Trinket keyboard tutorial

[jackv]

When i tried to compile the program I get the following warning:

In file included from /root/sketchbook/libraries/TrinketKeyboard/usbdrvasm_includer.S:24:
/root/sketchbook/libraries/TrinketKeyboard/usbdrv/usbdrvasm.S:17:1: warning: "__SFR_OFFSET" redefined

I am using Ubuntu 13.04 64 bit.

Thank you

You are trying to compile as root, you probably don't have the libraries installed in the root's location.

You might find it easier to go ahead and set up your environment to be able to run the arduino ide as your regular user.

I've explained how to communicate with the Trinket as the regular user several posts such as this one:

It will involve setting up a custom udev rule.

It isn't usually good to run GUI programs as root, as you can see you get problems such as this one, and even worse.

They are just warnings, and these particular warnings are safe to ignore.

I haven't figured out how to get rid of them yet, and it's not a high priority to fix.

[jackv]

The libraries are in /root/sketchbook/libraries, see first line of the message.

The program doesn't run.

[schnee72]

I'll stand by the idea that you'll have better luck not running arduino as root.

[frank26080115]

The program doesn't run.

Did it enumerate? Can you get some lsusb output?

[jackv]

No, no sign of any output.

Sorry It took so long to get back to you.

twolf - I applied the udev rule so I don't have to be root. It still doesn't work.
