Remember Processor Expert? Just to refresh your mind, is a development system to create, configure, optimize, migrate, and deliver software components that generate source code for Freescale silicon, supporting S08/RS08, S12(X), Coldfire, Coldfire+, Kinetis, DSC 56800/E, QorIQ and some other Power Architecture processors. And well, what's the such new great thing in it? Take a look: Microcontroller Driver Suite v10.0 is a software management system to perform Processor Expert's tasks and provide a low-cost, efficient solution for your designs. Just recently a great update has been made into it: the driver suite is delivered and installed as a comprehensive product with the Eclipse 3.7 (Indigo) IDE. It is also available as an Eclipse 3.7 plug-in. This extends Processor Expert software functionality to non-CodeWarrior IDE users for the supported platforms. The cool, useful part of all this is that Processor Expert technology packaged in the driver suite makes it much easier to optimize the low-level intricacies of a hardware platform. It also eliminates the necessity for one-size-fits-all drivers, therefore the driver suite allows you to design custom peripheral drivers ideally suited to your needs, without the need for extensive hardware knowledge! And just as aesy as that, you get a whole new set of possibilities to empower your design! You can try the software by just clicking here Microcontrollers Driver Suite v10.0 And you can also get the Driver Suite for Eclipse by clicking on here Microcontroller Driver Suite v10.0, for Eclipse 3.7 (Indigo)

The processor (CPU) component is automatically inserted to Processor Expert project at the time of its creation. It generates a code needed for very basic operation of the CPU and also a common initialization code for resources shared among the peripherals (like interrupt vectors table, clock control etc.). Clock settings The processor component is initially set to use no external clock sources (for example, crystal) and only one clock configuration is created. To adjust clock settings, use Component Inspector view to modify the properties in Clock settings and Clock configurations groups. Processor Expert instantly checks the timing of the whole project so the errors are reported if the timing settings are in conflict or cannot be reached. External bus and memory The processor component is initially set to use no external bus and only internal memory. To enable and configure external bus, use the Component Inspector view to modify the properties within the group External bus. The placement of individual data or code sections within the address space can be configured on the Build options tab of the Component Inspector. Importing Board Configuration The settings for the CPU can be imported from the file. If you are using standard Freescale board configurations, select the command File > Import… Then select Processor Expert / Apply Board Configuration. In the dialog that appears click Browse… button and look for a file with extension .peb at <CWInstallDir>\MCU\Processor_Expert\BoardConfigurations\<processor family>\<board name>\<module>. If your board is not available within the CodeWarrior installation, you can import the settings from other already configured project. In such case use the command File > Import… and then select Processor Expert / Component Settings to Project.

The C project that doesn't use Processor Expert can be converted to Processor Expert. This is useful when the user finds out that he/she would like to use additional features of Processor Expert. WARNING! Note that in most cases this conversion involves necessary manual changes in the application code, because for example the register interrupt vectors table definitions created by the user often conflicts with Processor Expert definitions. Don't forget to backup the whole project before the conversion. Some files will have to be removed from the project. The conversion to Processor Expert is recommended to experienced users only. Steps: Select the command in the main menu File > New > Other and in the New Project Wizard select Processor Expert / Enable Processor Expert for Existing C Project Select the project you want to update. Select the derivative that will be included in PEx project (you should use the same derivative with the _4SDK suffix that has been selected when the project was created without PEx). Select the target compiler (select the GNU C Compiler by default but if you have not installed any other compiler in the Kinetis Design Studio) Confirm changes (renaming of main.c module and any other changes you want to apply) and click on the Finish button. The project with PEx is created but there need to be done following changes: Go to project Properties to the Procesor Expert > Kinetis SDK Specific and fill the SDK path. Use browse button and select a path to the Kinetis SDK folder or fill the ${KSDK_PATH} which is default system variable. This variable points to the default Kinetis SDK folder. After this project still shows some errors. Remove the PinSettings component from project and add new PinSettings component from Components Library. This process adds missing fsl_clock_manager component to the project too. Press the button Generate Processor Expert Code and project should be generated without errors. Remove the duplicate main.c module – the main_backup.c file (copy content of the old main.c module into the new one created by PEx) and delete the old version of the file (main_backup.c) Remove all IO maps files from the original project. The KDS bareboard project have all these files included in the Includes folder by default (core_......h files and IO map files). Remove all startup files from the original project. The KDS bareboard project have all these files (startup_xxxxxx.S and system_xxxxxx.c files) included in the Project_Settings/Startup_Code  folder. Remove linker file xxxxxxxxxxxx_flash.ld from the original project. Use the Processor Expert.ld linker file that is generated by Processor Expert. In the context menu of the project select Properties and in the Properties window go the C/C++ Build > Settings > Tool Settings, select the Cross ARM C++ Linker / General and select the ProcessorExpert.ld file instead of MK......_flash.ld (see the following screenshot).

Therefore all IO maps and startup files from the original C project must be removed (e.g. content of the Static_Code folder). Processor Expert generate linker file ProcessorExpert.xxx (e.g. file ProcessorExpert.icf for IAR ARM C Compiler). Therefore all linker command files from the original C project must be removed.

This tutorial shows a basic steps to create a CodeWarrior project with Processor Expert configured for the FRDM-KL25 board. The steps apply to CodeWarrior version 10.3 or newer. 1. In the CodeWarrior , go for [File | New | Bareboard Project]. 2. Type a project name such as e.g. KL25Z-PE” then click [Next] 3. In Devices page, please go to the line [Device or board to be used], type in part of the name our target device:  "kl25z" and select the final target device MKL25Z128 from the filtered list. Then click [Next]. 4. In the Connections window select only the [OpenSource SDA] connection type and click [Next]. Note: This is the on-board USB debug connection on FRDM-KL25. 5. In the Rapid Application Development select [Processor Expert] and click [Finish]. 6. The CodeWarrior Projects view contains a newly created project. Double-click the Processor Expert.pe file to ensure to see  the Processor Expert components from the project in the Component view. 7. In the Component view open the view menu (small down-heading arrow) and select Apply Board Configuration command 8. Click Browse… button and select FREEDOM-KL25Z / cpu / CPU_default.peb 9. Click Finish to confirm replacement of the default CPU component by the pre-configured one for the FRDM-KL25 board. Now the project is configured to run from on-board crystal at 48MHz. You can continue with adding components from the Components library view and configuring them in the Inspector or for example try the follow tutorial Toggling Pin on Kinetis Using a Timer Output .

The Processor Expert Driver Suite 10.4 Update 2 is available on the Freescale web and as Eclipse update. This update applies to the Driver Suite 10.4, or 3rd party IDE's with Processor Expert as Atollic TrueSTUDIO or Emprog Thunderbench. It is NOT applicable to CodeWarrior or Kinetis Design Studio: the upcoming KDS V2.0.0 release will include that update. This update features an improved new project wizard with device filtering support, alignment with the Kinetis SDK v1.0.0 and the upcoming SDK v1.1, and includes bug fixes (see release notes for details). The update is cummulative, so you can apply it to Driver Suite 10.4 with or without the Update 10.4.1.
