About starting and stopping a timer by an encoder timer

Incremental encoders are known to have problems for speed measurement at low speeds. For this, period measurement at low speeds is recommended.The following statement is taken from RM0440 page 1158. What I want to do here is to start another timer in...

bxCan Filtering

I've been reading several forums posts about filtering, and other resources such as:https://community.st.com/s/question/0D50X00009XkfSlSAJ/can-filtershttps://blog.csdn.net/flydream0/article/details/52317532I get the gist of this.CAN_FilterIdHigh is t...

I generate a PWM signal on a pin going from duty cycle 0 to 100 and back to 0% to generate a sine wave using an LC Filter. When I connect the LC filter, the output is still an PWM with some spikes. C = 147µF L = 47µH f = 1,91 kHz

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...
