We have several STM32f030C8s that refuse to start if the ambient temperature is 40deg C. Below, say 20 deg C, they start and continue to run up to and beyond 40 deg c ok. Applying a reset on a stalled processor brings it to life. Is this a known p...
I am using STM32F103C8T6 for counting rotary encoder pulse.My Encoder PPR is 5000.But when I program for timer1 as encoder mode and show count on segment it shows 20000 pulse per rotation it is 4 times higher than the actual value. What should I do t...
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 ,...
