打开您的Arduino IDE，然后导航到File > Examples > ESP32 > Deep Sleep，然后打开TimerWakeup草图。
调用esp_deep_sleep_enable_ext0_wakeup(MY_RTC_WAKEUP_IO, WAKEUP_IO_LEVEL) 函数或 esp_deep_sleep_enable_ext1_wakeup(WAKEUP_PIN_MASK, WAKEUP_TYPE) 函数,设置从 Deep-sleep 模式下唤醒的 RTC GPIO 电压条件 调用esp_deep_sleep_start() 函数进入 Deep-sleep 模式 /* Deep Sleep with External Wake ...
参考:Arduino-ESP32 2.0.6 documentation 基本和【Arduino快速上手esp8266方案开发】类似,在ArduinoIDE的“首选项”对话框中找到“其他开发板管理地址” 并添加如下地址 稳定版发布链接: https://espressif.github.io/arduino-esp32/package_esp32_index.json 开发发布链接: https://espressif.github.io/arduino-esp3...
void esp_deep_sleep_start() 启动DeepSleep; void esp_deep_sleep(uint64_t time_in_us) 相当于直接设置定时器唤醒并启动DeepSleep; esp_sleep_wakeup_cause_t esp_sleep_get_wakeup_cause() 返回DeepSleep唤醒源,具体如下: ESP_SLEEP_WAKEUP_UNDEFINED reset was not caused by exit from deep sleep ...
二、软件实现(Arduino IDE) 安装依赖库: #include <Wire.h> #include <RDA5807.h> RDA5807 radio; void setup() { Serial.begin(115200); radio.init(); radio.setFrequency(103.9); // 设置初始频率 radio.setVolume(4); // 音量级别0-15
ESP32 是一款功能强大的低成本 Wi-Fi 和蓝牙双模芯片,在 Arduino 开发环境中使用时,可以快速实现物联网(IoT)项目。以下是简明指南: 1. 环境搭建 安装Arduino IDE:从官网下载最新版(需1.8.19以上版本) 添加ESP32 支持: 打开Arduino IDE → 首选项 → 附加开发板管理器网址输入: ...
V4.0，它包含一个USB转UART桥接器以及其他ESP32引出线以便于连接。编程使用Arduino IDE 完成。
In your Arduino IDE, open up the serial monitor and you will see the messages showing the boot count and the board going to deep sleep and waking up after every 5 seconds. Serial Monitor Pressing the ENABLE button on the ESP32 board will erase the RTC fast memory and the boot count wil...
The recommended programming tool for the XIAO ESP32S3 is the Arduino IDE, so as part of the software preparation, you will need to complete the Arduino installation. tip If this is your first time using Arduino, we highly recommend you to refer to Getting Started with Arduino. ...
