Therefore, execute the following in the Pi Terminal: sudo apt-get install i2c-tools It appears, at least on my Raspberry Pi setup, I only need to install one package.

Secondly, we now install the dependencies required by the SMBus2 library.

Then on the next screen, choose I2C to enable the interface. The Raspberry Pi Configuration Tool will now open to allow you to select interface options. So, open a Terminal session on the Raspberry Pi to execute the following command: sudo raspi-config. Also, to support the SMBus2 Python library, we need to install some dependencies.įirstly, we configure the Rasberry Pi to enable the I2C interface. The Raspberry Pi is going to need some initial configuration to run the example code. Setup and I2C Test Code Arduino and Raspberry Pi Test Circuit You may need to perform retries until the serial interface returns to normal operation.

However, you can use exception handling in the code to prevent your program from crashing. So, the more read methods I perform per second the more I2C bus errors I get.Īlso, while mostly affecting the Pi zero, execution of another process can interrupt the I2C stream and cause increased errors. And this is measured by the number of failed read methods within the stream. On initial testing, the Raspberry Pi B3 outperforms the Pi Zero by more than a hundred times. However, the example code is still a work in progress, and some tuning is still necessary for the final I2C serial application. Using the included example code, I was able to test the performance of both the Raspberry Pi B3 and the Raspberry Pi Zero. Also, the Arduino microcontroller executes program functions in real-time as opposed to an operating system queueing tasks for execution. And this is due to the Arduino having onboard peripherals such as Timers, ADC and many more built-in modules.

I think it’s true that the Arduino boards are a much more reliable platform than the Raspberry Pi when comes to timing critical functions. I also include both Raspberry Pi and Arduino code to demonstrate the use of the serial interface. So, in this feature, I look at how to access an Arduino board from the Raspberry Pi using this serial bus. At some point, I’ll be looking to extend my Raspberry Pi robot, and one of the ways to do that is to use I2C (Inter-Integrated Circuit) serial devices.
