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....
The Simulink and library c files implement a luenberger state observer in a FOC system.https://www.st.com/resource/en/application_note/cd00154076-luenberger-state-observer-rotor-position-estimation-simulink-and-software-library-stmicroelectronics.pdf
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
