What's the trick with installing the trimpots in the SmashTV CORE?

Parts Questions

Hi. I am about to put everything into my CORE module and I was just wondering - with the trimpots that are supposed to adjust the LCD contrast and brightness, do I just turn the phillips screw all the way clockwise before installing and then reduce later? Will I have to open up the whole box every time I want to change these parameters?

Shouldn’t there be a way to adjust brightness/contrast from the console or somewhere on the outside without having to crack it open every time? I was just wondering - I’m not picky about the display values at all, I mainly just want to have the resistance value at the right place before putting them in. I don’t want to do anything wrong.

Thanks!

Don’t worry too much, just solder them in..

You might set them once (How bright do you want the screen etc) and thats it.. You won’t want to reach for these trimmers every time you use your midibox.

Set them in the centre for now.. you will see when you power up the core + LCD if you want it brighter / contrast etc.

(No harm can come to your midibox with those trimmers)

sorry just a bit in a hurry, hope that helps

You could actually dim the brightness and therefore select contrast rate using a pwm on some free pic s pins but that has never been done before as far as i can remember.http://en.wikipedia.org/wiki/Control_panel_(engineering
