18b20测温c51程序，由89S52作为主控芯片(18b20 c51 temperature process, from the master control chip 89S52)

说明：  这段程序是用在一款七彩灯红外遥控解码程序里,单片机使用PIC12F629,软件模拟三路PWM输出驱动红绿蓝LED分八组共24个LED,实现单LED渐明渐暗,两LED一明一暗,七彩等九种花样.有断电记忆功能(This procedure is used in a colorful light infrared remote control decoding procedure, the single-chip using the PIC12F629, the software simulation of three-way PWM RGB LED output driver in eight groups of 24 LED, single LED gradually dimming out, two LED Kazuaki a dark, colorful patterns, such as nine. have power memory function)

将滑动变阻器的值通过AD口将其ADC值转换为欧姆并显示在数码管上(The value of the sliding rheostat is converted to Ohm through the AD port and is displayed on the digital tube through the ADC port)

STM32单片机的PID算法实例，通过PID算法控制STM32的PWM输出，反馈量是PWM低通滤波后得到的AD(STM32 microcontroller PID algorithm instance, through the STM32 PID algorithm to control the PWM output, PWM amount of feedback is obtained after low-pass filter AD)

该程序为大家提供定时器程序例程。给大家一个参考，来实现简单的定时功能(This program provides you with timer routines. Give you a reference to achieve a simple timing function)

说明：  对AD9959英文数据手册进行了详尽的翻译，并标注出了一些很重要的功能、结构，能加快初学者入门速度，提高编程效率。(This paper makes a detailed translation of AD9959 English data book, and marks out some very important functions and structures, which can speed up the beginners' entry speed and improve the programming efficiency.)

实时显示水的温度，流量，还能根据比例设置水费。具有锁定功能(Real-time display of water temperature, flow, but also according to the proportion of water charges. With locking function)

奥利生的一款单片机数据手册，和PIC16F887兼容！可使用汇编，c语言！(Orly students a microcontroller data sheet and PIC16F887 compatible! Can use assembler, c language!)

学习C8051系列单片机的必备书籍，十分好用(Learn C8051 Series MCU essential books, very easy to use)
