The Prosthetic Device Communication Protocol is a CAN-based protocol developed specifically for use within prosthetic devices, for connecting the components of the device, most importantly sensors and actuators. The lower levels of this protocol have already been developed. This thesis focuses on developing a device profile layer, to bring plug-and-play functionality to the protocol. Specifically, this thesis contains a proposed device profile layer, a description of an implementation of the profile layer, and testing of this implementation. Testing results were largely successful, most of the desired functionality was achieved in the implementation.
