This is worked!
This looks very good and very cheap to make. Such a shame our Chinese friends always restrict their content. you can't even signup using another country's phone number!
however, looking at just the screenshots of the PC software. it's a programmer-only version and does not have debugging features enabled. Yet it's very cheap (the PCB and components won't cost more than 3$) and nice to have.
I'm mainly interested in the .Net program. It'll help a lot in analyzing the programming sequence.

I have 2 programmers. they are the old series. the yellow one is for batch production and does not support debugging.
the black one (Link) is used for programming and debugging however it doesn't support batch programming for production.
both work with FMD and Origin IDE.
I do not have a logic analyzer, unfortunately. (the only missing tool in my arsenal!)
I've been in possession of both for about 2 years now and let me tell you one thing. even though the ICs are super cheap and well-suited for small applications, the support, documentation, and everything else is a headache!
if you encounter a problem, it's highly unlikely you'll find documentation or help other than what is already available. also, keep in mind that the silicon of the ICs have had several revisions in just 3 years to fix whatever they messed up in previous revisions. This means unreliable production.
I've tried contacting FMD via email or even suppliers to ask for support and never got a response back! they even don't publish the IDE on their website and you'll have to get it from suppliers manually! the compiler is XC8 in the heart but they rebranded it as GCC! These are a lot of red flags in engineering, however, because of the cheap price people still consider them.
