Introduction

All actions in this directory are in relation to controlling the vending machine hardware. As there are a lot of outside variables when working with hardware we have implemented the majority of error handling on our end. The machine will notify you and swap over to a default screen should a hardware error occur. The error screen will direct your technician to the source of the fault and guide them through the steps to rectify it. The only error handling you will need to implement in your app are stock related – for example, setting your items out of stock.

In all your vendOS apps you should give the user feedback for both the vending process and visual direction once vended to collect the product from the door below. This is less important in the VendMax+ as the user can see the elevator and vending process.
