Arduino Uno and Arduino release 1.8.1

Hi,
I have Arduino 1.6.0 and 1.8.1 software installed on my PC running W10.
Version 1.6.0 has been installed for about 12 months and works fine when I compile and download the BLINK programe to the Uno.
I obtain errors when I compile and download the BLINK programe to the UNO using software version 1.8.1, refer to the attached file.
Any assistance with this problem would be greatly appreciated.
Regards
Rob

When you want to post an error to the forum do it right in the post, using code tags (</> button on the toolbar), instead of as an attachment. By using a .doc attachment you make it much less likely you will get help with your problem.

That said, I did download and open you attachment and here’s what I recommend you to try:

  • Tools > Board > Boards Manager
  • Wait for downloads to complete
  • Click on Arduino AVR Boards
  • Click “Update”
  • Wait for installation to complete
  • Click “Close”

Thanks for the advice. I did as you suggested below. I notice I have Arduino AVR boards version 1.6.17 installed and there is no further option to update unless I choose an older version such as 1.6.16 or less. I did not try to update to an older version this as I thought that would not work. Version 1.6.17 appears to be the latest version. I also assume having two versions of the Arduino programming software (1.6.0 and 1.8.1) on the same PC is not an issue?

Below is a link to my dropbox of the screen shot capture of the Arduino AVR boards screen. This is the first time I have tried to use drop box as a link, I hope this works for you.

There seems to be something strange going on here, you have Arduino AVR Boards 1.6.17 installed but there must be an old copy installed somewhere that Arduino is using instead. Please do this:

  • File > Preferences > Show verbose output during: > compilation (check) > OK
  • Sketch > Compile/Verify
  • After the compilation fails you will see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the errors here using code tags. If it's longer than the forum will allow then attach it as a .txt file.

RobCb: I also assume having two versions of the Arduino programming software (1.6.0 and 1.8.1) on the same PC is not an issue?

It's certainly possible to have both. I have both installed on my computer without any problems. It is possible it's the cause of the problem but I don't think uninstalling 1.6.0 would solve it.

Using dropbox for the screenshots has similar issues to attaching a .doc file. Some forum users will just skip over your post when they see that, those might be the same people who could have helped you if you made it easier for them to do so. When you need to post images you should attach and embed them following these instructions: http://forum.arduino.cc/index.php?topic=364156.0 that will get the most eyes on your issue.

When you post links please use the chain links icon on the toolbar to make them clickable. Otherwise we have to copy and paste the URL, not so hard but you want to make it as easy as possible for us.

Hi,
Thanks again.
I have tried what you suggested: File > Preferences > Show verbose output during: > compilation (check) > OK.

After compiling I do not obtain an orange bar with the “copy error message” button.
After trying to UPLOAD the BLINK sketch to the UNO I then obtain the orange bar with the “copy error message” button.
The error message is attached.

I think I figured out the problem with the old Arduino AVR Boards version being used from looking at the error output. What do you have File > Preferences > Sketchbook Location set to?

Hi, I think your on the money, the sketch book location is C:\Arduino\arduino-1.6.0. This is the location for my version of Arduino 1.6.0.

In trying to find a similar sketch book file in my location of Arduino 1.8.0, I could not find one. I am not sure what to set the sketch book location to?

You can set it to anything you like except for the Arduino IDE installation folders. Just pick something convenient. It usually defaults to the My Documents folder on Windows but I never use that folder so I have mine somewhere else. It's possible you have saved sketches or installed libraries to C:\Arduino\arduino-1.6.0 while you had that folder set as you sketchbook. If so you may need to copy those folders to your new sketchbook location.

After changing the sketchbook location try uploading again, hopefully that will fix the problem. If not then please post the error messages you get after the failed upload with verbose output during upload turned on in your preferences.

Thanks you so much for your assistance, that worked fine. Regards Rob
