# Delo
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.
#### Currently tested with
- [52pi 128x32 OLED](https://www.modmypi.com/raspberry-pi/breakout-boards/52pi/52pi-0.91-128x32-oled-screen-for-raspberry-pi)
## Example
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`
## Installation
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`
### Resin.io i2c setup
`modprobe i2c-dev`
**Inside of Docker**
`CMD modprobe i2c-dev && echo -e "Test output" | ./delo`
### i2c on Raspbian Jessie
1. Run sudo raspi-config.
1. Use the down arrow to select 9 Advanced Options
1. Arrow down to A7 I2C.
1. Select yes when it asks you to enable I2C
