Hello @KevinHSU,

Thank you for your question.

  • What is the value of ODR_T_BATCH_[1:0] in FIFO_CTRL4 (0Ah) ? If it's 00, the temperature is not batched in FIFO (default). You need to select a data rate (eg : 11 for 52 Hz).
  • Also, can you check the TDA bit in the STATUS_REG (1Eh) ? It indicates if new data are available or not.

Best Regards,

Pierre

Hellow Pierre

The FIFO_CTRL4 (0Ah) value is 0x30 , so ODR_T_BATCH_[1:0] is "11" , and I check the 1Eh still 0x00 .

Do you have another suggestion

thanks

Hello @KevinHSU,

  • What is the value of TAG_SENSOR_[4:0] in FIFO_DATA_OUT_TAG (78h) ?
  • And are you using the interrupt on INT2 pin, what is the value of INT2_CTRL (0Eh) register ?
  • Have you always respected the AMR ?

Best Regards,

Pierre
