STM32 MCUs Products

Hi , I would like to know if there is a way to use DMA to get the TIM1 advanced timer update events ? I can successfully trigger an IRQ but having problems setting a DMA to trigger on every update. I am using STM32 L4 MCU.

I am using the advanced timer TIM1 on STM32L476RG MCU. I have configured the timer in slave reset mode as given in section 30.3.26 of the reference manual. The counter resets every rising edge. I want to use this mode to measure low frequencies such ...

Hi, i would like to know which chip is under name ST A267BB (100 pin case ).

I'm using follow code:volatile unsigned int *DWT_CYCCNT = (volatile unsigned int *)0xE0001004; //address of the register volatile unsigned int *DWT_CONTROL = (volatile unsigned int *)0xE0001000; //address of the register volatile unsigned int *DWT_L...

Run Debugger in one step

hi I want to enter the debugger mode and then run the whole code by clicking 'Run' button or F5. but every time that I click 'Run' it just goes one step forward and it even enters inner functions...what should I do?

Hello, My c code is generated from stm MAT-TARGET, but when I run main file of the IDE(Keil and stm32cubeide) nothing happens on the board. Just trying to run simple blink led model.

 I am using stm32 F746ZG Nucleo LQFP 144. I am using stm32 MAT-TARGET to generate c code from my simulink model.I have read in the provided pdf by the Stm MAT-TARGET that stmcubeide is not well supported by this. So I am using Keil V5. Now after gene...

i need to create the motor profile of 86BLF03 WITH x-nucleo ihm08m1 AND nucleo f303re

i am trying to create 86BLF03 motor profile using X-NUCLEO IHM08M1 AND NUCLEO F303RE boards, i am having serious problems cause i can't find max current, vbus, magnetic.Moreover X-NUCLEO IHM08M doesn't give me any information about the phase of the c...

Hi, I am using stm32f103c8 board for development purpose. I want to interfacing SD Card (SPI protocols). using arduino ide but not working , so please tell me it is supported arduino ide . if support arduino ide then share library.
