I want to make a running text that we can type character directly using AT8951 microcontroller. But I don't know how to get data from PS-2 Keyboard. I have no idea how to use the 'Make Code' and 'Break Code' from keyboard.
I need help..
 

Hi,

usually you have to use unique flags for each key.

The "Make code" says that the keay is pressed. And the "Break code" says that the key is released.
So the flags should contain the actual key state.

The communication protocol you will find in internet.
