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...
Hi Guys, for an internship I am making a dual channel datalogger. So for that datalogger, I am using DS1338 RTC. Now instead of doing I2C normally, I am doing Bit-banging. I am using Nucleo-F030R8 board for my prototyping and I am using PA0(SDA) and ...
Possible Bug in HAL_SD_InitCard Hello wonderful STM community!I have identified a possible bug in the HAL Layer for the SDMMC peripheral. First time filing a bug report so please let me know if I miss anything import or if I'm completely wrongSystem ...
At STM32G431 Is it possible to make a (SPI daisy chain) shift register with one cyclic ringbuffer.With SPI peripheral as Full duplex Slave, with 2 DMA (RX TX) channels. "HAL_SPI_TransmitReceive_DMA(SPI_GetHandle(), ringbuffer, ringbuffer, SPI_size);...
HI,I am currently working on an Ethernet project using STM32F765IIT with the LwIP stack .I have configured the MAC and PHY (DP83848/DP83842) in MII mode, and link status is active.Now I want to verify Ethernet communication by implementing the ping (...
Hello, I have been following a few different Ethernet tutorials for my MCU (STM32H750VBT6TR) I have on a dedicated PCB. Thus far, I have been unable to get a simple ping test working. For reference, I am mostly using this tutorial in combination wi...
I'm learning about the I2C interface. The polling method works properly, but the interrupt method is not working correctly.I enabled I2C listen mode, but when I send the address on the I2C line, the address match callback is not triggered.
Hi, I am working on STM32G0c1RET6 board and i want to understand the working of low power timer (LPTIM) in stop mode.i am using the HAL_LPTIM_Counter_Start_IT(&hlptim1, 65534) to enable LPTIM1 and print a value in function void HAL_LPTIM_AutoReload...
DescriptionCurrently, in the HAL USB driver, the PCD_HandleTypeDef structure embeds the setup packet buffer directly:uint32_t Setup[12]; /*!< Setup packet buffer */ This design tightly couples the control structure (state, locks, callbacks) with a D...
Hello,On the STM32u5g9, using STM32CubeIDE 1.19.0 (CubeMX 6.15, just in case) with jpeg hardware .When debugging the Huffman tables, the rm-0456 gives the address boundaries for the AC0 and AC1 tables; 2 strictly non overlaping tables.In the SFRs men...
Is there an STMF4xx example project I can reference for using a virtual COM port to connect to FreeRTOS+CLI? I tried to do this myself by having the FreeRTOS+CLI function _write() call CDC_Transmit_FS() and by having CDC_Receive_FS() call a function ...
