Hi Team,
My customer is using HDC1080 and meets data reading error. could you help check?
here are processes:
1. wait 100ms after power up, write reset data: 80 02 80 00, HDC address is 0x80;
2. after 10ms, write config data: 80 02 10 00;
3. with 200ms cycle time, periodically reading data, logic analyzer get data 81 1F 80 FF FF..., as below:
Note: I2C frequency is 200K, as shown below. When reading the data of the specified register, after writing the register (for example, humidity: 80 01), and then run reading command (81), it will directly feed back NACK.
+ loop customer.
thanks a lot.
Best regards,
Yang
