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...
Hello,I am trying to communicate with an SDI-12 sensor through my custom STM32L4 pcb. The communication that I am trying to achieve is from a 3.3V microcontroller. Thus, I used the SN74LVC1G240DBVT buffer to convert my UART to SDI-12 data one wire, a...
There have been a few posts on this forum with the same issue, but it seems the root cause is different to this post or (probably) this one.I am using an Stm32f446re Nucleo, and trying to output a waveform from dac2 using dma and tim6. What I have t...
Environment:STM32F407VGTX USB HID mouse, Full SpeedProblem:Hi, I’m using a STM32F407VGTX board. I send a USB remote wakeup signal to the host and then try to receive a resume signal from the host. The STM32 board can wake up the host (bringing it to ...
Hi everyone, I’m working on an audio project with an STM32H743ZIT6 and a MEMS microphone (MP34DT05-A). Audio is captured via DFSDM + DMA, and the DMA callback (HAL_DFSDM_FilterRegConvCpltCallback) fires reliably with fresh PCM audio samples. At the...
Hi, I want to get synchronized samples from 4 microphones connected via I2S2 and I2S3. First I set one as master and other as slave and just connect Clock and Word Select, but I have only 0 values on slave interface. Is it possible to do it this way?...
HiI'd like to do a memory-to-memory transfer, where I take a 8x12 px rectangle and copy it into a framebuffer. My display is 256x64px and it uses a grayscale 4 bpp format. My framebuffer size is 8192 bytes, and the rectangle that I need to copy is 48...
Hi, I would like to develop an application using ADC + TIMER + DMA. My base code doesn’t work, and I don’t understand why. To debug, I introduce the variable "toto". This value of this variable doesn't change. I use STM32CubeIDEv1.19.Best regardsThom...
Originally a comment on the "Using CAN (bxCAN) in Normal mode with STM32 microcontrollers (Part 2)" Knowledge Base article.Moved to the forum for better visibility & discussion.Hi,I just using STM32CubeIDE for 2 or 3 days. I am doing a test with a Nu...
Hi team, I am working with the STM32H7S78-DK board and implementing TLS 1.3 using WolfSSL on the client side. Project setup: Board: STM32H7S78-DK TLS library: WolfSSL (TLS 1.3 enabled) Network: TCP client socket Server: OpenSSL TLS 1.3 server Certifi...
I generated project with CubeIDE for Nucleo F411RE board with defaults.Now I want to create my own function void LED_blink(int blink_num);So, I created ledfunc.h and ledfunc.c files.This is my ledfunc.h file: #ifndef INC_LEDFUNC_H_ #define INC_LEDFUN...
