     - Extension Board connector replaced by two SPI connectors.
     - Thermistor resistors 1K/4K7 instead of 4K7/4K7.

  1. USB tool: add a binary for OS X PPC.

    Traumflug committed Sep 24, 2014
    This was built on Mac OS X 10.4.11 with Xcode installed.
  2. Add USB tool.

    Traumflug committed Sep 24, 2014
    This is a tool to run MCP2200-based devices on Mac OS X prior to v10.7.

  1. SetupTest.ino: report received characters.

    Traumflug committed Aug 25, 2013
    This shall show incoming characters for debugging the serial line.
  2. Add all used footprints.

  1. Make SevenSwitch 1.2 release.

    Traumflug committed Aug 11, 2013
    New Features:
     - Pulldown resistor on the MOSFET gate for fewer chances to blow it.
     - Screw terminal footprint on the power supply side removed again,
       because it turned out these terminals fit into the holes for the
       disk power connector just fine.

  1. Make Gen7 Arduino IDE Support 2.1 release.

    Traumflug committed Jan 31, 2013
    New Features:
     - 16 MHz bootloaders actually work.
     - Rebased on Arduino 1.0.3.
  2. Rename SetupTest.pde to SetupTest.ino.

    Traumflug committed Jan 31, 2013
    That's Arduino IDE's new file suffix.

  1. Bootloader: fix it for 16 MHz ATmegas.

    Traumflug committed Jan 30, 2013
    Now, this was an unexpected one: the Gen7 Arduino IDE Support
    package's bootloader didn't work on 16 MHz chips and nobody
    told me! Finally, Simon Fitzback is my hero. He told me about
    the fault, I modified a Gen7 to 16 MHz found it myself. A really
    small change.
    The technical cause is, the single speed UART clock ist too inaccurate
    for 16 MHz. Double speed is better. On 20 MHz, both clocls are
    equally accurate, see ATmega's data sheet.

  1. Make SevenSwitch 1.1 release.

    Traumflug committed Jan 22, 2013
    New Features:
     - Better, bigger MOSFET (IRLB8743).
     - Option for a screw terminal power supply.
  2. Make Gen7Board-AVR 1.5 release.

    Traumflug committed Dec 20, 2012
     - The USB adapter is now on the main board. Pretty much what's
       on the ExtentionBoard-USB-B already, making this obsolete.
     - Noise cancelling coil for AVcc now 10 uH. This makes Gen7
       compatible with firmwares supporting LCD displays. Previously,
       hooking up a display would trigger the brown-out-detector often.
Commits on Dec 9, 2012
  1. Make ExtensionBoard-USB-B 1.0 release.

    Traumflug committed Dec 2, 2012
    New design. Features:
     - Establish USB connectivity using the Microchip MCP2200.
     - Plugs into the Extension Board header.
     - Makes the USB-TTL adapter obsolete.
  2. Make Gen7Board 1.4.1 release.

    Traumflug committed Dec 9, 2012
    New Features:
     - Distinction between extruder and bed circuitry.
     - Bigger MOSFET for the heated bed, making the heatsink obsolete.
  3. Make Gen7Board 1.4 release.

    Traumflug committed Apr 27, 2012
    New Features:
     - Added the extension header.
     - Moved motor heaters from KK156 to KK100 ones.
     - Reduced the number of endstops to 3.
     - Connect the thermistor to 5V Standby.
     - Better GND routing for even more accurate temperature readings.
     - Resistors between ATmega and MOSFETs now 10 Ohms.
  4. Make SevenSwitch 1.0 release.

    Traumflug committed May 3, 2012
    New Features:
     - It exists :-)
  5. Make Gen7 Arduino IDE Support 2.0 release.

    Traumflug committed Oct 28, 2011
    New Features:
     - Updated the Gen7 Arduino IDE Support package for Arduino 1.0.
  6. Make Release 1.3.1.

    Traumflug committed Aug 11, 2011
  7. Make Release 1.3.

  1. Bootloader: reconsider the page erase strategy and save 60 bytes.

    Traumflug committed Aug 12, 2011
    As avrdude always sends complete flash memory pages, there's no point
    in tracking distinct counters for pages to be erased vs. pages to be
  2. SetupTest: turn the other heater LED off while one is blinking.

    Traumflug committed Aug 12, 2011
    Formerly, the status of the second heater was undefined, which sometimes
    led to user confusion.

  1. Bootloader: remove support for lock bits.

    Traumflug committed Aug 11, 2011
    This is a somewhat questionable feature, as a programmer is required
    to clear these lock bits again.
  2. Bootloader: replace tabs with spaces, remove spaces at line endings.

    Traumflug committed Aug 11, 2011
    This is a purely cosmetical change.

  1. Make Release 1.3.

    Traumflug committed Jul 21, 2011
  2. tools: refine release making script a bit.

    Traumflug committed Jul 21, 2011
    Git apparently deletes emptied directories now, so we have to
    uncommit the old release first, then clean up the file system.
    Also, .zip and .png are ignored by git now, so we have to
    force-add them.

  1. Add a small setup test firmware.

    Traumflug committed Jul 7, 2011
    This is for use right after assembly, to make sure basic things work.
    Nothing fancy, but it compiles in the Arduino IDE.

  1. Board: fix a misaligned mounting hole.

    Traumflug committed Jun 29, 2011
    The misalignment was probably introduced unintentionally.

  1. Endstop: add a 'E' and 'D' sign to the TCST1103/2103 footprint.

    Traumflug committed Jun 25, 2011
    The previous one wasn't unambiguous and nobody told me for several
    months ... uäääh!

  1. Board: aligned Temp connectors with the surrounding connectors.

    Traumflug committed Jun 15, 2011
    Another cosmetics without functional change.
  2. Board: align CONN3 to CONN2.

    Traumflug committed Jun 15, 2011
    Also purely cosmetic.
You can’t perform that action at this time.
