Configure Control Peripheral and ADC Interrupt With Sysconfig

Sysconfig is a GUI-based configuration tool. It significantly simplifies the configuration of control peripherals and interrupts. The items inside Sysconfig are described in a very intuitive way. After the configuration is completed in Sysconfig, configuration program will be automatically generated and connected to main function during build. They are stored under the following files under a folder named "Generated Source". It is worth attention that the content of those files will be refreshed after a build with Sysconfig. It is fine to copy program from these files and reuse in other parts of the application program. More details on Sysconfig can be found from SDK documents. In the following parts of this section, the focus is on how to setup control peripherals and interrupt for a traction inverter.
