I get only the upper half of the string printed on the screen. Arduino Pro Mini with a 0.96" monochrome 128x64 screen and SSD1306 controller

Hi!
Thanks for the library!
This is the constructor I have been using:
U8G2_SSD1306_128X64_NONAME_1_HW_I2C u8g2(U8G2_R0, /* clock=/ SCL, / data=/ SDA, / reset=*/ U8X8_PIN_NONE);
I have tried 1_HW, 2_HW, 1_SW, and 2_SW. I get only half the line with all these.
If I try F_HW or F_SW the Arduino freezes when I instantiate u8g2.
Cheers
Eduardo Peloso.
