#概要

vistaでstm32duinoやってみた。
i2c scanner、やってみた。

#写真

#サンプルコード

#include <Wire.h>

void setup() {
	Serial.begin(9600);
	Wire.begin();
	Serial.println("\nI2C Scanner");
}

void loop() {
	byte error, 
		address;
	int nDevices;
	Serial.println("Scanning...");
	nDevices = 0;
	for (address = 1; address < 127; address++) 
	{
		Wire.beginTransmission(address);
		error = Wire.endTransmission();
		if (error == 0) 
		{
			Serial.print("I2C device found at address 0x");
			if (address < 16) 
				Serial.print("0");
			Serial.println(address, HEX);
			nDevices++;
		}
		else if (error == 4) 
		{
			Serial.print("Unknown error at address 0x");
			if (address < 16) 
				Serial.print("0");
			Serial.println(address, HEX);
		}
	}
	if (nDevices == 0)
		Serial.println("No I2C devices found");
	else
		Serial.println("done");
	delay(5000);
}

#結果

Scanning...
I2C device found at address 0x27
done
Scanning...
I2C device found at address 0x27
done
Scanning...
I2C device found at address 0x27
done

以上。
