Hi guys,

after looking for a more advance Arduino IDE, i found your product. It was easy to install, which is a big plus compared to some other solutions.

Unfortunately, i experienced some issues. To be exaxt i try to develop programs for the Teensy 3.1 Board.

First of all, there is no code completition for me. In Options => Text Editor => All Languages, everythings activated.
If i choose for Example "Arduino 1.6 and Arduino Due", i get code suggestions using Ctrl+Space.

Choosing Teensy again, Ctrl+Space does nothing.

Seconds issue is... after Updating from Teensyduino for Arduino 1.6.X Beta 7 to Arduino 1.6.X Beta 10, i got the following error trying to compile :

[code]
Compiling 'MPU6050_tests' for 'Teensy 3.1'
arm-none-eabi-gcc*:error: {build.flags.ldspecs}: No such file or directory
Error creating .elf
[/code]

Sadly, installing beta 7 again, does not fix the issue...


Can you guys please give me some hints for a trip-proof start into using Visiual Micro ?

Thanks in advance,

Christian

I must admit I don't know what is the right way to fix this issue. However, here is what works fine for me:

1. Open the Arduino\hardware\teensy\avr\platform.txt file.
   
2. Edit the following section:
   
   Code (]## Link
   recipe.c.combine.pattern="{compiler.path}{build.toolchain}{build.command.gcc}" {build.flags.optimize} {build.flags.ld} {build.flags.ldspecs} {build.flags.cpu} -o "{build.path}/{build.project_name}.elf" {object_files} "{build.path}/{archive_file}" "-L{build.path}" {build.flags.libs}[/code):
   

   to: [code]## Link ## recipe.c.combine.pattern="{compiler.path}{build.toolchain}{build.command.gcc}" {build.flags.optimize} {build.flags.ld} {build.flags.ldspecs} {build.flags.cpu} -o "{build.path}/{build.project_name}.elf" {object_files} "{build.path}/{archive_file}" "-L{build.path}" {build.flags.libs} recipe.c.combine.pattern="{compiler.path}{build.toolchain}{build.command.gcc}" {build.flags.optimize} {build.flags.ld} --specs=nano.specs {build.flags.cpu} -o "{build.path}/{build.project_name}.elf" {object_files} "{build.path}/{archive_file}" "-L{build.path}" {build.flags.libs}

   
   
3. Restart Visual Studio.
   

The linker should work fine again.

There is a bug in the Visual Micro plugin that does not handle the boards.txt file correctly regarding the {build.flags.ldspecs} macro. However, I have no idea of how to fix it the right way. :-[

I've reported this buggy behavior in another forum.

ADMIN: It's not buggy just a new teensy feature that visual micro needs to now support. It's always best to avoid beta and immediate new releases of Ide's because it's impossible to expect Visual Micro to know of these changes before they are released.

Please follow the documentation and release notes which do not yet support teensy beta

If you use beta you have to take more interest and care. The teensy beta changed daily over last few weeks so unfair for anyone to think it will magically work with every visual micro version.

Don't use beta unless you know what you are doing and want to help not hinder

Or send us a crystal ball :D

Thank you for your quick answer. ;)

FYI - It is no longer beta, it was Teensyduino 1.21 was released 5 days ago.

I am new to trying to use Visual Micro for this, but like what I see.  Look foreword to having it fully work with the latest releases.  Thanks for your hard work on this!

Thanks. We will support is shortly  :)

Hi,

Please see current status in our release notes and also see the Teensy page for configuration instructions

http://www.visualmicro.com/page/Visual-Micro-Product-Version-History-Fixes-and-Additions.aspx
http://www.visualmicro.com/page/Teensy-for-Microsoft-Visual-Studio.aspx

Due to the fact that all Arduino 1.6.1 Teensy definitions are listed as AVR we will not be able to support it for a while. The above provides initial untested support for Teensy 121 with Arduino 1.0.x. Please follow the new releases section of the forum for future notifications about Teensy.

Thanks
