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) |
