[ARM-PowerPC-ColdFire-MIPS] S3C44B0X例子程序2 DL : 0: 1. beep -- PWM测试为 ADS1.2 下编译的项目, 在sdt2.51的ADW里调试，该程序运行后在57600的超级终端里按PC机键盘的“+”“-” 按键，可以听到BUZZ增大减小的声音。 2. key -- 按键测试为 SDT2.51 下编译的项目, 在sdt2.51的ADW里调试，该程序运行后按FS44B0X上的按键key1 key2 key3 key4 相应的发光二极管亮 3 keyint -- 按键中断测试该项目在SDT2.51下编译调试。主程序是while空循环，中断服务程序对应四个按键做相应的处理，key1 按键点亮D1灯，并在串口打印信息，因为没有加按键去抖动程序，所以，一次按键，产生几次中断。 -1. Beep-- PWM ADS1.2 testing for the project under the Build, in the ADW sdt2.51 Lane debugging, after running the 57,600 in the Super Terminal Lane by PC keyboard "" "-" buttons, Buzz can be increased to reduce heard voices. 2. Key-- SDT2.51 key test for the project under the Build, in the ADW sdt2.51 Lane debugging, after running the program on the button FS44B0X key1 key2 key3 key4 corresponding LED top-three keyint-- interrupted test button in the project under the Build SDT2.51 debugging. While space is the main program cycle, interrupt service routine correspondence four keys handled accordingly. key1 D1 lights lit keys, and Serial Print information, because no buttons to increase jitter, and therefore, a button. several have interrupted.

[ARM-PowerPC-ColdFire-MIPS] Key DL : 0: 在LPC2368下，采用定时器3中断作为键盘扫描时间间隔，因此此键盘扫描函数不需要死循环实现抗抖动延时-In the LPC2368, the use of timer 3 as a keyboard interrupt scanning time interval, so the keyboard scanning function does not need to die to achieve anti-jitter delay cycle

[ARM-PowerPC-ColdFire-MIPS] KEY DL : 0: STM32f103ZET6，通过定时中断实现按键去抖动，是延时方法去抖动的改进。程序中通过定时去抖动，控制LED翻转，是基本模型。在触摸屏按键按键等程序中都可以以此为函数模块。-STM32f103ZET6, realized by the timer interrupt button to jitter, jitter is the delay ways to improve. Program by timing de-jitter, flip control LED, is the basic model. Buttons and other buttons on the touch screen can be programmed as a function of the module.

[ARM-PowerPC-ColdFire-MIPS] stm32_scan_key DL : 0: stm32 下运行的，按键扫描的的程序，有消抖动功能，有按键翻译功能，有初始化定时器功能。稍微改一下你就可以用- Running under the STM32, the key to scan the program, there is jitter function, there is the key translation function, there is the initialization timer function. Just a little change, you can use it.
