ll(1)YUFAPANDUAN
- 学编译原理时写的一个语法分析程序 分类:C/C++技术交流 一.[目的要求] ① 对输入文法,由程序自动构造FIRST FOLLOW集 ② 对输入文法,由程序自动生成它的LL(1)分析表; ③ 对于给定的输入串,应能判断识别该串是否为给定文法的句型。 二.[题目分析] 该程序可分为如下几步: (1)读入文法 (2)判断正误 (3)若无误,判断是否为LL(1)文法 (4)若是,构造分析表; (5)由总控算法判断输入符
threeADC
- For P16f887 (includes Hardware using Proteus). This is a code reading 3 internal ADC channels. Could be used with accelerometer. Plus it has a dimmer part which can be controlled by the ADC. Maybe not the best out there, but it worked for me.
lexandyacc
- G代码生成,解释,可以对机床进行控制,对各种参数进行设计-G code generation, interpretation, can be controlled machine tools, the design of various parameters
DS1302shiz_DS18B20
- 功能强大的电子时钟电路,可实现实时时间的显示及调整,可受控操作-Powerful electronic clock circuit, enabling real time display and adjustment, can be controlled operation
PWM
- 先产生一个周期和PWM波相同的周期信号,然后给定一个值,如果这个周期信号大于给定值则输出低电平,否则输出高电平所以,通过控制给定值的大小就可以控制Pwm的占空比了-First generating a cycle and the same cycle of the PWM wave signal, and then given a value, the output is low if this periodic signal is greater than a given value, oth
