内容： *红外测试程序，用单片机通过发射管发射38K的调制频率码，由一体化接收并解码由发光管显示。 *正常情况下，由于反射和高灵敏度接收，LED4（P1.3)一直闪烁，可以用黑色纸片完全遮挡接收头使 *之不能接收到发射管的信号，这是LED4熄灭。说明功能性正常 -Content:* IR test program, launched with the microcontroller through the launch tube of the modulation frequency of 38K code, by the integration to receive and decode from the LED display.* Under normal circumstances, due to reflection and high-sensitivity receiver, LED4 (P1.3) has been flickering, you can completely block the black pieces of paper to make* that they are not receiving the first emission control signal is received, it is LED4 out. Note the normal functional

USB主机方式的应用可以参考CH375的资料，与计算机连接的USB设备方式（或自己做U盘）可以参考CH372 的资料。如果是读写U盘并且用量较少或者是系统集成，关心快速入门并且简单易用，那么可以参考半成 -USB host mode the application can reference CH375 information, and computer-connected USB devices (or their own to do U disk) can refer to the information CH372. If it is to read and write U disk and the amount of less or systems integration, care and easy-to-use Quick Start, it can refer to semifinished

实现测试一台计算机的IP地址，是一个很好的测试IP地址的程序啊-Achieve the test of a computer IP address is a good test IP address of the program ah

一个用单片机控制TC35I发短信的例子，同时可以将接收到的UNICODE码转换为HZK16,对初次开发短信的网友会有帮助-TC35i used to control a single-chip message-fat example, at the same time can be received is converted to UNICODE code HZK16, the initial development of the message users will be helpful

各种单片机反汇编工具包，现在用的人少了，但还是有用的东西，想用的就下吧-compilation of various anti-SCM tool kit, now with fewer people, it is still useful things and to use it in the next

看门狗25045的实例。//25045的4根io脚接在同一端口，本例为p1，//请根据实际电路更改引脚定义-watchdog 25,045 examples.// 4 of 25,045 feet io Then in the same port, the cases of p1,// light of the actual circuit-pin definition change

一个硬件的实现程序，有关于炉温控制的 很好用！-procedures, on the temperature control is useful!

这是一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算，而将所有参数全部用整数，运算 到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可大大提高运算速度，根据控制精度的不同要求，当精度要求很 高时，注意保留移位引起的“余数”，做好余数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。-This is a typical PID process, as in the use of SCM control cpu, please slightly simplified, specific PID parameters to be specific targets identified by experiments. As SCM processing speed and ram resource constraints, generally do not use floating-point operations, and will use all the parameters of all integers, and the final calculations to divide one of the Nth 2 data (the equivalent displacement), will count for a similar operation, it will greatly increase the computing speed, control Accuracy of different requirements and high precision, displacement caused reservations to the attention of the "I", which I do several compensation. This procedure is commonly used algorithm pid the basic structure does not include input and output processing.
