Hi

I am trying to interface OLED SSD1306 with CC2640 Launchpad. I am trying to use I2C driver using I2C example. However, I am not able to interface OLED.

Also, I wanted to know which libraries are to be used for CC2640.

I even tried referring to this Chinese blog for the same: https://blog.csdn.net/feilusia/article/details/52686966

They have interfaced OLED with cc2640 but when I tried the same way as mentioned by them, no positive result.

I suggest you using I2C protocol analyzer to check if your I2C signal is correct first.

I am afraid that I do not have I2C Protocol Analyzer.

Also, which library should I use for OLED, SSD1306?

and also commands to be sent over I2C for initialisation.

There is no dedicated I2C lib for SSD1306. I suppose you have to revise CC2640R2F I2C driver and change I2C command register according to SSD1306 data sheet to make it work.

You have to write a driver that uses this display yourself based on the display driver and the libraries that exist for this display for other MCUs, see github.com/.../Adafruit_SSD1306
