Supported values : ssd1306 (default), ssd1322, ssd1325, ssd1327, ssd1331, ssd1351, sh1106.

#### 2. Configure storage info
#### 2. Configure display info
For now **sys-oled** is a very crude python app that will require you to edit it directly in order to customize what you want to display.
Edit **sys-oled** script and look for the *status()* function.
By default **sys-oled** will display usage info of your micro SDcard which is most probably your Root File System. You can display storage usage info of one more storage device by editing */etc/sys-oled.conf*
```
sudo nano /usr/local/bin/sys-oled
sudo nano /etc/sys-oled.conf
```
You can edit the following lines to define for which storage devices you want to display info.
You can edit the following lines to define for which storage devices you want to display usage info.
```
d.text((0, 27), disk_usage('sd', '/'), font=font, fill="white")
d.text((0, 39), disk_usage('md0', '/mnt/md0'), font=font, fill="white")
# Storage Device 1
# Device name
storage1_name = sd
# Device mount path
storage1_path = /
# Storage Device 2
storage2_name= md0
storage2_path= /mnt/md0
```
In the above example, we are displaying **sd** (SDcard) usage which is the rootfs mounted on *'/'*. We are also displaying **md0** (RAID array) that is mounted on *'/mnt/mnd0'*.
The values *(0, 27)* and *(0, 39)* correspond to the X, Y positions of displayed texts.
