This program demonstrates how to draw on the client area, it also demonstrates how to use the mouse messages. I think the best way to learn programming is programming, so, let s begin our program now.(This program demonstrates how to draw on th e client area, it also demonstrates how to use the mouse messag es.

卡尔曼滤波有用的资料，本人收集的觉得比较靠谱的资料，另外有陀螺仪与加速度融合的卡尔曼代码code在里面！(Calman filter useful information, I collected feel more reliable data, another gyro and acceleration of fusion of the Calman code code on the inside! )

可以通过图片制作自己想要的东西,大家可以自己制作U盘。(You can make what you want through pictures, and you can make your own U disk.)

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.
