Dear All,
I am using KINETIS K64 MCU & PCF8553 LCD Driver.
Need SOURCE CODE for the same.
As of now I am able to glow segments individually & all segments are driven perfectly, meanwhile request NXP or other to share SOURCE CODE ( .c & .h files) for PCF8553 to do development quickly and correctly.
also there is a CLK Pin in this PCF8553 which can be used for Display backlight control, like reducing brightness to 50% after some delay & eventually 10% brightness
But, I am not able to configure the CLK for backlight control feature, kindly share SOURCE CODE for the same too.
Thanks in advance.

Dear Fang Li,
Thanks for reply,
We have gone through datasheet & AN11566 based on that we tried working on CLK to control backlight, it did not work. suppose we get to know the control register to be utilized or source code *.c & *.h generic code, so that we can customize ourselves.
Kindly guide.
Hi,
Sorry we do not provide the LCD driver by source code but only GUI. As for the CLK for backlight control feature, you may make reference below documents:
