Description: 逻辑分析仪
PC发送到单片机的命令共7个字节：
第一字节是触发信号，每bit对应一路信号，1为高电平触发，0为低电平触发；
第二字节是触发有效信号，每bit对应一路信号，1为忽略，0为有效；
第三、四字节是采样时间，对应如下：
2us=0x0402，5us=0x0a02，10us=0x1402，10us=0x2802，50us=0x6402，100us=0xc802，200us=0x3203，500us=0x7d03，1ms=0xfa03，2ms=0x7d04，4ms=0xfa04，8ms=0x7d05，16ms=0xfa05；
第五、六字节是一样的，为预触发：8=0％，7=12.5％，6=25％，5=37.5％，4=50％，3=62.5％，2=75％，1=87.5％
第七字节为模式，0=普通模式；1=外部时钟，上升延；2=外部时钟，下降延；3=外部触发，上升延；4=外部触发，下降延；5=静态模式；6没有查到，不知道是什么；7为测试模式的二进制信号；8为测试模式的AA、55；9为测试模式的清零。 -Logic Analyzer PC sent to the MCU orders were seven byte : the first byte of the trigger signal, every bit signal corresponding way, a trigger for the margin, 0 for low-level trigger; the second byte is effective trigger signal, every bit signal corresponding way, as a neglected, 0 for the effective; Third, the four bytes of sampling time counterparts are as follows : 2us = 0x0402, 5us = 0x0a02, 10us = 0x1402. 10us = 0x2802, 0x6402 = 50us, 100us = 0xc802. 200us = 0x3203, 500us = 0x7d03, 1ms = 0xfa03. PF = 0x7d04, 4ms = 0xfa04, 0x7d05 = 8ms, 0xfa05 = 16ms; Fifth, six byte is the same as that for pre-trigger : 8 = 0%, 7 = 12.5%. 6 = 25%, 5 = 37.5%, 4 = 50%, 3 = 62.5%, 2 = 75%, 1 = 87.5% for the seventh byte mode, the ordinary mode = 0; 1 = external clock, rose extension; 2 = external clock.

Description: MCU主频12MHz，软PWM控制IO模拟。PWM脉宽调节10uS
PWM频率20mS=50Hz, PWM高电平脉宽700uS~2300uS,PWM低电平脉宽19300uS~17700uS
\"零耗时\"并非不耗时。只是没用软件空等待等恼人的函数。
其主要原理是利用低频宽脉冲软PWM信号的“低速”而T2的16位定时器自动装载功能。
T2在每个PWM周期内中断两次。即PWM高电平和PWM低电平各中断1次。
合理应用RCAP2的预装载功能并进行简单的减法运算而轻松完成任务的要求。

基于TLC2543AD转换芯片的探测仪程序
描述:TLC2543AD芯片为串行12位AD转换芯片,10us的转换时间,11路
模拟输入通道,全串行操作
程序功能:将TLC2543芯片转换得到的数据有条件的发送到PC机
附加功能:将采样结果送出到数码管上显示
操作说明:该程序根据N(需要采样的通道数)的值来进行通道采样
从0通道开始,最大为10,不能超过10,否则出错,采集到的数据
保存到以DBUF定义的起始地址单元中,数据位数为12位.发送
按键每按一次,在向串口发送当前显示通道数据的同时,显示将
更新到下一通道数据,直到定义的通道数据全部发送完毕后,显
示数据将回到0通道.
ETK6201 的程序是很值得参考的，ETK6201单芯片数码管按键扫描芯片，比起MAX7219封装更小，稳定度更高，接口简单。希望大家喜欢
