FreeRTOS，這個比 Real Time Linux 和 eCos 更小的實時操作系統，并且你也不用為這兩個大的操作系統弄得頭大了。FreeRTOS是一個非常小的實時操作系統，它包含有一個實時的內核及一個內核調制程序。它支持的單片機有 Philips ARM7, TI MSP430, Renesas (Hitachi) H8/S, Atmel AVR, Motorola/Freescale HCS12, Motorola/Freescale ColdFire, 及其他8051的單片機

C++完美演繹 經典算法 如 /* 頭文件：my_Include.h */ #include <stdio.h> /* 展開C語言的內建函數指令 */ #define PI 3.1415926 /* 宏常量，在稍后章節再詳解 */ #define circle(radius) (PI*radius*radius) /* 宏函數，圓的面積 */ /* 將比較數值大小的函數寫在自編include文件內 */ int show_big_or_small (int a,int b,int c) { int tmp if (a>b) { tmp = a a = b b = tmp } if (b>c) { tmp = b b = c c = tmp } if (a>b) { tmp = a a = b b = tmp } printf("由小至大排序之后的結果:%d %d %d\n", a, b, c) } 程序執行結果： 由小至大排序之后的結果:1 2 3 可將內建函數的include文件展開在自編的include文件中 圓圈的面積是=201.0619264

能給發家提供這個好東西不容易，希望大家能多多學習，不要辜負了。 uC/GUI是uC/OS-II配套的專用圖形界面。這可不是開源軟件，也不象uC/OS-II一樣可以免費下載，這個是非常昂貴的軟件。所以大家拿到后，不要聲張，偷著樂吧 ^_^

CBC下寫的串口編程，API函數實例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.

解決時鐘問題，acm競賽題 A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15. Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand back to 0.
