Trying to read out a resistive touchscreen right now. To keep everything as simple as possible for testing I created an empty project in CubeMX just for testing this and set up all the pins in a static fashion (No reconfiguration at runtime)Measuring...

I'm currently working on a project that needs to decode JPEG's and do so as fast as possible, natuarlly I've looked for alternatives to the libjpeg offered by CubeMX and stumbled upon Libjpeg Turbo which uses SIMD instructions to optimize the de-/com...

Hello there,I've prototyped a custom PCB, but I'm having issues getting USB to work, Windows is unable to read the Device Descriptor.The IO, from what I understand, is connected correctly and the generated code is (seemingly) successfully able to ini...

Like I've said, Ive tested a lot of things, different values for `HAL_MAX_DELAY` is one of them, regardless in my case it is a hardware issue as vref+ was not connected to vdd / vdda due to poor soldering. Having corrected that it is now working.

I'm slowly running out of things to try. Connected the 60MHz clkout line from the PHY to the STM with a jumper and cut the trace to prevent any possible crosstalk from that line, same resultI cut the only trace which goes across the board pretty much...

Got a 24M crystal, swapped out the 25M one, changed the clocks so the HSE is passed trough aaand... Now I cant even get it to detect on Full Speed. Back to square one I guess.Edit: Actually that was my fault, its the same behaviour as before now.

I was just curious, maybe you knew something that I didnt. Thank you regardless. I'll pursue trying to solder on a 24MHz crystal as I honestly dont have any better idea for something that I could try out.

How would using the system clock help me? It would still be going trough the PLL, just like the clock configuration in the entry post, and I'd need to run the MCU at a lower speed. I've tried it regardless with the same result.
