图像识别模组由光学镜头、CMOS传感器(SPCA561A)、图像处理芯片(SPCA563A)组成。 SPCA563A分析和处理SPCA561A传过来的图像信号,并得出相应的信息(颜色、形状等等)。此模组接口简单,应用方便,容易与 MCU 结合使用,我们下面将要介绍的 Demo 就是其与SPCE061A结合的例子。 -Image recognition module by the optical lens, CMOS sensor (SPCA561A), image processing chip (SPCA563A) component. SPCA563A analysis and treatment SPCA561A Chuan-up image signal, and came to the corresponding information (color, shape, etc.). This module interface is simple, convenient, easy to used in conjunction with the MCU, we introduce the following to be the Demo is its combination with SPCE061A example.

程序能够实现将十二位的二进制数5V对应fffH变换成一路0~5V的电压。
精度方面:在使用时上下波动范围大约是0~2fH能保证高位寄存器准确;
调试过程中遇到了一系列问题:(1)p0口的使用需接上拉电阻,内部没有带电阻;(2)调试的过程最好使用单步运行,以便于察看寄存器的内容;(3)对系统板不熟悉,一些硬件方面容易出问题,像口连接,电源、地的连接。(4)直流电源使用不准确,内部的各个电源输出是独立的,需要共地。
-procedures to achieve 12 to a binary number 5V counterparts fffH transform all the way into the 0- 5V voltage. Accuracy : the use of fluctuating ranges of 0 ~ 2fH can guarantee accurate high register; debugging process encountered a series of questions : (1) p0 I need to connect to the widening use of resistance, with no internal resistance; (2) the process of commissioning the best use of single-step operation, in order to inspect the contents of Register; (3) The right not familiar with the system board, Some hardware problems are likely to occur, such as connectors, power, and connectivity. (4) DC power supply use of inaccurate, all within the Power output is independent, to the total needs.

在做项目(工程)的时候,我们经常要用到比较多的按键,而且IO 资源紧张,
于是我们就想方设法地在别的模块中节省IO 口,好不容易挤出一两个IO 口,却
发现仍然不够用,实在没办法了就添加一个IC 来扫键。一个IC 虽然价格不高,
但对于大批量生产而且产品利润低的厂家来说,这是一笔不菲的开支!
那,我们能不能想到比较好的扫键方法:用最少的IO 口,扫最多的键?可以吗?-Doing the project (engineering), we often use the relatively large number of keys, and the IO resource constraints, so we are trying to save in another module IO ports, finally out of one or two IO ports, only to find is still not enough there is really no other way to add an IC to sweep on the keys. Although the price of an IC is not high, but low profits, high-volume production and product manufacturers, this is spending a lot of money! That, we can not think of a better scan key method: with a minimum of IO ports, scan Most of the keys? OK?

条码读入CPU
1. 与条码读入器的通讯
1.1 采用标准的UART通讯协议,波特率为9600,没有校验位,一个停止位。
1.2 通讯的过程是单工的,数据流总是从条码读入器到CPU。
1.3 正常的数据传送总是以一个换行符开始,六个数字,以一个回车符结束。
