3.2.1 Lab 1

This lab is meant to be run on the control card and the docking station.

Set the project to Lab 1 by changing the Lab Number in the <tinv_settings.h> or main.syscfg file, (this is changed with the powerSUITE GUI when using the powerSUITE project). Most users can skip to Lab 2 to begin test flow.

#define TINV_LAB 1

All the other options can be left at default, for now, in the user_settings.h file

#if TINV_LAB == 1
#define TINV_TEST_SETUP TINV_TEST_SETUP_RES_LOAD
#define TINV_PROTECTION TINV_PROTECTION_DISABLED
#define TINV_SFRA_TYPE TINV_SFRA_CURRENT
#define TINV_SFRA_AMPLITUDE (float32_t)TINV_SFRA_INJECTION_AMPLITUDE_LEVEL2
#define TINV_POWERFLOW_MODE TINV_INVERTER_MODE
#define TINV_DC_CHECK 0
#define TINV_SPLL_TYPE TINV_SPLL_SRF
#endif
