Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
When using a USB CDC device, especially at high data rates, there is a possibility for packet loss. This post illustrates the issue with what I consider convincing evidence. This isn't a STM32 bug, but it's something you may encounter when interfacin...
Good evening, now that I can ping my F767ZI board with my laptop, I'm trying to use some tutorials on the web to be able to send data (numbers or message strings) to a server (Hercules software set as a TCP server), but I'm having some difficulties (...
Hi everyone,I am working on a project with the NUCLEO-H7S3L8 and trying to read 2 ADCs simultaneously in Continuous Conversion mode using HPDMA.The Goal:ADC1 & ADC2: Reading 7 channels each (14 channels total).Mode: Continuous Conversion, Circular Mo...
I have updated the STM32L4 HAL drivers to V1.13.6 / 14-November-2025 (1.18.2), which has broken my implementation of HAL_UARTEx_ReceiveToIdle_DMA.Is this a fault in the new HAL drivers or does user code need to be updated inside the HAL_UARTEx_RxEven...
I am trying to establish an ethernet comms with the STM32F207ZGT6 MCU.I have configured the pinout in CubeMX and followed various online resources for implementing LWIP, however I have had no success in discovering the device on my network, and thus ...
When I call function HAL_FLASH_Program twice with the same Flash address, the second call is ignored. See test code below.int8_t buffer1[16] = {0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF};int8_t buffer2[16] = {0xF...
I'm using the X-CUBE-EEPROM library on my STM32C031G6Ux to store keys in flash memory. I configured eeprom_emul_conf.h so that the emulated EEPROM starts at 0x08007000, with 2 pages of 2 KB each, and set NB_OF_VARIABLES to 240.When I tried saving 240...
I am working with the NUCLEO-N657X0-Q and I am looking for a reference project or a pointer to an example that implements USB Host Mass Storage Class (MSC).My Goal: I need to mount a USB memory stick to read test vectors, process them using the Corte...
Hello everyone,I’m working with an STM32F103RCT6 on a custom board, and I’m trying to use the built-in RTC using ST Low-Layer (LL) drivers.When I enter debug mode, the application gets stuck inside LL_RTC_Init(). It neither returns SUCCESS nor ERROR ...
Hi,I want to design a voice announcement system using the STM32F103C8T6.My requirement is to Load WAV audio files from an SD card and play them using the STM32, without using any external DAC.I would like guidance on how to start the project using ST...
