HI Team, We are evaluating the part lifecycle status and SCM positioning for the same. This Bom we are working one of our medical customer NextPhase Medical in United States.For the MPNs that are on BOM we would like to assess the following informati...

UART RX/TX inversion using UART_ADVFEATURE_SWAP_ENABLE doesn't work without UART_ADVFEATURE_TXINV_ENABLE

Hello!I'm working with a STM32 F777IIT6 (F7xx) MCU, and need to invert one of the UART RX/TX pins. Per the driver's instructions (stm32f7xx_hal_uart.h), I added statements to initialize the UART_HandleTypeDef structure's AdvancedInit with the UART_AD...

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...
