LSE Gain margin
Hi,I am using a crystal from AN2867 (ECX-.327-CDX-1293). I'm having trouble starting LSE on stm32g474 mcu.When I calculate gain Margin, I reach 1.24. The expression in the application note also tells us to be careful that the oscillator transconducta...
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...
