STM32 MCUs Products

Experience with oddly silkscreen STM32s?

Got a new batch of micro's from a broker due to the chip crisis. They work and soldered down fine, memory matched, bootloader, etc. The concern about these MPU's is the silk screen and die marks are quite different.We have never seen die marks on the...

What is good to use for a “monitoring system�?? That is also going to have video feeds?

I want to create a localhost that my client can easily see a custom page on, that is displaying all the data from fish tanks. Such as, temperatures, water levels and more. What products would be ideal to use? A NUCLEO-f767Zl??? BUT, then theres the a...

STM32H743ZI UART Tx with DMA doesn't want to turn on

Hi guys, its been a while and I hope everyone is well and safe.Using a STM32H743ZIReference Manuel I am having issues turning on the DMA1 stream associated to the UART4 Tx, in this case DMA1_Stream1. The DMA is setup as a One Shot mode (Normal Mode) ...

STM32f746G_DISCO board sdram configuration quesiton

Hi, In the STM32F746G_DISCO board, FMC_SDRAM example, how to decide these parameters? Which section does it specify from sdram MT48LC4M32B2B5 datasheet? SDRAM_Timing.LoadToActiveDelay   = 2; SDRAM_Timing.ExitSelfRefreshDelay = 6; SDRAM_Timing.SelfRe...

STM32H part in Digikey stock

But will it stay available and what about other STM32 ICs.

On STM32G473, why would the ADC readings be lower than the calculation says they should be?

We are running the STM32G473 micro and are using an ADC channel to read the various bus voltages (3.3v, 5v, and 24v) as well as motor currents. All the ADC readings are lower than they should be, but not by the same percentage.I am pasting some samp...

How to set up the adc sampling time.

Hi,I am using ADC of STM32H743ZI which is configured as 16 bit, ADC clock =36.5MHz,Tsampling=1.5cycles in continuous conversion mode . I am using DMA technique to collect the data using a buffer size of 4096 in circular mode.The input is sine wave o...

atollic truestudio调试时Live Expression显示功能�?�?�用，表达�?�??示Multiple errors reported. 1) Failed to execute MI command:-var-create - ,请问怎么解决？

UART information is shifted by 1 byte when I connect my STM32G474RE directly to my PC and use a terminal program to send information to control things. It fixes itself after resetting the board.

For example, if I send 1000, it will be received as 0100 on the STM board. I send what I received in the Rxcallback function. My program doesn't work, so I know this is the case. This issue stops after I hit the RESET switch on my board. Now, my iss...
