Part Number: HDC2021 We have tried to get a temperature reading from the device over the I2C bus, but always read zeros.
Confirmed what we are reading using a scope on the clock and data signals. Also, we read the expected data from registers 0xFC, 0xFD…
Hi Yuxi,
We typically don't recommend user's solder the HDC devices through means other than reflow, but yes this can be done. I would recommend using the HDC2021 in this case. It is functionally identical to the HDC2080, but has a removeable tape cover…
Hi Onawa-San,
If a stop is sent in the middle of the transaction, the HDC2021 should return to a listening state and be ready for the next transaction. Please note that they will have to start the transaction over from the beginning if they send a stop…
Part Number: HDC2021 Hello,
The HDC2021 datasheet contains conflicting information in regards to reflow. Section 3 says that the tape cover provides protection during PCB board wash. However, section 10.1.1.2 states that no-clean solder paste is mandatory…
