ST套件产生汽车防盗器报警声,本实例的目的是让大家学会用单片机产生声音的方法，学会计算程序所用时间 本实例的功能是能用16F84产生汽车防盗器的报警声，频率分两个0.1s第一个 0.1S频率从1.8K-3.5K匀速增加第二个0.1S频率从3.5K-1.8K匀速减少, 程序复位后,按S2喇叭叫两声,按S3喇叭叫15秒,中途可按S5停止. PIC单片机 烧写时应注意：配置位已经在程序中写明，加载HEX文件时会自动加载，烧写时不用再手动设置配置位。 实验时请注意套件跳线选择；-pic

我在汇编课上完成的一些作业（上机常见习题）和汇编课本上的几个例题，常用的输入输出模块，如： 把压缩存放的BCD码，转换为对应十进制数字ASCII码的程序；编写从键盘键入0至9中任一自然数x，求其立方值；内存中以BUFFER为首地址的缓冲区有10个非压缩型BCD码形式存放的十进制数，它们的值可能是0~9中的任意一个，将这些十进制数顺序显示在屏幕上等等，-I completed classes in the compilation of a number of operations (on the machine common exercises) and the compilation of textbooks on a few examples of commonly used input and output modules, such as: the compressed storage of BCD code, converted to decimal ASCII code corresponding to the procedure prepared from the keyboard type 0-9 in any natural number x, for the cubic value memory to buffer BUFFER headed Address has 10 non-compression type BCD code stored in the form of a decimal number, their value may be 0 ~ 9 any one of these decimal number sequence displayed on the screen, etc.

用传输矩阵法计算一维光子晶体的带结构的程序,用matlab所编,文件解压后,程序写在word文档中,并附有在matlab下画的图,本人感觉非常有用-use of the transfer matrix method one-dimensional photonic crystal with the structure of the program, prepared by Matlab. unpacks the files, procedures written in word document, together with the painting under Matlab plans, I feel very useful

To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. This code serves as an assembly program template. For detailed information, refer to the PIC18F452 datasheet, MPLAB IDE user guide, as well as MPASM user guide on the course web page.

1，消除按键的抖动问题 因为按键在闭合或断开过程中出现一段抖动期，主要由于按键的不稳定性引起的，这时会呈现一串页脉冲，时间的长短和开关的机械特性有关。一般在5ms~10ms之间。为保证CPU对键的一次闭合作一次处理，必须去抖动。在键的稳定闭合或断开时读键的状态。 2，据EICE51原理图编写并调试一个键输入子程序，其功能为判断键盘上有无键输入，若有键入，作去抖动处理后，计算输入键的键号送累加器A。-eliminate jitter button issues as keys or disconnect the closure process for some jitter period, mainly due to the instability of the keys to the cause, then it will result in a bunch of pages pulse, the duration and switches on the mechanical properties. General ~ 10ms between 5ms. To ensure that the CPU in a pair of keys a close cooperation, must go jitter. The key to the stability closed or disconnected when reading the key state. 2, EICE51 schematics prepared and debug a key input subroutine, and its function of determining whether keys on the keyboard input, if typing for to handle jitter, the admission of Bond, Bond sent accumulator A.
