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,In my project, I want to hold boot params in BKPSRAM so "Application project" can also write and read this section easily. If boot is needed, "Application project" will set boot params as required and after that it will use "NVIC_System_Reset"....
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...
