4.1.2.3.1.1 Objective

The objective of this build is to evaluate the peak current mode operation of the system, verify the DAC and ADC driver modules, verify the MOSFET driver circuit and sensing circuit on the board and become familiar with the operation of Code Composer Studio (CCS). Since this system is running open-loop, the ADC measured values are only used for instrumentation purposes in this build. Steps required to build and run a project will be explored.
