Hi,I'm trying to generate a serial data pattern in STM32H753 for WS2812B LED chip. I did it before with STM32F2, as the TIM, GPIO & DMA2 are within the same data bus matrix, i'm able to use TIM module events as a trigger event for DMA, and start movi...
Hello everyone ; Please if someone from ST could confirm : We have a shortage of stm32f429 and the given lead time is about 80 weeks ; so our production will be stopped for 1 year; to solve this we decided to revise the design of the board and cho...
When I use Keil MDK V5.30 build target file,it cames. So how can I solve it.
We cannot purchase microcontrollers. No distributors. Nowhere. When will the problem be solved?
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...
