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.)

美国fortemedia消回音芯片FM2018SHI控制程序C 代码以及寄存器操作，可兼容FM1188.(American fortemedia echo cancellation chip FM2018SHI control procedures C code as well as register operation, compatible FM1188.)

说明：  SAR ADC driver circitery design

使用51系列单片机（AT89S52）控制LCD（12864）,全菜单化操作控制初始时间输入，并以指针+数字形式或纯数字形式显示当前时间（年月日周时分秒）及温度（±XXX.XXXX），工程需要环境为keil Uvision2，其中包含以下各模块的C语言驱动程序：x5045,8255c,ATM12864,ds1302,ds1820,8键键盘(74LS164控制)(The use of 51 series single-chip microcomputer (AT89S52) control LCD (12864), the entire menu of operational control of the initial time input, and to guide+ Digital form or pure digital form displays the current time (day of week, minutes and seconds) and temperature ( ± XXX.XXXX), works for the needs of the environment keil Uvision2, which includes the following modules of the C language driver: x5045, 8255c, ATM12864, ds1302, ds1820, 8 keys keyboard (74LS164 control))

几种常用AD，DA芯片的处理子程序，包括ADI和TI的几个芯片及锯齿波子程序(Several common AD, DA chip processing subroutine, including several ADI and TI' s chips and sawtooth subroutine)

说明：  两片STM32F103间的硬件iic通信，主机从机均采用硬件IIC配置(The hardware IIC communication between the two STM32F103 chips, and the host and slave computers adopt the hardware IIC configuration)

STC1256xxAD系列MCU实现8路PT100温度巡回检查程序，温度过高或过低报警。(STC1256xxAD Series MCU achieve 8 PT100 temperature roving inspection procedures, high or low temperature alarm.)

基于51单片机的32和弦音乐盒程序，有曲目切换，音量调节，播放时间，步进电机驱动，流水灯等功能，是普通音乐的升级版本，且代码清晰，注释完整，结构合理。(Based on 51 single-chip 32 polyphonic music box procedures, switch tracks, adjust volume, play time, stepper motor drive, water lights and other functions, is an upgraded version of the ordinary music and clear code, comments, integrity, reasonable structure.)

说明：  当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合 启动电机工作；若测得环境温度小于设定温度，则继电器释放， 电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in. Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released. The motor stopped working.)
