I think the reason why your USB2TTL is disappearing from the device list is simple -- the ESP8266 requires about 300mA of current, and that's more than your USB2TTL can provide. Either the computer detects overcurrent, and shuts the port off, or the USB2TTL shuts down by itself, to protect your comp...

Yes, I used the -m8 option, and also tried the -m32 option, without any improvement. I desoldered the board and replaced with a different one, with the same result. Then I tried the desoldered board directly. They all have the same problem. I also noticed, that they restart at random even when not d...

I have tried both the v1 and v2 version of the alpha firmware successfully on many boards, but I'm having a hard time with this one. It's an ESP-12 module which I have already soldered onto a printed circuit board for my robot. I originally programmed it with the Arduino IDE, but now I wanted to try...

There is a very cool library for ESP8266 that uses its I2S hardware, with DMA, for driving neopixels. It doesn't let you choose the pins freely, but it's blazing fast: https://github.com/cnlohr/esp8266ws2812i2s

Hi Roberth,

this error has been reported before here, it happens on macs which use non-standard version of bash, which doesn't understand the "-e" argument to the "echo" command, so it's getting echoed together with the string.

To exit screen, use "ctrl+a ctrl+k" or "ctrl+a ctrl+K" (the latter if you don't want a confirmation question).

Fair enough.

That looks about correct. Don't forget to indent the body of the loop.

But it kind of makes sense to keep the documentation in sync with the code in the repository. It's a kind of tradition (or at least basic assumption) in the open source (and not only) world, that the documentation you get with the code applies to that code, not something completely different that yo...

That is normal. GPIO16 is special and very limited, anything more advanced won't work with it.
