Re: ESP32 lacks good small boards, dual base and stacking possibility. Why?

If you think there is a lack in the ecosystem, then maybe you should make your own boards to fill that gap and make money. :D

Re: Fast 16-bit parallel output?

This topic has come up several times. Just curious why espressif hasn't just added an example to the examples folder driving a LCD using this method.

Re: WROOM-ESP32 Custom PCB Troubles

The first thing that jumps out at me is the trace path from H1 pin 1 (GND) to the GND pin of the regulator. The only way i can see for the main GND to get to the regulators GND pin is this tiny sliver of a path which I have circled. IMHO you going to need much more trace with for the GND to the regu...

Re: ESP32 Task

I would guess that It's probably because loop() has a higher priority than task1.

Task1 has a priority of 0, which is as low as you can go. Thus it will get serviced last if other tasks are consuming CPU resources.

Re: Interfacing Encoder Switch with ESP 32

It could be a debouncing issue. I.E. when it transitions from high to low or visa-versa you will get several interrupts at once. You could try fixing that with a cap on that pin, or do it in software.

Can the WDT be routed to a GPIO pin

As most of us know when you starve the CPU core your going to get a WDT warning in the terminal.
I am curious if there is some kind of ISR hook or other call that can be implemented in code so that if it gets triggered I can toggle a GPIO pin.

Re: 5V tolerance

Going forward, do you guys think you'll officially support 5v tolerance? It would be a nice feature to have and make interfacing much easier in many cases. There is like a bazillion of devices out there that do this for super low cost. Ever since the first micros that went from 5v to 3.3v this issu...

Re: Unexpected ADC offset in ESP32

"The ADC should be configured before reading is taken." as per the docs, has this been done in your code ?
