Continuous SPI transactions using DMA
A little background first. I'm use the STM32F412 in a custom design and not using STM32Cube packages.What I want to do is continuously transmit/receive a fixed number of bytes on a SPI interface (master) using DMA with no software interaction (i.e. n...
Resolved! ADC Sequence conversion not working on STM32G030. Only a single EOC and EOS event when CHSELR = 0b111.
I have tried multiple different configurations, software trigger, hardware trigger, the only way to read ADC channels in sequence is to use DISCONT=1 and trigger each reading individually. I have minimized my project to a testcase where a software tr...
How to external supply Nucleo board with 3V3 in combination with using ST-Link Debugger via USB
Hi, I am using the Nucleo Board STM32G071 and I want to supply the board with 3V3 from an external source. At the same time I would like to use the ST-Link debugger that is on the Nucleo Board and I would like to supply the debugger via the micro-USB...
Why does I2C address flag clear fails during flash write STM32G0 ?
Hello,I'm trying to write runtime data in flash without disrupting code execution.I'm using a STM32G0xx, on a custom PCB with a custom bootloader. STM32 is communicating as I2C slave with another device.I have no problem erasing and writing the flash...
STM32H730 SPI clock (SCK) bug
Hello.I have noticed a SCK clock error on the SPI bus in the STM32H730 processor. It may be due to the HAL library I am using (v1.10.0).My SPI configuration (SPI2 in this case) in CubeMX:I use SPI in Polling Mode. I send 8 bits of data using the func...
How can I analyze the reason of a randomly called HardFault_Handler()
Hello Community, I have a STM32L051R6T6 CortexM0+ MCU on an customer Board and I#m developing an application for it in CubeIDE and C++, using HAL-Driverlib. It's reading from 2 UARTS by interrupt, verifying the data, converts it to telegram-objects a...

Resolved! Where are the project-files, empty folder?
Hello,I have created a sample project from Stm32CubeIDE, but there are no files in the specified location folder, see attached image.I do not understand this? Where are the files? How is this linked?Thank you
What's the max voltage tolerance when STM32 is not powered?
I'm confused with the max voltage tolerance of STM32's GPIO. In the datasheet, it states the max voltage of Vin is 4V for TT_xx pins. But in AN4899, it states they are Vdd + 0.3V. You see, the former has no relation with Vdd, it implies they will tol...
