Alternative Controller for HHKB =============================== Feature ------- - Mouse Keys - NKRO on USB - Keymap Layers Customize Keymap ---------------- see keymap.c. Build for Teensy ---------------- 0. Edit matrix.c. adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts) 1. Define macros in config_pjrc.h.(Optional) VENDOR_ID, PRODUCT_ID and string descriptor. IS_COMMAND 2. Edit Makefile for MCU setting and build options. MCU, F_CPU MOUSEKEY_ENABLE, USB_EXTRA_ENABLE, USB_NKRO_ENABLE 3. Build hex file. $ make 4. Program MCU. $ make program Build for V-USB --------------- 0. Edit matrix.c and usbconfig.h. adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts) define macros for V-USB in usbconfig.h. 1. Define macros in config_vusb.h.(Optional) IS_COMMAND 2. Edit Makefile.vusb for MCU setting and build options. MCU, F_CPU MOUSEKEY_ENABLE, USB_EXTRA_ENABLE, USB_NKRO_ENABLE 3. Build hex file. $ make -f Makefile.vusb 4. Program MCU. $ make -f Makefile.vusb program Using a bootloader to program for convenience is recommended. Once program this V-USB bootloader at first, you can program MCU without extra programmer. You should have reset switch to start up as bootloader mode in this case.
