ESP32-0.96寸OLED作为BLE Client与ESP32-BME280 BLE Server通信 总结 简介 两个ESP32开发板,一个ESP32挂载一个BME280传感器读取温湿度值并通过BLE低功耗蓝牙GATT协议发送数据,另一个ESP32通过BLE低功耗蓝牙与ESP32-BME280建立连接并在0.96寸OLED显示出BME280的温湿度值, ESP32-BME280作为BLE Server BME280传感器...
把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。由于...
(包括:ESP32- d0wd、ESP32- d0wdq6、ESP32- d2wd、ESP32- s0wd)集成了Wi-Fi和双模式蓝牙。根据型号差异,ESP32包含一个或两个低功耗Xtensa®32位LX6微处理器(s),最大时钟速度240 MHz(通常是160 MHz)和Xtensa RAM / ROM,本地内存和JTAG接口。 处理器: 主处理器: Tensilica Xtensa 32位LX6微处理...
摘要:本文对 ESP32 芯片 ADC 的 API 进行了详细说明,包括ADC单次模式和ADC连续模式下的所有函数,并通过实例程序演示应用功能(附源代码)。 ADC(analog to digital converter)模数转换器,是一种非常常见的外设,用于将电压等模拟信号转换为数字形式,以便微控制器可以读取和处理。 ADC 在控制和监测应用中非常有用,因...
The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE, debugging via native USB...
