MCT8329A: 使用STM32的I2C接口，无法成功写入MCT8329A的EEPROM

I didn't express myself accurately just now, 0XA1 is the result of not adding FFFF to the initial value, adding FFFF makes it 0X7A, what I don't know is using I2C to write the data CRC, which one should prevail? I always can't write EPPROM successfully, every time I write EPPROM data, and then read RPPOM, I found that I didn't write it successfully. The following is a list of the CRC's for writing data using I2C.

:<

I've made sure that the regulator's AVDD and DVDD outputs are 3.3V and 1.5V. And make sure that the FG and nFAULT pins are pulled up to 1.8V ~ 5V via external pull-up resistors.

  I'm adding some information, I don't use CRC, I use the following data, and I can't write the successful data, I use the oscilloscope to observe the waveform of I2C, and the MCT8329A does get the ARK signal, which proves that there should be no problem with the I2C program.
0xc0 0x50 0x00 0x80 0x20 0x20 0x20 0x20 0X20

您好，

      从您的描述来看，I2C通讯时序是正常的。

      EEPROM写入的方法请参考这个帖子的示例代码。

Hi, I have solved the I2C communication and configuration problem before you replied to the message, now my motor always starts and stops after one or two revolutions and the fault shows unsynchronized. I lowered the duty cycle and current of the IPD and still can't fix it. I always have the problem of unsynchronized motor, the motor fails to start with high probability, is there any relevant information for the problem of unsynchronization?
