ATMEL Firmware for Sensor Communication

I am in need of a firmware engineer with a strong skills in developing code for ATMEL SAMG processors. The focus of the project is to develop firmware that runs in our 5GV POD modules that interfaces with "plug in modules" that communicate with external sensors. We also require a firmware module that runs on the existing 5GV/Razor/Mini product and interfaces with the POD module(s). Key functions include: - Constructing firmware for the POD module to interface with plug-in modules that in turn, interface with external sensors like vibrating wire sensors, RS485 sensors, 4-20ma sensors, SDI-12 sensors, Pulse and Voltage Input sources. - Developing a module for the 5GV/Razor/Mini gateway/logger that drives one or more PODs. This includes configuration, interrogation and data capture data from the POD. - Test and debug the code on production 5GV/Razor/Mini and one or more PODs (initially, VW and RS485) - Collaborating on comprehensive test plans to verify the firmware's functionality and reliability. I am looking for freelancers who have adept skills and experience in firmware development, specifically familiarity with the aforementioned sensor types and data logging systems. Additional specifications, requirements and test devices will be made available to successful applicant(s). Our 5GV/Razor and Mini use common firmware and SAMG55J19 processor; the POD also uses a SAMG55J19 processor and base firmware is available to kicksart the development. Mastery in working with IAR Workbench and ARM processors is crucial to this project. Having working experience with line protocols like RS485, 4-20ma, SDI-12 would be an advantage.
