The SystemView C module is a modified version of the embedded sources of Segger SystemView that has been adapted to work with the MICROEJ VEE.

This modified code needs to be added to your target VEE Port implementation. Once integrated correctly, MICROEJ VEE trace events can be visualised inside SystemView.

The notable change in versions v2.0.0 and v2.0.1 is the update the SystemView sources to the version 3.58.
