AT24C256是ATMEL公司256kbit串行电可擦的可编程只读存储器，8引脚双排直插式封装，具有结构紧凑、存储容量大等特点，可以在2线总线上并接4片该IC，特别适用于具有高容量数据储存要求的数据采集系统。本文将介绍该IC的工作原理和与单片机的软硬件接口。-ATMEL Corporation AT24C256 is 256kbit serial electrical erasable programmable read-only memory, 8-pin double-line package, has a compact structure, characterized by large storage capacity can be 2-wire bus, and then 4 the IC, is especially suitable for high-capacity data storage requirements of the Data Acquisition System. This article will introduce the working principle of the IC and single-chip hardware and software interface.

这是一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算，而将所有参数全部用整数，运算 到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可大大提高运算速度，根据控制精度的不同要求，当精度要求很 高时，注意保留移位引起的“余数”，做好余数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。-This is a typical PID process, as in the use of SCM control cpu, please slightly simplified, specific PID parameters to be specific targets identified by experiments. As SCM processing speed and ram resource constraints, generally do not use floating-point operations, and will use all the parameters of all integers, and the final calculations to divide one of the Nth 2 data (the equivalent displacement), will count for a similar operation, it will greatly increase the computing speed, control Accuracy of different requirements and high precision, displacement caused reservations to the attention of the "I", which I do several compensation. This procedure is commonly used algorithm pid the basic structure does not include input and output processing.
