@ -4,10 +4,10 @@ SmartyKit Apple I replica drivers and software (http://www.smartykit.io/).
|
|||
All needed libraries included in repository in /Arduino/libraries
|
||||
|
||||
## Keyboard Driver
|
||||
Keyboard driver uses Arduino PS2Keyboard library.
|
||||
Keyboard driver uses Arduino PS2KeyAdvanced library.
|
||||
|
||||
## Video Driver
|
||||
Video driver uses Arduino TVout library.
|
||||
Video driver uses Arduino custom 2.8" TFT screen driver (based on Adafruit driver) and TV Terminal library.
|
||||
|
||||
## Software Emulator - POM 1
|
||||
POM 1 cross-platform emulator by Verhille Arnaud to test SmartyKit 1 ROM with software.
