BLDC DRV10983 写不进EEPROM

1. Set SIdata = 1.
2. Write the desired motor parameters into the corresponding registers (address 0x20:0x2B) (see I 2 C Serial
Interface).
3. Write 1011 0110 (0xB6) to enProgKey in the DevCtrl register.
4. Ensure that V CC is at or above 22 V.
5. Write eeWrite = 1 in EECtrl register to start the EEPROM programming.
The programming time is about 24 ms, and eeWrite bit is reset to 0 when programming is done.

严格按着这个流程来操作的，读出来就是与写进去的不同

你是用自己的板子和code的吗？

移植官方的code，，都是正确流程
