Hi,MasterMCU: stm32h743iiQuestion:The scatter file is as follows: The stack and some global variables are allocated in RW_D2SRAM. After the program starts and during the handling of scatter file loading in its __main, it is found that both the stack ...
I'm working with an STM32H735 Discovery board. I have DFSDM working via the STMOD+ connector. I'm currently designing a PCB that will plug into the Arduino header to better connectorize our PDM mics, add a few additional parts, etc. and move all DFSD...
Hello :) i am working with a nucleo-h755zi.my goal is to create the following:1. M7 core running with FreeRTOS and LWIP.2. M4 Core running bare metal. after using the following instructions (https://community.st.com/t5/stm32-mcus/how-to-create-projec...
Follow-on from STM32L433RCT6 - Which external interrupt GPIO pin can I used for wakeup ?I am using the STM32L433RCT6 with a WKUP pin (GPIO PC13) to wake the MCU from shutdown mode.Does it matter which edge I used (rising or falling) ?I am currently u...
I have an STM32CubeIDE project using HAL for a STM32G071RBT6I have Port D bits 0 to 6 set up for GPIO Input, with pull-up enabled.In hardware these are connected to an 8-WAY dip switch, which when each switch is "on" connects the respective pin to GN...
I'm programming one of the dual-core STM32s (the STM32H747IGT6) and running into a situation where the CM4 is much slower than I need it to be, and I'm trying to figure out why. I'm using this short piece of code as my test bed: __COMPILER_BA...
Hi,I'm trying to get a stm32u073 to wake up from stop mode using an RTC alarm. I previously did the same on a stm32f103 which seemed to work just fine. When trying the same on the stm32u073 the controller either doesn't wake up or wakes up every seco...
I have solved the problem, but I want to know the root cause so I can solve this perfectly.I use STM32C071FBP6. Because STM32CubeIDE won't generate classic CDC VCP anymore, I use STMicroelectronics/stm32c0-classic-coremw-apps: Provides a set of appli...
Hello, ST experts STM32F407 is used on our system. PE7 is configured as an EXTI pin for both rising and falling edge. How can I accurately recognize which edge is the cause of this interrupt? Because there maybe a narrow glitch on PE7, so reading GP...
I was finishing a project that does the job of hi-speed polling from a SPI interfaced IMU chip, the frequency is about 5Khz, I know that this could be done by start a DMA transfer by software in the hardware update interrupt. But now I'm searching fo...
