This release makes the serial port chooser work better for users with lots of serial ports. It includes a binary version of the controller for MacOS.

The polargraph server firmware for PolargraphSD will now automatically run autorun.txt if it finds one on the SD card.

polargraphcontroller 2.4.2

  • Expanded the serial port listing window.
  • Added MacOS precompiled binary.

polargraph_firmware_polarshield 1.4

  • Added autorun feature. Upon boot, the machine will automatically run a file on the SD card called autorun.txt.

This release fixes a bug in the PolargraphSD firmware, and adds a couple of features to
the Polargraph Controller.

polargraphcontroller 2.4.0

polargraph_firmware_polarshield 1.3.1

  • Fixed: The pen lift height command was borked. Now unborked. Or at least,
    borked in a more functional way.

Firmwares can now compile in newest Arduino IDEs (v1.6.6+).
No more checksums!


  • Added: Adafruit_MotorShield to the packaged arduino-source/libraries.

polargraphcontroller 2.2.2

  • Added: The pixel density preview can now be posterized using a number
    spinner in the UI. This might be useful to visualise results when your
    dynamic range is compressed. Like when you're using a really small pixel,
    or a thick pen.
  • Added: The console is back! But different. This might be useful but is only
    intended as an interim solution. Ctrl-C for console.
    Partial solution to issue 8 (#8)
  • Fixed: The fix about motor defaults to be like PolargraphSD, mentioned in the
    previous version (2.1.1) actually has been fixed this time.
  • No MacOS build in this package. I've got no way of doing those on-demand.

polargraph_server_a1 1.2.1

  • Fixed: Compiles in Arduino IDE v1.6.6 and v1.6.7.

polargraph_server_polarshield 1.3

  • Updated: The comms protocol used in the polargraph_server_a1 has been brought
    over to polarshield. It uses proper line endings instead of checksums. In theory
    this is actually faster too, since it can
  • Fixed: Compiles in Arduino IDE v1.6.6 and v1.6.7.
