1 PC88(Late type) to USB keyboard protocol converter
2 =======================================
3 Target MCU is ATMega32u2 but other USB capable AVR will also work.
8 This converter is for TYPE-B keyboard. For keyboards other than TYPE-B,
9 change the mode switch on the back of the keyboard.
11 Stand the left foot on the back of the keyboard and there are two slits.
12 There is a mode change switch in the back of it.
14 When this switch is up, TYPE-B mode is set.
16 When connecting a keyboard to this adapter, be sure to set to TYPE-B mode.
34 Wiring: You can change this with editing config.h.
37 ----------------------------------
49 Signal: Asynchronous, Positive logic, 20800bps, Least bit first
50 Frame format: 1-Start bit(Lo), 8-Data bits, non-Parity, 1-Stop bit
56 Just use 'make' to bild firmware for TMK PC88 converter.
58 $ make -f Makefile.unimap clean
59 $ make -f Makefile.unimap
63 $ make -f Makefile.unimap dfu
65 then push button on converter to flash firmware.
67 If you are using ATMega32u4 based board instead of premade TMK PC88 converter(ATMega32u2) use following commands.
69 $ make -f Makefile.unimap.32u4 clean
70 $ make -f Makefile.unimap.32u4
71 $ make -f Makefile.unimap.32u4 dfu
