Start a GMP project using TI Sysconfig

Preparation

For start a GMP project using TI Sysconfig for C28x devices, the following software should be installed first

  • Python3

Website: https://www.python.org/downloads/windows/

In order to run the GMP code generator scripts. In this document, we use Python 3.13 as example.

  • C2000Ware

Website:https://www.ti.com/tool/C2000WARE

In order to provide the library support for the devices. In this document, we use C2000ware 5.03 as example.

  • CCS

Website: https://www.ti.com/tool/CCSTUDIO

In order to create and build the TI C28x devices projects. In this document, we use CCS 12.8.1 as example.

  • Sysconfig

Website: https://www.ti.com/tool/SYSCONFIG

In order to generate TI initialize code. In this document, we use Sysconfig 1.21.2 as example.

User files

In GMP library, a general User file example is provided in <GMP>/core/usr. You may copy this folder to your workspace. Here is a brief introduction.

There are three files for controller implement.

xplt_ctl_interface.h provide the interface of the controller. User should implement the specific function to get input. If you disabled the Controller Nano, the following function would be called.

ctl_input_callback() this function will be called every MainISR, firstly.

ctl_output_callback() this function will be called after controller callback.

ctl_enable_output() this function should enable controller output.

ctl_disable_output() this function should disable controller output.

If you enabled the controller Nano, the following function would be called.

ctl_fmif_input_stage_routine() this function will be called every Main ISR, firstly.

ctl_fmif_output_stage_routine() this function will be called after controller callback.

ctl_fmif_request_stage_routine() this function will be called every Main ISR, after all the control law callback and output callback.

ctl_fmif_output_enable() this function will be called to enable output.

ctl_fmif_output_disable() this function will be called to disable output.

ctl_main.c will implement the initialization function.

ctl_main.h will implement the main control law function.

  • User main and peripheral manager

cplt.config.h project config headers.

user_main.c implement main init and loop function.

user_main.h header of user_main.c.

xplt.peripheral.c implement the peripheral init function.

xplt.peripheral.h define all peripheral declarations.

GMP Code generator tools preparation

In order to address GMP code, and add them to your workspace, we provide a easy tools for user.

You should copy the folder <GMP ROOTS>/tools/facilities_generator/gmp_file_generator to your own project workspace.

Config Compile environment

Add necessary header paths：

  • Necessary Library Path

  • User files path

  • GMP generated path

Add GMP related files to compiling list.

Add User files to compiling list.

Enjoy and Start your own controller
