16 segment code

[MAKInnovation]

I want to drive 16 segment for complete ABC display.
How could i easily do it with PIC16F877A.
Need your helping code for an ease.

You really need to supply us with more information ! What type of display( mfr/make/infosheet).

The simplest '16 segment display' that I've done was an LED version(hmm..might have been 14, no matter)...and used Ports B and D to control the anodes of the LEDs through 499r resistors.Once the translation table of 'character' to port/bits was created the rest of the code took maybe an hour or so.


There's also LCD displays....they take more time, so that's why you have to give us more info !

Also number of digits and maybe reason for choice of display.

Is it a cost sensitive application?

Or do you simply happen to have a display that you want to use for a project and don't want to throw away?

I am thinking to display my alphabatic DATA on 16 segment rather then on alphanumeric LCD 16X2 or 20X2 etc.

This is only because of the visibility of DATA from distance.

Or I need your suggestion to choice any other type of display for this purpose.

Depends on viewing distance. I've used strings of white 'rope' lights for large 7 segment displays as well as 2' and 4' long flourescent tubes as 'segments'of a BIG clock.

Start out small with a test using LEDs.
Once the code is cut for the 'local' LED it was simple to add the power driver circuitry to lightup the big display units.
