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...

STM32G474VET6 FMC

All health!I tried to connect the display on ILI9341 to STM32G474VET6 using FMC. There were no problems with stones F1, F3, F4, F7. And with G4, an interesting plug is obtained - for each byte, a 0x00 byte is added. I read Eratu - there is nothing. I...
