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...
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
Hi,We're begining a port to STM32G0 line and I understand these have a built in bootloader.I am able to enter and activate the bootloader using the Flash Loader Demo GUI.However when I come to the step of selecting the MCU it appears STM32G0 is not s...
Hi to all, i'm using the TIM2 channel 1 configured as "Output Compare No Output" with mode "Compare on match" and i need to read on the fly its internal logic state as it was a normal output compare with GPIO output.As far as i understood the related...
i did purchased a demo board stm32h750b-dk Demo Board, and i use USART1 ,Tx -PB6， Rx- PB7. it works well. no issue at all. but i need use USART2, Tx-PD5, Rx -PD6(expand CN2 STMod+ connector) . it no function at all. all setting - baud rate and other ...
