ssd1306

Hi all, I'm using the example
https://www.matrixtsl.com/wiki/index.ph ... Graphical)
The example works correctly but if I use a ssd1306 or ks108 display it doesn't work, and also if the height is set for example to 30 he draws a strange square but if I then put the height 30 he always keeps the first set.
same effect also loading on micro and also on arduino it has the same defect.
both in simulation and programming the microcontroller does not work correctly , or am I wrong?
Do you have any examples to send me? Thank you
