Parent page: TaskingPinMapper Commands

The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to access the TASKING Pin Mapper wizard. The wizard enables you to synchronize pin mapping data from your microprocessor design - designed using your TASKING toolset - to your PCB design project in Altium Designer, without the need for transferring such data by hand, and therefore removing the need for exporting and importing files manually. The wizard facilitates data synchronization from the TASKING toolset’s own Pin Mapper to an Altium Designer schematic document. The resulting schematic document will reflect the device pin configurations that have been assigned and saved in a nominated Pin Configuration file (*.pincfg).


This command is accessed from the Schematic Editor by choosing the Tools » Tasking Pin Mapper command from the main menus.

The command will only be available provided the TASKING Pin Mapper Provider software extension has been installed as part of your Altium Designer installation. This extension can be found on the Purchased page of the Extensions & Updates view.


After launching the command, the TASKING Pin Mapper Wizard will open. The following pages of the wizard lead you through the process of creating a schematic from a specified TASKING Pin Mapper file.

Select the TASKING Pin Mapper File

Use this page of the wizard to specify the source pin configuration file (*.pincfg) to be used - this is the file generated from the TASKING toolset’s Pin Mapper.

Select Component

This page of the wizard will, if possible, populate with available options for the processor device.

If the Tasking pin mapper file has specified an explicit processor type, the system will attempt to locate it in the available Altium Designer libraries. Alternatively, if the pin file defines a processor family (say, the ST Microelectronics STM32_T2 family of ARM Cortex processors) the list will contain all compatible types from the Altium Designer library - select the desired processor variant from the list.

The processor list will be blank if a compatible processor library is not loaded or available in Altium Designer. Use the Install library button to locate and install a suitable Integrated library.

To select a different processor from that offered by the list, use the Other component button to open the Browse Libraries dialog. Select the desired library from the Libraries drop down menu and choose a suitable processor component from the list.

In the case where an explicit processor has been defined in the pin mapper file, or has been selected from a library using the Other component function, the list will show a single entry for the processor component.

Configure the Sheet

This page of the wizard defines the properties and behavior of the generated processor schematic.

Since the source pin mapper file defines both the pin functionality and external connections, its representative schematic needs to be configured to present that information in a way that is compatible with the target PCB design project. As such, this means basic name settings through to how pins, ports and compiler directives are handled.

The processor functionaly block can be created on a new schematic document, or an existing one.


This, the final page of the wizard, provides a summary of the selected settings. After clicking the Finish button, the new processor schematic document is added to the current project and opened in Altium Designer's schematic editor. The schematic will contain your microprocessor, with all of your original pin signal names and configurations.

The schematic uses Harnesses where applicable to provide a convenient and simplified connection process for the associated schematics in the PCB design project.


  1. The TASKING Pin Mapper wizard can also be launched automatically from within your TASKING toolset's Pin Mapper tool, with the required pin configuration file (*.pincfg) pre-loaded ready. If Altium Designer is not currently running, it will be started.
  2. The TASKING Pin Mapper provider extension provides bi-directional communication between Altium Designer's PCB Editor and your TASKING toolset's Pin Mapper tool. This allows you to interactively perform pin-swapping within the Altium Designer PCB design workspace, and dynamically synchronize changes with your TASKING Pin Mapper tool. This ensures that your TASKING embedded source code is kept in-sync, without the need to export and import change files.
