Aplikasi Counter Bank GUI

Teman-teman sy ingin berbagi tentang penerapan raspberry untuk aplikasi counter di RS, Bank dll
cara kerjanya adalah: sistem raspberry menerima data serial dari PC operator
msial operator2 mengirimkand data antrian U77

maka secara background : PC tsb akan mengirimkan data serialnya ke raspberry
dan raspberry akan meresponnya dengan menampilkannya secara Realtime ke display moitornya
Sederhana namun bobot dari koding ini adalah sbb:
+Realtime GUI
+Realtime Serial Event
+Python Berbasis GUI

Harapannya semoga aplikasi ini bisa menambah kecintaan kita pada raspberry PI....CMIIw :-)
