Hey all, I want to explore the sleep modes on ESP32 using Arduino IDE. By referring the ESP8266 guide, I am able to put the ESP32 in deepSleep mode. I want to use my ESP32 in either lightSleep or modemSleep, both of which are not defined...
esp_err_t esp_sleep_enable_ext0_wakeup(gpio_num_t gpio_num, int level) 设置通过外部唤醒,输入参数为gpio口(如GPIO_NUM_35),电平(0=low 1=high); 可以使用的IO口为0,2,4,12-15,25-27,32-39; void esp_deep_sleep_start() 启动DeepSleep; ...
ESP32 支持 Deep-sleep 低功耗模式,通过配置 RTC 外设和 ULP 协处理器的工作模式,可以满足多种应用场景下的低功耗需求。 在Deep-sleep 模式时,所有由 APB_CLK 驱动的外设、CPU 和 RAM 将掉电,RTC_CLK 继续工作; RTC 控制器、RTC 外设、ULP 协处理器、RTC 快速内存和 RTC 慢速内存可以不掉电,具体取决于应...
It comes with a standard interface, making it compatible with a variety of Arduino boards and ESP32 modules. The module's low power consumption, reaching as low as 6mA in deep sleep mode, ensures that your projects remain energy-efficient. The module's lightweight design and compact size ...
DMA 缓冲区需使用__attribute__((aligned(4)))或malloc_caps分配内部 RAM(如MALLOC_CAP_DMA)。 资源限制 ESP32 的 DMA 通道有限,避免同时使用多个外设。 中断冲突 某些库(如 WiFi)可能禁用中断,影响 DMA 传输。 电源管理 低功耗模式(如 Light-sleep)可能关闭 DMA 时钟。 Arduinocore forESP32ESPESP...
