Browse the TI C2000 Processors Library

• Click on Library Browser in the SIMULATION tab.

• Browse to Simulink Library Browser -> Embedded Coder Support … -> F2837xD
• Library F2837xD is the library (lib) to be used for the microcontroller.

Adding Memory Blocks

Adding "Input" Memory Blocks

• Browse to Simulink Library Browser → Memory Operations.

• Add a Memory Allocate block.
• Add a Memory Copy block.
• For clarity, let rename them:
  • Rename the Memory Allocate block "Save_Input".
  • Rename the Memory Copy block "Read_Input".

• Memory Allocate Block Parameters: Create an “input” variable.

• Memory Copy Block Parameters: Configure to read input variable from CCS.

Adding "Output" Memory Blocks

• Add another Memory Allocate block.
• Add another Memory Copy block.
  • These blocks will let us see the “output” variable in CCS by storing its value.
• For clarity, let rename them:
  • Rename the Memory Allocate block "Save_Output".
  • Rename the Memory Copy block "Read_Output".
• Add a multiplication block and connect the Read_Input and the Read_Output as showed below.

• Memory Allocate Block Parameters: Create an “output” variable.

• Memory Copy Block Parameters: Configure to read output variable from CCS.

Adding a "Gain" Variable and Initialize it to 1

• Add another Memory Allocate block.
• Add another Memory Copy block.
  • This block will let us see the “gain” variable in CCS by storing its value.
• For clarity, let rename them:
  • Rename the Memory Allocate block "Save_Gain".
  • Rename the Memory Copy block "Read_Gain".
• Memory Allocate Block Parameters: Create a “Gain” variable.
  • Check the Initialize memory box.
  • Enter "1" as the Initial value.

• Memory Copy Block Parameters: Configure to read Gain variable from CCS.

Set the Port Data Types

• Set the Port Data Types from DEBUG -> Information Overlays -> Ports -> Base Data Types
  • This is to show data types for the signals, as shown in the final image of this page.
  • We have to define data types when we use memory allocate and memory copy blocks above.

• The finished model looks like this.
