hello dear teensy community,

i'm new to teensy and have no c or c++ skills unfortunately can't compile this source:

github.com

GitHub - nadavh/motorized_fader: USB MIDI controller with a motorized fader

USB MIDI controller with a motorized fader. Contribute to nadavh/motorized_fader development by creating an account on GitHub.
github.com github.com

could a kind soul make a fully compiled binary of this?

and help me with short instructions on what you need to pay attention to in order to compile successfully.

I need it for teensy 2.0

Thanks
 
Hello Paul,

many thanks for the quick response.

I was aware that teensy 2.0 is no longer up to date.

If I understood you correctly, it is no longer possible to compile for teensy 2.0 because support has been discontinued.

The only option would be to load an existing .hex binary into teensy 2.0 using the teensy loader.

Using newer teensy boards would be an option, but the developer from the source mentioned above has designed a specially suitable PCB mainboard for teensy 2.0.
Since the pin assignment of new teensy boards will be different, a new pcb board would have to be designed.
At this level of effort I would get out.
are my statements are correct?
 
Software for Teensy still supports compiling for Teensy 2.0. Anyone can see this in Arduino IDE with Teensyduino installed. Simply click Teensy 2.0 from the Tools > Board menu. Easy peasy!

Teensy 2.0 hardware is no longer being manufactured. The software is only usable with old Teensy 2.0 boards. No new hardware is being made.
 
I understand hardware-wise.

As I said, I always get error messages when compiling.
Would you be so kind to provide me the compiled version of itand explain the procedure?
 
No, I'm not going to do it for you. But if you show an exact copy of the error, I might help you do resolve the problem yourself.
 
sure no problem this is what i done. copy all codes from source to sketch folder.
After i copied the content of MotorizedFader.cpp to sketch
"put your main code here, to run repeatedly:"

then press compile and the first error come up see in picture.

Tried to compile the code and it finished OK...

Could the red circle below be the problem? A double declaration?

I just copied the raw MotorizedFader.cpp code into an empty sketch, added the 2 ButtonPanel files to the sketch, set USB Type to "MIDI" and compiled it.

great to hear it's possible.

i try the same as you describe but other errors comming up.
I must be doing something wrong.

could you send me the binary file?
 
hey paul it think it´s done could you check my code please?
