1. 微型开关(SW1)
Intel Edison有一个独立的usb 2.0 OTG 接口,Arduino扩展板上的USB是多路复用的,你需要通过这个微型开关去切换Host模式和设备模式。当这个开关靠标准USB Type A开启时,就会启用Host模式,靠近micro USB Type B开启时,就会启用设备模式。
2. Arduino复位按键(SW1UI1)
这个复位按键用于复位Edison上的Arduino程序,和Arduino控制器上复位按键功能一样,使用他并不会影响edison的运行,仅仅是让上面的Arduino程序重新执行。
3. 电源开关(SW1UI2)
用于更改Edison电源模式的开关,它是通过软件进行配置的。当按下并保持时,
Pressing and holding the power button will cause the Intel Edison Board to power down leaving the IO configuration in its current state. Pressing the button momentarily when the Intel Edison Board is powered down will cause the Intel Edison Board to reboot. If the Intel Edison Board is running, then a momentary press will cause the Intel Edison Board to go into the low power sleep mode. Pressing the button momentarily when the Intel Edison Board is asleep, will bring the Intel Edison Board into full power mode. 按下并保持超过2秒且小于7秒,Intel Edison将进入AP模式。
4. FM按键(SW1UI3)
The FM button, also called as FWR_RCVR, is used to recover an Intel Edison Board that has a corrupted software image. Powering off the Intel Edison Board, then pressing the FM button and then applying power will cause the Intel Edison Board to go to firmware recovery mode. Two recovery modes are available depending on the state of the RM button when the power is applied.
5. RM按键(SW1UI4)
RM指RCVR_MODE,这是被用于
The RM button, also called as RCVR_MODE, is used to recover an Intel Edison Board that has a corrupted software image. During boot, the state of the RM button will cause the Intel Edison Board enter into two different recovery modes. During boot, when the FM button is pressed (high state) and the RM button isn’t pressed (high state), the processor attempts to load the firmware from flash from the location specified in the UMIP header. During boot, if the FM in pressed (high state) and the RM button is pressed (low state), the processor attempts to download from USB Type B port, regardless of the UMIP header.
6. Edison复位按键(SW1UI5)
这是主复位按键,按下并保持4秒,可以重启Edison;按下并保持8秒,会重置Edison相关配置,所有IO都将变为高阻态。
