LED（GPIO）测试(LED（GPIO）test)

LED（GPIO）定义(LED（GPIO）definition)

在MY-SAMA5-EK200底板正面有4个LED，详细如下：
there are 4 LEDs on the base board of MY-SAMA5-EK200,details as below:

丝印 (silkscreen)	CPU引脚 (CPU pin)	LED属性 (LED property)	用途 (application)
D12	PE1	default	内核启动后点亮 (brighten after booting of kernel)
D13	PE2	heartbeat	CPU工作时闪烁 (flash when CPU is in working)
D14	PE3	gpio	用户控制输出 (user control output)
D15	PE4	timer	Timer演示 (Timer demonstration)

led-default测试(led-default test)

led-default对应D12。系统启动完成后，该LED默认被点亮，通常可用作供电指示。就是说在用户没有控制该指示灯的情况下，亮表示设备通电（即电源工作正常）。当然，用户也可以控制该指示灯的亮灭，但这时候灯灭与电源是否工作不存在关联。
led-default corresponds with D12. when booting of system is completed,the LED is brightened defaulty,which is ususally ussed as power indicator,in other words,brightenness of the LED represent a switching on of devices on the condition that user doesn't control the LED.Of course,user can control on and off of the LED,in this case,there is not any relation between on/off of the LED and working condition of power source.
控制命令如下：
control command as below:
＃ echo 0 > /sys/class/leds/default/brightness
＃ echo 1 > /sys/class/leds/default/brightness

led-heartbeat

led-heartbeat对应D13。系统启动后，该LED闪烁，该LED的状态可表示CPU的工作状态。闪烁表示CPU工作正常。常亮或常灭表示CPU工作不正常（即可能是CPU不工作了）。
led-heartbeat correspond with D13. after system is booted,the LED flash,so the condition of the LED can represent the working condition of CPU,e.g.flashing means CPU works normally. solid light or always going out means that CPU doesn't work normally(e.g CPU is unworkable)

led-gpio测试(led-gpio test)

led-gpio对应D14。系统启动后，该LED默认保持常灭的状态。进入系统后，我们可通过指令来控制该LED的亮灭。
led-gpio corresponds with D14.after system is booted,the LED is kept defaulty in state of going out,we can control on/off of the LED through commands after entrance of system
该LED使用的CPU引脚为PE3，在系统中表现由/sys/class/leds/gpioE3/目录下相关的文件表示它的属性。
pin of CPU used by the LED is PE3, its property is represented by the relevant files under directory of /sys/class/leds/gpioE3/ in the system
控制指令如下：
controling commands as below:
＃ echo 1 > /sys/class/leds/gpioE3/brightness
＃ echo 0 > /sys/class/leds/gpioE3/brightness

led-timer测试(led-timer test)

led-timer对应D15。这主要演示GPIO作为timer信号。
led-timer corresponds with D15,this mainly demonstrate GPIO as timer signal
在系统中由/sys/class/leds/timer/目录下相关的文件表示它的属性。
its property is represented by the relevant files under directory of /sys/class/leds/timer in the system
我们可能通过设置delay来控制该GPIO高低电平保持的时间。
we can set dealy to control holding time of high/low electrical level of GPIO
控制指令如下：
controling commands as below:
＃ echo 1000 > /sys/class/leds/timer/delay_off
通过delay_off控制低电平保持的时间，1000即1000ms
control holding time of low electrical level via delay_off,1000 means 1000ms
＃ echo 2000 > /sys/class/leds/timer/delay_on
通过delay_on控制低电平保持的时间，2000即2000ms
control holding time of low electrical level via delay_on,2000 means 2000ms
执行上面两条指令后，我们看到的效果是：D15灭1秒后，亮2秒，如此循环。
after execution of the above two commands,the result: 1 second after D15 goes out,then lit for 2 seconds,cycle this way.

串口测试(serial port test)

MY-SAMA5-EK200评估板有6个串口，其中5个为用户串口，1个为调试串口（位于底板正面“P1”位置）。
MY-SAMA5-EK200 evaluation board has 6 serial ports, 5 of them are user serial port, 1 of them is debug serial port(in"P1" on top view of based board)

MPU定义 (definition)	功能实现 (function realization)	Linux设备文件 (Linux device file)	连接位置 (position of connection)
DBGU	调试串口 (debug serial port)	/dev/ttyS0	P1
USART0	RS232	/dev/ttyS1	J27:5,6(RX,TX)
USART1	RS232,RS485	/dev/ttyS2	J26:14,11(RX,TX)
USART2	RS232,RS485	/dev/ttyS3	J26:10,7(RX,TX)
USART3	RS232	/dev/ttyS4	J27:1,2(RX,TX)
UART0	RS232	/dev/ttyS5	J27:3,4(RX,TX)
