Multi Function Shield errors

I am revisiting a Multi Function Shield. When previously used the #include was MultiFuncShield.h, however this seems to have been replaced with MultiFunctionShield.h. Now when I compile I get error messages such as
MFS not declared in this scope Any advice?

Start by posting a sketch that causes the error and the the full error copied from the IDE using the "Copy error message" button

Put the sketch and error message in code tags when you post them

Also, please post a link to the shield (and if not available through library manager, the libraries).

Please edit your post, select all code and click the </> button to apply code tags and next save your post. It makes it easier to read, easier to copy and prevents the forum software from incorrect interpretation of the code.

I doubt it is a replacement; just somebody else writing a similar library.

MultiFuncShield.h can still be found at Arduino Multi-function Shield Projects - Hackatronics after a bit of googling. I installed version 1.3, took the Arduino 24 Hour Alarm Clock from
Learning to code with the Arduino Part 3 and it compiles; you might need an older version if your original code relies on the TimeOne library.

Instructions for installing v1.3

  1. Download https://files.cohesivecomputing.co.uk/MultiFuncShield-Library-1_3.zip
  2. Extract
  3. Navigate to the directory where_it_was_extracted\MultiFuncShield-Library-1_3\MultiFuncShield-Library-1_3; it contains the directory MultiFuncShield-Library.
  4. Copy the directory MultiFuncShield-Library and paste it in the Arduino Libraries directory (on my system, C:\Users\sterretje\Documents\Arduino\libraries)

Hi,
If the newer library you are having problems with has examples, it is work worth loading them and checking the variable/functions they use.

Tom... :smiley: :+1: :coffee: :australia:

Also use the "code" tags to show error or serial monitor output.

I tried pressing the <> key with the code highlighted and it was replaced by <. What am I doing wrong?

It's a button, not a key
