-## Configure GPIO
-
-1. Perform the following operations to configure GPIO:
-
-Take GPIO44 as an example.
-```
-$ cd /sys/class/gpio
-
-$ echo 44 | sudo tee export
-```
-You can run the command `ls /sys/class/gpio` to list the GPIO directory, check whether gpio44 appears, and confirm that the export is successful.
-
-:::tip
-The 44 in the command is the sys number, corresponding to GPIO44
-:::
-
-2. Set the direction of GPIO
-
-Run the command ` echo "out" | sudo tee gpio44/direction ` to set the direction of GPIO44 to output.
-
-Run the command ` echo "in" | sudo tee gpio44/direction ` to set the direction of GPIO44 to input.
-
-You can check the set direction by running the command `cat gpio44/direction `.
-
-3. Set the voltage of GPIO44
-
-Run the command `echo "1" | sudo tee gpio44/value ` to set the voltage of GPIO44 to a high level.
-
-Run the command `echo "0" | sudo tee gpio44/value ` to set the voltage of GPIO44 to a low level.
-
-You can view the set value through the command `cat gpio44/value `.

-## 配置GPIO
-
-1. 执行以下操作配置GPIO：
-
-以 GPIO44 为例。
-```
-$ cd /sys/class/gpio
-
-$ echo 44 | sudo tee export
-```
-可以运行命令 `ls /sys/class/gpio`，列出 GPIO 目录，检查是否出现 gpio44，确认导出成功。
-
-:::tip
-命令中的 44 为 sys 编号，对应 GPIO44
-:::
-
-2. 设置 GPIO 的方向
-
-运行命令 ` echo "out" | sudo tee gpio44/direction `，将 GPIO44 方向设置为输出。
-
-运行命令 ` echo "in" | sudo tee gpio44/direction `，将 GPIO44 方向设置为输入。
-
-可以通过运行命令 `cat gpio44/direction `,来查看设置的方向。
-
-3. 设置 GPIO44 的电压 
-
-运行命令 `echo "1" | sudo tee gpio44/value `,将 GPIO44 的电压设置为高电平。
-
-运行命令 `echo "0" | sudo tee gpio44/value `,将 GPIO44 的电压设置为低电平。
-
-可以通过命令 `cat gpio44/value `,来查看设置的值。
