Rick.

You may have noticed I've been MIA for the last month.

I'm back at home now, but not fully up to speed with things yet.

I'll move that post to General

BTW. I posted a separate thread about that Hackaday article

Congratulation! :D

Yes, the poster of the project credits its source, and has added some value to it, so I have no objections.

Yet another STM32F103 based DSO (probably a clone)

Youtuber 12VoltVids did a build and review of that





He has some other good repair and test videos.

But isn't the code from GFX better for this purpose? It's already functional right?
GFXscope version v2.0 (F303 based) is not free. Well, for me it is, cause I bought "rights" to v3.0 firmware, and v2 comes as a bonus, if needed. But it is impossible to "borrow" to someone (even if I would want to), they are particular chip locked. But, yes - if you have bought v2.0 firmware, then such "BluePill Pro" makes easier to experiment.
Free F303 based is FusionScope ("Murzik"), also on radiokot.ru (it translates as "radio-cat", btw. All electronics hobbyists apparently are cat-persons for some reason. I know I am). It would be easy to make "Murzik" with "BluePill Pro". Link:

I both cases above, there are no sources, just binaries. "O-Scope" community here is interesting with its open nature and ever-changing :)
Revisiting this entry...
Seems to be interesting as he uses an F303x8 variant that only has 2 ADC's, so about 16MSPS@8bit. I have the F303xD variant that has 4 ADC's, so in theory could go up to around 30MSPS@8bit (20MSPS@12bit).
Still have to check if it's possible to interleave the 4 ADC's...

Is there support for F303'duino?


P.S. @ahull thanks for the links. I haven't seen these. The title doesn't have the whole "DSO150" string :)

Use STMs Core or STM32GENERIC
