What about 8x40 lcd's with PIC in the future?

Post by caesar »

Just played around with _X7JAY7X_'s PIC serial backpack.
I know that on LPT it isn't possible to wire more than 2xHD4470 BUT

It hit me the idea that it would be possible in the future version of Smartie to implement a custom MO extended set where there would be possible to wire 4 or more HD4470 to a microcontroller.
PIC 16F877 would be a good candidate... the 8 data wires will be the same for all HD's only 2 more pins will be sacrificed for enable lines. But this would be possible only if Smartie can support it...

What do you say?
This would be a tough job for our dear developers.

It would be very easy to do in the PIC. I actually plan on rewriting most of the routines for the 4x40 beta version once I get a few testers that report no problems. It would be a matter of defining a few routines for the extra enables.

I will ask the core developers if they can look into extending just the row and column command to allow multiple LCDs.
