单片机发出pwm波并ADC采样，。。利用pid调节占空比(Microcontroller sends out PWM wave and ADC sampling)

这是全智能充电器的全部代码之VI部分，一个很好很实用的充电器程序。(This is a full-smart charger all the code of the VI part of a good charger is very useful program.)

类似电脑键盘组合按键触发的功能。利用51单片机实现。有两个独立按键，当把两个独立按键都按下后，蜂鸣器发出“滴”的一声后就停。直到松开任一个按键后，才能重新进行下一次的组合按键触发。(Similar to the function of the keyboard combination of keys. The use of 51 single chip microcomputer. There are two independent buttons, when the two independent buttons are pressed, the buzzer issued a drop of sound after the stop. Until after the release of any key, the next combination of keys can be re trigger. )

dac using pwm this is done for the controller tms 2808

矩阵键盘1602液晶显示键值 矩阵键盘定义： * * P1.0-P1.3为列线,P1.4-P1.7为行线 * * 喇叭接P3.7口 矩阵键盘P1口，1602LCD (1602 keyboard matrix liquid crystal display the definition of key matrix keyboard:* * P1.0-P1.3 for the out-line, P1.4-P1.7 for line* * speakers then I P3.7 port P1 keyboard matrix, 1602LCD)

用msp430开发的频率计带1602显示，可测0——99Khz(Msp430 frequency meter with homemade with 1602 display )

说明：  i2c驱动，可用于驱动具有i2c接口的存储芯片(i2c-driven, can be used to drive with a i2c interface memory chips)

实现温度传感功能 使用1602显示屏 52单片机控制(Realization of Temperature Sensing Function Using 1602 Display Screen 52 Single Chip Microcomputer Control)
