Serial LCD Backlight Problems

ghost13

Hi,

I have the Prallax 2x16 Serial Backlit LCD. I programmed it as instructed, but the backlight doesn't turn on until after the first cycle. And after the 1st cycle, it doesn't stay on... it flashes rapidly and no text is displayed. My code is attached.

Any help is appreciated.

THANKS!!!

And calling [noparse][[/noparse]cpde]SEROUT 0, T2400, (17)[noparse][[/noparse]/code] also seems to move the cursor over to the middle of the screen.

Is this my fault?

I think that this is the problem you put

SEROUT 0, T2400, (17,12)

I think that it should be,

SEROUT 0, T2400, ($17,$12)

You needed to put the dollar sines in front of the numbers so that is shows that they are HEX numbers

That would make sense

Hmm...

I tried that, and no luck. Here's my example code:

SEROUT 3, T2400, ($22, $12, $17)
  SEROUT 3, T2400, ($17)
  PAUSE 5
  SEROUT 3, T2400, ("Insert into the", $13, "test chamber.")

It also displays the quote mark in ""Insert into the"" and ""test cahmber""

Also, how do I print a variable's value?
It was declared like this:

SYMBOL  apogee  = W4         ' base reading everything is based off of

Any help would be awesome!!!

Thanks

Thanks!
