Description: 定时器0 实验
F2812 上有3 个 32 位的 CPU 定时器，本程序主要对 CPU 定时器 0 进行操作，
100MS 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“CpuTimer0”文件夹下的“CpuTimer0.PJT”。
（3）重新编译完毕。
（4）点击【File】 【Load Program…】，选择“CpuTimer0”文件夹下的“DEBUG”
中的“CpuTimer0.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0 产生中断时，CCS 就会停在断点处。如下图所示。
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 0 experiment

Description: 一般说法是selling leads 销售信息

这些一般在B2B 网站中出现，可以通过这个寻求客户。-r computer is idle. The application that misbehaved the most was the Linux kernel. However, as of version 2.6.21, the Linux kernel went tickless, and no longer has a fixed 1000Hz timer tick. The result (in theory) is huge power savings because the CPU stays in low power mode for longer periods during system idle. However... there are many things that can ruin the party, both inside the kernel and in userspace. PowerTOP combines various sources of information from the kernel into one convenient screen so that you can see how well your system is doing at saving power, and which components are the biggest problems. PowerTOP has these four basic goals: Show how well your syste

Description: 用到段码液晶屏，一般是用专用驱动芯片如：HT1621等，考虑到，成本、功耗，决定用单片机直接驱动。液晶屏手册建议用1/3偏压，求简单用1/2偏压，实际搭了个实验板试了一下，效果还是不错的。实际可将分压电阻R2-29加大到1M，和用CPU的一个脚来驱动（可关断），进一步减小功耗，现贴出原理图、程序、照片，供有用者参考。
-Used Segment LCD, special driver chip, such as: HT1621, taking into account cost, power consumption, and decided to use the single-chip direct drive. LCD manual recommends 1/3 bias, 1/2 bias the sake of simplicity, the actual take a experimental board tried it, the effect is good. The actual dividing resistor R2-29 increased to 1M, and with a pin to drive the CPU (OFF), and further reduce power consumption, schematics, procedures, Photos were posted, useful for reference.
