@everslick that's what I wanted to know, thanks!

Hello all, a question, I'm using the (virtual) EEPROM of esp8266, with the:
EEPROM.begin (size)
command. Ok, and what is the maximum size I can use? I usually see examples using 512, but what would be the limit?

@everslick
4096

@everslick
OK thank you.

But using the other system sppifs (I have not yet used this method) would I have more bytes to use?

Clemens Kirchgatterer
@everslick
yeah, much more
rodrigocirilo
@rodrigocirilo
@everslick
Is it too complicated to use sppifs or is it equal to eeprom?
Clemens Kirchgatterer
@everslick
@rodrigocirilo completely unrelated. SPIFFS is a filesystem, where you have the usual FILE operation API (open, read,write,close,...)
have a look at the examples.

I'm having issues obtaining the fingerprint a la https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/client-secure-examples.html . I'm in Chrome in OS X. I'm visiting https://api.github.com, then opening the inspector > Security > View Certificate (on overview) then expanding down to the last line & copying SHA-1 of *.github.com. When I connect, I get the "certificate doesn't match" error as per the code in the tutorial. Am I copying the wrong thing?

@Sleepy105 can you try put generic module esp8226 in arduino ide and put reset method nodemcu
@Sleepy105 gpio 0 should low

@Sleepy105 I give you 4 links , if you want try again:
GPI0 It is D3

hey everyone
i would like to get this library working with the ESP: https://github.com/zendes/SBUS/blob/master/SBUS.cpp
when you instantiate it, you pass it Serial
it uses .available, .read, and .begin
i should be able to pass it a softserial instance as well, right?
Stavros Korokithakis
@skorokithakis
what's the most popular/best softserial library right now?
Stavros Korokithakis
@skorokithakis
hmm, i'm trying to pass the SoftSerial instance and i'm getting this error:
lib/SBUS/SBUS.h:14:23: error: expected ')' before 'serial'
SBUS(SoftwareSerial serial) : _serial (serial) {}
Stavros Korokithakis
@skorokithakis
this is too complicated... maybe i can just connect an arduino to the esp
Stavros Korokithakis
@skorokithakis
does the ESP have a second serial RX?
Stavros Korokithakis
@skorokithakis
can i use an nmos instead of the transistor here? https://raw.githubusercontent.com/zendes/SBUS/master/SBUS_inverter.jpeg
damnit
Stavros Korokithakis
@skorokithakis
yay, it works (sometimes)

Hi! I need to add wired connectivity to my esp8266. What are the options?
I have a ENC28J60, Can this be used?
Thanks!
nmenoni
@nmenoni
any suggestion?
Clemens Kirchgatterer
@everslick
I2C, ISP, RS232 ?
the ENC28J60 has an SPI interface, so for sure it can
nmenoni
@nmenoni
@everslick Thanks! Some clue to which alternative would be the most stable? I have read that the ECN28J60 is not very stable for arduinos, but I do not know if it applies for ESP8266 since it has more RAM
Stavros Korokithakis
@skorokithakis
hey, @Makuna, about your neopixel library, will I mess stuff up if I Serial.println() while I use the lib, since it's connected to RX?
i guess not, since it's RX, but maybe i shouldn't connect to the serial interface
bobcroft
@bobcroft
@nmenoni Hi look up Luca Dentella's blog he has done some work with the ESP and the ENC28J60 and made notes on his blog.
Michael Miller
@Makuna
@skorokithakis There is note in the Wiki about this. The serial must be "begin" before the NeoPixelBus, so that the use of the RX pin is used for NeoPixels; so you can print, but you can't recieve
@skorokithakis And, I do have my own gitter channel ;-)
Stavros Korokithakis
@skorokithakis
@Makuna ah, I looked for quite some time but didn't find info either about the pin or the serial, you might want to add a link to the "get started" section
And I keep forgetting about your channel 😛
Michael Miller
@Makuna
@skorokithakis Read this section. Getting started would be a nice addition to the Wiki; but really only the Esp8266 platform has so many "nuances" to using it.
Stavros Korokithakis
@skorokithakis
@Makuna ah, that's what I needed, thanks. Yeah, currently that section is a bit hard to discover, though 🙁
Stavros Korokithakis
@skorokithakis
can someone point me to the docs for the servo lib? I found makuna's commit, but no docs that i can see so far...
or is the ABI the same as the official arduino?
hmm, it might be
Stavros Korokithakis
@skorokithakis
it is indeed!
Michael Miller
@Makuna
Yes it is ;-)

anyone have an idea how I would implement an iperf3 client?
