T1894_KEYPAD, COMPILATION ERROR. W11-64

T1894 vs T1709 (Version of Reference as full OK) :

Compiling this example (published as #22) with T1894 gives the error shown, with T1709 it compiles ok. I attach example and the used lib.

Tell me please...



Thakns for the new 1894, it has notable improvements and solutions.

Compiling this example (published as #22) with T1894 gives the error shown, with T1709 it compiles ok. I attach example and the used lib.

It works for me in R1894.
Where do you have Keypad library?
And which "Libraries Path" are you using in the compiler configuration?

The same configuration in both cases:



-----------------------------------------------------



This is the directory that by default Arduino 1819 assigns for the user libs at the Arduino installation.

I'll investigating for my side in order to have for data.

Other test:

It happens the same with all the programs that use libs.

The same configuration in both cases:

R1709 don't have "Libraries path", so it is not the same if you use it in R1894.

Seems that the Libraries path you are using is wrong.
If you are using the default libraries path, which seems the case, then leave it empty.
Or use some path where you have the libraries: C:\users\primy\Documents\Arduino\libraries

This is the directory that by default Arduino 1819 assigns automatically for the user libs at the Arduino installation. Where are all my libs...




---------------------------------------------------------------------------

Then if you are using the default library path, just leave "Libraries path" empty.

It make sense, let me try...

You are right, It works, thanks for your help.
