软件
GPIO API API名称 说明 hi_u32 hi_gpio_deinit(hi_void); GPIO模块初始化 hi_u32 hi_io_set_pull(hi_io_name id, hi_io_pull val); 设置某个IO上下拉功能。 hi_u32 hi_gpio_set_dir(hi_gpio_idx id, hi_gpio_dir dir); 设置GPIO引脚方向id参数用于指定引脚dir参数用于指定输入或输出 hi_u32 hi_gpio_set_ouput_val(hi_gpio_idx id, hi_gpio_value val); 设置GPIO引脚的输出状态id参数用于指定引脚val参数用于指定高电平或低电平 hi_u32 hi_io_set_func(hi_io_name id, hi_u8 val); 设置引脚功能id参数用于指定引脚val用于指定引脚功能 hi_u32 hi_gpio_deinit(hi_void); 解除GPIO模块初始化
