How many LCD diplays per core

[michiel]

Hey you all,

Can anyone tell me how many LCD displays one core can handle?

I'm thinking about making a controller with A graphic main display (blue)

and 4 encoders with 4 16x2 Blue displays next to them.

those displays show the parameter and value.

greetings michiel

Normally one core can handle only one display. But there are some exceptions:

-MBSEQ can handle 2 displays.

- 1 core can handle up to 8 I2C-Displays

Thnx raphael

So i'll be needing a LCD Displacy with I2C Bus connection or a I2C bus interface to

connect an normal HD44780 LCD Display??

This is the plan ;)

Does such a interface exist? I wonder...

Please read everything on the LCD page. For some displays you`ll need a special driver (you can integrate in MIOS). Look at the MIOS download page (http://www.ucapps.de/mios_download.html) what drivers are available. Or write your own driver ;)

This is the plan

Looks nice ;D

Yes i found an interface at www.channaa.com

There are also a few LCD displays with an I2C connection but i havent found a blue one jet.

I'm stil wondering if my plan is possible ?

one large main display an four 2 x 16 sub displays to show the parameter and it's value.

Do you have programming skills to implenent this into the application?

I mean: MIOS provides the basics to control multiple displays, but the application itself has to send some useful data to the additional displays... unfortunately, the MB64/MB64E is written in assembler, therefore it's not so easy to extend them if you never programmed PIC assembler before.

Alternatively you could implement something similar in C - this isn't so difficult, but examples are rare

The hole idea is to use the top encoder to flip thru the pages of an VSTi instrument or channel settings insert fx etc.

And use the four smaller displays to show the parameter and his value.

I wan't the value in the displa  in place of any ledrings around the encoders would this be possible with some or a lot programming?

With the C wrapper this shouldn't be that much effort... especially, since you only want to control a host application, where MIDI events could be statically defined (I guess that you don't want to change MIDI events directly on the LCD, when you are also able to edit them in your host sequencer?)

Best Regards, Thorsten.

Hello everybody,

As it looks hard to find 240x64 KS0108 controlled LCD, I wonder if it is possible to use two 128x64 instead. It seems possible to plug the two ones the same way exept for CS3 and CS4 for the 2nd LCD. Doas anybody try this ?

Thanks

Yes, it works with two 128x64 displays

Best Regards, Thorsten.

Thanks for quick answer
