what we know about:

a) in this version there is no 5 GHz but it is on the work

b) in this version is USB

c) TinyBASIC port in ROM?
no in this not but there is plan 4 versions of based on the new architecture

d) it is a Tensilica / RISC V are in the pipelines.

e) there are beta user / request possible :)

f) there is no CAP1 and CAP2 any more



...still in edit work this post ...

best wishes

Any bets on
usb rom bootloader
Encrypted psram
Improved adc
Battery backed rtc

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 nicely on the same space as it currently occupies on the ESP32.

Code: Select all

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}

@WiFive
today was FCC alert with ESP32 and ESP8285

the last named is a new modul design based at ESP8285 - it looks like "usb" :) for flashing, booting (SDIO ) and so on 8-)

I can imagine that here cnlohr's USB1.1 will be running :) or I even say, that it was explicitly intended :) :) (Test series)

And possibly USB host mode? Would be nice, to hook up a LAN9415 to it :D

Code: Select all

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}

also:
ESP32-EYE
the ESP32-D0WD is on left and right side 14 pins and top and bottom 10 pins
ESP32D0WD_5.5.jpg

so if we compare this Chip with Chip7 possible size

i think it can be not to be so much bigger be the chip7

he looks thicker (higher)
perhabs we have an port expander eMbedded for more GPIO pins and "coded" USB instead Cap1 Cap2 .. so or so ..

Just to temper expectations a bit: this is likely not going to be the top-of-the-line powerhouse that you guys think/hope it will be, as seen in the posts in this topic. Not saying we're not working on one of those :) but this is not it. (It does have a few picks from the ideas of the 'what would you like to see in the new chip' topic inside, though.)

What we need is a workhorse, a better allrounder than the ESP32 is, at roughly the same price. Seems like it is.

Congratulations on using RISCV: cheaper, higher clocks, lower power, Rust support and an easy upgrade path.

If it delivers this chip might become everybody's preferred micro-controller, a blockbuster.

Tiny basic? A WebAssembly _interpreter_ would let us to download and then run code from many languages, dynamically.

It was previously posted by an ESP engineer here that more cores weren't in the planning for the current chip because memory bandwidth would make them pointless.

I hope there's vector operations/instructions for this - it'll be easier to handle complex numbers and some graphics too. :D
