Other Parts Discussed in Thread: LAUNCHXL-F280025C, DRV8323
Hello
We are using BOOSTXL-DRV8323RS with LAUNCHXL-F280025C
We followed Universal Motor Control Project and Lab User’s Guide and set the motorVars_M1.flagEnableRunAndIdentify to 1
We are faced with moduleOverCurrent fault 1
We have not connected motor or hall sensor to DRV8323
Our offset values set in user_mtr.h and data in expressions have a mismatch can you clarify it too
Thank you in advance
user_mtr.h
