ADS1259：how to do ads1259 calibration?

ming li50749

Part Number: ADS1259

Hello everyone!
I am using ads1259 and get the data, but I don't know how to do the calibration. I don't understand some of the 27 pages in the datasheet.

Step 2 starts the conversion. Shouldn't SDATAC be sent before sending the OFSCAL or GANCAL command? suppose i use RDADC mode?

Hi Ming,

I would recommend putting the ADS1259 into SDATAC mode before issuing the calibration commands.

RDATAC mode is only for reading data without the RDATA command. Also, I believe that while the ADC is in RDATAC mode that it only looks for the SDATAC command, and may not respond to other commands.
