Useful modding - a spectrum analyzer + clock. We came across two 5x8 LED matrix, virtually occupying five-inch drive bay, and I decided to make a spectrum analyzer based on their sound.

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

ATMEGA8_ LTC2400 6位半表头程序 LTC2400最高测量电压为5.3V，超过5.3V或反接都会烧掉。 模拟部分供电最好经过7815稳压，最高输入电压不宜超过18V。 模拟电路与数字电路分开供电。 不要使用开关电源或PWM升压、降压电路供电 (ATMEGA8_ LTC2400 6 ½ -digit meter program LTC2400 highest measured voltage is 5.3V, 5.3V or reverse will be burned over. After 7815 some of the best analog power supply voltage, the maximum input voltage should not exceed 18V. Separate analog and digital circuit power supply. Do not use a switching power supply or PWM buck, boost circuitry)

对矩阵键盘的程序编写，详细地讲述了如何扫描键盘的输入！(The matrix keyboard programming, detailed tells the story of how to scan the keyboard input!)

建立一张顺序存储结构的线性表(顺序表)，表中数据元素为整型数，能够存储的最大元素数量为50。在该顺序表上依次完成以下操作： （1）判定线性表是否为空。 （2）依次在顺序表尾部(第n+1位，n位线性表长度)插入数据元素：15、207、36、79、21、97、652、109、66、81，然后输出整张线性表（依次输出所有元素）。 （3）删除第5个元素，然后输出整张线性表。 （4）在线性表的第3位插入数据92，然后输出整张线性表。 （5）在线性表中查找值为79的元素，如果存在输出它是第几位，不存在输出提示信息。 （6）线性表中查找值为31的元素，如果存在输出它是第几位，不存在输出提示信息。 （7）查找线性表中，值为652的元素的前驱元素以及后继元素的值。 (Order to establish a linear table storage structure (order form), the table is an integer number of data elements, the maximum number of elements that can be stored is 50. On the order form in order to complete the following: (1) determine whether a linear table is empty. (2) sequentially in the order form the tail (the n+1 bit, n-bit linear meter length) into the data elements: 15,207,36,79,21,97,652,109,66,81, and then output the entire linear table (in order to output all elements). (3) Delete the first five elements, and then output the entire linear form. The first three insert data (4) line of the table 92, and then output the entire linear form. (5) Find a linear table of elements is 79, if there is it is the first of several output, the output message does not exist. (6) Find a linear table of elements is 31, and if there is it is the first of several output, the output message does not exist. (7) Find a linear table, element 652 is a precursor elements and the va)
