Teensy 2.0 #296

Open huggre opened 3 years ago

huggre commented 3 years ago

Hi, why is the Teensy 2.0 not supported?

tttapa commented 3 years ago

I don't own a Teensy 2.0, so I can't test it, but it seems to compile without errors for me.

Are you getting a compilation error? A runtime error? Does it simply not send any MIDI?

huggre commented 3 years ago

Thanks for your reply. Reason I asked was that it was not listed under supported devices. Tried anyway and got the following compile error:

C:\Users\hgreg\Documents\Arduino\libraries\Control-Surface-1.1.1\src\MIDI_Interfaces\Teensy-USB-MIDI-name.c:7:10: fatal error: usb_names.h: No such file or directory

include "usb_names.h"

Multiple libraries were found for "Control_Surface.h" ^~~~~ Used: C:\Users\hgreg\Documents\Arduino\libraries\Control-Surface-1.1.1 compilation terminated. Not used: C:\Users\hgreg\Documents\Arduino\libraries\Control-Surface-master Error compiling for board Teensy 2.0.

Have been testing the Teensy 2.0 with other MIDI libraries today without any issues.

You seem to be using an old version. Try at least version 1.2.0 or master. Version 1.1.1 didn't support the Teensy 2.0.

tttapa commented 3 years ago

The usb_names.h: No such file or directory error was fixed in back in May: https://github.com/tttapa/Control-Surface/commit/3f640698fd4675a4d4fdd75d1003c8e0a387360c

Works after deleting old version of the library. Looking forward to learning more about this library :-)

Note! You should consider adding the Teensy 2.0 to the list of supported boards.

tttapa commented 3 years ago

Glad to hear :-)

Could you let me know if things like MIDI over USB actually work? Teensy 2.0 uses a different MIDI USB implementation than the Teensy 3.x boards, and I haven't been able to test that yet. There could be problems with flushing the MIDI data, for example, which could cause high latency.

huggre commented 3 years ago

Hi, looks like the MIDI over USB is working based on some very simple tests i did. There is some latency but i'm not sure what to expect. Will give you you an update as soon as I have more to report.

By the way.., I'm not able to get the "NoteButtonMatrix" function to work. I know the hardware is working correctly but no note on/off events are created when testing your example. Could you please verify that it is working correctly from your side and let me know what i might be missing.

Thanks for your support

You could try to add usbMIDI.send_now() to your main loop, I'm not sure how long the T2.0 buffers the data before actually sending it.

I've just tried the NoteButtonMatrix.ino example, and it works fine on my Arduino Leonardo (same chip as the T2.0) using Control Surface v1.2.0.

You can easily verify that it works by connecting a wire between a row pin and a column pin. E.g. if you connect pin 2 to pin 8, the example should send note 3, connect pin 5 to pin 8 and it'll send note 10, and so on.

Just had to switch the rows and column definition and now the matrix works, thanks
