Hello Everyone. My how the forum has changed. Just dropping a recent odd experience here to see if anyone might have any comments. No. I don't use CubeMx and no this isn't another 3 year anniversary item regarding initializing the DMA before any peri...

Okay. Somehow I've stepped into another hole. Maybe this helps someone else avoid it and might shed light on it here - So the main question for me while trying to troubleshoot a POSSIBLE problem - which I always first blame ME - for is : What trigger...

Good to see some familiar fac... AVATARS still here!We have some products that use the mentioned ST micro. They were using the ST supplied virtual com port USB example code and drivers from back in the Cube 1.6 days. We've seen this occurrence in 2 d...

Hello ST folks. Recently, "THE MAN" updated us to Win10. Of course this broke a few (dozen) things.Oh yes . I know VB6. Unsupported thin ice. Just like they like it around here. The story is we have a load of small TEST applications wrote with this ...

Yes. Prototypes which many times turn into solutions for quick turn one off projects. And in THIS case - the "code generation" is done by ............... ME! ... :) Not CubeMX. "I" don't use CubeMX. Now of course - I'm tempted to try CubeMX with ...

Just droppped in to finalize. Thanks everyone for the feedback. And thanks Pavel A. for the kudo!This may serve as an example for the less experienced attendees who might get this far - of what you might run into if you rely on HAL for some quick fi...

Arg,,,, Probably 4-5-6 years since I was bit by that one. Okay - Say you need to use 2 SPI devices. And you want to use DMA on BOTH!You KNOW you need to init the DMA before any of the other peripheral stuff that uses it gets initialized.So "I" did ...

Hi JW!. Thanks for the time. "So, without DMA you see activity on SCK and MOSI, and with DMA you don't?"Yeeeessss.... EXACTLY! Raises an eyebrow right? :)I call BLOCKING SPI3 - it worksI call TXDMA SPI3 - it DOES NOT TXI call TXDMA SPI1 - it works...

Thank you Piranha. Yes the abstraction level created by all this "CLICK IT TO WRITE CODE" stuff gets users far removed from the real execution level stuff but that's a common talking point here. Always has been! :)Its highly possible I'll do the fat ...
