Once we have the Kernel driver up and running the tool will start to display UU instead, this is an indication that it is working as intended. This id is the address of the DS1307, DS3231 and the PCF85231 RTC Chips. If you have successfully wired up your RTC circuit, you should see the ID #68 appear. With those tools now installed run the following command on your Raspberry Pi to detect that you have correctly wired up your RTC device.

Run the following command on your Raspberry Pi to install python-smbus and i2c-tools: sudo apt install python-smbus i2c-toolsĨ. Once the Raspberry Pi has finished restarting we need to install an additional two packages, these packages will help us tell whether we have set up I2C successfully and that it is working as intended. Type the following command into the terminal on your Raspberry Pi to restart it. To do this first get back to the terminal by pressing Enter and then ESC. However, before I2C is genuinely enabled, we must first restart the Raspberry Pi. Once the raspi-config tool makes the needed changes, the following text should appear on the screen: “ The ARM I2C interface is enabled“. You will now be asked if you want to enable the “ ARM I2C Interface“, select Yes with your arrow keys and press Enter to proceed.Ħ. On the next screen, you will want to use the arrow keys to select “ P5 I2C“, press Enter once highlighted to choose this option.ĥ. Once this option has been selected, you can press Enter.Ĥ.
Use the arrow keys to go down and select “ 5 Interfacing Options“.

Today, however, we will only by exploring how to enable the I2C interface. This command will bring up the configuration tool this tool is an easy way to make a variety of changes to your Raspberry Pi’s configuration. Run the following command to launch the configuration tool. With the Raspberry Pi now entirely up to date we can now run its configuration tool to begin the process of switching on I2C.

Let’s begin this tutorial by ensuring our Raspberry Pi is entirely up to date this ensures that we will be utilizing all the latest software available. DS3231 & PCF8523īefore we begin setting up and utilizing our RTC on the Raspberry Pi, we first have to make use of the raspi-config tool to configure our Raspberry Pi for use with I2C.ġ. However, wiring up a normal PCF8523, DSL1307 and a DS3231 isn’t a complicated process, following our guide below you should have everything connected to in no time. For this tutorial, we utilized the Pi RTC PCF8523 from Adafruit which plugs in directly over the first six pins which significantly simplifies the process of setting up an RTC ( Real Time Clock) module.
You can either connect these lines directly to your Raspberry Pi or connect it to a breadboard and then to the Raspberry Pi. Some RTC circuits may come with more, but we only need the following four for it to work with the Raspberry Pi: VCC/ 5V/ Vin (IC Power-supply pin), SDA (Serial Data Line), SCL (Serial Clock Line) and GND (Ground power-supply pin) On your RTC Module, you should find at least four connections. Wiring your RTC module to the Raspberry Pi Equipment Listīelow are all the bits and pieces that I used for this Raspberry Pi RTC tutorial. We will also be showing you how you set the time on your real-time clock module when required to do so.
You will also be learning in this tutorial the changes you need to make to the Raspberry Pi’s configuration as well as modify packages on Raspbian, so it will read the time from your real-time clock module and not utilize the fake time it relies on by default. We will be showing you how each of the individual real-time clock chips needs to be wired up to the Raspberry Pi to function correctly by providing the pin numbers and a helpful GPIO guide.
