How can I tell if a part number is RoHS compliant by the marking of the sealed package?

Communication problem between STM32L432KC to an Ebyte E32.

Hello,I have a project that sends a signal between master (stm32 and Ebyte+antenna) and a slave (another stm32 and Ebyte+antenna) using UART (baudrate 9600) (The communication between the Ebyte and the antenna is fine).My code is fine, it is not comp...

Hi, I am connecting the STM32H7 with the SIM7600 Chip by USART. Do I need to choose any specific clock frequency for the STM32? I am asking because in the article that I am reading the clock freq is 72 while the minimum allowed freq of my Micro is 96.

I am not sure that choosing the wrong clock frequency would affect USART communication

Resolved! On the STM32U5xx, how many cycles does the MDF need to process a sample?

In other words, what is the relation between F_RS (and possibly F_PCM) and mdf_ker_clk in DFLT? I use every block in DFLT: ADC1 -> DFLT (CIC, offset, scale, RSFLT, HPF, INT) The reference manual mentions only the RSFLT block with up to 24 ticks, but ...

Resolved! Is there a simpler way to compute the gain factor in the SCALE stage of the MDF?

To me, it looks like each gain step shifts by "half" a bit, so we could compute the gain asfloor((DSfilt - DScic)*2);e.g. with RSFLT as target and Sinc5/Dec5 + 14bit ADC1:floor((22 - 25.6)*2) = -7;

Flash memory problem in STM32H755ZI

Hello everyone, I am having a small project as follows: When I press a button the program jumps to a new program which is located in a new address space. I have successfully tried with STM32F4 series but when switching to STM32H755ZI series which is ...

Hello, we are currently using STM32F072RBT6. Does anyone know if these products need an export license and if they fall under the Dual Use category? Thank you in advance for your answers

Resolved! How can I distinguish between STM32F1x medium density devices?

We replaced in our product the STM32F102 MCU with STM32F103 without PCB modification. The 103 contains more RAM and can run at higher frequency and we would like to use the extra resources but there is a criteria. We should use one piece of software ...

MPU Setup on STM32F4 MCU failed

Dear Forum,I am setting up the MPU of a STM32F401CE using a bare metal system. All tasks and handlers run inPriviledge Mode, therefore I want to enable certain areas for priviledged access, background should cause a memfault. I use the following memo...

Resolved! About STM32F205VET6 bypass capacitor
