MSP430FR4131: LCD Fade out and segment problem.

Part Number: MSP430FR4131

Hi everyone,

I have connected an LCD to MSP430 microcontroller. I am using LCD_E controller and external charge pump capacitors (0.1 uF). I have configured everything correctly.

I have 4 COM pins, when I turn off a segment, all others 3 segments that are directly connected to same COM pins turn off. Plus, it seems brighter than on segments. So, there is a contrast problem too.

I tried all frequencies, voltage sources, clock sources and charge pump capacitor as 1 uF, but no luck :(

Thanks for your answers.
