    Default Code for Driving 2,3 or 4 seven segment displays

    Hi all,
    I have recovered from the forum background a code to drive 4 seven segments displays, because there seems to be some interest in project of this type at this time.
    You can configure all possible versions: 2,3 or 4 displays, Common cathode, common anode and with or without
    transistors. Likewise you can configure the decimal point in the position you want.

    You can find the code here.

    Hi John,
    I have written this code quickly to help a PDS user. I have already found new tricks to increase the speed and efficiency of the program. I could write an article for the end of this week.

    Thank you Joseph, Teo & Charlie,
    Only I try to occupy my brain, if it can be useful for the PDS users.

    22/06/2018 Update code for driving 8 displays with one PORT only with the help of a simple and economical logic. (74HC5411 + 74HC238) Also I have updated the previous codes. All codes are built as 3 libraries.

    I'm thinking of another crazy thing, like sending to the displays some integer, signed variable or float numbers and floating DP with a single library. To be continue...

    Enjoy the code. See the article HERE.

    06/28/2018 update:
    I added a macro to input all variables for the library. It is more easy for the code user. (version 3.0)

    Very Soon: New library to print Integer, Signed and Float variables to the 7 segments display.

    New library for 3 to 8 seven segment displays
    (The definitive solution)

    Hi all,
    Thanks to the wonderful features of the PDS compiler, I was able to finish this project with a new library, allowing Integers, Signed, Float variables & Strings to be printed on the 8 digit displays.
    Please read the article in the WIKI.

    I have thought that adding 4 resistors I could insert a keyboard with 12 to 32 keys. This has not occurred to me before because it must be for my age now. Some ideas come too slowly.
    The software, more complicated, is a question of a brain storm of many hours.
    The project is finished in Proteus, it will be published soon.
