ASCII to USB keyboard protocol converter
========================================
This converts serial console terminal into USB keyboard, tested with TRS-80 model 100 TELCOM application.
Target MCU is ATMega32u4 but other USB capable AVR will also work.
Hardware
--------
Connect RX, TX and GND to UART pin of AVR. Note that you may need line drvier/level shfiter like MAX232 to interface high voltage of RS-232C.
Build Firmware
--------------
Configure UART setting and Just use 'make'
$ cd ascii_usb
$ make
Then, load the binary to MCU with your favorite programmer.
Limitation
----------
- This cannot see key up event, you cannot hold a key.
- Alt, Gui(Win/Mac) modifier key are not available.
Scan code
---------
ASCII code(0x01-7F)
