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>

=== 26pin 的 UART 测试 test ===1) In Android 中默认只打开了 default, the UART0 一个串口，UART0 在 serial port is only opened. The position of UART0 at 26pin 的位置如下图所示， 对应的设备节点是'''is shown in the figure below. The corresponding device node is/dev/ttyS0'''ttys0<br><br>

2) 首先点击 wiringOP 图标打开 wiringOP APPFirst click the WiringOP icon to open the Wiringop App<br><br>

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

4) The serial test interface of the APP 的串口测试界面如下图所示is shown in the figure below<br><br>

5) 接着在编辑框中输入想要设置的波特率，然后点击 Then enter the baud rate you want to set in the editing box, and then click the '''OPEN''' 按钮打开button to open the '''/dev/ttyS0''' 节点，打开成功后，node. After successful, the '''OPEN''' 按钮变为不可选中状态，button becomes an optional state.The '''CLOSE''' 按钮和 button and the '''SEND''' 按钮变为可选中状态button become an optional state<br><br>

6) 然后使用杜邦线短接 uart0 的 Then use the DuPont line to shorte the RXD 和 and TXD 引脚pin of uart0<br><br>

7) 然后可以在下面的发送编辑框中输入一段字符，点击 Then you can enter a section of characters in the editing box below, click the '''SEND''' 按钮开始发送button to start sending<br><br>

8) 如果一切正常，接收框内会显示已接收到的字符串If everything is normal, the receiving string will be displayed in the receiving box<br><br>

=== 26pin 的 SPI 测试 's PWM test ===1) 由 26pin 接口的原理图可知，Orange Pi 5B 可用的 spi 为 spi4Android only opened '''PWM15''' by default. The corresponding pins are at the position of 26Pin.<br><br>

2) 这里通过 w25q64 模块来测试 SPI 接口，首先在 SPI4 接口接入 w25q64 设备First click theWiringOP icon to open the Wiringop App<br><br>

3) 然后点击 wiringOP 图标打开 wiringOP APPThen click the '''PWM_TEST''' button to enter the PWM test interface at the main interface of WiringOP<br><br>

4) wiringOP APP 的主界面显示如下图所示，点击 SPI_TEST 按钮打开 SPI 的测试界面The corresponding address corresponding to the PWM15 is '''febf0030'''. The right side of PWMCHIP0 is exactly the '''febf0030.pwm'''. If the displayed base address is wrong, please click the drop -down option to select other PWMCHIP until the '''febf0030''' is displayed on the right.<br><br>

5) 然后点击 Then confirm the PWM cycle. The default configuration is '''OPEN50000ns''', and the PWM frequency is '''20KHz'''. You can modify it by yourself.Click on the button to export '''PWM15''' 按钮初始化 SPI<br><br>

6) 然后填充需要发送的字节，比如读取 w25q64 的 ID 信息，在 data[0]中填入地址0x9f，然后点击 '''TRANSFER''' 按钮Then drag the drag below to change the PWM duty ratio, and then check the enable to output PWM<br><br>

8=== 26pin's SPI test ===1) w25q64 模块的 MANUFACTURER ID 为 EFh，Device ID 为 4017h，跟上面读取到的值是对应的（h 代表是 16 进制）From the schematic diagram of the 26pin interface, the SPI available for Orange Pi 5 is spi4<br><br>

 === 26pin 的 PWM 测试 ===12) Android 默认只开启了 '''PWM15'''，对应的引脚在 26pin 的所在位置如下图所示Here is the w25q64 module to test the SPI interface, and first access the w25q64 device at the SPI4 interface.<br><br>
