What is going on?
My i2c table is full of addresses but I don’t have any device connected.
Can anyone help me?
Raspberry pi 2 - Home Assistant.
I’m trying to use a BPM085 device.
pi@OM_Raspi ~ $ sudo i2cdetect -y 1

The SDA and SCL isn’t reverse and using a pullup resistor.
the 1-wire was on gpio 24 (pin 18) and I changed to gpio 26 (pin 17), using a pullup resistor too.
I run some test:
- I disconnect all devices and the i2c table runs ok, complete empty. I connect the BPM085 and the table show up just with te address 77 (0x77 = BPM085) . Fine.
- I connect the DHT22 on gpio 22 (pin 15), reboot the Rpi and the DHT22 looks like fine. But the Table of i2cdetect show up full again.
- I disconnect the DHT, reboot, then the table show up fine, just with address 77 (0x77 = BMP085) again.
- I connect the 3 BS18B20 (1-wire) gpio 24 (pin 18) , reboot, and the table i2c is full again.
- I disconnect the 3 BS18B20 and conect a single led on gpio 5 (pin 29) restart the Pi and the table show up full again, and again and again and again.
Conclusion for me:
This device runs just lonely. They don’t like companion. I guess…It’s so sad…
Another one advice, please???
