8 Microcontroller Resources

The F2802xF microcontroller resources required by the InstaSPIN libraries are discussed in detail in the

TMS320F2806xF, TMS320F2802xF InstaSPIN-FOC/TMS320F2806xM InstaSPIN-MOTION User's Guide

(literature number SPRUHJ1).

Specifically for the library implementation and where the code is loaded and executed from, the following

resources categories are discussed in this document:

• CPU Utilization

• Memory Allocation

• Stack Utilization

• Digital and Analog Pins Utilization
