<p>This paper designs a smart card chip reader based on STM32, and gives a block diagram of the overall design of the system. It introduces the design of the peripheral hardware circuit of the main control chip STM32F103CBT6 and the RF processing chip THM3070, and the format of data communication between each part and flow chart. The communication between the host computer and the reader adopts the USB CCID protocol, which supports the USB full-speed communication rate of 12Mbps, improves the interrupt response, and overcomes the shortcomings of the traditional serial port-based readers with low communication speed and poor interrupt response. At the same time, it realizes data interaction with the PC/SC standard PC application and has better versatility</p>

System Programming

The tidal current energy generation system, which works underwater and is interfered by electrical transmission during the process of data communication, has field update requirements but cannot directly use In-System Programming (ISP) to update, so a remote multi-processor updating system is developed based on ISP and CAN bus. This system consists of a shore station host computer, master controller and the slaves. The host computer transmits the HEX file to the master controller via CAN bus, and the master controller updates the appointed slave by ISP. This paper studies retransmission mechanism and ISP process. The system avoids failed update caused by data channel interference through separating the HEX file transmission and the ISP process.

To realize online automatic measuring of total sugar content in chlortetracycline fermenter, we developed an online automatic measuring system based on MSP430 microcomputer. We designed the automatic sampling, filtering and washing of fermented liquid by controlling the I/O of MSP430 and the relay. The data of total sugar content was sampled and processed by MSP430. The data of total sugar content can display clearly and easily on host computer with the RS232 serial port connection between MSP430 and host computer. The software of this system was programed with C language based on IAR for MSP430 environment. The experiment results show that the online automatic measuring system of total sugar content in chlortetracycline fermenter can be met the demand of practical application.

With the release of the standard, digital television terrestrial broadcasting is being gradually extended in many places. In order to speed up the extension and the application, also to evaluate the existing digital television terrestrial broadcasting system, we need a easy-to-use signal analysis and measurement system. The traditional signal measurement method is through the special hardware circuit to realize, but that method is high cost, and the system structure is complex and single function. To improve the flexibility of the system , we realize the system based on virtual instrument technology. In hardware section, this thesis described the block diagram of the system and the introduction of the NI vector signal analyzer. In software part, this thesis described the overall test system based on LabVIEW and the realization of the system features multi-threading, each step of synchronization signals achieved. The image Fig. 3 and Fig. 4 show the result of this system test software system.
