PCA85133 Blink

Hi,

We are using PCA85133 with LCD and want to implement pattern blinking.

Could this LCD driver could achieved blinking specific pattern in display RAM and others could still display without blink?

First, set blinking mode with normal blinking and blink frequency selection is 3 then send display RAM through load-data-pointer. The patterns will blink as I expected, but if other display RAM was enabled, the whole pattern will blinking as well.

 

Thanks.

Hello Curly,

I hope all is great with you.

PCA85133 supports two kinds of blinking methods which are whole display blinking and an arbitrary selection of LCD segments to blink, please see below section 7.11 Blinking in the datasheet for the detail explanations for blinking methods.

I hope this information helps.

Regards,

David
