2) wiringOP APP 的主界面显示如下图所示，然后点击 '''The main interface of the Wiringop app is displayed as shown in the figure below, and then click the GPIO_TEST''' 按钮打开 GPIO测试界面button to open the GPIO test interface<br><br>

3) The GPIO 测试界面如下图所示，左边的两排 '''test interface is shown in the figure below. The two rows of the CheckBox''' 按钮跟 26pin 引脚是一一对应的关系。当勾选 '''button on the left and the 26PIN pin are one -to -one relationship. When checking the CheckBox''' 按钮时，对应的 GPIO 引脚会被设置为 '''button, the corresponding pin will be set to OUT''' 模式，引脚电平设置为高电平；当取消勾选时，GPIO 引脚电平设置为低电平；当点击右边的 '''mode, the pin level settings will be set. For high levels, when the check -up is canceled, the pin level is set to a low level; when clicking the GPIO READALL''' 按钮时，可以获取到 wPi 号、GPIO 模式、引脚电平等信息。button on the right, you can get the WPI, GPIO mode, pin level information, etc.<br><br>

4) 然后点击 '''Then click the GPIO READALL''' 按钮，输出信息如下图所示：button, and the output information is shown in the figure below<br><br>

5) 开发板 26pin 中总共有 16 个 GPIO 口可以使用，下面以 7 号引脚——对应 GPIO 为 GPIO1_C6 ——对应 wPi 序号为 2——为例演示如何设置 GPIO 口的高低电平。首先点击 7 号引脚对应的 '''Taking the high and low level of the GPIO2_D4 as an example, click the CheckBox''' 按钮，当按钮为选中状态时，7 号引脚会设置为高电平，设置完后可以使用万用表测量引脚的电压的数值，如果为 '''button in the figure below. When the button is selected, the GPIO2_D4 is set to a high level. After setting, you can use the value of the voltage of the pins by the multimeter. If it is 3.3v'''，说明设置高电平成功, Explain that setting high -electricity is successful<br><br>

6) 然后点击 '''Then click the GPIO READALL''' 按钮，可以看到当前的 7 号引脚模式为 '''button to see that the pins mode of the current GPIO2_D4 is OUT'''，引脚电平为高电平, and the pin level is high level<br><br>

7) 再次点击下图的 '''Click the CheckBox''' 按钮取消勾选状态，7 号引脚会设置为低电平，设置完后可以使用万用表测量引脚的电压的数值，如果为 '''button in the figure below to cancel the check status. The GPIO2_D4 pin is set to a low level. After setting, you can use the value of the voltage of the multimeter to measure the pins.If it is 0v'''，说明设置低电平成功, the low -power flat is set.<br><br>

8) 然后点击 '''Then click the GPIO READALL''' 按钮，可以看到当前的 7 号引脚模式为 OUT，引脚电平为低电平button to see that the pins mode of the current GPIO2_D4 is OUT, and the pin level is low<br><br>
