Which LCD does Graphics+text

Kosti

New member
Hello,
I'm not sure if you have answered this in your Forum elsewhere, as I'm interested and new to this LCD display stuff. :D

My first issue is I'm after a display that will do both graphics and text and to be HD44780 compatiable ?

Does a 16x2 do graphics and text or just the 20X4 and above.

Do I have an option for serial/parallel at these dimensions, doesn't this matter? Which is better ?Why?

What are the available colors that this type of 20x4 would come in.

Main issue, can I get it sent downunder (AUSTRALIA) or do you have a dealer here in Australia, Sydney, Melbourne etc :eek:

I saw your blue 16X2 CFAH1602B-TMC-JP can the character display color be changed from white to black ? :confused: Do you have a 20X4 with the same colour scheme ?

P.S. Sorry for asking so many questionsm hope you can point me in the write direction

Regards
Kosti :)

HD44780 controllers cannot do graphics. They're alphanumeric-only. The only custom graphics possible are the eight 5x7 custom characters you can upload.

Regarding S vs P, parallel displays are considerably cheaper, but it's not ready-to-run out of the box. To attach them to a PC, parallel displays need either a "backpack" converter board (four companies make them that I know of for serial, and there's a USB one in development by Skylab PC) or to be wired directly to a DB-25 hood and plugged into the parallel port. And in the case of the parallel port, you won't be able to use the software out there for it if you're running a NT kernel system (NT4, Win2K, WinXP) unless it's been explicitly written for it.

Serial, on the other hand, is just a matter of plugging in a two-headed serial cable and setting a baud rate.

CrystalFontz' serial 20x4s AFAIK are only in standard black-on-green transflective positive. There's no way to change the character color in a display of that type, unfortunately - that's a transflective negative display, and what you're actually seeing is a pure white backlight shining through blue LCD liquid. Blue is hard to get right in transflective positive, unfortunately :(

Brent will have to handle whether or not there's an Australian or NZ distributor.

Hey Uller,

Thanks for taking the time to point out a few things regarding the S vs P and some limitations of the HD44780.

I guess I'll have to check which LCD is suited for what I want to do, which is basically motherboard monitoring of heat, etc, seeing music artists would be a bonus.

Can you tell me, as I have seen some displays do EQ / Bar graph type displays when using under winamp, I think it was O/Cmod.com, can't remember, so is this just using a block to show music levels ?

If that's the case then I wouldn't require the graphic type.
Cool
Thanks again.
PEACE

If you mean these:





Then yes, a CrystalFontz unit will do fine. Those shots were actually taken with a 634 (serial 20x4).

Thanks guys for the replys, You will be sure to hear from us soon.

A friend is trying to gather the numbers to place an order as we don't want to be hit by import tax :). His name is PapaSmurf and has posted here, questioning about frieght and costs etc. I have sent this thread to him via mail, so hopefully your will be sending stuff downunder.

Cheers

PS. I went to our local radio shack store here in Sydney and bought a cheap LCD to give it a whirl and see if I can get it to work. It's a standard 16x2 Dot Matrix LCD module with a built in LSI controller, KS0066, now I hope this is HD44780 compatiable :(, I guess I'll have to try and see. I asked the guy at the store and he could even tell me if it was a S or P type or if it was compatiable..

Anyway, thanks again and you'll be hearing of more for here in Oz.

I hope it's compatible with 44780, since it's the chip on the CFAH parallel units ;) ( It don't explicitly say so in the datasheet anymore, but it used to, and the initialization flowcharts are nearly identical to the samsung documentation ;) )

About the only difference is that it runs at 300kHz instead of 250kHz, so it's got a slightly wider margin for timing.

It really works

YEP, Finally finished wiring up the 16x2 LCD LSI controller KS0066.

**** this thing really works. I wired the LCD as per a diagram that I saw on this forum, I grounded the contrast (VO) and grounded the Read/Write Select (R/W) as I will only be writing. I also grounded pins 18-25 parallel, although I guess I could leave these unconnected.

15, 16 has been left unconnected as it doesn't have a backlit option on this LCD.

WOW, this is running something, now to figure out what to display as there are so many options.

PS> crystalfontz, I believe we have placed an order with you guys, hopefully they arrive with no hassles, can't wait for the 634 type LCD, oh yeah and the blue one. :D :D

Thanks again
Will keep intouch
Kosti
