STM32F745 IWDG Refresh Problem when IWDG_RLR is less than 4

Dear All,I am trying to use IWDG for STM32F745 and I did actually. I used CT Cube MX to configure it. Prescaler is 4, Window is 4095 and RLR is 3. I checked clock configuration and IWDG uses 32kHz RC internal oscillator and count down from RLR. I exp...

STM32F7 sometimes receives 0x00 from erased Flash memory connected over QuadSPI

I'm using the STM32F779BI microcontroller with a connected 64MB NOR-Flash memory (MT25QL512ABB). The memory is connected via the Quad-SPI interface. To erase, program and read the memory i use the mt25ql512abb.c file out of the STM32Cube_FW_G4_V1.1.0...

Using an STM32F030F4 20-pin for a battery powered application with just a low quiescent touch tensor (active high) for wake-up from low power stand-by on low-to-high and high-to-low sensor edges.

I'm considering an STM32F030F4 20-pin for a battery powered application. Might a low quiescent touch sensor (output high) in conjunction with the timers/functions onboard the chip be used to wake the chip from low power stand-by on the rising and fal...

We use STM32F767NIH and see random QSPI interface failure accessing a flash.

We use STM32F767NIH and see random QSPI interface failure accessing a micron flash. The failure happens when we run diagnostic sw in a loop that does a write, read back and verify function. Using a protocol analyzer, we notice that when the QSPI fail...

32f746gdiscovery

Do i need a license to produce the clone of 32f746gdiscovery ?

How to see a graph from an array?

Hi all,I'm taking a lot of readings from the ADC, and store those reads in an array (reads[2000]).Is there a way to sohw a graph from the reads, using STMStudio or another program?

Regarding SPI DMA Rx issue when using SPI 8 bit mode

Hello,I have had an issue with SPI Rx DMA. In short, I recieve twice as many bytes as I expect when using SPI 8 bit mode (STM32CubeIDE setting), but not in 16 bit mode.A brief description of the project:Im using an external accelerometer with 220ksps...

Is STM32H743ZIT6 multicore or not

When I read the datasheet, the introduction doesn't mention the number number of cores. Digikey says this is a multicore chip. Mouser doesn't either talk about multicore.Several pages down (14) on the datasheet I can read that this is indeed a multic...
