- 查询方式控制灯闪时间间隔的汇编流水灯程序:由高到低,然后由低到高流动,再全暗全亮三次-Query control time interval lights flash lamp process flow of the compilation: high to low, and then from low to high flows, and then the whole light dark three-wide. . .

- 在一定的頻率的方波中,調整高電平和低電平的占空比,即可實?。比如我們用低電平點亮一個 LED燈-In the square wave frequency, the adjustment of high and low duty cycle, you really?. For example, we use LED lights to light a low-level
IWDG
- 本例程测试了独立看门狗的使用。 程序运行时,液晶屏上会显示: STM32F10x DEMO IWDG TEST 通过使用SysTick中断按照250ms周期性更新IWDG计数器,每次更新的时候L1闪烁一次。使用外部中断7来模拟一次软件失败,按K1将产生一次外部中断7, 因为外部中断7的优先级比EWI优先级高,所以将会导致SysTick中断没有响应,IWDG计数器没有被重载,将出现重置事件,发生重置之后如果按K5来重置程序,L3将被点亮. -This routine tes
s3c2440-PWM
- 利用PWM来驱动蜂鸣器,脉宽从低到高,再从高到低,周而复始。我们还利用4个LED来指示频率的高低,最高时LED全亮,最低时LED全灭。-PWM to drive the buzzer, the pulse width from low to high to low again, and again and again. We also use four LEDs to indicate the level of frequency, the maximum full-bright LED low
