使用DSP软件实现UART功能.一般教科书上提供的UART收发的程序往往是一段采用轮循（Polling）方式完成收发的简单代码。但对于高速的AVR来讲，采用这种方式大大降低了 MUC的效率。在使用AVR时，应根据芯片本身的特点（片内大容量数据存储器RAM，更适合采用高级语言编写系统程序），编写高效可靠的UART收发接口（低层）程序。下 ...

This example provides a description of how to set a communication with the bxCAN
in loopback mode:
- transmit and receive a standard data frame by polling at 100Kbit/S
- transmit and receive an extended data frame with interrupt at 500Kbit/S
- lit some LEDs depending of the program succeed or not ...
学术论文 RS-485 总线的死锁检测与解除
针对RS-485 接口收发电路的特点，讨论RS-485 总线在Polling 和CSMA/CD 通信方式中死锁检测和解除死锁的方法。该方法同样适用于RS-422 接口。

upsd_flash.c
These functions are provided to help you develop your initial code.
They are optimized for speed rather that size. As a result, you will
see very few nested function calls. If speed is not critical, you
can use function calls for common tasks (like dat polling after
writing a byte ...
