STM32 MCUs Products

Is it possible to use some vectorization with STM32H753XIH6. Any help? or pointers for SIMD options on STM32H753XIH6.

I'm trying to implement a vectorized program on STM32H753XIH6. I tried using mmintrin.h for implementation of simultaneous processing of data. but seems it is not compatible with cortex-m7. Using IWMMXT gives following error:warning: switch -mcpu=cor...

Pointer value changes when not debugging, causing hardfault.

Target device STM32F407VGI am getting a hardfault that occurs only when not debugging.Using RTC_BKP registers I have tracked the problem down to a function call that passes a pointer to a struct.This struct contains a pointer to dynamically allocated...

STM32F767ZI and USART by HAL.

Hello,I have a strange problem with my STM32F767 ZI and USART communication.With CubeMX, I set USART2->Asyncronous, SYS->Debug Serial Wire and RCC-> HSE Active (crystal/ceramic resonator).So I generated a project for Atollic Truestudio and insertedHA...

X-NUCLEO-PLM01A1 - Doubt about this shield

Posted on February 23, 2018 at 18:14Hello people.I was studying the datasheet of Shield X-NUCLEO-PLM01A1.This Shield is intended to implement Power Line Communication on DC voltage lines.Why use two lines of cable pair for communication between the ...

Comparing Atollic with IAR - code size

I am moving a large existing project from IAR to Atollic True Studio for STM32 as an experiment. I got it to build and run without too much pain, but have noticed that the ELF file which is produced is *much* larger - more than twice the size with no...

How to make correct timing when using UART RX/TX and EXTI_Callback function at the sametime?

Hi, I'm using NUCLEO-F103RB board and I want to transmit data to PC using with UART.​The code below is that if I receive data from PC, the specific data is transmitted to PC.int main() { while (1) { HAL_UART_Receive(&huart2, uartRxData, 2, 1000); ...

Does CAN Masking truly mask all unwanted CAN IDs?

I'm working on the STM32F1 device and have been reading the CAN filtering and masking process. I now understand how the ID mask and filter works. I do have one question though as in certain cases I'm unsure if the filter would work 100% correctly.If ...

STM32 ADC sync with PWM

​Dear whom have expericenced STM32 MCUs (STM32F411),In my target device, ADC timing control is very important. In executing ADC in STM32 MCU,  can it be fully synchronized with PWM generated from STM32 MCU?I'd like to use PWM signal as start trigger ...

ADC can be executed with perfectly syncronized with internal PWM generated from STM32 MCU?

HSE startup timeout on STM32F103RET7

I'm new to the STM32 so I apologize in advance for the trivial question.In the following code from SetSysClockTo72() system_stm32f10x.c, the value for HSE_STARTUP_TIMEOUT is 0x0500.  What max delay (msec) does this equate to? /* Wait till HSE is read...
