#44744 — Has anyone forthified ESP8266?

Hello!

I keep seeing nice hacks for this module. I haven't studied it enough to 
say anything useful about it but if I'm correct it is ARM with wifi.

To me it seems good starting platform for network connected Forth computer.

Has anyone done any investigation or any progress with it?

It's not ARM, it's a MIPS-descended instruction set from Espressif.

I doubt it, but there's a GCC port for it, so you could probably get any
of the C-based portable Forths running on it without too much trouble.

There's a similar but newer chip that's ARM-based:

Interesting part, very low power.  Seems hard to get info on it though, 
you have to register to get to the preliminary data sheet.  I wonder how 
the plan to distribute the chips.

Seeed Studio has some boards with it:

I think I replied to the wrong thread.  I was looking at a data sheet 
for a very low power processor from Ambiq called the Apollo.  Maybe it 
was mentioned in one of the comments to the hackaday post, but I can't 
find the reference.  Must be a different thread, maybe a different 
group, lol.

Actually I had hackaday.com open and I had read that article before. 
That's why I thought ES8266 being also ARM device.

I was going to write a Forth for it, and have four modules sitting on my desk.

But I have sofar not had the time or motivation to start writing a Forth for it.

I have set up the module as a wireless serial link for some FlashForth projects.

The module (or the software on it ) seems a bit unstable. The Wifi connection just dies after a while (= a day or so ). It also seems sensitive to too much traffic.

The ESP is quite power hungry. Almost 0,5 - 1 Watt used all the time.
Compared to very reliable BlueTooth modules the ESP uses about 5-10 times more power, so I rather stick to BT.

The CPU on it is an Xtensa LX106 CPU from Tensilica. A GNU toolchain exists for it. The C compiler and bootloader combo works just fine.

Any idea what is going on with that?  Crappy wifi implementation?  Bad
software?  Tons of mobile phones have wifi without using anywhere near
that much power with it on.  I linked in another post to a possible
alternative to the 8266, but I haven't tried either one yet.

I googled a bit and the ESP actually consumes max 0,5 W (170 mA@3V) when transmitting 802.11b at 17 dBm.
The 802.11n transmit consumes 120 mA.
Receive current is 50 mA.

Then there are some power-save modes that require appropriate software control.
These rely on periodically shutting down the RF tranceiver.

Nice to hear some work is done to it Flashforth (or at least thought) 
and the Graig Lindeys's forth was also rather interesting.

You are lucky. I need to reset it every two hours with my AVR 
thermometer toy. My motivation to ask forth for it was hoping getting 
more stable software :)

I haven-t even thought about it. Sounds bit stupid to heat that much 
device with WLAN controller.
