用计时器实现的精准的延时程序的代码，希望对大家有用，基于LPC2103...

MCB517 I2C源碼。，用於Freescale芯片系列；供需要研究I2c或iic源代碼的同好參考。當初的取得來源已經忘了。This file contains example code to print over the serial  port of the MCB517 MCU and Evaultion Board (EVAL-MCB517QS).    This example will test the I2C function of the MCB517.    This will be done by writing and reading from    a serial A/D & D/A (P8591).     This example will bit bang two general I/O ports for I2C   The example work with communicate at: 9600, 8, N, 1.    This code was tested using the mon-51 connected through COM-1    of the eval board.    CPU Frequency: 11.0592 MHz
