My original aim was to prove to myself that I was able to measure execution time with cycle accuracy. In order to do that, I have 9 'test_dwt' functions, they all have same code except number of nop between 2 reads of DWT.That gives unexpected result...
Hello ST Community,I am working on an OTA firmware update implementation on STM32L496, and I am facing an issue related to dual-bank internal flash usage when the firmware size exceeds 512 KB.I would like to explain my setup and the problem in a simp...
the best I achieve so far using DWT as well as PMU is 'few cycles' accuracy. My question is, how I measure execution time such that I get 1 cycle difference when I insert a nop in the measured code ? (assuming interrupts and caches are disabled).Both...
I have a custom PCB with an STM32H563VGT6 microcontroller and an external Winbond W25Q16JVUXIQ NOR flash memory connected to the octoSPI's (XSPI) upper four pins. The problem is I can only write data to the flash memory after an erase, if I reset my ...
I want to design a baord with stm32h7b0zbt6 with extranal sdram chip W9825G6KH-6. I get PG15 with FMC_SDNCAS alt func in datasheet as below:But when I looked the PG15 alt func config I get as below info, I could not found an alternate function number...
Hello,Description: I am attempting to generate two simultaneous pulses of different lengths using a single timer (TIM4) and multiple channels.Current Implementation: I am currently using One-Pulse Mode (OPM). In my existing setup, the pulse starts at...
I am trying to get the CAN Loopback up and running on my STM32L431KCU (CAN1), I have tried to follow the: Guide to CAN (bxCAN/CAN2.0) configuration in Loop back mode on STM32 MCUs. But I am getting stuck in the "HAL_CAN_Start()" function where its wa...
Hello,here the exit of my (extended)initialization prodecure for ADC of STM32U535 running at 3.3v and 160 Mhz. Before setting ADC_CR_ADSTART, without the small delay or with the delay in line 14 and the limit for i smaller "6" like here "5" in the ...
Hello all,We are testing LPUART wake-up from Stop 2 mode using the STM32CubeU0 LL example:STM32Cube_FW_U0_V1.2.0/Projects/NUCLEOU083RC/Examples_LL/LPUART/LPUART_WakeUpFromStop2_InitWe made a minimal modification to the example:Replaced LPUART1 with L...
ST moderator: Edited the tile to add "ADC" I want to extract data at high sampling frequency ~10KHz at STM32N6570-DK, Is it possible with USART for three channels or we have any other mode for this purpose. I want to continuously stream data at 10KHz...
