[WB] 40x2 Green-on-Black Optrex Display - or other colors

[ganchan]

I'm searching for a spare 40x2 Green-on-Black Optrex Display, mine got busted on the backlight and changing the smd leds it's quite impossible :)

Or two spare of another color same size.

Regards.

Would it be possible to use 4X 2x20 LCD display instead of 2X 2x40 on a MBSEQ V4? I have a small supply of really nice VFD's but they are 2X20 character HD44780 compatible.

 

Thanks!

 

... And it would be so really cool....

to have  something like a display like 2X8  or 3X8 for each encoder 

( 16 encoders with 16 display , 24 encoders with 24 display , etc...)

I don't remember now if here or elsewhere a controller project for synth edit-control 

with 16-24 oled displays , each for a single encoder..

(also in group of four as in the attached)

Could work, but you'd need a custom firmware and separate select lines for each LCD.

MIOS8: A special driver module is available which allows to connect up to 8 CLCDs to a single core (clcd_multi). Displays have to be selected with the USER_LCD_Select function by the application.
Connectivity: any free pin of the PIC can be used for the enable line. For instance, if your application doesn't use the analog pins at J5 of the core module, you are able to connect 8 additional LCDs. You could also program a multiplexer interface in order to address even more LCDs by routing the enable line to one PIC pin.
Wiring Diagram: mbhp_nxclcd_mios8.pdf
MIOS32: the standard CLCD driver is prepared for controlling up to 256 devices selected via MIOS32_LCD_DeviceSet(). Please understand this value as a theoretical possibility, physical parameters (like cable capacities) have to be considered as well. ;-) 
Connectivity: see this MIDIbox NG Manual Chapter.
