00016 This particular display has a design error! The controller has 3 pins to configure to constrain
00017 the memory and resolution to a fixed dimension (in that case 128x128) but they leaved those pins
00018 configured for 128x160 so there was several pixel memory addressing problems.
00019 I solved by setup several parameters that dinamically fix the resolution as needit so below
00020 the parameters for this diplay. If you have a strain or a correct display (can happen with chinese)
00021 you can copy those parameters and create setup for different displays.
