STM32 MCUs Products

Can we denied access of a peripheral for one of the CPU on the stm32h7 ?

Hi,I am working on the dual core stm32h7 and I wonder if we can prevent one CPU to have access to a peripheral enabled by the other CPU. There is a way to do this without using MPU protection on the peripheral registers ?

The DMA transfer only the first byte from ADC1 (STM32H735)

I configure the ADC1 of the STM32H735 like bellow:The ADC Clock = 20MHzADC_HandleTypeDef hadc1; DMA_HandleTypeDef hdma_adc1;   /* ADC1 init function */ void MX_ADC1_Init(void) {   /* USER CODE BEGIN ADC1_Init 0 */   /* USER CODE END ADC1_Init 0 *...

Do STM micro controllers have SENT peripheral?

I am looking for a micro controller which has SENT peripheral in it do STM have any such microcontroller?

Hello, Anybody know where I can find a tutorial on building the STBLE_Sensor app for Android? Thanks

STM32F DAC not driving voltage to more than 0V

Hello,I am using a STM32F429I-Discovery board for a project involving the use of both DAC channels. I am using the Peripheral driver library for faster coding. Despite having configured everything as specified in the docs and the library I cannot get...

[STM32F303] ADC1 watchdog high Threshold limited at min 3500???

Why is there such a limit? As good as this watchdog is, this limit makes it kind of useless. Its it a typo? It worked with 3300 though, when altereing the generated code.

i am designing our stm32l476 board and want to make sure beforehand that i can use Vref refference voltage in the AD conversion or not. i think internal ADC use is available while vbuf+ is conbined with vdda in 64pin package. am i right?

Why does STM32 sometimes hardfault on reboot (thumb vs arm instruction)

STM32L496 micro is hard faulting when power is cycled, but only on some builds of firmware, others are ok. I've been able to track it down to a specific path in the assembly, what looks like is happening is a vector table address is loaded into R3 wi...

Capture egdedirection on input capture with dma

Hello,i am using the STM32F410CBUx and want to detect rising and falling edges with the Timer 5.I get these values with the help of the DMA because the signal edges are close together and i need accurate meassurments. The edges occure all in a short ...

How to use an external signal to trigger ADC on H755ZI?

 Hello,As the title says, I need to use the ADC's external trigger designator pin to trigger the transition. I have done the necessary steps on Cubemx but my code still cannot work.Looking forward to hearing from the forum.Thanks,HAILV /* USER CODE E...
