2.2.4 CC1352 Software Design

The collector and sensor software used in this TI design is a modified version of the collector and sensor example code provided with the TI 15.4 Stack. The TI 15.4 Stack and example codes run as state machines waiting for events. To make these example codes work, two modifications were necessary: A new event was added to the collector and sensor examples and added an additional task running in parallel in charge of triggering said event. The new event is triggered when new mmWave data is received from the mmWave. The following section provides is a description of the event and task.
