STM32 MCUs Products

We are using STM32F103xB. We intend to replace STM32F103xB this with STM32F103xC, STM32F103xD & STM32F103xE. We found difference in memory map section in the "Aliased to Flash section", when comparing both MCUs. Will there be a need for Software change?.

MDMA_STM32H7xx

HI. there are two TIM1 registers and you need to move its address 0x40010034 from one register to another register 0x40010038 exactly 64bit, that is, a double word. is it possible to do this with MDMA single? the documentation is very poor. I had to...

Reading a very slow PWM frequency

Hi,I need to read a PWM that a rotating wheel generates (16 pulses per revolution) and I want to use one of the STM32F429 timers to do it. The problem is that the period goes from 7.8ms to infinite (no pulses), so I don't know what will happen if the...

synchronous communication problem

In one of our projects, we used stm32l031 microcontroller to make synchronous communication operating at 5Khz frequency. Total data length is 35 bits, 3 bits are the Id identification bit from the master device, the remaining 32 bits are data bits an...

How to use peripherals in both core?

Hello,I am working on Nucleo-h745ziq board. I am enable the UASART3 ,the intialization in done in cortex m7 and I try to use in both core,but only core 7 USART3 is working in core m4 USART3 is not get worked ,the code is as followscore m7 code: HAL_U...

New project runs but chokes in debug

Hi, I created a project in MX Cube for a Nucleo 746XG board. I set up a timer as a periodic interrupt, and one gpio. I did nolt change anything in the clock section. The code toggles the gpio line. This code runs fine, but when I go to debug it the S...

Resolved! What is the fastest stm32?

Resolved! Cannot set full PWM

If I set the Counter Period (AutoReload Register) to max 0xFFFF and the TIM capture/compare register to 0xFFFF too, I cannot get a full width output, I still get one tick on output.Is that expected?

Resolved! Is it possible to use a timer to send a on-time-pulse PWM at a frequency of less than 1Hz?

For example, sending a 1.5second on-time pulse? It would also be helpful to be able to set a delay before the pulse starts as well as the 'repetition' of the pulse. The TIMER1 does have the required features but not sure how to scale down the frequ...

Resolved! Toggling pin PE9 using SMT32F407G DISCO board

I am not able to get pin PE9 to toggle using timer1 and Channel1 as a PWM Output. I have tried different configurations for the timer with no success. The timer does run as expected, and all parameters and interrupts work. The only issue is pin PE9 d...
