A short excerpt from HV_Solar_DC_DC-Main.C  about the included libraries …

/----------------------------------------------------------------------------------
//  FILE:           Solar_DC_DC-Main.C
//
//  Description:    Solar MPPT DC-DC Stage
//                  The file drives duty on PWM1A and PWM2A for DC-DC boost stage on the HV Solar
//                  MPPT board. It also generates 50% duty with dead-band on PWM3A & PWM3B for
//                  the LLC stage on the same board.
//                  C28x ISR is triggered by the PWM 1 interrupt
//
//  Version:        1.0
//
//  Target:         TMS320F2803x(PiccoloB),
