esp8266/Arduino

Arduino IDE for ESP8266

Clemens Kirchgatterer

@everslick

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)

@nmenoni

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 ;-)

Bryce Schober

@bryceschober

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

I'm really only interested in UDP. I've looked at the iperf3 udp_send(), which is really simple. I'm doing that, but failing to get my iperf3 server interested.

nmenoni

@nmenoni

Hi! What is the recommended way to switch off the AP mode when I only need STA mode? (I use de board as station but I see the ESP ssid published). Thanks!

Martin Ayotte

@martinayotte

WiFi.mode(WIFI_STA); instead of WiFi.mode(WIFI_AP_STA);

nmenoni

@nmenoni

@martinayotte Perfect! Thanks

Stavros Korokithakis

@skorokithakis

does anyone know of a library that will let me easily call a function after some specified amount of time?

i.e. a one-shot timer that calls an already-defined function

Cristóvão Trevisan

@cristovao-trevisan

Ticker is already built-in, or ticker scheduler if the called function is time consuming (this is as stated in the docs, I've been using both in my project)
