switches 0:5c4d7b2438d3 1 # About the exporters
switches 0:5c4d7b2438d3 2
switches 0:5c4d7b2438d3 3 The mbed exporters are used to export your code to various 3rd party tools and IDEs. Each exporter implements a `generate` function that produces an IDE specific project file. Exporters benefit from [mbed build tools](https://github.com/ARMmbed/mbed-os/blob/master/docs/BUILDING.md#build-mbed-sdk-library-from-sources). However, instead of using your source and [config data](https://github.com/ARMmbed/mbed-os/blob/master/docs/config_system.md) to create an executable, we use that information to populate an IDE project file that will be configured to build, flash, and debug your code. You can find exporter implementations [here](https://github.com/ARMmbed/mbed-os/tree/master/tools/export).

switches 0:5c4d7b2438d3 10
switches 0:5c4d7b2438d3 11 If you have added new target to the mbed SDK, exporting will allow users to transition from mbed source code to the offline development environment of their choice. This functionality activates the use of your device for larger number of users.

switches 0:5c4d7b2438d3 14
switches 0:5c4d7b2438d3 15 Eclipse project export utilizes a generated Makefile for building. Other than target configuration within the [config system](https://github.com/ARMmbed/mbed-os/blob/master/docs/mbed_targets.md) for mbed build system support, there is no additional work to provide Make export.

switches 0:5c4d7b2438d3 22
switches 0:5c4d7b2438d3 23 ### CMSIS Packs
switches 0:5c4d7b2438d3 24
switches 0:5c4d7b2438d3 25 UVision and IAR both utilize [CMSIS packs](http://www.keil.com/pack/doc/CMSIS/Pack/html/index.html) to find target information necessary to create a valid project file.
switches 0:5c4d7b2438d3 26
switches 0:5c4d7b2438d3 27 We utilize the tool [ArmPackManager](https://github.com/ARMmbed/mbed-os/tree/master/tools/arm_pack_manager) to scrape [MDK5 Software Packs](https://www.keil.com/dd2/Pack/) for target information. This is achieved by parsing [http://www.keil.com/pack/index.idx](http://sadevicepacksprod.blob.core.windows.net/idxfile/index.idx). The relevant information in the [PDSC (Pack Description)](http://www.keil.com/pack/doc/CMSIS/Pack/html/_pack_format.html) retrieved from each URL in the index is stored in [index.json](https://github.com/ARMmbed/mbed-os/blob/master/tools/arm_pack_manager/index.json). A `.pdsc` file typically describes a family of devices. Each device is uniquely identified by its [device name](https://github.com/ARMmbed/mbed-os/blob/master/docs/mbed_targets.md#device_name). Thus, this name makes a natural key to associate a device with its information in `index.json`.

switches 0:5c4d7b2438d3 29 #### What's in a device name?
switches 0:5c4d7b2438d3 30 There is no reliable way to map an mbed alias like [NUCLEO_F030R8](https://github.com/ARMmbed/mbed-os/blob/master/targets/targets.json#L603) to its unique identifier, [STM32F030R8](https://github.com/ARMmbed/mbed-os/blob/master/targets/targets.json#L615), as it is listed in a CMSIS pack (and subsequently `index.json`). So, we added a [device name](https://github.com/ARMmbed/mbed-os/blob/master/docs/mbed_targets.md#device_name) field in `targets.json`. **This field is required for IAR or UVision exporter support**.

switches 0:5c4d7b2438d3 33 http://www.keil.com/pack/Keil.Kinetis_K20_DFP.pdsc is the PDSC that contains TEENSY_31 device (MK20DX256xxx7). It has been parsed by ArmPackManager and stored in `index.json`. The device information begins on line 156:

switches 0:5c4d7b2438d3 51 The dname (device name) field on line 156 directly corresponds to that in the Uvision5 IDE target selection window. [`tools/export/uvision/uvision.tmpl`](https://github.com/ARMmbed/mbed-os/blob/master/tools/export/uvision/uvision.tmpl#L15), uses target information from these packs is used to generate valid Uvision5 projects. If the device name is not found, we use a generic ARM CPU target in Uvision5.

switches 0:5c4d7b2438d3 54 [`tools/export/iar/iar_definitions.json`](https://github.com/ARMmbed/mbed-os/blob/master/tools/export/iar/iar_definitions.json) utilizes this device name to store information necessary to set the target in an IAR project.
