使用avr90can32双串口传输蓝牙数据-Avr90can32 dual-use Bluetooth serial data transmission

AVR串行通信的异步传输模式USART，通过RS232与计算机或者单片机进行串行通信。-AVR serial communication ATM USART, through computer-or single-chip RS232 serial communication.

这是一个单片机应用中编写键盘代码时可以对比参考的，PS2接口的键盘对应的按键码，很实用的，有用到得朋友可以看看。-This is a microcontroller application can write code in contrast to the keyboard reference, PS2 keyboard interface, the corresponding key code, very practical and useful to have a friend take a look at.

单片机与pc机通讯例程的mcu部分，package发送模式，具有数据验证功能,keil c编译-SCM and pc machines mcu part of routine communications, package delivery mode, with data validation features, keil c compiler

这是在KEIL环境下写的CAN源码，具有CANOPEN协议，学习参考的好东西哟！-This is in KEIL environment CAN write source code, with CANOpen agreement, a reference to learn good things yo!

将单片机的IOA0~IOA7分别接按键S1~S8连接到高电平上。此时，如果某个按键被按下，对应的I/O端口就会输入高电平进单片机，即按键S3按下，IOA2会输入高电平进单片机-Will Singlechip IOA0 ~ IOA7 access keys, respectively, S1 ~ S8 is connected to high on. At this point, if a button is pressed, the corresponding I/O port will enter into the high single-chip, that is, S3 button press, IOA2 will enter into single-chip high
