You can show the following information in a simple (and cheap) I2C 0,96inch OLED screen:
- CPU Temperature (Celsius)
- Free RAM Memory (Percentage)
- Used HDD (Percentage)
- Clock (HH:MM)
After the installation process, you need to meet a series of hardware and software requirements:
- Raspberry PI: Any model. Although this project has been tested on Raspberry PI Zero 2 W, Raspberry PI 3 and Raspberry PI 4.
- SSD1306: I2C (4 pin) 0,96inch 128x64 px OLED Display: You can buy it on Aliexpress, Amazon or Adafruit.
- MicroSD with sufficient space to alocate this project (3Mb).
- 4 cables to wire the screen to the GPIOs in the Raspberry PI.
- You need (obviously) the operative system installed. RaspiOS, Raspbian... the one you like the most, based on Raspbian.
- Need to be connected to the internet. The installer will install all the dependencies and will need an internet connection
- The user "pi" configured
- The user "root" available to run the installer (only works with root user)
You can follow the image below.
| SSD1306 | Raspberry PI |
|---|---|
| VCC | 5V (can be on 3v3) |
| GND | GND |
| SCK | SCK (GPIO3) |
| SDA | SDA (GPIO2) |
The installation is so easy:
- clone this repository in /tmp of your Raspberry Pi
# git clone https://github.com/weto91/OledInfo-Raspberry /tmp - Change permissions of the installer.sh file as root (700)
# chmod 700 /tmp/OledInfo-Raspberry/installer.sh - Run the installer
# ./tmp/OledInfo-Raspberry/installer.sh - Wait until the installation process finish and enjoy!
