gpiod_set_value_cansleep(gc5025->reset_gpio, 1); 因为DTS 里面的 active 状态是 GPIO_ACTIVE_LOW,所以这个代码输出的是 低电平 gpiod_set_value_cansleep(gc5025->reset_gpio, 0); 输出的是高电平 这几个函数如下: int gpiod_get_raw_value(const struct gpio_desc *desc)void gpiod_set_raw_valu...
A4: 如果使用该GPIO时,不会动态的切换输入输出,建议在开始时就设置好GPIO 输出方向,后面拉高拉低时使用gpio_set_value()接口,而不建议使用gpio_direction_output(), 因为gpio_direction_output接口里面有mutex锁,对中断上下文调用会有错误异常,且相比 gpio_set_value,gpio_direction_output 所做事情更多,浪费。
