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 display. If you have a strain or a
|

correct display (can happen with chinese) you can copy those parameters and
