文件系统的基本操作程序,与硬件无关,支持FAT12/FAT16/FAT32-File system

1. 本程序使用一个定时器和任意 2 个 I/O 口模拟一个串行口。 2. 1位起始位，8位数据位，1位停止位。发数据位时先发低位。 3. 支持半双工通讯。收、发波特率相同。 4. 应把定时器中断优先级设置为最高级。 5. 本程序每接收一个字节后就把它放到一个队列缓冲区中(也可使用环行缓冲区), 待缓冲区满后，将缓冲区中的内容原样发回。这是为了测试多字节连续收发的 能力和简化程序。实际应用中应防止缓冲区溢出。 6. 由接收转换到发送时要先调用 soft_send_enable ()； 由发送转换到接收时要先调用 soft_receive_enable ()。 7. 发送最后一个字节后如果要立刻转为接收，必须等待最后一个字节后发送完毕 while ( rs_f_TI == 0) // 等待最后一个字节发送完毕-err

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
