 A modular framework for data logging and remote data acquisition.

+The name represents a seed found in a plum fruit - the "core" of the plum.
 Although not used in this manner it sounds sufficiently good to be used
 as a name for a totally unrelated project.
 
+plumCore is a C framework using the microkernel/services pattern. FreeRTOS
+scheduler is used as the microkernel providing task scheduling and a basic IPC.
+All the rest is implemented as modular services. A plumCore service provides
+interfaces used by other services. Interface dependencies are either discovered
+in runtime (service locator pattern) or injected (dependency injection). Even
+the service locator is implemented as a service. Most of the code looks like
+and behaves in an OOP manner. As an user interface, a tree-structured CLI
+(command line interface) is available to configure the device.
 
+plumCore use cases are various remotely operated measurement/DAQ systems with
+optional on-site data processing (edge computing). IoT and consumer hardware
+are not plumCore's target applications.
