HI,
We encountered an unknown I2C NACK issue. Based on the waveform as below, should we enable VCC after all the other signals arrive the stable voltage level? What else can we check?
- Channel1：VCC
- Channel2：I2C_EN
- Channel3：VIO_SEL
- Channel1：VCC
- Channel2：I2C_EN
- Channel3：A0
- Channel4：A1
Thanks,
Antony
