Knowledge on Contrast Modification
There are differences in contrast between each LCD, so if your found content displayed is too dark or too light, you'll need to modify contrast variables of source code pcd8544_rpi.c, then recompile the source code and check the final result as well as corresponding changes!
May be need modify to fit your screen! normal: 30- 90 ,default is:45 !!!maybe modify this value! int contrast = 45;
Change this part. The default setting is 45. If it's too dark, decrease a little bit, If it's too light, increase a little bit. We recommend you decrease/increase by 5 points at a time.
After modification, source code should be recompiled before running
