Hello,I need to connect STEP/DIR driver (DRV8825 to STM32F103) for driving one axis stepper motor. I will use buttons for moving and I need to set acceleration and deceleration profile. Do you have some experience what way of pulse generation I shoud...
I config timer'mode is TIM_OCMODE_ACTIVE , start enable ,can output waveform,but enable more than one time , only output the first corresponding waveform .why behavier so ?but when I config timer TIM_OCMODE_PWM2( or TIM_OCMODE_PWM1 ),enable and di...
I am new to STM32 and had some general questions what answer I not find described in any IDE tool help nor with Google. What is easiest IDE tool and procedure to transfer part of ST released example project form one MCU type to other MCU what had har...
Hey, I am trying to understand timers, everything goes nice, but I have a question in my mind.I am able to set the prescaler and period values according to my purporse, but I can't use the internal clock division effectively.My TIM2 clock signal is 1...
Dear Sir/Madam:I try to use write and erase a sector with interrupt enable.writing interrupt work , but erase interrupt does not work and cause the system reset after hunging for a whilethe reason I use interrupt, is to avoid the erase holding system...
How to config Timers when I want to use it to triger ADCs, May I get an example？STM32F103have already been solved
I'm using an old STM32F103RD with SPL v3.6.1. I'm confused with the value to put in TIM1_CCRx for a giving PWM frequency.Looking at \STM32Cube_FW_F1_V1.7.0\Projects\STM32F103RB-Nucleo\Examples_LL\TIM\TIM_PWMOutput\Src\main.c: /* Set compare value to ...
So I just started to use stm32f103 MCU that I have but for some reason I code doesn't go into the TIM2_IRQHandler.This is my code:.thumb .syntax unified .equ GPIOB,0x40010C00 .equ RCC ,0x40021000 .equ TIM2 ,0x40000000 .equ NVIC ,...
Hello all, I'd like to know if I'm making full use of the FPU on an F730 using SW4STM32/Eclipse. In project properties i set floating point hardware to fpV5-sp-d16 and the ABI to hardware. I also define __FPU_PRESENT & ARM_MATH_CM7 and set the libra...
Hello everyone, so what I’m going to do is displaying the value of the temperature on the LCD of the STM32F413H-Disco with a PT100, i wrote this code:int value;char getvalue[20];...MX_ADC_Init();HAL_ADC_Start_IT(&hadc1); (I choose Interruption becaus...
