Dragon Board Help

[StudentMike]

Hello, I have recently recived my dragon board. And need some help in getting started, I am trying to do a simple excersice from a book which you press any key from the boards 4x4 key pad (0-9 and A-F) and that key is displayed on the seven segment. The book shows the solution in assembly language, but im workin with C language. Can anyone show me how you would do that kind of a problem in C language so I have some kind of an idea?

Thanks I see the keypad program, but it is attached to many other programs. I was looking for a concentrated program so i can visually see how to set up such program. Do you have a simplified example?

I try opening the Dragon12CWTest.mcp file and when it loads a message saying :

The following access path in target "RAM App using DBUG12" of project "Dragon12CWTest.mcp" cannot be found:
{Project}..\miniDragon12_CW_Test\sources

is this because i dont have coadewarrior installed on my labtop? I am using EmbeddedGNU software.

Oh, I see you are not using CodeWarrior (which is free BTW).


Then try this.

Forgot to mention the MCU i am using is the HCS12.

Take a look at this.
You may have to adjust the decoding table depending on which version of the board you have.
