TUI per la stampante per scontrini in HackLab
|
||||
|
||||
Presuppone che la stampante sia attaccata via seriale con un adattatore usb e accessibile da /dev/ttyUSB0
|
||||
|
||||
## Usage
|
||||
|
||||
Per compilare
|
||||
|
||||
``sh
|
||||
$ go build
|
||||
$ chmod +x ./Scontrini
|
||||
``
|
||||
|
||||
Per la TUI
|
||||
|
||||
``sh
|
||||
$ ./Scontrini
|
||||
``
|
||||
|
||||
Si può anche pipare da programmi esterni
|
