To use it, we need to implement the interface using a class and provide body to all the abstract methods int it. If we make an interface final we will not be able to implement its methods, which defies the very purpose of the interfaces. Therefore, we cannot make an interface final in...

It enables programming of the Hercules microcontroller through its CAN interface. The bootloader also helps designers update the user application code for products already deployed in the field. This document describes how to work with and customize the Hercules CAN bootloader application. The bootloader...
