+
+## linux_uart
+linux 的非标 c 串口库,读写 /dev 目录下的串口设备.用于 linux 串口的使用.
+
+库存放在 components/DeviceDriver/party/linux_uart 中,
+
+临时起用(可被 make distclean 清除)
+
+使用 `make menuconfig` 命令开启 Enable DeviceDriver -> compile uart lib
+
+永久起用 (make 的时候自动包含)
+
+在项目中的 config_defaults.mk 文件中添加:
+```
+CONFIG_DEVICE_DRIVER_ENABLED=y
+CONFIG_DEVICE_UART_ENABLED=y
+```
+启用库.
+
+使用例程查看 examples/linux_uart
