GPIO的翻译

While you're in there, note in passing how the program imports the GPIO base address from xgpio_l. h& this is dynamically updated by EDK if you shuffle around the base address of the peripheral.

在处理代码时，请注意程序如何从xgpio l.h导入GPIO的基地址&如果变动了外部设备的基地址，EDK会自动更新它。

More and more GPIO ( General Purpose Input Output) pins are required in the design because of the diversification of the PDA's function.

随着PDA功能的多样化，对主处理器通用输入输出口的数量也提出了更多的要求，然而主处理器GPIO的数量是有限的。

This design can test the connection of interface with many pins by using only a few GPIO and will be useful for LCM suppliers.

该测试方法使用较少的GPIO口就能实现对较多管脚的接口连通性的检测，具有一定的实用意义。
