Graphic Bar hold values

Hello everyone,

I just finished my code for a power meter and I am using an LCD 16x2 in which first line has the bar graph (using LcdBarGraph.h) and second line has PWR xxxxW SWR x.x

My problem is that the power I am mesuring is not constant at all, it is always changing so the bar graph is moving very fast and the PWR values.

Has anyone done some sort of hold for a few milliseconds the graphic bar. This is called the Peak measure and Average mesure. I want to display the Average mesure.

Any help would be appreciated.

Regards,
Filipe
