Hi,I am playing with STM32H747 dual core. I used the example code in DISCO. I am able to bring up the two cores and light up the LEDs from both cores without problem. HSEM also works fine.Now I am trying to write data to SRAM (0x10000000) from one co...
Hi,I would like to design a debug LEDs for UART/I2C communication (STM32F103), the purpose is just to see wether the communication is working or not, through a LED, here is my schematic, My questions are : 1) what is exactly the output voltage on Tx ...
I need to use the HRTIM for it's 10 phase synced outputs, but at a lower speed than what pre-scale and period can cover.I have TIM1 producing the base waveform I want, and now I need HRTIM counts to be based on that, instead of the CPU clock. I found...
Hello!I am going to use stm32f722vc MCU and QSPI in my design. Before designing PCB I research QSPI on available hardware: board with stm32f722vc MCU installed and all GPIOs available on headers. I am trying to execute indirect read mode to fetch GPI...
Hello, I would like to generate an event at 40 Mhz or every 25 ns. I have an algorithm that generates a very particular square wave shape. That's why I can't use PWM or DMA transfer. I use a STM32F769. Thank you for your answers.
Hello.I hope u are good. My question is:Is there a way to get an interrupt when data is changed that in Backup RAM?
Hello,I have defined the system as The APB1 CLK is defined by 45MHz as shown bellow.The Usart2 periphery is on the APB1 bus. By the full code attached bellow the USART2 and gpio settings are as following by the printscreen from the reference manual.h...
Hello, I'm using STM32F412VG microcontroller and I'm evaluating GPIO locking feature. Here is a code snippet with my test: GPIO_InitTypeDef gpio; RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOD, ENABLE); GPIO_StructInit(&gpio); gpio.GPIO_Mo...
Hello everyone,I am currently extending a legacy software, for STM32 ; it is for : "stm32f103cb", with Atollic TrueStudio 9.3 I want to add IWDG (independent watchdog) ; to do so I generated a new project using CubeIDE, latest version, driven by a pr...
Need Samples source code for CUSTOM UART BOOTLOADER based on STM32G081 & STM32G474, if anyone is having please share also request to share APPLICATION NOTE doc. for UART CUSTOM BOOTLOADER based on STM32 Cortex M0 core
