Hi JP, nice project!
would it be possible to also make it work as an analogue sampler?

I will keep watch this project progress!

Any chance you can share this in the mbed dev site? I would like to try it with the STM32F411RE and would be easier to just compile it online.

Thanks.

Hi, @jpbarraca nice work on making the NucleoF401RE more useful :)

I'm having trouble with the capture on LogicSniffer and keep getting "Capture Failed". When I looked at your code, it seems that there's no function to return the captured value from inside Sampler.cpp. I later found this

        case SUMP_ARM: {
            sampler.start();
            break;

and changed sampler.start() to sampler.arm(), got it working once, but after that it failed to capture again. The board appears hung after I start capture. If I stop the capture and click Show Device matedata, it will fail. Using console showing that the board is not replying at all. Any idea where to look?

I got linked this by someone looking at F401RE-NUCLEO

I knew this was going to be a mess when files were ending with .cpp, but I was not prepared for the mess that I saw inside sampler.cpp.

Did you know pretty much every STM32 has GPIO DMA which can be triggered from a timer? You setup GPIOx->IDR as src, whatever memory buffer as dst, and each timer tick would transfer the data. With ACCURATE timing.

Hello, there, did you ever try this on PulseView?

I dont know what I am doing wrong but I am trying to make my STM32F407 be a logic analyzer, at first I tried flashing this on it but no usb2serial device was ever created ((I am using StmCubeIde, never used mbed so I dont realy know what I am doing with mbed (am on windows so I dont even have required toolchain to build this, so as a PoC it would probably be easier to do it on STMCube first

Then I found this: http://slemi.info/2018/03/26/stm32-logic-analyzer/

Which has some prebuilt firmware: https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/logicdiscovery/LogicDiscovery.bin

But this is also using some wierd enviroment (its not importable into STMCubeIde), so again I cannot debug or tweak it

But at least this one showed as USB2serial device and was detected in PulseView, but then I got no logic trace (I did hit Run and stop multiple times but no dice), I tried every pin on PD io (PD1-16), and I tried to simulate logic with button press (connecting wire from eather PD1 to GND or 3V to simulate logic), but nothing, trace was always empty, so I am suspecting that I am not configuring my PulseView right

So I am trying to get my baseline right but I guess I am failing somewhere but dont know where....

Also tried LogicSniffer: https://lxtreme.nl/projects/ols/

But this program doesnt even start on my windows machine

So the question is: if you have a working firmware (which I think I do, I cannot verify that),, how do you configure your SUMP client to see some logic (because right now I only see a blank trace)?

Thanks for Anwsering and Best Regards
