答案对人有帮助，有参考价值 0 ESP32-C3 支持使用 GPIO 唤醒，但在某些情况下，可能无法正常工作。以下是一些建议和解决方案： 1. 确保您使用的 GPIO 引脚支持唤醒功能。并非所有 GPIO 引脚都支持唤醒。请查阅 ESP32-C3 的技术手册以获取支持唤醒的 GPIO 引脚列表。 2. 在进入深度睡眠之前，使用 `esp_sleep_enable_ext0_wakeup()` 函数配置唤醒源。例如，如果您希望使用 GPIO 0 唤醒，可以这样设置： ```c esp_sleep_enable_ext0_wakeup(1ULL << 0, ESP_EXT0_WAKEUP_ANY_HIGH); ``` 这将配置 GPIO 0 为高电平唤醒。 3. 确保在进入深度睡眠之前，GPIO 引脚已正确配置。使用 `gpio_set_direction()` 函数设置 GPIO 引脚的方向，例如： ```c gpio_set_direction(GPIO_NUM_0, GPIO_MODE_INPUT); ``` 4. 检查您的硬件连接是否正确。确保 GPIO 引脚与外部设备正确连接，以触发唤醒信号。 5. 如果问题仍然存在，您可以尝试使用其他 GPIO 引脚作为唤醒源，以排除硬件问题。 6. 检查您的电源和时钟配置。深度睡眠模式下，某些电源和时钟配置可能影响 GPIO 唤醒功能。请查阅 ESP32-C3 的技术手册以获取更多信息。
