How to interface a (snack/drink) vending machine interface to a PC? Answered
Hello experts and entrhusiasts,
I don't know much about the currently used food/drink vending machines (Bianchi, SAECO, etc).
My question is the following:
-is it possible to interface/intercommunicate them with a PC ?
-what sort of connection do they have (RS232, CANbus,...) ?
-do they use a special language/operating system for managing the vending stuff ?
- are there available schematics, hardware/software descriptions about these machines ?
What I want to do is to query them about of the actual state of products(number of selled/not selled)
thank you your kindness
