Since its inefficient to write so much code, while making sure SetMethod and SetPrototypeMethod is called on each overload and track the namespaces used to store the callbacks manually, an experimental namespace_wrap and class_wrap were introduced, these two classes wrap the needed calls as well as track the targets (v8::Object). The wrappers do add overhead to function execution time but it didn't even register when I did performance analysis. to use the wrappers you'll need to...

A while back I've seen the DPS5015, which is a 50v 15A programmable power supply which has other versions, 30v/50v, 2A/3A/5A/12A and 15A, add on top of it the possibility to DIY your...
