NUCLEO-H755ZI-Q: "No STM32 target found" error via ST-LINK/V3 (STM32CubeProgrammer)

Hey everyone,I'm having a rough time getting my NUCLEO-H755ZI-Q board to talk to my PC. Whenever I try to connect using STM32CubeProgrammer or debug from STM32CubeIDE, I keep hitting the same error: Error: No STM32 target found!I'm using the onboard

STM32G484 HRTIM: external-event-to-counter-reset latency and conflicting RM0440 timing values

Hello,I am using an STM32G484RE with HRTIM running at 160 MHz, configured as follows:Timer B runs continuously with prescaler HRTIM_PRESCALERRATIO_MUL32. External event EEV7 comes from GPIO PB4. EEV7 uses rising-edge detection, with digital filtering

Misprints in RM0090 Figure100 and Figure148?

Here the UIF waveform shifted to high when counter register equaled to 0x02. Isn’t it supposed to shift at the moment the UEV is set? Figure148 also has this problem. And I traced back to the earlier versions. As far as I can reach, the figures were

STM32U5G9 – 90° rotated display without a second framebuffer (LTDC / GFXMMU / GPU2D)

Hi,We’re using an STM32U5G9 with a MIPI DSI panel (driven by the LTDC through the DSI host). The panel is 800×600 and scans in landscape, but it’s mounted rotated, so the user sees a 600×800 portrait image. The panel controller can’t swap its scan di

STLINK-V2 VAPP Pin - Is this an input or output? If the STLINK is 3V3, how do I connect to a 2.5V target without damaging it?

Hi all, I have designed a target board that operates at 2.5 to 3V. Is the STLINK-V2 SWDIO and SWCLK 3V3?Will it damage my board?Is the STLINK VAPP pin an input or an output i.e. does it sense my target supply voltage and level-shift accordingly?If so

Set a preferred IDE - and other options?

Rather than having to select my IDE every time I create a new Project, it would be nice to be able to set my own default.Similarly for other settings; eg, I always like to have the generated code as .c + .h file pairs.

What Is the Best Way to Handle I2C Communication Errors on STM32?

When using I2C peripherals with an STM32, occasional NACKs or communication timeouts can be difficult to diagnose.How do you usually approach debugging these issues? Do you start by checking the bus signals with a logic analyser, reviewing the timing
