Pre-Built Txtzyme Hex Files

Txtzyme runs on Teensy and Teensy++ versions 1.0 and 2.0. These devices are available, inexpensive and well supported by http://pjrc.com/teensy. Once you are in possession of a device you will need to:

Choose the hex file that corresponds to your Teensy. The correspondences are as follows:

  • at90usb1286.hex for Teensy++ 2.0
  • at90usb162.hex for Teensy 1.0
  • at90usb646.hex for Teensy++ 1.0
  • atmega32u4.hex for Teensy 2.0

You can download the .elf file that corresponds to your Teensy. If you do, then the Teensy loader will check that you are actually programming the correct part as specified in the .elf file.

Once Txtzyme is running you can send commands to it from the shell. Here is how to send a "blink" program from an OS X Terminal window:

    $ echo '5{ 6d 1o 100m 0o 100m }' >/dev/cu.usbmodem12341

You can generate Txtzyme as you would any other text file. Here is how you can grab the text output from the morse project and run it:

    $ curl http://github.com/WardCunningham/Txtzyme/raw/master/projects/morse/morse.txt >/dev/cu.usbmodem12341

Expect this to blink out a familiar message in Morse code.
