Text output to graphic LCD

[F1CHF]

Thanks for coming back
I didn't see that this thread was so old !
It is the first time for me with GLCD display
I have uploaded the PDF, is it suffisant to find which kind of controller it uses ?
I hope so ..
Tell me if I am right ...
I have a process that fill a variable "toto" with a value (let say H for HELLO as a numeric value, because in PBP we can't handle alphanumeric)
Through a Lookup table (as described in this thread) I will be able so feed a table
with ROW1 to ROW7 ...(for example)
I just need to send thoses rows to get the character displayed ?
That would be nice, is to get a Sub routine (like LCDOUT) and just jump to it with
the character fill in "toto" .. I am right or outside my shoes ?
thanks in advance

Hi, François

On my side ... I've got a turnaround ...

using a dedicated PIC just to care of big GLCDs ( 128*64 or over ). as it needs some ( LOL ) memory and time to write the whole screen ...

The project was published in EP issue 279 ..., allows a 9600 Baud serial transmission from the PC or a Pic and the use of simple commands for classical shapes ( point, circle, box ...).

If you want, I'll post you a copy of the full project ( no more downloadable from the EP site ) ... and "THE" SlotH ( Petter) listing.

If that page doesn't give you enough to understand those filters ...

There's no more to do for you than sell hotdogs, bretzels or pizzas ( even donuts ) in the street ...

I also remember having seen some of these filters used in UAV's ...

So, I suspect more a SEARCHing problem than an Understanding problem ...

But it's me ...

Hi Alain,
I looked at the whitepaper on that website . . . is that really math or pop art?
You wanna buy a hot dog?

Hi, Joe

Was somewhat like that when I first discovered Fuzzy Logic ...

You know what ???

I DO HATE Maths ... But will surely enjoy a good Hotdog !!! _ Making Hoddogs is a full job. Programming Pic too.

LOL !!!

Alain

Gotta use that search engine

You are fairly close in your thinking...
I don't remember the thread, but there is one floating around here that deals with that 122x32 LCD that I whipped up some PBP code for, including a fairly robust font table.
Looking at the attached datasheet, with a few changes, it should be easily adaptable to the 128x64 LCD you are talking about (change the maximum's to 128x64 instead of 122x32, change the maximum X,Y for characters from 20x4 to 21x8, all characters are 5x7(6x8 with seperator), and some other minor timing changes.

Here it is...

My god ....not a piece of cake !
Mister PBP, please create a GLCDOUT command ! hi ...
thanks or your help
I must work on now ....

True, it's not a piece of cake....
In the end, my code going out to the 122x32 LCD looks like this:
@ printstr 2 , 1 , "This is a string"

Prints "This is a string" starting at X position 2 on the 2nd line down from the top.
You can't get a whole lot easier than that!....well, once the code is in place anyways.

At any rate, I'll look thru that datasheet a bit harder later on. Like I said, I understand my code (nobody else likes the way I write, but that's ok). If it really is that easy to convert over to the KS type controller, I'll have a go at it sometime this weekend and let you know when I get something done up. - DONE

See the thread referenced in Post #29 for some code for the 128 x 64 graphic LCDs...and pay heed to the notes contained. I'll start a different thread once that code is tested and verified working.

Are these things hard to drive?
Can I write, in PBP, simple programs to display text easily, or is it tres dificile?

None de ceux que I know ne sont as this compliqué

Basically, once you got a working example for a X controller, you just need to adapt it to another... looks easy huh?

How to have success.. Buy both GLCD type, download and print both datasheet, buy a crate of beer, sit back and relax a little bit while comparing both datasheet.

Then you try few things... and that's where the fun begin A swear jar is recommended
