了USB-ISP下载器，使用过程中可根据自己的单片机开发板适当的改变接线-51 Series MCU and serial PC communication for general use, but laptops generally removed serial, in order to develop easy to use, I use ATMEGA8 spe
