Numerous trade spaces compatible with existing system capabilities are explored and possible solutions discussed before a final answer is determined. An Embedded Developer then begins decomposing the individual specifications to the necessary hardware instructions and desired system configurations. The coding effort starts with special attention given to unique system parameters critical to ensuring the radar is controlled within strict operating parameters, operates correctly and provides the expected data for collection. The testing aspect of the development effort includes initial measurements of the generated command signals using various test equipment and subsequent follow-on verification of a myriad of system parameters that could cause system or subsystem faults resulting in damage to the radar. The waveform is then put through a series of system level tests to verify the waveform provides exact control timing and data collection instructions to all radars in the system. Data is collected and analyzed using locally developed tools to verify the radar systems are operating correctly, individually and collectively, and producing the intended results. Test Equipment, Hardware and Software used: Oscilloscope, Spectrum Analyzer, Single Board Computer (SBC), VxWorks OS, Local software created on Visual Studio (C#). In an analogous position, the Embedded Software Developer would create code commanding sensors and collecting sensor data for later analysis. Remoting a Digital Quadrature Detector (DQD) - The DQD consists of a Single Board Computer (SBC) and a sampling card used to sample radar data at very high rates which is then sorted and collected for processing. The DQD currently resides in a VME chassis shared with other hardware and this effort removed the DQD from the VME chassis while providing the same capabilities. The primary task moved messaging traffic between the chassis and the DQD into Ethernet to allow the DQD to be remoted and not reliant upon the VME chassis and hardware contained therein. After discussing the task with teammates and stakeholders the Embedded Developer created a set of requirements which specified, and added enhanced capabilities to, the data flow and messaging required to meet overall system specifications. The development created new messages and data injection into the framework to allow remote DQD operation. Continuous integration and testing was performed to ensure incremental success during development. Test Equipment, Hardware and Software used: Oscilloscope, Spectrum Analyzer, Wireshark, Single Board Computer (SBC), VxWorks OS, Local software created on Visual Studio (C#). In an analogous position, the Embedded Software Developer would take an existing device and remote it within a system to perform the original functionality without influencing the overall system's operation. Control of an IR camera - This task required an IR camera is to be installed on a system. Most of these cameras usually have proprietary commands and controls which need to be presented to users for proper operation of the camera. After discussing the IR camera needs of the group with teammates and stakeholders, the Embedded Developer created a set of requirements which specified the necessary functions to control the camera. The Developer used this knowledge to conduct market research to find a suitable host device and determine an appropriate software framework. A Panel PC with Windows IoT OS was selected to host the applications controlling the camera and Visual Studio (C#) and .NET selected as the software framework. The development started with reading vendor information to understand the commands and controls of the cameras and then bench testing with emulators to verify correct understanding of the instruction set. Software development required defining numerous threads and the software architecture to support the low level control requirements . click apply for full job details
