ARM: Where can I find example projects in MDK?

Information in this knowledgebase article applies to:

MDK v4.x and v5.x

Question

I am starting a new project. Is there an Keil MDK example available?

Answer

There are several places you can look for examples. Here is a list of potential sources:

The Pack Installer contains many of the latest Keil MDK examples. This is the preferred method of delivery in Keil MDK v5, for examples, and several layers of software. Click the icon in Keil MDK, and select a device family from the Devices tab. Then the Examples tab will show you corresponding Keil MDK project(s).
```
Tip: In the Examples tab,
disable the Show examples from installed Packs only checkbox
to show examples from any published pack.
```
Click the Install button beside an example, and the Pack Installer will download the software pack containing the example. The use of software packs conserves memory on your development machine, and allows for built-in version control of external software layers.
The Pack Installer, in addition to device family packs, includes: â€“Middleware, such as the Keil File System, USB, and Network Components, and third party middleware vendors, like Clarinox Wireless, RealTimeLogic, Micrium, and Oryx Embedded. â€“RTOS tutorial examples, â€“ARM CMSIS updates, and â€“mbedTLS and mbedClient updates.
Keil MDK v4 legacy support includes examples for earlier boards and devices. These examples are all Keil MDK v4 style projects. If your 32-bit device is only found at the following URL:
```
www.keil.com/dd
```
and not at:
```
www.keil.com/dd2
```
Then you should install Legacy Support for these earlier devices. After downloading either Cortex-M or ARM7/9/Cortex-R4 legacy support, install the add-on into the same path as your Keil MDK installation.
```
Default installation path:
C:\Keil_v5
Examples are available in the following paths:
C:\Keil_v5\ARM\Boards\ 
C:\Keil_v5\ARM\Examples
```
To open the Keil MDK v4 project file, *.uvproj, launch the µVision IDE, and go to Project => Open Project...
Application notes and tutorials offer detailed labs and procedures, which often include examples.
- Keil MDK Application Notes
- Application notes developed by a silicon partner for Keil MDK
Examples written by a silicon partner for MDK, but distributed in a different way. Examples may be:
- Projects delivered in a pack, but that are not described by its pack description file (*.pdsc).
```
Note: The Pack Installer extracts files from packs into the path below:
C:\Keil_v5\ARM\PACK
[ --- assumes default installation path of "C:\Keil_v5\" --- ]
```
- Projects shipped inside a software development kit, the export feature of a project-building tool, a zip file, or other download source. This can include packs that are available online, but have not yet been published. Below is a list of possible sources:
  - Atmel: See Microchip.
  - Dialog Semiconductor:
    - Use Dialog's Software Development Kit(SDK) for DA1458x examples. (As of this writing, November 2017) a user account is required.
  - Microchip (Atmel):
    - Latest pack downloads may include new packs which have yet to be published through ARM's review process.
    - Export to µVision from Atmel Start
    - Zip file of SAM V71 / V70 / E70 / S70 "Software Package"
    - Zip file of AT91SAM software package
  - Nordic:
    - Keil MDK projects offered inside the nRF5 SDK. This kit includes a wide variety of examples for both the nRF51 and nRF52 device families, and is the preferred delivery method of Keil MDK examples developed by Nordic.
  - Nuvoton:
  - NXP:
    - MCUXpresso: NXP's SDK includes (formerly Freescale) Kinetis examples among many other device families. First, login to NXP's site. Keil MDK projects are offered inside MCUXpresso's SDK Builder.Follow the SDK Builder link, click the Select Development Board button to find your device. Double click on your device or board. Under Actions, select Build MCUXpresso SDK. Then select Keil MDK in the Toolchain/IDE dropdown list. Then click on Request build button. Then download the custom SDK.
    - Keil MDK projects for earlier LPC microcontrollers are available inside LPCOpen.
    - µVision: Adding support for QN9020
  - STMicroelectronics:
    - Export to µVision from STM32CubeMX. If you follow the link, scroll to the bottom of the webpage, to start the download.
    - Keil MDK projects offered inside STM32CubeMX Repository. After launching CubeMX, go to Help => Install New Libraries to download a repository for a device family.
```
Default path of repository:
C:\Users\___account_name____\STM32Cube\Repository
```
    - BlueNRG-1 DK (includes BlueNRG-2 Keil MDK examples)
  - Texas Instruments (TI):
    - TivaWare for TM4C devices
    - Unpublished pack (delivered as in a zip file) for CC13xx/CC26xx devices
```
Note: (As of this writing, November 2017) JLINK is the only supported debug unit
for the CC13xx/CC26xx devices in Keil MDK.
```
      The pack downloads are at the bottom of the above web page.
```
Tip: If you are exporting to an MDKv4 style project,
or using an old download from a silicon partner,
and still want to use a new feature in MDKv5, this may still be possible.
Download Legacy Support (see above) in order to use the example.

```
Google search query:

```
    KB articles may include code samples and procedures related to a particular goal, feature, or use case. Keil MDK users similarly will discuss a wide variety of topics, including code examples. You may similarly search through our user forum:
```
Google search query:
site:www.keil.com/forum  error: L6236E:
No section matches selector - no section to be FIRST/LAST
```

If you are aware of any other sources of Keil MDK examples from silicon partners, feel free to contact support, to update the list above. Be sure to reference this article.

If you still cannot find a specific example, either look at an existing example for a similar device, or contact a silicon partner to request the development of Keil MDK examples for a device family.
