I am trying to program a Sparkfun pro-micro 3.3v arduino clone. I have the files installed and included the path to the folder containing pins_arduino.h in the toolchain compiler directories list.   

On compile I see a 'pop-up' message: 'error reading variants path' and the compiler output is:

====
Compiling 'promicrotest_04' for 'SparkFun Pro Micro1 8MHz/3.3V'
promicrotest_04.ino:In file included from
arduino.h:213:26: error: pins_ No such file or directory
promicrotest_04.ino:No such file or directory
Error compiling

=====

If I save and restart the path to pins_arduino.h is missing from the directories list. I am sure it is the right path.  (C:\Program Files (x86)\Arduino1p05\hardware\SF32u4_boards\variants\promicro) 

It all works OK with the Arduino IDE.

I am using Arduino 1.05 because I also want to use Teensy, which requires that version.

Thanks.

Hi Mike,

Gilles is right about installing the sparkfun hardware/toolchain in "arduinoIde\hardware\". 

Another optional location which is not dependent on ide revision is sketchbookfolder\hardware\ (normally documents\arduino\hardware)

I am not sure if that is the current board name. It's worth revisiting the sparkfun page and downloading the definition(s) for Arduino 1.0 which will be compatible with 1.0.5.

It is also an idea to clear the current sparkfun definitions (and tool chain files) you have installed for the board prior to copying new ones from sparkun.com

Great, thanks for the update and thanks to Gilles

Great.

Question. Have you used the Teensy app option in Visual Micro or Arduino 1.0.x?

Thanks

Hi mike,

Yes sorry I wasn't very clear. If you have set your Teensyduino Ide location in Visual Micro for the Teensy application then that answers the question thanks. 

I look forward to one day getting back to some projects, yours sound interesting.

The reason I ask is that one of the main differences between using the Arduino 1.0.x and the Teensy options in Visual Micro is to prevent this message.

Does this message appear for every Teensy project? Even the ones that use Uno or the sparkfun board?

Thanks

Mi Mike,

Yes I know thanks. One of the only differences between the Teensy option in Visual Micro and the Arduino 1.0.x is that we handle the "non-atmel" processor of Teensy 3x

I think that if you remove the folder location from Arduino 1.0.x and just use the Teensy option that error when you open a project will go away. However because you have the error I would open the project, select a normal board like the Uno then close and save the project. Then re-open and select the Teensy 3 using the "Teensy" application option in Visual Micro. Then save and close your project. When you next open the project I would not expect to see the error.
