The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

1. 本程序使用一個定時器和任意 2 個 I/O 口模擬一個串行口。 2. 1位起始位,8位數據位,1位停止位。發數據位時先發低位。 3. 支持半雙工通訊。收、發波特率相同。 4. 應把定時器中斷優先級設置為最高級。 5. 本程序每接收一個字節后就把它放到一個隊列緩沖區中(也可使用環行緩沖區), 待緩沖區滿后,將緩沖區中的內容原樣發回。這是為了測試多字節連續收發的 能力和簡化程序。實際應用中應防止緩沖區溢出。 6. 由接收轉換到發送時要先調用 soft_send_enable (); 由發送轉換到接收時要先調用 soft_receive_enable ()。 7. 發送最后一個字節后如果要立刻轉為接收,必須等待最后一個字節后發送完畢 while ( rs_f_TI == 0) // 等待最后一個字節發送完畢

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.
