将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)

公司开发的自动售货机文档，包括源代码，电路图，用户文档等(development of the company vending machine files, including source code, circuit diagrams, user documentation, etc.)

超声波流量计，在proteus上仿真的模拟程序，用tdc-gp2进行的时差法测量(Ultrasonic flowmeter, the proteus simulation simulation program, transit-time measurement conducted tdc-gp2)

用的是时钟芯片pcf8583，可以正常显示时间,并带有有Proteus仿真，非常形象！，已通过测试。 (Is clock chip pcf8583, can properly display the time, and with Proteus simulation, the very image of , Has been tested.)
