TMDSIDK437X: motor control project - ethercat sync

Expert 1130 points
Part Number: TMDSIDK437X

hi,

at the motor control project , at foc_pwm.c file the below highlighted comment is found.

can you help me understand which IDK pin I should connect to epwm3_synci ? maybe you can point me out the the relevant document ?

I need to find the ethercat sync output...

(I am using the TI code @ beckhoff stack)


#ifdef ENABLE_PWM_SYNC
#ifdef SYNC_ECAT_PWM
/* ECAT SYNC has to be connected to PWM3 SYNCI in h/w */
/* Route PWM3 syncout to PWM4,5 synci */
CSL_epwmTbSetSyncOutMode(SOC_PWMSS3_REG, CSL_EPWM_TB_SYNC_OUT_EVT_SYNCIN);
