LCDOUT with custom PINS

You could build your own serial back-pack.

Thanks but again a serial LCD is not the answer, it is more expensive, much more, it can cost up to 5 dollars each of the modules mentioned in your post. In this case i DO have the pinout needed to control my classic LCD.

HUH, the post I linked to is a discussion for building, not buying. Maybe it would cost $5 to build one though, depends on what you have laying around.

My misunderstanding, thought the problem was you do not have the pins needed?
Oh well, good luck.

Hi, i didnt reply because i was expecting the PCB, it was late so i got to work just today.

Darrel Thanks for your reply, i have been trying to figure your suggestion, i get the virtual port, but in the link

http://www.picbasic.co.uk/forum/showthread.php?p=22065

the example to use it to this specific case uses a HighJack.bas include that isnt posted anywhere.

Now if i get it well The HighJack.bas file must be used to replace a subroutine for a self made one, wich DO is on the post.

Now summary: The HighJack will replace LCDOUT for a selfmade, this LCD self made uses virtual PORT to write to the device.... If i am wrong please correct me.

Finally i will need HighJack.bas

On the other hand, is it really this hard to work with LCD`s isn´t there a simple routine that i can change just to make LCDOUT? which are the LCD commands?, i have never seen them.

Thanks

Hi Josuetas,

It really depends on what you need to do with the LCD.

If you just want to send individual characters to the LCD, you can use the program shown in the other thread, and by removing the HighJack reference and changing 1 other line, it will do exactly that. Which means the answer to the question is ... No it's not difficult to work with LCD's.

But that means you can't use PBP's LCDOUT statement. No DEC, HEX, STR, or anything else that goes with LCDOUT.

The hard part, is making a "custom LCD Driver" tie into PBP's LCDOUT statement so that it's completely transparent to the user. You would just use LCDOUT like you normally would.

Like I mentioned earlier, I have it working here. But I still haven't got it to where I can release it as "Working in all situations".

I'm sure I can get it working for you, but I want to do some testing here first. So I need to know EXACTLY what your setup is.

Originally you said 16F628.
Is that the standard or "A" version?

Are these correct?

Hopefully
PortA.6->D7
PortA.7->D6
PortA.0->D5
PortA.1->D4

And what about RS and E ?

OK, too slow.

You're probably in another timezone sleeping away..

Got it figured out.
