首先打开Arduino IDE,输入下面sketch扫描i2c地址 #include void setup(){ Wire.begin(); Serial.begin(115200); Serial.println(" I2C Scanner");}void loop(){ byte error, address; int nDevices; Serial.println("Scanning..."); nDevices = 0; for(address = 1; address < 127; address++ ) { Wir...
Upload the below sketch and open the Serial Monitor to view results: #include <Wire.h>void setup(){ Wire.begin(); Serial.begin(9600); while (!Serial); // Wait for serial monitor Serial.println("---I2C Scanner---");}void loop(){ byte error, address; int nDevices; Serial.println(...

If that describes you, then try running the following sketch. It will scan I2C possible addresses and report the address of the device that responds. address of the device that responds. I2C Scanner By Nick Gammon Copy, Paste, Upload and Run!
A user can convert any flowchart program into an Arduino or Raspberry Pi sketch and then type some additional code in either C++ for Arduino or Python for Raspberry Pi. For advanced users theProteus VSMproduct range is the natural progression. Working inside the same familiar software environment...

Here is a I2C scanner that works on ESP32's The Debug output shows my problem. The first section of output is what happens when the SDA line is held low by the ESP32. I touched EN(reset) on my WeMos bluetooth&battery. The reset cleared the SDA line and the scan successfully worked...
