1.该产品是一个民用高速脱水机，机器最大容量为5公斤。 2.全自动波轮洗衣机的脱水转速为：8000-1000rpm。当脱水转速到达3200rpm时，化纤类衣物在夏天几乎可以直接穿了――非常干了。 3.该产品原来是德国的，他们采用交流感应电动机，我们无法实现――因为没有解决刹车的问题。高速下刹车的解决需要好的材料选择以及精确的设计。BLDC的刹车就好办了。 4.我的设计非常精简――1片MEGA48，6只75NF75，1只20A的桥――详细见电子元器件清单，成本只有不足30元。 5.请务必采用环形变压器！因为借助它的压降来分析的 6.同时提供的PCB以及电子元器件清单都是真实的，可以直接用（PCB上低端驱动中的一个三极管需要改为PNP！）-1. The product is a commercial high-speed dehydration machine, the machine maximum capacity of 5 kg. 2. Automatic Washing Machine for the dehydration speed :8000-1000rpm. When the dehydration speed reaches 3200rpm, the chemical fiber clothing to wear in the summer is almost directly- and very dry. 3. The product was originally German, and they use AC induction motor, we are unable to achieve- because there is no brake to solve the problem. High speed brakes to resolve the need for good material selection and precision design. BLDC brake on the easier to handle. 4. My design is very streamlined- 1 Pian MEGA48, 6 Zhi 75NF75, 1 Zhi 20A of the bridge- see

ARM处理器软中断处理。a_swi.s文件是最开始处理的SWI句柄,用ARM汇编指令编写。c_swi.c文件是在执行a_swi.s文件之后调用执行的C语言SWI句柄。 -ARM processor soft interrupt handling. a_swi.s document is the beginning of the SWI handler deal with the preparation of ARM compilation directives. c_swi.c document is in the implementation of a_swi.s document called the C language implementation of SWI handler.
