Hi, i want the communication between stm32f411re board and raspberry pi 4. i tried to do with uart2 through USB cable it is working fine. but sometimes it is not able to communicate properly. there is a delay while communicating sometimes. will i2c o...
I am writing an embedded software project that includes BLE GATT protocol with stm32wb15 mcu.Based on the "BLE_HeartRate" example, to use stop1 and standby in the project;I activated "CFG_LPM_SUPPORTED 1" and "CFG_LPM_STANDBY_SUPPORTED 1".Question 1I...
Can STM32L431 configure the RX of the serial port to EXTI wake-up in STOP2 mode? Why can't I wake up? And idle interrupts cannot be used either. The manual states that the EXTI and RX pins have been connected together in hardware, but the STOP2 mode ...
Hello there! I'm trying to build a blinky program using make I'm using HAL, and the CMSIS V2 FreeRTOS ports/sources from https://github.com/STMicroelectronics/STM32CubeF3/tree/master My program compiles, but it doesn't blink, and I have no idea of ho...

Hello,We are currently developing a device based on STM32L0 MCU. We would like to implement a USB device functionality in it. The problem we have is that we don't know what USB VID and PID to set for it, since we don't want to buy our own, since this...
Hello community,I am having some problems getting USB to work on a STM32L496. Maybe you can help me or have some tips for me.I have designed a custom board that should provide access to some sensors and the CAN bus via USB as a COM interface.The boar...
I am trying to launch a dma of the input capture of the timer2 ch2 latched captured register to a memory buffer. I am using the DMA to allow me to record 75 captures so as to be able to determine the time for 75 cycles of a 500 KHz input signal. Set...
fresult1 = f_mount(&myFATAFS, SDPath, 1) while(FR_OK != fresult1){If I remove and reinsert the SD card the f_mount return FR_DISK_ERR instead FR_OK.If I restart the project all is OK.I have the SD_CARD present pin, what can i do when the card is disc...
Hello Together, I have an issue regarding my STM32 Project I tried different things and do not get any glue...I had an project with FATFS Lib and SDMMC2 in 4bit mode and it was working fine. After trying to merge the IOC - settings into my bigger pro...
