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...
Do you know the specified values for tr, tf and THSE?
Hi community @STTwo-32 ,I am using stm32f407vet6 board I am new to stm32 board.I wrote an Hello world program in STM32cubeide and i try to debug the code.I bought an ST-link v2 from online.when I try to debug the code it says frimware upgrade require...
Hello,Where can I find a BSDL file for STM32F205ZET7?
Hello forum,I'm (still) working on a data acquisition system based on STM32H743XIH6 MCU, I'm pushing the 16bit ADC to the limits and I'm stuck on a corner.Let me summarize first the actual code:1) TIM1 trigger every 1us ADC1 acquisition2) ADC1 acquir...
The chip model we use is STM32L496VG. Our customer reported that the machine became unresponsive (bricked) and couldn't power on after an OTA upgrade. After receiving the machine, we used STM32 Programmer to read the flash, which prompted chip protec...
Hello,I am using the STM32H745I-DISCO board for my project, which requires both TouchGFX and CAN FD functionality. However, I am encountering an issue with the clock configuration.I need to synchronize the Nominal Baud Rate to 500 kbps and the Data B...
dear ST and/or Users, we’re using STM32H743I with a requirement now to store several bytes of data in non-volatile memory. We have known-working code for the existing application, and need to be assured it is not affected when eeprom emulation code...
I'm a beginner and I don't understand the datasheet very well. Can I externally power my STM32 F446RE from the VDD pin (the one opposite E5V in the pinout)?Sorry for the banality, but I only found info for generic GPIOs.Dar
