Subscribe to Atmel SAM3U-EK eval software notification Included software components:
Eval package:
The eval packages have been designed to provide customers and potential customers with a complete, easy to use software package for the specified target hardware and target compiler. They allow to easily check out the target hardware, the target compiler and our software components. This evaluation process typically does not take a lot of time since the software can be easily recompiled and downloaded to the target.
Some packages are executable demos, which can not be modified; some packages are trial versions, which come with the software in a library and the application in source code form, as well as a project for the IDE that has been used. Trial versions can usually be recompiled easily in less than a minute if the required compiler and IDE is installed. The application program can be modified, allowing intensive testing the hard- and software for fitnes. emWin trial versions usually also contain a simulation environment which allows test and recompilation on a PC.
USB examples:
| The eval package includes USB bulk samples for simple data transfer between target and PC as well as device class samples, such as MSD, HID and CDC. |
