PROJECT COMPLETE
In general, the NimbleSig design has met my objectives. I found that Keil’s IDE and Luminary Micro’s EVM worked well together. Luminary Micro’s API library for its LM3S811 greatly simplified the writing of the firmware. I think it should be quite easy for others to pick up where I left off to customize the firmware to a specific application.
My only regret was my selection of a power regulator in a package that was difficult to solder without an oven. If there is sufficient interest demonstrated in NimbleSig, I may redesign the PCB artwork for power regulator chips in packages that are easier to work with.
I did my best to make the overall content of this article as factual as possible; however, there are no guarantees implied about anything presented here. Thus, anyone who uses my NimbleSig design or any portion of it must accept all of the associated risks.
