Getting the uptime

Request for HTTPS support

Hello It seems that this forum currently only supports plain HTTP, and not encrypted access using HTTPS. I find this very unfortunate, as this means that my username along with my password will be transmitted as plaintext, and it will thus be very simple to intercept. Have you any plans regarding im...

Re: Calibrating ADC

I second this.
I will be using the ESP32 in a project this spring, which will involve the using the integrated ADC.
Are you able to provide some kind of documentation on the non-linearity of the ADC?
