SSD1315 oled display

Hello folks,

recently I bought a bunch of 128x64 and 128x32 I2c oled displays with SSD1306 driver, but after few try's I realized it came with different driver.
The actual driver is SSD1315. I try get it worked with Richard's includes but no success. The displays not get initialised. In available "datasheets" I can't see any major differences.
Then I tryed the displays with arduino and its includes (named as for SSD1306 and the displas works).
If anyone has any suggestion how to deal with this SSD1315 driver displays in PBP, it will be great.

Thanks,
Louis
