The solution was to hard reset the SPI module using RCC_APB1RSTR register.HAL includes macros for this:__HAL_RCC_SPI2_FORCE_RESET(); __HAL_RCC_SPI2_RELEASE_RESET();With these it completely resets and can be initialized again!I'm using SPI slave mode....
STM32L452 ADC1 single-mode works with DMA1. ADC results are higher than the actual Voltage by around 25%. Any possible directions?
Hi everybody,I'm working on the stm32H747/757, and later will work on STM32H753.We have a test-driven development attitude and I was curious, is there any way to emulate the MCUs of H7 series?Thanks all :)
HiI have a chip in main board that can be programmed using SWD interface.Can I use the SWD of the STM32F407 to program another chip (and not just for programming and debugging the STM32) ?If so - Are there any HAL functions ?Thanks

Hello,I am working on Nucleo-h745ziq board. I enable cm4 to cm7 event and cm7 to cm4 .I enable the timer in cm4 and cm7 .But the event it doenot occur in cortex m7 ,my programme is below please help me.void HAL_TIM_PeriodElapsedCallback(TIM_HandleTy...
Hi folks,,, I would like to understand how much is the effort of doing the porting from MCU STM32F746ZG to MCU STM32F767ZGT6 ...How many changes I should made?Thanks a lot for this information but now the situation with the supply of micro as you kn...
Hello every one , i'm using a STM32L100RX, i am using PC11 and PC10 ports as USART3, so far everything it's okay, but i need to use the same usart (USART3) on the PB11 and PB10 pins...i need configure these pins in runtime because i have another devi...
Hi folk, how's tricks?i need some help from you happens following:I have a UART3, but this UART work's on PORTB and PORTC pins, so i need to use this uart some times on PORTC and other times on PORTC, so i reconfigure the ports in runtime to get this...
Hello,I am using DAC module of STM32H743ZI2 micro controller to generate sine wave of 8KHz frequency I am using Timer2 for this setting using APB1 bus of 150MHz and prescaler of 74 and ARR register of 1.>>The issue I am facing is jitter in the outpu...
