Other Parts Discussed in Thread: DRV10987,
I can used the DRV10975EVB to control the motor speed by IIC .But it do not work in my appylication.
Following is my soft initialization:
1. 0X03 write 0X40 (enable EEPROM config)
2. EEPROM config
3.0X01 write 0X80 (IIC Speed contrl oveRide )
4.0X01 write 0X80
0x00 write 0x96 (write the speed value)
When get into the colosed loop,the Speed is 9360RPM about .And I change the start Speed Value conmand ,when get into the closed loop ,the speed is still 9360RPM about.But,When use the DRV10975EVB ,the same speed value conmand,Speed is 7280RPM.So i think maybe some mistake in my applicaiton ,I can't debug to the speed what I want .Please help me to check it,Also help to check the EEPROM Config whether it is suitable to the Motor,Thanks!
Attachment is my SCH and Motor Spec
