[Other Embeded program] xhcd DL : 0: 由8031内部定时器1按方式1工作，即作为16位定时器使用，每0.1秒钟T1溢出中断一次。P1口的P1.0～P1.7分别接发光二极管的L1～L8。要求编写程序模拟一循环彩灯。彩灯变化花样可自行设计。例程给出的变化花样为：①L1、L2、…L8依次点亮；②L1、L2、…L8依次熄灭；③L1、L2、…L8全亮、全灭。各时序间隔为0.5秒。让发光二极管按以上规律循环显示下去。-By 8031 according to an internal timer means a work, that is, as a 16-bit timers, each of 0.1 seconds, T1 overflow interrupt time. P1 port P1.0 ~ P1.7 were then light-emitting diodes L1 ~ L8. Requested to prepare program to simulate a cycle of lights. Changes in pattern can design their own lantern. Given changes in routine patterns of: ① L1, L2, ... L8 followed by light ② L1, L2, ... L8 turn out ③ L1, L2, ... L8 full bright Quanmie. The timing interval is 0.5 seconds. Let the law of circulation by the above light-emitting diode display down.

[Other Embeded program] 5 DL : 0: 定时器实验：实验得到的结果为，四个8段数码管显示1234，当按下某键盘后，就会产生定时中断，四个8段数码管只会点亮相对应的那个，在一定延时后，四个8段数码管又恢复显示1234。在flash调试时，需要修改RO BASE为0x00000000，其他不用修改，重新编译下载就可运行。注意：由于系统产生中断，程序计数器就会跳到0x18处执行中断服务子程序，所以不能在SDRAM调试。 -Timer experiment: the experimental results for the four 8-segment LED display 1234, when the press of a keyboard, the timer interrupt will be generated, four 8 point digital control will appear that corresponds to a certain delay After four 8 digital tube display resumed 1234. Debug in flash, you need to modify the RO BASE is 0x00000000, the other not modify, recompile download can run. Note: Due to system interrupt, the program counter will jump to 0x18 Department execute the interrupt service routine, it can not debug the SDRAM.

[Other Embeded program] electric-piano DL : 0: This example describes how to implement a scanning keyboard and then from the pressed key generate a corresponding defined sound frequency. Each time a key is pressed the corresponding frequency value is placed into the timer/counter register. When this counter counts to its maximum value an internal interrupt is generated and the interrupt routine is run. At this point the timer/counter register value is reloaded and the counting continues. In this way, by programming different values into the timer/counter register, different values of frequency can be generated. The internal interrupt routine contains code to change the state of the output port and thus generate the required frequency on a corresponding pin and create the desired note. By adding a suitable amplifier and speaker the system is complete. The important point of the software is to use the timer/counter as a counter to control the output frequency. This frequency has to be calculated.
