The C2000 Microcontroller (MCU) Workshops have been developed to help engineers gain a full understanding and complete working knowledge of the C2000 MCU family. Learning is accomplished through a detailed workshop manual and by performing the hands-on lab exercises. Each workshop starts with the basic concepts and progresses to more advanced topics in a logical flow. The topics and lab exercises build on the previous one completed, running a common theme throughout the workshop.
Does your industrial control system include customized logic? Do you have an FPGA, CPLD, or external logic components supplementing your embedded controller and wonder “why can’t this all be done in one device?” Are you using this additional logic because your MCU peripherals don’t give you all the capability you need? With the Configurable Logic Block (CLB) peripheral you are able to implement custom logic and even augment existing C2000 peripherals like the PWMs, captures, quadrature encoder, and GPIOs. This can enable you to integrate critical functions into a sing
This module covers the architecture of the CLA, the resources at its disposal and the division of code into task blocks that are triggered by peripherals or through software. Each of these task blocks are atomic, in the sense that no other task may interrupt a running task. This makes operation of the CLA unconventional in comparison with standard CPUs.
The CLA is supported by a subset of the ANSI ‘C’ Compiler. You will learn the features, and more importantly, the limitations, of this compiler in this video. The video also covers the changes in the linker command file needed to support operations on the CLA
In this video we get into the actual workshop. I will take an existing project for the C28x, a simple example that samples an EPWM, runs it through a low pass filter, and then an FFT to get the frequency spectrum, and migrate it over to the CLA. You can download the project files here and I encourage to follow along as I go through the different steps and considerations during the migration process.
Once you have ported your code over to the CLA and successfully built your executable, it’s time to debug. The CLA pipeline is unprotected and is debugged through the main CPU; you cannot debug code on the CLA in the same manner you would on the C28x. This module goes over the different aspects of setting breakpoints, single stepping and setting up CCS views when debugging the CLA.
In the previous modules you would have learned the workings of the CLA, the implementation of the ‘C’ language, and its unique method of debugging. This video deals with some of the common issues users face when writing code for the CLA. It is a compilation, and investigation, of some of the most commonly asked questions on the forums and should help you get to working code quickly.

There are a variety of tools to make development with the Piccolo family easier. These trainings provide an introduction to real-time features and software, as well as more detailed trainings on CLA.
