I looked closer at box the display came and it said it is for SPI mode. I tried i2C and didn't light up. Then, tried SPI and still no success. Doesn't seem to be a RST pin. I see no pictures of the same pin arrangement on the Net. Looks to be a special display no one knows about. Guess I'll return it and hopefully the SSH1306 will be available soon, Sorry to take up so much room here is this comments section. Moderator, you can delete all I said on first post. donde

Screen Never Lights
New to OLED. Waiting for SSH1306 1.3" display like on Adafruit website. Sent for SH1106 display instead. Pinouts are left to right: VDD VSS SCK SDA D/C CS1 FS0 CS2
Using Pi Zero. Went through tutorial OK I think. 2 problems:

root@raspberrypi:~# ls /dev/i2c*
/dev/i2c-0
root@raspberrypi:~# ls /dev/spi*
/dev/spidev0.0 /dev/spidev0.1

The first check returned /dev/i2c-1 instead of /dev/i2c-0
The second response was OK.
Now I wasn't at root when I did commands, but at user.
Other problem I had to supply sudo for
./oled_demo --verbose --oled 6
I received this:

pi@raspberrypi:~/ArduiPi_OLED/examples $ ./oled_demo --verbose --oled 6

Nothing on screen!
I wired it this way from Pi Zero
Pi 5 volts to Vdd
Pi GND to Display VSS
Pi SCL to Display SCK
Pi SDA to Display SDA
IO25 to Display FSO

No ID on Display, just this description:

Not sure what try next. What turns on screen to see at least something?
Thanks ... donde
