We're going to be talking about the ESP32 at 5pm PST / 8pm EST/ 9am Shanghai time (Feb 4th) on Friday the 3rd! PLEASE NOTE THAT WE NORMALLY DO THESE AT NOON PST, BUT THIS ONE IS AT 5PM PST.

@Sprite_tm will be leading the discussion.

More about the ESP32 here

We hope to do a few board giveaway, dependent on Chinese New Year shipping schedule!

    Hi sprite

    Sprite_tm says:14 minutes ago

    So, I'm kinda new to these kind of chats... what's the idea, I just start answering the things in the spreadsheets? Or are you going to pelt me with questions live? I'm open to both options.

    @Sprite_tm first intro yourself

    jaren havell says:13 minutes ago

    did you have to move to (china?) work for espressif or are you just there temporarily?

    (aaaand people will just pelt you with questions ...:)

    Is this question spreadsheet something we can see?

    Sprite_tm says:12 minutes ago

    Ah, thought the HaD people already did an excellent job in the HaD article announcing this :) but sure. I'm Sprite_tm, I started dabbling with electronics a fair few years ago, and at a certain point I decided to put the projects I finished up on

    Slightly less than two years ago, there was this mysterious 'WiFi to serial board' showing up on Aliexpress. I bought a few, and searched for the chip on it... it was an ESP8266 and it seemed programmable.

    Sprite_tm says:9 minutes ago

    Long story short: the Internet kicked in, the maker of the li'l chip was open to random hackers messing with the SDK and before long, people were developing programs for it. So was I. I developed a webserver and some other things. At a certain point, I got an invitation from the CEO: he lked my work and asked me if I would like to consult for Espressif, or maybe even come to Shanghai and work fulltime?

    Hi Everyone!

    Sprite_tm says:7 minutes ago

    Well, I chose the last option and haven't regretted it since. I have two titles at Espressif: I'm a Software Engineering Manager, and at a certain point I found a Technical Marketing Manager title sticking to the bottom of my shoe. In general, I'm more of a does-whatever-seems-interesting-or-useful guy, but we don't have a title for that :)

    Nacht Ritter says:6 minutes ago

    Prior to ESP8266, what did you dabble in?

    Sprite_tm says:6 minutes ago

    In that capacity, I worked on some ESP8266 projects, like the MP3 decoder, and when we started making the ESP32, I worked on some parts of the ROM, making FreeRTOS SMP-capable and general low-level esp-idf stuff.

    mumi says:6 minutes ago

    Hi Sprite_tm, thanks for being here today. Question: In terms of creating a shippable IOT product using the ESP-32, which are your preferred software stacks/dev setups? Does FreeRTOS rank well in this regard?

    Sprite_tm says:5 minutes ago

    I got my technical marketing title for allowing me to do random stuff as well: for example the NES emulator that runs on the ESP32 was developed with that hat on. If any, that's the type of 'marketing' I don't mind doing :)

    Adam Fabio says:4 minutes ago

    very cool!

    Sprite_tm says:4 minutes ago

    Nacht Ritter: See my site There's a whole slew of projects on there. For work, I used to be a software engineer at a broadcasting company, nothing too interesting I fear.

    baoshi says:4 minutes ago

    That's the way marketing should work I guess ;)

    Youlian Troyanov says:4 minutes ago

    when is the psram version coming?

    Jørgen Kragh Jakobsen says:3 minutes ago

    YEs @baoshi show dont tell

    Sprite_tm says:2 minutes ago

    mumi: Interesting question. I presume you mean FreeRTOS as opposite to Lua, MicroPython, Javascript, ...?

    Sprite_tm says:2 minutes ago

    We don't have a non-FreeRTOS C sdk for the ESP32, that's why I ask :)

    limor says:2 minutes ago

    @Sprite_tm Hi! Will Bluetooth classic be supported? It's mentioned in the datasheet, but not not clear if there is a timeline for support? And if so, would it support Bluetooth Audio and/or SPP? Thanks and keep up the great work!

    Sprite_tm says:a minute ago

    Youlian: We're waiting for the chips ourselves: they should be arriving from the fab very soon. I don't know...

Memory in ESP32

  Are you sure? yes | no

Sandeep Tara wrote 02/04/2017 at 11:54 point

my question has three parts 

A. I  liked an therefore used arduino because I could use a GPIO as input or output ( analog/digital) using ESP32 I can achieve the same?

B. How to use sensors designed for arduino (5V) ?

C. What is best way to have isolation for GPIOs used as inputs or outputs to real world?

  Are you sure? yes | no

There seems to be a great degree of variability in the makefiles. So far I've been able to find success with the three primary paths (ESP8266), dIrect makefiles within the home project directory, Eclipse, and Arduino.  I would prefer not to use the Arduino environment, even though it seems to work every time, as it's abstraction removes me too much from the hardware. So, would you care to make comments on how best to build a compile environment that is most flexible..  

Please put me down for a beer or two on me as esphttpd is a very generous contribution to the community.

  Are you sure? yes | no

My application is still pending. Is there anything we can do to push it through before the event? Thanks!

  Are you sure? yes | no

dedoooi wrote 01/31/2017 at 08:05 point

what is the main Difference between the esp8266-12E and the ESP32? 

I only uesd esp-12E for my projects.  Is there a reason to switch tu esp32?

  Are you sure? yes | no

MortenW wrote 02/01/2017 at 04:20 point

The Esp8266-12E is a "breakout" module using the ESP 8266 chip. the ESP32 is a newer version chip that will have its own break out boards, but the hardware is more powerful:  Dual core, faster clock, Bluetooth. +++

  Are you sure? yes | no

link please!

  Are you sure? yes | no

AVR wrote 01/31/2017 at 08:08 point

not sure if you are talking to me but here you go :)

  Are you sure? yes | no

AVR wrote 01/30/2017 at 04:52 point

this is going to be exciting, I have a few ESP32 board sin the pipline, Vento is already shared on here but more to come. 

  Are you sure? yes | no
