设备故障:I2C 设备本身可能存在故障,导致无法正常通信。 3. 解决方法和步骤 检查硬件连接 确认SDA 和 SCL 的正确连接:确保数据线(SDA)和时钟线(SCL)正确连接到相应的引脚上,并且连接牢固。 检查引脚分配:确认代码中使用的引脚与硬件连接一致。例如,在 Arduino 中,你可能需要使用 Wire.begin(SDA, SCL) 来指定 SD...
Polling an I2C sensor (Sensirion SDP810-125) at 1000 Hz works with arduino-esp32 v2.0.3 but doesn't work with v2.0.4 and so on (same story with the latest v2.0.7) Could be related to #7209 --> It's not a library- or sensor-specific issue. I mean, it's the Wire issue -...

(source: https://www.arduino.cc/en/Reference/Wire) Pro tip For devices that don't use de-facto standard register scheme you can use the low-level methods directly I2c._start(); I2c._sendAddress(slave_addr); I2c._sendByte(my_byte); I2c._stop(); For more details see the ...
This BMP280 sensor library uses I2C communication with Arduino/ESP8266 and read the Temperature( degC) , Pressure (mBar) and Altitude (m). - mahfuz195/BMP280-arduino-library
