A utility for writing text to an SSD1306 based OLED on the Raspberry Pi.
I use cheap OLEDs to display relevant information about what's running on my Pi. Currently the easiest route is to install the Python library and write a small program to display text to the Pi. In my case, I just want a small, dependency free executable which can write text out to the OLED.
With the 128x32 OLED:
echo -e "192.168.0.124\nSome status\nAnother Line\nGoodbye World" | delo
With the 128x64 OLED:
echo -e "192.168.0.124\nSome status\nAnother Line\nGoodbye World" | delo -height 64
One line install and Usage (requires i2c to be enabled)
curl https://github.com/mdp/delo/releases/download/v0.0.1/delo_Linux_arm.tar.gz | tar xvz && echo -e "Installed" | ./delo
modprobe i2c-dev
Inside of Docker
CMD modprobe i2c-dev && echo -e "Test output" | ./delo
- Run sudo raspi-config.
- Use the down arrow to select 9 Advanced Options
- Arrow down to A7 I2C.
- Select yes when it asks you to enable I2C
- Also select yes when it tasks about automatically loading the kernel module.
- Use the right arrow to select the 'Finish' button.
- Select yes when it asks to reboot.
