B4R Question ESP8266

[Michael1968]

Hi Erel,

i want to upload a blink example to my ESP8266

I get this error:

I use a Adafruit Huzzah and a Nodemcu V1.0

I have also tried with a NodeMCU and it do not work.

I've haven't yet tested B4R with ESP board. I'm waiting for my board to arrive.

This specific error can be solved by commenting line 54 in libraries\rCore\B4RArduino.cpp

Thanks Erel, after commenting line 54, the program can be compiled and load into the board. but the I constantly receive a message on the Log (every seconds I guess)

Anyway I will wait for you to receive your board and make your own test. Thanks a lot.

If you want to programming using arduino IDE using FTDI usb to serial cable and 5V to 3.3V Level voltage converter. and add "http://arduino.esp8266.com/stable/package_esp8266com_index.json" into Additional Board Manager URLs field in the Arduino v1.6.4+ preferences. or link "http://www.instructables.com/id/ESP8266-as-Arduino/" for reference...

Hi Erel,

did you receive your board???

Best regards
Michael

 

[Erel]

Yes. I received this shield: http://www.ebay.com/itm/ESP8266-ESP...opment-Board-for-Arduino-UNO-R3-/121818143422

I did try to create a wifi library that will work with it, however I wasn't able to get it working at all (trying from the Arduino IDE). I will try it again in the future.

 

[Toley]

Hi Erel, the examples that come from this library are working very fine. I don't have the exact same shield as you but it works with an ESP8266-12 and a Node-MCU who holds the same chip as yours (ESP8266-12E).

I would also be interested in seeing ESP8266 support in B4R. I have a WeMos D1 R2 (WeMos D1 R2 WiFi ESP8266 Development Board Compatible Arduino UNO).

The board offers much more memory and runs at 80 MHz, I think, and it's cheap. Although, it may lack some features of the Arduino.

I've actually hardly looked at the board, but I think it may make a great updated platform for things similar to what the Arduino can do.

Barry.

 

[Erel]

I've ordered it now...

FYI: A good reading about the ESP8266 is Kolban’s book on the ESP8266. It's for free (PDF).

 

[viriato]

Hi,
This will be great if you can support ESP8266 , it will be a big step for IoT and supporting MQTT

Thanks

Success with Blink
had to add one line at 79 in rCore/Scheduler.cpp before pollers.runAll();

yield(); //avoid watchdog reset
pollers.runAll();

 

[tirpitz]

success also with Serial output.
Here is my changes in rCore/B4RArduino.cpp line 48 -> 58

#ifdef B4R_SERIAL
stream.wrappedStream = &::Serial;
// #ifdef _VARIANT_ARDUINO_DUE_X_
::Serial.begin(BaudRate);
/* #else
::Serial.begin(BaudRate, Config);
#endif
while (!::Serial) {
;
}
*/

 

[inakigarm]

@tirpitz , what kind of ESP8266 device are you testing? (esp8266-1,esp8266-12,NodeMCU, ...) ?

 

[tirpitz]

This one:

 

[rwblinn]

Curious: How is this board integrated in the Arduino IDE and is the board also listed in B4R Board Selector?

Reason for asking:
Added ESP8266 Boards into the Arduino IDE 1.6.8 using "http://arduino.esp8266.com/stable/package_esp8266com_index.json" (Additional Board Manager URLs field).
But when opening the B4R Board selector, these additional boards are not listed.

Probably should start a new thread for this.

 

[Erel]

I'll explain. B4R tries to extract the list of boards from Arduino IDE.

During the beta there were cases where this step failed for (currently) unknown reason. The workaround is to provide a static list of boards when it fails. The list is stored in boards.txt in the installation folder.

You can replace the file with the one attached. It includes the ESP boards.

 

[rwblinn]

Thanks = Done.
Steps taken:

• Attached & selected board NodeMCU v1.0 with upload speed 115200.
• Changed core library scheduler.cpp as stated in post #14.
• Changed core library B4RArduino.cpp by commenting out lines 50 and 52-54.
  
• Got the Blink Example working on a LED connected to pin D2 which is GPIO4 of the NodeMCU. In B4R defined as Private LEDPinNumber As Byte = 0x04

Followup question:
Is it possible to add as permanent fix in B4R, an additional conditional define for the ESP8266 for core lib B4RArduino.cpp? or any hint if this can be done via B4R code.
I am not sure, not tested yet, as the changes will also work for the Arduino boards.

Appreciated
