STM32 Internal Flash Write/Read Failure

Hello everyone!I'm writing a STM32F446RE-based flight computer for a rocket. I want to use internal flash memory to keep some key data like base pressure or flight time. So if a power failure happens, the system can keep the base data.These are the t...

Is STM32L475VGT6 and STM32L471VGT6 full compatible ? I would like to put the exact same binary made from an L475 to an L471. From my test It works perfectly fine. But is there any hidden drawbacks to do it this way ? Do I need to generate an L471 bin ?

MHz frequencies on OUTPUT

hey thereI have a stm32f103 blue pill board which I wish to generate MHz frequencies on pinC13.I have used TIM1. it starts and interrupts and on each interrupt I toggle PC13like sovoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(hti...

Help with debuging a for statement in BluePill

Hi, I'm using a base64 library to convert my data to my base64 on STM BluePill. everything works fine, but after 5 minutes i receive an imprecise data access violation hard fault error on a for statement. i'm using main loop to run my code every 1 se...

How to use the STLink BRIDGE API - UART bridge?

I want to use the STLink BRIDGE API and setup a C++ project. So far the GPIO worked fine, next I want to use the UART. I found the following Warning in the docu: "UART "bridge" is not supported on the STLink USB bridge interface. This functionality i...

Can anybody help me how to translate this for my nucleo?

Internal temperature sensor shows big offset at temperatures > 50°C (STM32G474VE). Is this common knowledge and if so is there some form of formula to correct this?

Setup:Using ADC1 with an ADC frequency of 50MHzSampling time of internal temperature channel = 640.5 cycles = 12.81µs (> minimal sampling time of 5µs)Conversion triggered every 1s by softwareUsing injected channel since regular channel conversion is ...

Better clock output (instead of MCO)

Hello, In my design I would love to variate frequency to camera sensor. I did this in the past with MCO, but it is giving me very large step, so I can't place camera to any frequency I want, usually HSE, or PCLK/4 or 8.Can I use SAI interface and ded...

Is there a way to debug and run a program on a Nucleo-g431kb if I don't have an st-link?

Hi, my tutor gave me a Nucleo-g431kb to practice with. I tried running a code on it with IDE-cube but the debugger alerted me that the st-link isn't connected. I don't have an ST link, but my tutor says that I don't need any.I'll add that the red LED...
