KC60 SE

========================

See build environment setup and make instructions for more information.

After setting up the QMK build environment, assuming qmk is in qmk_firmware:

  • cd qmk_firmware/keyboards
  • mkdir kc60se
  • cd kc60se
  • git clone [email protected]:BlakeCLewis/kc60se.git .
  • or git clone https://github.com/BlakeCLewis/kc60se.git .
  • cd ../../
  • make kc60se:default
  • or make kc60se:hhkb_qwerty_fbr

Description:

  • 60% keyboard PCB;
  • clone of GH60 with minor differences;
  • supports ANSI, ISO, HHKB, and/or WKL layouts.

Technical specifications

Column pin configuration:

  • col 0-13
  • pin: F0 F1 E6 C7 C6 B6 D4 B1 B7 B5 B4 D7 D6 B3

Row pin configuration:

  • row 0-4
  • pin: D0 D1 D2 D3 D5

LED pins (found these with Ohm meter):

  • B2 Capslock LED
  • F5 Backlight LEDs

Unused pins (I can't find anthing connected to these pins):

  • B0 F4 F6 F7 E2

DIP switches enable/disable keys K41 and K4C the second keys from the ends on the bottom row:

  • When there are three keys on each side of the space bar, the middle of each 3 (K41,K4C) are WIN/GUI keys that will pause games, these switches allows you to disable WIN/GUI during games;
  • default layout is "Win Key Less" (WKL), K41/K4C are LALT/RALT, so I have both dip switches in the ON position;
 dip      keys
#1 #2   K41   K4C
 1  1    1     1    both keys enabled
 1  0    0     1   
 0  1    1     0
 0  0    0     0    both keys disabled

6 pin header next to the Atmega32u4:

:::

2 4 6
: : :
1 3 5

1 - B3    (square pad, column 13)
2 - VCC
3 - B1    (column 7)
4 - B2    (backlight)
5 - Reset
6 - Ground

Enter the Bootloader:

  • unplug keyboard
  • while holding down 'Space' & 'B', plug in USB cable and continue to hold for 8 seconds;
  • 'lsusb' should report something like '03eb:2ff4 Atmel Corp. atmega32u4 DFU bootloader' instead of 'feed 6060';
  • LEDs should be off, and keyboard does not work;
  • if for some reason that doesn't work, (CAREFUL) while keyboard is plugged in, momentary jump pads 5 & 6 to enter bootloader;
  • I found that flashing the firmware through a USB hub did not work consistantly. Most of the time it would finish with errors, but keyboard may partially work. If plugged into the computer it flashes with no errors.
