The STSW-DABBIDIR source code firmware package represents the control section of STDES-DABBIDIR. By
using hardware section configuration of the FW, different hardware configuration proposed by the CTMs can also
be supported. The main parameters such as switching frequency, dead time, sensing parameters, and magnetics
section can be customized.

How to operate the STDES-DABBIDIR

This section provides examples of operating modes. Several setups are proposed to help evaluate and become
familiar with the various features of the reference design.
7.6.1 Mode 1 – open loop, driving check
This test is for the driving section of the application. PWM signals are generated by HRTIM according to the
STM32CubeMX peripheral configuration.
Dead time and switching frequency are managed by "PWM_FREQ", "DPC_DT_DAB1" and "DPC_DT_DAB2" of
"DPC_Appplication_Conf.h" file.
No high-power equipment is required during this test.
MCU and gate driver section phase shift between primary and secondary can be verified during this test.
