HoodLoader2 SerialKeyboard example
|
|
|
|
This sketch should demonstate how to program a basic sketch with HoodLoader2.
|
|
It was used to demonstrate that Serial and HID is working properly.
|
|
|
|
Open the Serial port, type in anything and see that Serial and Keyboard is working.
|
|
See official documentation for more infos.
|
|
|
|
Use the F() macro to save strings in PROGMEM to keep ram usage low.
