Formula to calculate ADC_VREF fuse

Postby ginodecock » Mon Mar 12, 2018 6:01 pm


Using the function adc2_vref_to_gpio(GPIO_NUM_25) I was able to measure the internal reference voltage.

In my case it is 1,127V.

What is the formula to calculate the value that I have to enter for the efuse using

The following doesn't work
./ --port COM21 burn_efuse ADC_VREF 1127
