Finish Linux application in GTK and write C++ libary for Mifare

We currently have a solution for golf course ball dispensers based on mifare. The solution is currently working on windows embedded. We are now working on a port to Linux ARM (Raspberry). Most functionality is already finished. Working items are: - Switching via GPIO - Realtime clock via GPIO is working - GTK interface is fully working - Touchscreen is working Items we still need to resolve: - We need to create a libary that GTK can call which to processes the mifare transactions. We use the omnikey 5427CK reader/writer. Methods we need are: Change credit, Read credit, Read data block (return ascii), Read card ID - We need logic that contacts the database (Microsoft SQL via ODBC) and downloads the price configuration - We need to determine the pricing based on the time and day. - We need logic where transactions are logged locally when the SQL is not available, and logging them to SQL directly when available. - Fix an issue where GPIO ports are all triggered when initializing the GPIO. (causing a the feeding of balls upon rebooting).
