+Here are some general principals you should try to adhere to:
+* Keep it simple. Please, don't think like a high-level lang programmer. Think embedded, and keep code concise, without any unecessary layers.
+* No dynamic memory allocation, except during setup/begin functions.
+* Use the same brace and indenting style that's in the core source modules. (A .clang-format is prob going to be added soon, but please do NOT retroactively re-format existing code. This just creates unnecessary diffs that make finding problems harder)
