CCS/TMS570LS0432: TMS570 Launchpad control feedback

Part Number: TMS570LS0432

Tool/software: Code Composer Studio

Hi,

i am developing a buck-boost converter and would like to use the TMS570LS0432 for the control. The issue is i have no idea how to implement the feedback for the control because this microcontroller has no comparator and no DAC and on my pcb which i is already designed and manufactured there are no external comparators or DAC. There are only the power stage, HALL-sensor and the voltage divider for output and input mesaurement. Could someone give some tips or reading material how i could solve my problem?
