ESP-WROOM-32 ADC VREF Calibration

Postby connor » Tue Nov 14, 2017 10:49 pm

Hello,

Regarding the ESP 32 ADC VREF issues, is VREF currently being measured at the factory and burned into the efuse?

Here is a quote from igrr on GitHub:

"Large scale: new chips produced starting from (some date)(1) will have their V_REF burned into efuse at production. Calibration code will automatically pull this value from efuse."

Is there an ETA on this being in place?

Thanks,
Connor
