SSD1306 OLED Screen turns off or goes to sleep?

[voodoochemist]

Hi,
I'm using an SSD1306 OLED 128x32 SPI. http://www.adafruit.com/products/661

I can't figure out why it keeps shutting off after about 2-10 minutes. I don't think the shutoff time is exactly consistent, but it's generally off after 3 minutes. Is there a sleep function that I can turn off?

I have tried to isolate if there is a conflict with something in my code, such as another device library, but I have my sketch really simple at this point: it's just the OLED and an UNO, and the OLED still goes off.

Help!

What turns it back on? Resetting the Uno?

Correct, pressing reset turns the screen back on.

I divided up my code into functions and now the screen is staying on. I must have had some overlapping code that was causing the screen to shut off. Thanks. Rule of thumb: when you're sketch gets complex (about 10 different routines going on) it's a good idea to divide up the code into functions.
