西门子仿真编程软件S7-PLCSIM V5.4，用于S7-300/400系列PLC程序的仿真(S7-PLCSIM V5.4 offers the following new features with this release: DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node. Increased number of blocks supported for simulation S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.)

光伏阵列是多片光伏模组的连接，也是更多光伏电池的连接，光伏阵列是最大规模的光伏发电系统。(Photovoltaic array is the connection of multiple photovoltaic modules, and is also the connection of more photovoltaic cells. Photovoltaic array is the largest photovoltaic power generation system.)

很好的opencv入门文档，后续上传其他相关-good opencv entry documents, the follow-up to other relevant Upload

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.

说明：  The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when following the path around a curve. The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle.
