How to Install EmbeddedGNU 1. Install the GNU compiler. If you have not already installed the GNU gcc compiler for the 68hc11/68hc12 MPUs, then you must do this now. Get the main distribution file from this site: http://www.gnu-m68hc11.org After downloading the compiler, install the compiler on your computer. I normally install it into the default directory of C:\usr, but you can install it whereever you want. I like to use a short pathname for the install directory, so I don't like to install it under C:\Program Files, like most other windows software. 2. Install EmbeddedGNU on your computer. Make sure you extract the directory names when you perform the installation. Now start EmbeddedGNU. 3. Filename Association. When you first start EmbeddedGNU it will ask if you want to associate the filename extensions used by EmbeddedGNU with itself. This lets you double-click on a filename and the EmbeddedGNU will be launched to let you edit the file. The default option is to associate ".prj" with EmbeddedGNU. This is the main project filetype used by EmbeddedGNU. You can also choose to associate .c, .h, and .s files with EmbeddedGNU if you want to. WARNING: if you are on WinNT/Win2K/WinXp, then you must be logged in as an administrator to use this option. Press OK to continue. 4. COM Port Selection. Now it asks if you want to select your COM port. Say Yes. Pick your port in the dropdown box. It defaults to 9600 baud, which is normally correct. 5. Directories Before you press OK, switch to the Directories tab in this dialog. (If you pressed OK before coming here, then select "Options, Environment Options" to return here.) Specify the name of your GCC Bin directory, and the full pathname of your make program. Then press OK.
