3.1.1 Devcie Initialization

In this project, the TI SysConfig tool is utilized for the initialization and configuration of all device peripherals. The board_init() function, invoked within the "AHB_main.c" file, links the application software with the configuration parameters defined in the "c2000.syscfg" file.

The SysConfig file is device-specific to the F28P55x family and serves as the central repository for all peripheral and pin assignments. Through this configuration, both analog and control peripherals are initialized in a consistent and maintainable manner.

Specifically, the following modules are configured using SysConfig:

  • Analog peripherals: ADC, ASYSCTL, CMPSS

  • Control peripherals: ePWM, CLB

  • System peripherals: GPIO, X-BAR, Interrupt, and CPU Timer

This approach ensures deterministic initialization at startup, reduces manual register configuration errors, and provides a graphical interface for easy modification of peripheral mappings. Detailed descriptions of each configured peripheral and its role in the control architecture are provided in the subsequent sections.
