Baseline assembly or C communication to all hardware 
registers and addresses. Most MCU vendors stop here.

At the heart of C2000 software is a set of 
memory-mapped bit fields and structures that make 
registers and register bits seem like simple variables.
• Bit fields can be manipulated without masking
• Flexibility to access a register as a whole or by bits
• Auto-complete field names in CCStudio
• View in CCStudio watch window just like variable

s

The peripheral API drivers are a high-level library of 
functions that wrap common tasks into parameter-based
functions.  
• C call-able functions that automatically set register
  bit fields
• Further reduces learning curve for new programmers
• Common tasks and peripheral modes supported

Source code and examples that enable easy device and peripheral initialization and configuration

 

Built primarily upon the bit field headers, the framework 
represents a system template and starting point for all 
applications.
• Function-based device initialization, allowing users
  to focus on application code 
• System management via state machines set to run at
  a specific frequency
• Ability to connect to an external GUI via SCI
• Simple switching between RAM and Flash eases early

• Pre-configured GPIO mapping
