Re: Differences between GPIO pins
This is the general functionality overview. What I have problem with is some odd behavior of some GPIO. Like one-wire with neopixel LEDs - some GPIO "just work" while other sometimes also give some interference. Adafruit OLED aside of SPI uses two IO pins extra and like GPIO 26, 27 did not work corr...

Differences between GPIO pins
So GPIO 34-39 and input only. Internal flash 7-10 are unavailable (yet exposed on the board). Are there any other differences or limitations of other GPIO pins? Like for one wire or CS for SPI devices?

Re: Where can I purchase high quality ESP32 development boards with the most recent version of silicon (rev 1, I believe
criticisms I have launched against the CEO of Espressif. I wonder how Microsoft CEO stands all that criticism... oh what - their software is provided "as is" and with no responsibility on how it works for you. The same with hardware. If you use ESP32 module the Espressif is not obliged to do anythi...

Re: What would you like to see in The Next Chip?
Support for MIPI DSI displays could be handy (most tablet, phone alike displays). Some STMs support it. Alongside other multimedia/image/camera features it would likely have to be a specialized chip on its own.

Re: ESP32 + OV5640 Camera
Don't have any numbers but if the radio throughput would be the limiter then you could change JPEG compression ratio and get that framerate. In general such cameras don't give superb image quality and with lossless JPEG they generate much less data than machine vision cameras with raw formats. Short...

Handling of additional SPI Flash chips
Is there an option to use ESP32 SPI Flash functions in the context of additional Flash chips (that aren't meant to be used by ESP32 like the default Flash chip is)? or if not - is there a library that can do that already? Edit: https://github.com/Marzogh/SPIFlash this seems to be working (tested on ...

Re: Simple audio with DAC
Didn't used delayMicroseconds - will have to check that out.
