Please Help (Complete noob) cannot get the Adafruit SPI OLED to work with UNO

Other Hardware Displays

HI

I recently purchased a 1.27" adafruit SPI OLED breakout board from Adafruit OLED Breakout Board - 16-bit Color 1.27" w/microSD holder

It arrived today and i have been trying to get it to work with the tutorial they gave Wiring and Graphics Test | Adafruit 1.27" and 1.5" Color OLED Breakout Board | Adafruit Learning System

But so far i havent even been able to power up the screen. It did light up VERY briefly when i was moving the board around but this never happened again. I have done exactly as the tutorial said.

What i want to know is whether there is any settings that i need to activate to use the SPI bus?

P:S I have installed all the libraries and GFX that are given in the tutorial link and can see them under Files -> examples -> Adafruit-> Test

Please help

Adafruit libraries and tutorials are pretty well written

If you have a problem, you need to describe each step carefully. Say which step goes wrong. i.e. what you expect and what you get.

Well I expected the OLED to light up but even that hasnt happened even though i connected the ground and the %V wires correctly and followed the all steps exactly as shown in tutorial.

The only thing that i may have done differently is that i havent soldered the pins and the OLED together but i have made sure that the pins are in contact with the sides of the holes of the OLED.

Does that help?

any reply will help

Invest in a soldering iron. Or ask a friend to solder it for you.

So are you saying the reason the display isnt working might be because the pins are not soldered? Even though i made sure that they are all touching the sides of the pin holes?

I do have a soldering iron but am really not good with it and last time i ended up heating away the gold edges of the holes.

If i connect the 5V and Ground wires correctly with UNO and the display then atleast the OLED should start lighting up right?

There is a difference between me making sure that they are all touching the sides of the pin holes and you doing the same. :grinning:

Get some junked equipment to practice your soldering on.

Not necessarily (most likely nothing will light up). And that is great about OLEDs, they do not have a backlight like TFTs (and even if you had a TFT and backlight would work, it does not mean that your connections are ok anyway). Pixels light up individually on OLEDs so you won't know if it works or not until you actually draw something onto the screen.
