HDC3022: List of Valid Configuration Values to Override the Default Device Power-On/Reset Measurement State

Riya Sidharth

Part Number: HDC3022

Tool/software:

Hi,

I have a question regarding Table 8-4 'List of Valid Configuration Values to Override the Default Device Power-On/Reset Measurement State' for the HDC302x. It is mentioned in the datasheet that the configuration data is 2 bytes and the CRC is 1 byte. However, the first and second column names in the table are given as CFG (MSB) and CRC (LSB). It is to be noted that CFG (LSB) value is not given.

1) How can we get the value of CFG(LSB)? Is it a typo in the second column as it is mentioned as CRC(LSB). I suppose the CRC needs to be calculated based on the MSB and LSB of CFG data.

2) If the second column is actually CRC, how is it calculated? What is the CFG(LSB) value for this CRC calculation?

Best Regards,

Riya

HI Riya,

You are correct, this table has typos that make it difficult to understand, so I am very sorry for the confusion. We are currently in the process of updating the datasheet with the proper table. Please use this corrected table instead:

As you can see here, the CFG MSB and LSB columns are present, and CRC is just calculated by feeding those into the normal CRC polynomial.

I hope this helps.

Regards
