Formula to calculate ADC_VREF fuse
Posted: Mon Mar 12, 2018 6:01 pm
Hi,
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 espefuse.py?
The following doesn't work
./espefuse.py --port COM21 burn_efuse ADC_VREF 1127
Thanks,
Gino
