Special Notes on using Pro Trinket with Linux

Pro Trinket is not supported on Linux operating system at this time - try Mac OS or Windows! However, you can try the

following - it does work for some computers

Linux is fairly picky about who can poke and prod at the USB port. You can always run avrdude or Arduino IDE as root,

which will make sure you have the proper permissions. If you want to be super-cool you can add a

udev

rule which will

let any user (who is not root) connect to the USBtiny driver. That way you don't have to be root all the time!

Check http://learn.adafruit.com/usbtinyisp/avrdude#for-linux for what to add to your udev file.

How to start the USB bootloader

Before you try to upload code to the Pro Trinket using the USB bootloader it must be in the Bootloader Mode. That

means its listening for a sketch or program to be sent to it

The Pro Trinket must be connected to a computer via a USB cable to enter bootloader mode. You can enter the

bootloader mode by pressing the little button on the board with your fingernail. The bootloader will 'time out' after 10

seconds, so to re-enter the bootloader mode just re-press the button!

Don't press-and-hold the reset button, be sure to press-and-release!

See the video below for what it looks like to plug it in, have the LED pulse in bootloader mode, time out and then press

reset to restart the bootloader

When the Pro Trinket is in bootloader mode, the red LED will be pulsing. Once the red LED stops pulsing,

you must press the reset button to re-enter bootloader mode
