Two line LCD double height numbers, possible ???
I have Melanies excellent Olympic Timer from 2004 working as a seconds stopwatch, as I need seconds not minutes for Showjumping timing. i.e 128.34 secs (Thanks Melanie)
However I used a two line 40 character LCD and the numbers are very small.
I seem to recall in the past I saw a two line LCD showing numbers spread over two lines (two line high) using the custom character feature.
Anyone have any info on this ??

Hmm, a search came up with this on the Arduino forum.

Shows what can be done using just a few segments. I really need to study this one though to use the LCD.

Does the datasheet for your LCD mention custom characters?
As far as I remember, you need a graphic LCD to do that. A character LCD only prints characters, unless it has a custom character feature.

Most character LCD's allow up to 8 custom characters. I have a 2x8 display on my kids aquariums showing water temp and you have to be very close to read it, this would be a neat way to make the characters larger.

I thought about implementing this idea some time ago, but them I got discouraged when I read somewhere that these LCD displays only allow a few custom characters like spcw1234 mentioned above. However, looking at the arduino link above it looks like it can be done.

Darrel did it a long time back, I re posted his code here:http://www.picbasic.co.uk/forum/show...hlight=bignums
search for bignums to see other threads.
BTW Darrel gives credit to Scott Edwards . . .
