GPIO的音标

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。

By measuring the parameter of power equipment with A/ D converter and GPIO interface, the embedded system samples the wanted data.

该监控系统通过A/D转换和GPIO接口测量电源设备参数进行数据采样。
