Anyone interested in Arduino Environment?

[ESP_Me-no-dev]

I've translated over just about everything over from ESP8266.

I have the following hardware working:
HSPI and VSPI SPI busses attached to any pin
UART 0 and 1 (0 is attached to pins 1 and 3) UART 1 can be attached to any pins
pinMode/digitalRead/digitalWrite/attachInterrupt
analogRead (duh) SDK functions are exposed (same goes for touch pads)
4 types of PWM! SigmaDelta, LEDC_HF, LEDC_LF and the old style based on timer (currently the one attached to analogWrite)
ccompare and 1 hardware timers with Interrupts
pinMatrix functions for easy signal routing (those are mostly the same as the ones in the driver lib)

Mostly everything should work the same as on ESP8266. Some methods are removed from the ESP and WiFi classes as they are not available anymore.
UDP Multicasts are not build into lwip yet so any service that depends on them would not work (mDNS, SSDP and such).
ArduinoOTA is also not working yet as it requires different rom layout.

Toolchains that I have tested and are working:
Mac OS X: http://static.ficeto.com/xtensa-esp108-elf-osx.tar.gz
Linux 32: http://static.ficeto.com/xtensa-esp108- ... x32.tar.gz
Linux 64: http://static.ficeto.com/xtensa-esp108- ... x64.tar.gz
Windows 32: http://static.ficeto.com/xtensa-esp108-elf-cygwin32.zip << Needs https://cygwin.com/setup-x86.exe installed (defaults are fine) and "C:\cygwin\bin" added to Path
Windows 64: http://static.ficeto.com/xtensa-esp108-elf-cygwin64.zip << Needs https://cygwin.com/setup-x86_64.exe installed (defaults are fine) and "C:\cygwin64\bin" added to Path

To compile sketches you need one of the toolchains above or to build it yourself. The toolchain should go inside the "ESP31B/tools" folder.
For Windows, Python2.7 needs to be installed and in Path.

I include inside my Async TCP and Web server as well (regular blocking server and client are there also) for those that want to run full speed and handle more than one client at a time.

Hi,

Can you deploy also for ESP32 ?

Br, Xatax

[ESP_Me-no-dev]

When it's available all we currently have is ESP31B (look at markings at the module).
So it works on what we all have, will rework it for ESP32 (hopefully together with @igrr) when it's released.

I'm definitely interested.

I would like the Arduino environment too.
That makes it easier as I use a Mac.

nice work! thanks!
give you us the "ESP31BmDNS.h" too?
just in time is missing..

best wishes!

  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://www.arduino.cc

  This example code is in the public domain.

good catch on the warning. No clue on the segmentation fault though. Any chance there is something different on our toolchains?
I compiled mine on Mac using the instructions provided by espressif.

have tested yours just in time with the compiled version for windows taken from Unofficial Development Kit for Espressif ESP32 (Windows)

had posted Mikhail, because this goes wrong too:

Code: Select all

..
uint8 temper;  // result in fahrenheit
float celsius;    // conversion in Celsius later

celsius = ( temper -  32 ) / 1.8 ;
..

but in linux build version named in espressif github and like you refering
there is no segmentation fault though. so i think Mikhail must go on in this again
think perhabs usual suspects are versions of : gmp & mpfr

thanks for your fast responding!
( and help in SPI pins )
best wishes
