GPIO控制 ======== :: >作者：武壮壮（硬件） 汪远（软件） 更新时间：2020年8月8日 关键字：gpio 概述 ---- Air724UG模块引脚共支持29个GPIO，部分引脚上电前后状态不同，如使用这些管脚，需根据实际情况使用。 管脚定义： ---------- :: VLCD、VMMC、VSIM1相关引脚电压域会根据外部硬件，其内部自动调整其输出电压，为1.8V/3V/3.3V At reset, after reset 都默认指的就是function 0功能的状态（即GPIO 配置还没生效前的状态） GPIO0~5 电源域默认关闭，所以at reset, after reset状态都是L GPIO29~31电源域默认关闭，所以at reset, after reset状态都是L +---+---+---+------+---+---+---+---+---+---+-------+---+-------+---+-------+----+ | | | | Pin | | | | | | | Fun | | Fun | | Fun | | | | | | S | | | | | | | ction | | ction | | ction | | | |
