Raspberry Pi I2c Read/Write Error

Like many people, I've had a Pi for a while but never really done anything with it. I've finally got round to hooking up an MPU6050 IMU to play around with. It uses i2c for communi

Solution 1:

In normal cases you don't really need to change the /lib/udev/rules.d/60-i2c-tools.rules file, so I would recommend resinstalling raspbian.

Connect the MPU6050 to the correct pins:

Then download an official Adafruit library:

• C++
• Python

Check if the Raspberry Pi's I2C is enabled with $ sudo raspi-config and make sure the I2C address is correct, besides checking it with $ i2cdetect -y 1, like this:

try:
  bus = Adafruit_I2C(address=0)
  print("Default I2C bus is accessible")
except:
  print("Error accessing default I2C bus")

mcp = None

for i in range(0x00, 0x28):
    try:
        mcp = Adafruit_MCP230XX(address=i, num_gpios=16)
        break
    except:
        pass
