`#define TERMINAL_HELP` enables some other output helpers that aren't really needed with this page.
|
||||
|
||||
Pressing "up" and "down" will allow you to cycle through the past 5 commands entered.
|
||||
|
||||
## Future Ideas
|
||||
|
||||
* Keyboard/user-extensible commands
|
||||
* Smaller footprint
|
||||
* Arrow key support
|
||||
* Command history
|
||||
* Command history - Done
|
||||
* SD card support
|
||||
* LCD support for buffer display
|
||||
* Keycode -> name string LUT
