GPIO ==== 概述 ---- Air720UG/UH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。 使用说明： ~~~~~~~~~~ :: 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 +----+---+---------+----+---+-----+-----+-----+---+---+---+---+---+---+----+---+ | | | | P | | | | | | | F | | F | | Fu | | | | |

pio.OUTPUT， pio.INT pin1 第一个管脚 pin2(可选) 第二个管脚 pinn(可选) 第n个管脚 ========== =============================================== - 返回值 无 pio.pin.setval() ~~~~~~~~~~~~~~~~ 设置管脚的值 - 语法 ``pio.pin.setval(value,pin1,pin2,...,pinn)`` - 参数 ========== ================ 参数 释义 ========== ================ value 管脚值，可选0或1 pin1 第一个管脚 pin2(可选) 第二个管脚 pinn(可选) 第n个管脚 ========== ================ - 返回值 无 pio.pin.getval() ~~~~~~~~~~~~~~~~ 读取管脚的值 - 语法 ``val1, val2, ..., valn = pio.pin.getval( pin1, pin2, ..., pinn )`` - 参数 ========== ========== 参数 释义 ========== ========== pin1 第一个管脚 pin2(可选) 第二个管脚 pinn(可选) 第n个管脚 ========== ========== - 返回值 number类型，0表示低电平，1表示高电平 pio.pin.sethigh() ~~~~~~~~~~~~~~~~~ 设置管脚为高电平(1) - 语法 ``pio.pin.sethigh(pin1,pin2,...,pinn)`` - 参数 ========== ========== 参数 释义 ========== ========== pin1 第一个管脚 pin2(可选) 第二个管脚 pinn(可选) 第n个管脚 ========== ========== - 返回值 无 pio.pin.setlow() ~~~~~~~~~~~~~~~~ 设置管脚为低电平(0) - 语法 ``pio.pin.setlow(pin1,pin2,...,pinn)`` - 参数 ========== ========== 参数 释义 ========== ========== pin1 第一个管脚 pin2(可选) 第二个管脚 pinn(可选) 第n个管脚 ========== ========== - 返回值 无 pio.pin.setpull() ~~~~~~~~~~~~~~~~~ 配置IO口默认状态 - 语法 ``pio.pin.setpull(method,pin)`` - 参数 ====== ================================================================= 参数 释义 ====== ================================================================= method pio.PULLUP：上拉模式 。pio.PULLDOWN：下拉模式。pio.NOPULL：高阻态 pin 配置管脚 ====== ================================================================= - 返回值 无 - 例子 .. code:: c pio.pin.setpull(pio.PULLUP,pio.P0_5) --配置为上拉 --pio.pin.setpull(pio.PULLDOWN,pio.P0_5) --配置为下拉 --pio.pin.setpull(pio.NOPULL,pio.P0_5) --不配置上下拉 .. rubric:: pio.pin.setdebounce() :name: pio.pin.setdebounce 配置IO口消抖时间 - 语法 ``pio.pin.setdebounce(ms)`` - 参数 ==== =============================================== 参数 释义 ==== =============================================== ms 延时消抖时间，0为关闭消抖功能，开机后默认为20ms ==== =============================================== - 返回值 无 - 例子 :: pio.pin.setdebounce(20) --延时消抖设置为20ms pio.pin.setdebounce(5) --延时消抖设置为5ms pio.pin.setdebounce(0) --关闭延时消抖功能 相关资料以及购买链接 -------------------- 相关开发板购买链接 `Air720开发板 `__ `相关软件资料下载 `__ 常见问题
