I am using the K30 to drive my LCD. My LCD operate at 5V with 8x24 LCD 1/3 bias.
I am able to run my LCD correctly after for few minutes. The problem comes after that. Some of the segment
that is should be off is turn on. I realize that the segment affected is only those at the BP5-BP8.
Fyi, I am using charge pump to drive my LCD.
Is there any register that I need to define beside LCD_GCR[DUTY] to make my LCD run properly.
