Have some problems with the operation of my keyboard along with the K3NG keyer.

As I understand, something has to be changed or supplemented in the library
to make my keyboard compatible with the K3NG keyer.
In the K3NG_keyer sketch, I read the following text:

To use FEATURE_PS2_KEYBOARD PS2you need the K3NG_PS2Keyboard.h and K3NG_PS2Keyboard.cpp library files from https://github.com/k3ng/k3ng_cw_keyer/t ... / libraries

If I go to the above site, I'll find the K3NG_PS2Keyboard folder.
I click on it, I find 3 files:

K3NG_PS2Keyboard.ccp
K3NG_PS2Keyboard.h
Library_properties.

  • I have no idea what to do with it, I can not download them.

  • And if it is possible in another way, where do I have to put it?

Can someone explain to me how to get my typeboard so that I
text can be found on my keyboard of the keyer.

Can someone help me to make the typed text readable on my dispay window of de K3NG Keyer.
