Teensy 2 outputs random data to Teensyduino Serial Monitor when "Hello World" is sent
Hello!
I'm using a Teensy 2.0 as a controller on a keyboard (Ergodox). My keyboard was not recognized by my computer so I wanted to see whether the actual serial communication works as expected.
I compiled and downloaded this program (which I took from one of your tutorials) to the Teensy:
As you can see, this should send "Hello World" to the computer every second.
What happens is that random data is sent ONCE to the computer. Here's an example of that data:
I have also tried to run other programs such as the "01. Simple > Blink"-program. That works as expected.
When activating the Halfkay bootloader the device is recognized by my computer (/var/log/kern.log):
I appreciate any help I can get!
Thank you
Edit: Here are some more information about my setup
Linux x86_64 (Debian jessie)
Arduino 1.0.5
Teensyduino 1.19
Teensy loader 1.19
I took some photos with my phone but they were too blurry, so tomorrow I will borrow a better camera and upload pictures of the soldering.
I added the phone photos until I get better ones, here is an album with the photos of the Teensy soldering top and bottom: http://imgur.com/a/O8y8k
