51-IO-port-uart--C

基于ST3088的音频解码MP3，包括按键输入，IR输入程序。(Based on ST3088 audio decoding MP3, including key input, IR input program. )

说明：  单片机STM32103RCT6,GD32F103RCT6,程序管脚都兼容，采集16通道的ADC数据，通过FATFS文件管理系统将数据存储到SD卡。(Stm32103rct6 and gd32f103rct6 are single-chip computers. The program pins are compatible. The ADC data of 16 channels are collected and stored in SD card through FatFs file management system.)

单片机实现直流数控稳压电源,可调电压为0-9.9伏,步进为0.1伏,可以自动扫描键盘以增加或者减少电压(MCU NC Regulators DC power supply with adjustable voltage of 0-9.9 volts, stepping to 0.1 volts, can automatically scan the keyboard to increase or reduce the voltage)

汽车信号灯控制系统的设计 汽车上的信号灯有:转向灯(左前灯、右前灯、左后灯、右后灯，仪表盘上的二 个指 示灯 )及夜间示 宽灯等 。 当汽车转 弯 、刺 车 停 靠时 ，转 向灯 发出不同 的信号 ；夜问 ．则 点 亮示宽 灯。汽 车转弯或停 靠时 ，相应的 信号灯要 发出 闪烁 的灯光 信号 ， 目前 国内广泛 缱 用 电热 式闪光 器产生 闪光信 号 。(Auto Light Control System lights on the car include: turn signal (front left light, right front lamp, left rear lamp, right rear lights, two lights on the instrument panel) and night lights, wide display. When the car turn, stop puncture car, the turn signal send mixed signals nighttime. The width light is lit. Car turns or stops, the corresponding signal to a flashing light signal, the current domestic-type electric flash wide loving generated by the flash signal.)

DS18B20多IO驱动，带有滤波，数据更稳定精确(DS18B20 driver, with filtering, more stable and accurate data)

说明：  惠普打印机 PCL5 语言 命令函数程序代码参考(hp pcl5 printing command reference)

流水灯 能控制LED灯逐次闪烁，并能调控亮灭的时间 等(Water light can control the successive flashing LED lights, and can control the time of light off)

一个变压器保护的程序，是配电变电所内的保护程序(A transformer protection program, is within the power distribution substation protection program)

STC89c51单片看门狗溢出测试，也适用于STC其他系列单片机，不过有可能需要稍作修改(STC89c51 single watchdog overflow test, but also for other STC series microcontroller, but there may need to make some modifications)
