I am working with the STM32F769 microcontroller and I can see that a lot of DMA buffers are placed in DTCM in the source code I'm working with. Looking at the data sheet ( https://www.st.com/resource/en/datasheet/stm32f765bi.pdf ) page 20 I don't see...
Can I measure low pulse duration(>10ns) using the STM32H Hrtim?Hi all,I'm new to STM32H7 development. So I'm hoping to get some help to start.I need to measure pulse duration in 5- nanoseconds resolution or less. I then need to transfer the measured ...
I am working with the STM32F769 microcontroller and very rarely I experience some strange issues with an SPI slave and I suspect it's related to congestion on the bus matrix (other, primarily DMA, transfers ongoing at the same time). Is it possible t...
Hello,I get an issue with the USB HOST configured on my STM32F2This USB HOST driver works well in my case, but it appears that the interrupt OTG_HS_IRQHandler is called too frequently (when I plug a device on the USB HOST post) and it's flooding my C...
I'd like to try using the STM32L011E4Y6TR in a new design. However, the HSE input has only one pin (RCC_CK_IN) and I'm not sure how to use it with a standard 4 pin crystal that typically connects to 2 mcu pins. Can someone point me toward a referen...
I have set up TIM2 as a slave triggered by ITR1, But have not started any other timers to generate a suitable TRGO to trigger TIM2. However, when I run the software I can see an output from TIM2 as soon as it is started.If I change TIM2 to be trigg...
Hello st community, I work on stm32F4, and I use with RTC for date time.When I write in RTC a wrong day (for example 30 Feb 2023 or 31 Apr 2023) I havent a error in the result.It is possible to ask if the data is correct ?if (HAL_RTC_SetDate(&hrtc, &...
Before starting out on further investigation, I'd like to ask if anyone has used a USART and printf redirect on BOTH cores at the same time? I'm under the impression that the "Resource Manager" library might be part of the solution, but really unclea...
now I'm about to try 2 PWM outputs on STM32G4, one is 1/2 time-base delayed from another one.I think that it is difficult with using only 1 timer, and if using 2, is it possible?maybe like following.. using TIM2 & TIM3 for example, both are PWM gen...
Hi togetherWe use a STM32H747 MCU with an external NAND SLC Flash on the FMC bus.In the reference manual in chapter "23.8.6 Computation of the error correction code (ECC) in NAND Flash memory" and some pages later in the description of the ECC regist...
