Step 23: Diagnostic Scan Screen
As soon as you connect the batteries, your Ognite should spring to life!
The first thing it will display is the Diagnostic Scan Sequence. It will individually turn on each LED starting in the lower left corner and working it's way left-to-right then bottom-to-top. Once all the LEDs are on, then it repeats the pattern turning them all off again.
This gives you a chance to make sure that all your LEDs are connected correctly.
If you see an LED that just won't light (as shown in the photo), then get out your soldering iron and fix the cold connection to that LED.
If a whole column or pair of rows doesn't light, then check the solder connection for that row/column to the chip leg.
If you see the LEDs come on in the wrong order, or skipping rows, then you probably made a mistake following the map. Don't say I didn't warn you.
If you don't see anything, check the batteries and their connections.
The pattern will run though once each time the Ognite powers up, so to see the pattern again just disconnect the batteries and reconnect them again.
Once the diagnostic scan finishes, the Ognite will automatically jump into flame display mode!
