Part A: Obtaining and Installing MDK and the Examples:
1) Keil Software Download and Installation: 1. Download MDK 5.11 or later from the Keil website. www.keil.com/mdk5/install
2. Install MDK into the default directory. You can install into any directory, but this lab uses the default C:\Keil_v5
3. We recommend you use the default examples directories for this tutorial. We will use C:\MDK\ for the examples.
4. If you install MDK into a different directory, you will have to adjust for the directory differences.
5. You need an external debug adapter such as the Keil ULINK2 or a ULINKpro. A Segger J-Link will also work.
MDK 5 vs MDK 4: MDK 5 does not include processor support files such as headers, peripheral, Flash programming and example files. These are downloaded and installed for each processor family using Software Packs. This provides many advantages.
If you need to run MDK 4 projects, download and install the Legacy Support: www2.keil.com/mdk5/legacy.
With Legacy Support installed, MDK 5 will run both MDK 4 and MDK 5 programs.
2) The ULINK2 Debug Adapter: The ULINK2 adapter is used exclusively in this lab. You must install the provided 10 pin Coresight cable in the ULINK as shown on the first page. You can use a ULINKpro. Page 5 contains a test for a debug adapter.
The Signum ADM-51 will not work with a Cortex-M processor, only with 8051 devices.
3) Example Programs: The example programs are provided in the MDK 5.11 Software Packs. The next page describes where to install these examples.
4) Getting Started MDK 5: Obtain this useful book here: www.keil.com/mdk5/.

5) µVision Software Packs Download and Install Process: The entire project and required files are contained in a Software Pack. A Pack is normally distributed on a website and accessed with the Pack Installer utility in µVision. A .pack file can also be imported manually into µVision.. A Pack is a zip file renamed with a .pack file extension. This enables µVision to recognize it. If you double-click on a pack file, µVision will install it. You can also select File/Import from the Pack Installer main menu.
1) Start µVision, open Pack Installer:
1. Install MDK 5.11 or later. www.keil.com/mdk You do not need a license for this tutorial.
2. For this tutorial, you need to be connected to the internet (it will display ONLINE in the bottom right corner in the Pack Installer utility in µVision. See the first screen below).
3. Start µVision by clicking on its desktop icon.
4. The Pack Installer window shown below will open: If not, open it with its icon:
5. If the Pack Installer Welcome window opens, please read it and close it.
2) Download the Maxim Zeus Software Pack: Note: you can also locally import a .pack file. Select File/Import.
1. In the Devices tab, select Maxim/Zeus or in the Boards tab select DB-MAX71637. This filters the Packs tab.
2. In the Packs tab, select Install for Keil::Zeus_DFP. This pack will be downloaded and installed from the web.
3. A successful install is indicated by the Up to date icon:
TIP: You can refresh the Packs
list from the web with or local files with File/Refresh.
3) Copy the Hello and CMSIS RTOS Examples:
1. Select the Examples tab. There are two examples provided in this Software Pack as shown here:
2. Select CMSIS-RTOS Copy as shown:
3. The Copy Example window opens up: Unselect Launch µVision. Select Use Pack Folder Structure as shown:
4. Type in C:\MDK for the Destination Folder.
5. Click OK to copy the RTX_Blinky project to C:\MDK\Boards\Maxim\DB-MAX71637.
6. Repeat for the Hello example.
TIP: The default directory for copied examples the first time you install MDK is C:\Users\<user>\Documents. For simplicity, we will use the default directory of C:\MDK\ in this tutorial. You can use any directory you prefer. Pack Installer creates the rest of the directory tree after C:\MDK\ in this case.
7. Close the Packs Installer. You can open it any time by clicking on its icon.
TIP: An Update icon means there is an updated Software Pack available for download.
TIP: If you look in the directory C:\Keil_v5\ARM\Pack\Keil\ZEUS_DFP\1.0.0\Boards\Maxim\DB-MAX71637, you will find the RTX_Blinky and Hello projects. This is the read-only version you downloaded used for backup purposes. Use only the projects you copied over from the Examples tab to the directory you chose: in this tutorial we have used C:\MDK.

16) Creating your own MDK 5 project from scratch: All examples provided by Keil are pre-configured. All you have to do is compile them. You can use them as a template for your own projects. However, we will start an example project from the beginning to illustrate how easy this process is. Once you have the new project configured; you can build, load and run a bare Blinky example. It will have an empty main() function so it does not do much. However, the processor startup sequences are present and you can easily add your own source code and/or files. You can use this process to create any new project, including one using an RTOS.
Install the Maxim Zeus Software Pack for your processor:
1. Start µVision and leave in Edit mode. Do not be in Debug mode.
2. Pack Installer: The Pack for the Zeus processor must be installed. This has already been done on page 4.
3. You do not need to copy any examples over.
Create a new Directory and a New Project:
1. Click on Project/New µVision Project…
2. In the window that opens, shown below, go to the folder C:\MDK\Boards\Maxim\DB-MAX71637\
3. Right click in this window and select New and create a new folder. I called it BlinkyNEW.
4. Double click on BlinkyNew to open it or highlight it and select Open.
5. In the File name: box, enter Blinky. Click on Save.
6. This creates the project Blinky.uvproj in C:\MDK\Boards\Maxim\DB-MAX71637\BlinkyNEW.
7. As soon as you click on Save, the next window opens:
Select the Device you are using:
1. Expand Maxim, then Zeus Series, and then select MAX71637 as shown:
2. Click OK and the Manage Run Time window shown below bottom right opens.
Select the CMSIS components you want:
1. Expand all the items and select CORE and Startup as shown below. They will be highlighted in Green indicating there are no other files needed. Click OK.
2. Click on File/Save All or select the Save All icon:
3. The project Blinky.uvproj will now be changed to Blinky.uvprojx.
4. You now have a new project list as shown on the bottom left below: The appropriate CMSIS files you selected have been automatically entered and configured.
5. Note the Target Selector says Target 1. Highlight Target 1 in the Project window.
6. Click once on it and change its name to Zeus Flash and press Enter. The Target selector name will also change.
What has happened to this point:
You have created a blank µVision project using MDK 5 Software Packs. All you need to do now is add your own source files.
