Count External Pulses Using Timer

Hi All,First post :beaming_face_with_smiling_eyes: I want to count external pulses with a STM32F105 or STM32F405 using the HAL library. I want the external pulses to increment the timer counter. I want to avoid using interrupts. Instead, I want to re...

Hello stm. in recent years in projects I have mainly used stm32f746zg microcontroller due to excellent performance, but it seems to be doing it less and less availability and increasing prices in the market time principle, so I wonder if there is a pin to

TIM_DMAError with ErrorCode 1

Hi, I am trying to send WS2812 LED data as PWM signal using DMA. All works on STM32F091/STM32F103, but when I try to do it on STM32F407 sending via DMA fails.My TIM1/DMA/NVIC settings: I am trying to call:HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, ...

I had some issues with USART3 with nucleo-H723. The board's UART3 is connected to st-linkV3，When I using USART3 to send data in keil, it works fine，but when I use Clion is, the PC serial port shows packet loss, and I want to know what is the reason an

memcpy vs split SPI transfer

Hello,I came across this question while writing a driver and I would like to ask what is your best practice in this regard. So lets say you want to interface with an chip via SPI. To perform any action, a command byte or a sequence of commands is req...
