Description: 定时器 2 实验
F2812 上有3 个 32 位的 CPU 定时器，本程序主要对 CPU 定时器 2 进行操作，
200MS 产生一次中断。使用时，按以下步骤进行：
（1）点击“CCS”，启动Code Composer Studio 开发环境
（2）点击【project】 【Open…】打开“CpuTimer2”文件夹下的“CpuTimer2.PJT”。
（3）重新编译完毕。
（4）点击【File】 【Load Program…】，选择“CpuTimer2”文件夹下的“DEBUG”
中的“CpuTimer2.OUT”文件，点击【打开】。

（5）点击【Debug】 【Run】或左侧快捷键图标，全速运行。在定时器中断子
函数中，我们打上断点，当定时器2 产生中断时，CCS 就会停在断点处。如下图所示。
注意：TIMER0 属于CPU 外部中断，由PIE 管理，而TIMER2 属于CPU 内部中断，由
CPU 直接管理。两者的具体编程方法有差别，请用户注意软件中的细节。
注：如果发现程序不能正确运行或程序跑飞，可点击CCS 中【Debug】 【Reset CPU】，
然后重新Load 程序。如果还是不能正确运行或程序跑飞，可给学习板和仿真器重新上电。-Timer 2 Experimental
F2812 on three 32-bit CPU timer, this program is the main CPU timer 2
200MS generate an interrupt. Use, follow these steps:
(1) click on the "CCS", start the Code Composer Studio development environment
(2) Click the [project] [Open ...] and open the "CpuTimer2 the folder CpuTimer2.PJT".
(3) re-compile is completed.
(4) Click [File] [the Load the Program ...], select "CpuTimer2" folder under the DEBUG

Description: 由于DS18B20是单线操作，所以必须严格遵守它的时序要求才能正常与之建立联系并实现读写操作。
网上见到的多是程序多是在主程序中以延时的方式实现，而且要求关中断，以实现18B20对时序的要求。但是实际应用中，测温操作一般是作为辅助动作，主要任务是通信及数据处理等其他操作，这样一来，如果将DS18B20的程序代码放在主程序中，势必影响其他需要实时处理的中断。
前些天玩到DS18B20，就尝试以51定时中断的方法实现DS18B20时序，在面包板上成功跑了起来。
用的单片机是STC11F16XE，使用外部晶振24MHz。-As DS18B20 is a single operation, so it must be strictly complied with the timing requirements in order to establish contact with them and achieve normal read and write operations. Online programs are mostly seen mostly in the main way to delay implementation, and requires disable interrupts to achieve 18B20 right timing requirements. However, practical applications, operating temperature is generally used as auxiliary action, the main task is communication and data processing and other operations, so that, if the DS18B20 program code on the main program, is bound to affect other needs real-time processing of interrupts. A few days ago to play to the DS18B20, just try to 51 timer interrupt method to achieve DS18B20 timing, success in the bread board ran. SCM is used STC11F16XE, using an external crystal 24MHz.
