I tried to connect a 0.96" 128x64 monochrome OLED display to my Arduino Nano.
http://www.electrodragon.com/product/0-96-12864-oled-display-iicspi/
They look like the ones on this page even though their backs are a little different.
I purchased each of both types. The I2C OLED worked as advertised but the I2C/SPI one has some issues.
The OLED shown on the webpage has 7 pins while mine has only 6 pins. Mine has all the pins except for CS (Chip Select).
My I2C/SPI module has soldering pads in its back that says "I2C" and "SPI" and the SPI pads are shortened by its manufacturer. Unless I desolder them, its I2C interface is disabled. It does not provide any clue regarding its I2C address. Either 0x78 or 0x7A, I guess. I'll probably never use its I2C mode.
My I2C module with an address of 0x78, has a 470k resistor soldered between the 0x78 bonding pads in is back side. This resistor can be detached and soldered on the 0x7A pads. It's painful to work on these itsy-bitsy SMT parts. But at least I can still manage to have two of them on the same I2C bus.
Does it mean my I2C/SPI OLED module will always have its SS (select) line set at low?
Does it mean I can never use two of these I2C/SPI modules on the same SPI bus? -- Toytoy ( talk) 03:13, 17 July 2016 (UTC)
Files that I have deleted and thrown in the Trash-can, only to empty the trash-can afterwards, is it possible to recover those files ? If so, how ? Tell me step by step if you're willing.

While doing binary calculation such as : 11001+110*101011 Can we use BODMAS rule here or not? — Preceding unsigned comment added by Sahil shrestha ( talk • contribs) 13:57, 17 July 2016 (UTC)
Does anyone know about InterNIC? Please go to the discussion at Talk:InterNIC#What happened to it after 1998? -- Quest for Truth ( talk) 17:48, 17 July 2016 (UTC)
Thanks all of you! Can I say that the organization ceased to exist in 1998? I'm adding the article to Category:Organizations disestablished in 1998.-- Quest for Truth ( talk) 16:19, 20 July 2016 (UTC)
