通常的汉字显示方式是先根据所需要的汉字提取汉字点阵（如16×16点阵），将点阵文件存入ROM，形成新的汉字编码；而在使用时刚需要先根据新的汉字编码组成语句，再由MCU根据新编码提取相应的点阵进行汉字显示。在这种显示方式中，如果使用的流字数量较大或语句较多时，利用汉字的新编码组成语句将是一件十分繁琐而枯燥的工作。针对这种情况，本文提出了一种十分简单的方式――直接利用PC机的汉字内码作为单片机系统的编码。-Chinese characters are usually displayed in accordance with the need to first extract of the Chinese character dot-matrix (such as 16 × 16 dot matrix), will be deposited into the matrix documents ROM, a new Chinese character encoding while just need to use the Chinese characters according to the new code composed of statements, and then by the MCU according to the new code to extract the corresponding Chinese character dot-matrix display. In this show the way, if you use the word flow statement number of the larger or more, the use of Chinese characters composed of a new coding language will be a very tedious and boring work. In view of this situation, this paper presents a very simple way- direct access to PC-code character encoding as a single-chip microcomputer system.

基于stm32手持示波器   数字示波器是设计、制造和维修电子设备不可或缺的工具。随着科技及市场需求的快速发展，工程师们需要最好的工具，迅速准确地解决面临的测量挑战。作为工程师的眼睛，数字示波器在迎接当前棘手的测量挑战中至关重要。优点1.体积小、重量轻，便于携带，液晶显示器2.可以长期贮存波形，并可以对存储的波形进行放大等多种操作和分析3.特别适合测量单次和低频信号，测量低频信号时没有模拟示波器的闪烁现象

本文介绍了如何用AD识别用户输入的键盘的方法，较之点阵识别有其不可替代的优势；因为如果用4*4的话须消耗8个I/O口，而如果系统有AD功能的话就可能轻松解决了。 单片机8051F330发给ARM然后发给电脑。 其原理就是利用电阻的分压，按键时产生不同的电压，再用中断快速读取电压；然后对其进行编码，通过串口软件EASYARM在个人电脑里显示；经实验观察，效果还可以。 -This article describes how to use AD to identify the user s keyboard input methods, compared with dot-matrix recognition has its irreplaceable advantages because if we use 4* 4, then to be consumed eight I/O port, and if the system function in AD, then on may be easily resolved. Singlechip 8051F330 distributed computer and then distributed to ARM. Its principle is to use the sub-ballast resistor, when keys have different voltage, and then quickly read voltage interruption then encode, through the serial port software EASYARM in the personal computer display by experimental observation, the effect can also be.
