I’m currently working on a project where I write software for an STM32F072 that will control a couple of stepper motor drivers via PWM with a bit of precision. I’m therefore using TIM2 and TIM3 to control two separate PWM outputs where I can regulate...

Here is a copy of the CAN registers. To the left is what I get when I set Pulse = 50 for TIM3 in CubeMX. When I instead change that to 0 in CubeMX and set it to 50 by putting '__HAL_TIM_SET_COMPARE(&htim3, TIM_CHANNEL_1, 50);' in code, I get the scen...

The statements contradict each other, but only because I expressed my meaning terribly poorly in the first one. What I meant to say by "If I then change the Pulse value for either TIM2 or TIM3..." was really "if I then change the Pulse value for eith...

Thanks for the reply!Indeed, the steppers do generate a lot of noise. Enough so that the STLink loses its connection when they start stepping. But I've been running this with the stepper outputs disconnected. I'm not at work today, so I can't look at...

Why does CAN reception in STM32F072 stop working when setting Pulse register for TIM2 or TIM3 to non-zero value?
