# Display

|
Cleanflight supports displays to provide information to you about your aircraft and cleanflight state.
|
|
|
|
When the aircraft is armed the display does not update so flight is not affected. When disarmed the display cycles between various pages.
|
|
|
|
There is currently no way to change the information on the pages, the list of pages or the time between pages - Code submissions via pull-requests are welcomed!
|
|
|
|
## Supported Hardware
|
|
|
|
At this time no other displays are supported other than the SSD1306 / UG-2864HSWEG01.

### SSD1306 OLED displays
|
|
|
|
The SSD1306 display is a 128x64 OLED display that is visible in full sunlight, small and consumes very little current.
|
|
This makes it ideal for aircraft use.
|
|
|
|
There are various models of SSD1306 boards out there, they are not all equal and some require addtional modifications
|
|
before they work. Choose wisely!

The banggood.com display is the cheapest at the time fo writing and will correctly send I2C ACK signals.
|
|
|
|
#### Crius CO-16
|
|
|
|
This display is best avoided but will work if you modify it.
|
|
|
|
Step 1
|
|
|
|
As supplied the I2C ack signal is not sent because the manufacturer did not bridge D1 and D2 together. To fix this solder
|
|
the two pins together as they enter the screen. Failure to do this will result is a screen that doesn't display anything.
|
|
|
|
Step 2
|
|
|
|
Pin 14 must be disconnected from the main board using a scalpel. Then connect a 10nF or 100nF capacitor between pins 30 and the
|
|
lifted pin 14.
|
|
|
|
Step 3
|
|
|
|
Connect a 100K resistor between Pin 9 and the lifted Pin 14.
|
|
|
|
Failure to perform steps 2 and 3 will result in a display that only works on power up some of the time any may display random dots
|
|
or other display corruption.

## Connections
|
|
|
|
Connect +5v, Ground, I2C SDA and I2C SCL from the flight controller to the display.
|
|
|
|
On Naze32 rev 5 boards the SDA and SCL pads are underneath the board.
