... but all in all it's not meant as a flagship powerhouse.
From your wording it seem that Espressif is working on a flagship power house?

Re: espressif's "Chip7 2-2-A" spotted in the wild

Well, 240MHz is well enough. Although, in this case FreeRTOS could be excluded entirely, and maybe, the chip's resources could be used more efficiently. However I still think that in more complex cases FreeRTOS or something simillar can still be a good option. One request for the devs: Please make a...

I think the I2C slave implements some kind of clock stretching now, so there's at least half a ✓ more :P

Will it be able to load and run programs from PSRAM?

Also An Interview ( 44:00 ) to Ivan of Espressif in Shanghai - ... listen to the podcast best wishes rudi ;-) Just listened to the Ivan part of the podcast. I giggled when he mentioned how difficult was the TRM. I guess here the bigger problem was that this document is english and not chinese :D Bu...

Any bets on
usb rom bootloader
Encrypted psram
Improved adc
Battery backed rtc
And possibly USB host mode? Would be nice, to hook up a LAN9415 to it :D

Re: espressif's "Chip7 2-2-A" spotted in the wild

Not quite sure looking at picture - but is the chip size 2x bigger? More cores? ) Well, in the ESP32, 75% of the chip size is the RAM :D And that is just a 2mmx2mm silicon die. So I'm guessing the bigger chip size is mostly due to it having more RAM, and more IOs. More cores and stuff can just fit ...

Re: [info] ESP-EYE DevKIT from Espressif spotted in the wild and i got one :)

Interesting, very interesting indeed. There's some information about the board here too. Most useful post. I have mine untouched so far, cause I don't know how to use it. Now I do :) The link is broken, the information is now here :) I found the correct link eventually :D I only need to know that i...

Re: ESP32 sketches take more space than Arduino Uno

The 2 chips are very very different! The uno is an 8bit device, the ESP32 is a 32bit device. So in a nutshell, an instruction and a simple variable in the uno only takes up 1 or 2 bites of memory, while in the ESP, 1 instruction and one variable takes up 4bytes. About 4x the size Additionally the fu...

Re: Gripes on ESP32/ESP-IDF

Again and again... Not only that your hardware is badly designed. You don't even know how to test it and how to write drivers for it. (And your docs are incomplete too) 2 years on the market and your SPI drivers are still not working. 2 years on the market and you still don't know about all HW issu...
