Hi,I have a STM32U575 connected to an external HW watchdog which needs to be periodically fed (with a 100 ms timeout) with an SPI command from the MCU (2 bytes), and i would like to achieve this without CPU intervention (or as little as possible).Her...
Hi, I am working on an STM32 project. Our current pinout uses PA1 and PA1-C for two different GPIO outputs, but when I try to do this in CubeMX I get an error:Is it impossible to use PA1 and PA1-C at the same time?
Hello STM32 communityI'm facing an issue with my custom PCB featuring the STM32F030CC microcontroller. I've been using an STLINK V2 with opto-isolation for programming via SWD.Here's the scenario:Initial Success: After connecting power and performing...
Hi together,I have some questions depending to the qualification proccess. It is planed to use STM32L451, there is an IWDG which is, as the name tells independent, so can I assume that I can do the project without an external watchdog device, if we u...
hi,In the page 13 of the datasheet (https://www.st.com/resource/en/datasheet/stm32wb5mmg.pdf) there is limited information about the PCB layout guidlines. I'd like to know more about the layout on left side of the module in the image shown if the mod...
Posted on October 20, 2016 at 05:54Background: 1.5% of products which use STM32F107 totally dead after using 3 months;Problem: The NRST reset not function. After disconnecting the power and connecting again, the chip could recover and wo...
Hello @Sarra.S ,I have working in Low power mode; there I try to read LPGPIO pin to generate s/w interrupt to wake from Stop 1 mode. Before entering the after entering Low power mode the LPBAM feature is not working as expected. I tried with the exam...
I'm experiencing a weird race condition / hangup with an application that I've built for my STM32F407VGTx. Basically I connect to the device via a USB cable and open a terminal to type commands on the device like a CLI. Everything works fine until I ...
I am considering purchasing this for an MP3 player project that I was assigned to but I can't find anything definitive online to make me think that it is interfaceable with this microcontroller as all the examples and videos are done with Arduino. I ...
Hello,I am building an application using ThreadX, FileX, USBX and USBPD. Everyting runs perfectly until I bring USBPD in the game. Whatever I do, I always get an error when the library calls USBPD_CAD_Init().More precisely, the function fails at a ca...
