Using STM32L496VGY problems debugging easy project

Hello all,In a custom board I wrote a very simple code using stm32cube.When I start debugging it shows this message"Break at address "0x1fff1d66" with no debug information available, or outside of program code."After that I see the cursor in main at ...

Newcomer questions~VSCode Unable to write file ?

I want to add some new annotations to this stm32f429xx.h to help me understand, but VSCode tells me that I cannot "write to files", so what should I do to make vscode write successfully？

STM32L552 (non-Q) current consumption dependency to VDD

I don't fully understand one thing with STM32L552 which has no SMPS: Does decreasing the VDD from 3.3V to say 1.8V reduce it's power consumption?All the measurements in datasheet and in AN5213 are done for operation ranges and in SMPS modes I see tha...

I have an STM32F7508-DK board and have a makefile based baremetal project. Is there any bare metal USB drivers (for MSC) that I can use (not HAL drivers)?

Hello When X-Nucleo- PLC01A1 will be available to buy? Or do you tell me when i can find them? Thanks by advance. Best Regards D Humbert

Problem with the HSI clock on the STM32F091VC

Hello,I use STM32F091VC the from 4 year without problem, I have used more than 20000 STM32F091VC. Recently, I have several STM32F091VC who have a big problem of accuracy on the clock HSI. The error is about 30% ! For exemple, the STM32F091VC give abo...

Problems accessing QSI Flash with consecutive reads

I have a Cypress S25FL064 flash memory connected through QSPI interface to a STM32H753.The memory is booting in "single IO" mode (ie. classical SPI protocol with MISO/MOSI signals).In this mode I am able to erase, program and read the memory through ...

Generated LIN break is too short

Hi everybody,I am using STM32G070KB and trying to generate a LIN break. But this seems to be only 10 bits long instead of the described 13 bits. If I am right the break should be about 680µs long at 19.2kBaud. But it is only about 520µs long which is...
