Automatic-traffic-control-system-
自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下：
1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。
2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。
3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))

TM7711
TM7711 是应用于电子秤低频测量的单通道模拟前端。 该器件可以接受直接来自传感器的低电平的
输入信号，然后产生串行的数字输出。利用 Σ-Δ 转换技术实现了 24 位无丢失代码性能。通过选定的输
入信号被送到一个基于模拟调制器的增益可编程专用前端。 片内数字滤波器处理调制器的输出信号， 通
过通信口发命令可调节滤波器的截止点和输出更新速率，从而对数字滤波器的第一个陷波进行编程。
TM7711 只需 2.6~5.5V 单电源供电。TM7711 是全差分模拟输入，带有一个基准输入。
TM7711 是一款用于高精度电子秤系统的理想产品，由于采用特殊的结构确保器件具有极低功耗，
并且内建有掉电模式以减少待机功耗。该芯片还具有集成度高、响应速度快、抗干扰强等优点，可以大
大降低电子秤系统的整机成本，提高整机系统的性能和可靠性。(TM7711 is used in electronic scales measuring the low-frequency single-channel analog front-end. The device can accept a low level directly the sensor
Input signal, and then generates a serial digital output. Use Σ-Δ converter technology to achieve 24-bit no missing code performance. Via the selected output
The signal is fed to an analog modulator based on a dedicated front-end programmable gain. Chip digital filter processing modulator output signal through
Send commands over the communication port can adjust the filter cutoff and output update rate, and thus the first notch digital filter can be programmed.
TM7711 only 2.6 ~ 5.5V single power supply. TM7711 is a fully differential analog input with a reference input.
TM7711 is an ideal product for high-precision electronic scale systems, the use of a special structure to ensure that the device has a very low power consumption,
And built-in power-down mode to reduce standby power consumption. The chip also features high integra)

jquerypichight
jQuery实现平滑的图片亮度渐变，鼠标移到图片上，可看到渐变效果，很平滑流畅的jQuery特效，代码也是超简洁的，可把此特效应用于图片展示、导航菜单中，制作一个鼠标高亮的菜单也是很不错的效果。(jQuery smooth picture brightness gradient, the mouse over the picture, you can see the gradient effect, very smooth smooth jQuery effects, the code is super simple, this effect can be applied to the picture display, navigation menu, make a mouse high highlighted menu is also very good results.)

STM32_KS103_IIC
0.我使用的是F103VET6，但软件IIC原理都是一样的，改引脚配置后可方便移植
1.连接引脚前，可以只连接VCC和GND查看模块当前地址：模块上的LED指示灯会渐亮，然后就是快闪(1)和慢闪(0)，将值记录下来，用计算器转换一下就是当前的地址值了(0. I use F103VET6, but the principle of software IIC is the same, pin configuration can be easily transplanted.
1. Before connecting pins, you can only connect VCC and GND to view the current address of the module: the LED light on the module will gradually light up, then flash (1) and slow flash (0), record the value, and convert it with a calculator to the current address value.)
