Just started working with arduino and esp8266.
I configured the Arduino IDE adding: http://arduino.esp8266.com/stable/package_esp8266com_index.json to preferences.
Installed esp8266 by ESP8266 Community version 3.1.1 from board manager
Selected Generic ESP8266 Module board for doing some tests
But when i click on "Verify" this error pops up:
FileNotFoundError: [Errno 2] No such file or directory:'C:\Users\massi\AppData\local\Arduino15\preferences.txt'
exit status 1
Error compiling for board Generic ESP8266 Module.
I have no idea how to fix it
If anyone can help thanks
I tried reinstalling IDE and boards but still...
Fixed.
Unistalled then installed from arduino original website.
Problem was downloading the app from the microsoft store, sometimes those apps are buggi or can generate some problems in the file system.

Intro
Yesterday we were trying to update the firmware of our 3D-printer a Tevo Tarantula i3 The printer was running Marlin 3D Printer Firmware.
We installed a new module a TL-Touch Sensor, a chinese copy of the Bl-Touch an auto bedleveling touch sensor for a 3D printer.
After re-configurating a new version of the firmware for our setup in the Arduino IDE we went on with uploading the sketch to the Arduino Mega that was controling our 3D printer.
The problems
Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260.
Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a stupid mistake)
After we restarted the IDE and tried again we recieved the following error during the upload.
avrdude stk500_getsync() timeout communicating with programmer
After some Googling we tried the following fixes:
Remove all the !!! in the source code, Because of this the Mega
can enter some kind of safe mode
Tried a test sketch, Same error
When uploading a sketch presing the reset button on the board.
Sometimes the PC could also not detect that the board was connected it
would not show up in the Device Manager. But when we re-connected the
USB it would pop-up in the Windows Device Manager,
We might think we corrupted the bootloader of the Arduino Mega because we unplugged the USB cable during flashing. Prehaps someone knows somehting else that might be wrong with our setup.
Equipment used
Lenovo Y50-70 running Windows 10 with the Arduino IDE
Arduino Mega 2260 that was provided with the 3D-printer
USB cable for connection between PC and Arduino

I am currently trying to play around with developing on a BBC microbit on c++ through the Platformio IDE on Atom.
I have got the software working with other boards (various NUCLEO boards that I own), and the code itself for the mircobit is the simple "Hello World" scroller that compiles fine on the mbed online compiler.
When compiling on platformio I get:
Attribute Error: 'PlatformIOLibBuilder' object has no attribute 'get_inc_dirs'
I have tried installing the microbit University of Lancaster libraries, and platformio says they are installed but it doesn't appear in the lib folder of the project I am using.
When it comes to developing I am very much a newbie in terms of setting up environments and IDEs, and I keep searching everywhere for answers on this but its hard to filter out what I need to do to fix this issue. While the microbit is a supported board, there is no guide as to how to get started with it, and every other board just seems to work fine with all the default installations.
UPDATE: The solution below works also for Ubuntu and windows though LED displays come out a bit garbled when you try and scroll text. However, serial communication shows that the actual microbit is doing what it should.
The errors in the display may be down to the fact that the microbit libraries are v2.0.0-rc4 whereas the most up to date version of the University of Lancaster Libraries appear to be v2.0.0-rc10.
Edit:
I am using Linux Mint and the platformio plugin in Atom. I had the reported error. First of all I used the command line tool to update platoformio:
~/.platformio/penv/bin/pio update
To remove the get_dirs error and enable my code to compile:
In
~/.platformio/lib/nrf51-sdk/platformio_extra.py
change line:
pio_lib_builder.env.Prepend(CPPPATH=pio_lib_builder.get_inc_dirs())
to:
pio_lib_builder.env.Prepend(CPPPATH=pio_lib_builder.get_include_dirs())
I got this idea from:
https://github.com/palfrey/nrf51-sdk/pull/1/files
To get my compiled code to load I run atom as sudo:
sudo atom
I tried to build ios version of my ionic application which I build using Visual Studio 2017, but it seems it never can "install" to the simulator. The simulator is launched on the mac computer, but the application is not running, even I cannot find the icon in the simulator.
I suspect that it because the wrong naming of the target device.
I notice there is /cordova/build/.../emulate?target=iPhone+5 404 line on the mac's terminal, while when I try to the list the available target, it should be target=iPhone-5.
I'm a newbie in ionic and I don't know if it is the cause of problem that make the application is not shown at the emulator.
If it is not the problem, is there anybody can help me to find out what is the cause so the application cannot be debugged (not shown in the emulator)?
If it is the cause of the problem, then how can I change the command send from visual studio to the mac computer?
Thanks in advance for the help.
I see the following error whenever I try to debug "Cross Platform" under "C++" category: "Unable to start debugging. Unexpected GDB output from command "-target-select remote :5039". Remote connection closed"
I've installed all of the contents when I downloaded Visual Studio 2015 community and I ran it on Windows 10 Pro which supports Hyper-V.
I've been searching a solution for this and I've found an assumption:
"What is your debug target, the VS Android Emulator? When we saw this before it turned out to be a bad emulator image. Do you have this problem with all targets (e.g. if you try a physical device) or just one?"
In my case, I just tried this via Emulator(VS Emulator 5" Lolipop (5.0) XXHDP Phone (0x86 -...)
So I've sent an Email to VS 2015.
And the answer was like this:
"Sorry for the delay in responding we were looking at an emulator image of another user that ran into this problem so I was waiting until we had the results of that investigation to report back. We actually were not able to find anything wrong the emulator itself, our current hypothesis is that it is a network or adb problem interfering with GDB’s ability to connect to GDB server on the remote machine. Do you see this error every time you try to debug, or if you reboot the emulator will it work sometimes right after the reboot? Next time you see the error, can you open the emulator’s console mode by going go the Hyper-V manager and double clicking the emulator. Then find the location your app installed to and run “gdbserver --version" from the app path and let me know what it says? This will validate if the correct version of gdbserver is on the device."
So we are trying to solve this problem but I'm also asking here just in case.
Is there anyone who has magical solution for this problem?
I'll put a comment on this if I figure out how to solve this.
Thanks in advance.
** Following answer is from the manager of Visual Studio 2015:
You are only the second person who has run into this issue, and the first person that ran into it provided their everything works correctly when we run their .vhd on our machines so it appears to be some strange problem where gdbserver (which comes from the Android NDK provided by Google) crashes only when running on certain machines. Unfortunately the .vhd you provided does not appear to be the correct one it won’t boot for me. You can see the .vhd file being used by the emulator if you look under the settings of the emulator in your Hyper-V manager. .However given we got the other person’s .vhd you can hold off providing any additional information at this point. I’m waiting to hear back from the emulator team on if they have any ideas since this appears to be an issue only on specific machines since.
If you don’t mind my asking, if you don’t have a background in computers what inspired you to try C++ on Android? That scenario will be significantly more complicated than doing Java on Android.
It's been almost two months since I got this answer but I haven't got any additional response from them yet. So, I ended up quitting developing an application by using VS2015.
If you run into this problem, there are only two ways to go. Change your computer or stop developing application via VS2015.
If the project name contains spaces, the whole remote debugging fails. Visual Studio also creates weird paths. When checking out the "Blink1 for Raspberry Pi" template, I named the Project "Blink1 for Pi", which resulted in a path like this:
~/projects/Blink1?/for/pi/PI/for/pi....
And all the debugging failed. When I recreated this keeping the project name "Blink1", everything worked fine. It's a pity, that spaces aren't handled here...
I am using Genymotion emulator to run my calabash android tests. I have around 7 feature files and after successfully running 3-4 features geny motion crashes with the following exception:
"Player.exe has stopped working"
"Microsoft Visual c++ runtime Library
The application has requested the runtime to terminate it in an unusual way"
Unfortunately I am not able to post the images for this post.
Has anybody got a fix for this?
Thanks in advance!
