Options for HTTPS and WSS server

I have non-secure websockets ( https://github.com/ThomasBarth/WebSockets-on-the-ESP32 ) working with the esp-idf https server example. The problem is that browsers won't allow javascript to access non-secure websockets from https. Any ideas on the simplest way to add WSS? I'd prefer not to use mongo...

Re: slow rising signal and edge triggered interrupt

The slow edge won't be a problem for triggering an edge interrupt as long as the the Vil/Vih thresholds are met. The problem may be multiple interrupts as the signal slowly transitions through the region between Vio x 0.75 and Vio x 0.25 (or vice-versa). Noise in the system and inside the ESP32 may ...

ADC1 operation affecting GPIO27 - chip issue?

I've got GPIO27 configured as a digital input (with both an external pull-up and internal pull-up enabled), but when I perform ADC1 conversion operations, IO27 glitches 'low' for about 6us. With a 10K pull-up, the glitch is about 1V (drops to ~2.3V). With a weaker pull-up, the glitch is low enough t...
