Visual Micro Still Rocks
/I bought Visual Micro a while back. Not that I really needed to. The free version is actually plenty powerful enough for day-to-day use. It was just that I thought the product was so good that I really should support it.
For a registration you get a key that works on three machines. I've been through a few machines over the years (as you do) and last week I found that my key didn't work for my desktop. I emailed them, they cleared the key and I'm back in business again. Thanks folks.
If you are in any way serious about embedded development you should get this tool. The free Arduino SDK is OK for a while, but you'll fairly quickly hit limitations that will grate, and with Visual Micro you get all the lovely intellisense support and general niceness that comes with developing code in Visual Studio.
Visual Micro now works with all the esp devices and pretty much anything Arduino shaped as well. It's got some very interesting debugging support too, but I tend to rely on code instrumentation (print statements) when I'm writing embedded code, so I don't use it very much. Go get it.
