This particular display has a design error! The controller has 3 pins to configure to constrain
|

the memory and resolution to a fixed dimension (in that case 128x128) but they leaved those pins
|
||||
configured for 128x160 so there was several pixel memory addressing problems.
|
||||
I solved by setup several parameters that dinamically fix the resolution as needit so below
|
||||
the parameters for this diplay. If you have a strain or a correct display (can happen with chinese)
|
||||
you can copy those parameters and create setup for different displays.
