STM32 MCUs Products

We are trying to dump code into STM32F722ZCT6 controller using ST's bootloader " Flash Loader Demonstrator" . We have attached screenshots of our trial. Please guide us to proceed.

STM32L4R5 Internal Flash Write Protection ( Permanently lock flash sector for write )

Hello, i am going through the the technical reference manual of STM32L4R5 and i am bit confused about the Flash Protection feature, specifically write protection feature.my product requirement is to avoid the modification of my executable ( bootloade...

Can we set the OSPEEDRy[1:0] = 01 when we use SPI Clock 12.5MHz?

stm32h743iiWhen we set the OSPEEDRy[1:0] = 11 we have glitch spike (undershoot) on clock and data. it was improved when we set OSPEEDRy[1:0] = 01.In datasheet SPI interface characteristics page 307 saidOutput speed is set to OSPEEDRy[1:0] = 11.

STM32H750B-DK not able to program using system workbench

I have purchased STM32H750B-DK. I am using system workbench for stm32 as IDE. Now i downloaded STM32CubeH7 library and trying to download GPIO_IO_Toggle example program into this board but getting the error as below:17:31:42 **** Programming project ...

Circular DMA seems to "doublebuffer" (STM32F427)

What is it that I've been missing...I set a timer to trig 7-channel ADC with DMA. The DMA is set to make 7 16-bit to 16-bit transfers circularly. It seemed to work fine, but some data started to corrupt. So I made the 7x16-bit buffer 4-fold (28 16-bi...

SDMMC 4 bit mode with DMA (STM32L4R7)

Hi,I'm trying to configure SDMMC module using DMA since I'm using FREERTOS. But in STM32CUBEMX, there is no option to configure DMA settings under FATfs.So, I'm trying to setup the DMA configuration through code. I can see that there is no definition...

STM32CubeL4 SubGHz P2P missing data

Hi,I have two B-L475E-IOT01A boards and I am testing the SubGHz P2P application available in the STM32CubeL4 package. Whenever I press the User Button on one board the led LD1 on the other board blinks, and as the ACK command is received the led LD1 ...

Is a schematic available for X-NUCLEO-LPM01A?

 I want to calculate the measurement accuracy.

VREFINT_DATA

I'm using the STM32F0 Discovery (STM32F051R8T6) and trying to measure temperature via an ADC input. We're using the formula: VChannel = (3.3V * VREFINT_CAL * ADC_DATA) / (VREFINT_DATA * fullscale), but we are unsure what to use as the VREFINT_DATA va...

Configure DMA for MDMA H7 dual core

Sorry to be asking so many questions, but these dual core h7s are hella complicated and the documentation can be a little vague.I am trying to understand how to set up the dmas to work with the mdma. I think i get the dmamux and how the mdma works wi...
