Surplus LCD panals

[donhamilton]

hello All,

I have built an LCD controller pcb for use with surplus LCD panals.



I am new to LCDSmartie, but as you can see not AVR programming.

What would like to know the most direct path to get my board working with LCDSmartie.

If I created an AVR program that used the command sets of either Matrix Orbital (MO) Serial or Crystalfontz (CF) serial, would that be polite to MO or CF
.
Would they come after me ??

If I created my own command set, would I need to create a new DLL for LCDSmartie ??

Thanks

Nice LCD! Would you get 8 lines of 40 characters on that, using the standard 5x7 (or 5x8) characters?

The Matrix Orbital protocol is simple and widely supported, so I'd try that. I have no experience with CrystalFontz displays.

I doubt that anyone (Matrix Orbital etc) would be upset if you are just developing this for yourself. If you want to start selling kits, then you'd have to work out some sort of licensing agreement with whoever developed the protocol.

I and several others have developed PIC and AVR based emulations of the Matrix Orbital controllers for our own use or as an open hobby project with no issues.

Thank you for that information.

The Epson controller can natively support 80 chars X 25 lines, but the chars are small.
I wanted to make the display look like a 4x20 with huge chars, but when I found LCDSmartie I had all kinds of new ideas.

I have downloaded the manual for GLK240128, seems like a good place to start.

I have a few of these displays and controllers from another project, seemed like a waste to just trash them.

If you have any code you would be willing to share, I would be grateful.

I made a driver for an alphanumeric 8x24 display that I've released source code for - has some ideas on how to convert Smartie's 4x40 max screen size to 8x20 chars http://forums.lcdsmartie.org/viewtopic.php?f=8&t=1472

rfryar has developed a Smartie driver for a graphical LCD that allows you to display normal text data from Smartie http://forums.lcdsmartie.org/viewtopic.php?f=8&t=1464

Have a browse of the Plugins forum section (includes display drivers) for some more ideas/sources http://forums.lcdsmartie.org/viewforum.php?f=8
