说明：  支持向量机回归(SVR)理论是建立在支持向量机分类问题的基础上的，确Vapnik通过引入不敏感损失函数 ，将SVM分类理论中得到的结果推广，使其可以用于函数回归。(The theory of support vector machine regression (SVR) is based on the classification of support vector machines. Vapnik extends the results of SVM classification theory by introducing insensitive loss function, so that it can be used in functional regression.)

设计并制作出汽车信号灯微机控制系统； 2）所需执行的操作由相应的开关控制，所需控制的信号灯有： 仪表板左/右转向灯、左/右头灯和左/右尾灯及左/右刹车灯共8个灯，其驾驶操作与灯光信号对应关系如下： (1)左/右转弯(合上左/右开关)：仪表板左/右转向灯、左/右头灯、左/右尾灯闪烁。 (2) 紧急开关合上：除左右刹车灯以外，所有灯闪烁。 (3) 刹车(合上刹车开关)：左右刹车灯亮。 (4) 左/右转弯并刹车：仪表板左/右转向灯、左/右头灯、左/右尾灯闪烁，左右刹车灯 亮。 (5) 合上紧急开并关刹车：仪表板灯、头灯、尾灯闪烁，刹车灯亮。 (6) 停靠(合上停靠开关)：头灯、尾灯以20Hz的频率闪烁。 (designs and produces vehicle lights microcomputer control system; 2) the implementation of the operation from the corresponding switch control, the control signals required : the dashboard left/right shift lights, left/right front and left/right rear and left/right brake lights a total of eight lights, driving its operation and light signals corresponding relationships are as follows : (1) Left/right handers (Hopewell on the left/right switch) : the dashboard left/right turn signals, left/right headlight, left/right rear flashing. (2) emergency switch matches : Apart from the brake lights around outside, all lights flashing. (3) brakes (a switch on the brake) : about brake lights. (4) Left/right handers and braking : the dashboard left/right turn signals, left/right)

This I2C library contains the following functionalities: - master/slave communication - timeout in case of bus failure - self recovery after timeout - possibility to write one of 32 bytes slave registers In the archive you can find the hardware schematic, some photos of the working platform, the required libraries and an working example. In the example the master MCU writes 2 bytes to the slave MCU which then sums them together. Then the MCU read the result and print it on the LCD. In case of I2C failure, either a TIMEOUT or FAILURE message will be printed on the LCD depending of which line was break. The MCU uses for both master and slave was PIC16F887. It use internal clock at 8Mhz so no cristal is required.
