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

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.

This Handbook, published under the auspices of the Senior NATO Logisticians’ Conference (SNLC), i s i ntended as a simple guide to logistics i n NATO. It does not attempt to examine current i ssues or provide answers to the problems that logisticians will face, but i t rather aims at i ntroducing them to some of the basic principles, policies, concepts and organisations with which they will work.
