Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
Hi,I have a background in electrical engineering but am a complete beginner with embedded engineering. I've bought two nucleo f767zi boards with the goal to send information between them using Ethernet with the built in rj45 port. My goal right now i...
Hi there.As usual, I'm there with a new issue... :grinning_face_with_sweat:Developing a custom Bootloader, I'm trying to disable both Instruction and Data chaches.As I read on the ST AN4839, before deactivating the DCache, I would also Clean it.No pr...
Today I started to implement DMA for the SDMMC peripheral, and it worked for the most part, but when I got around to doing some sector writes, I started to get CRC-16 mismatches. This was a relatively simple fix, as I was enabling the Data Path State...
In the ethernetif.c file,typedef enum{RX_ALLOC_OK = 0x00,RX_ALLOC_ERROR = 0x01} RxAllocStatusTypeDef; // Here, RxAllocStatusTypeDef type is not used.It says that RxAllocStatusTypeDef is not used, which violates misra-c:2012 2.3.Inferentially, this wo...
Hello,I'm having some issue going from my user code running azure RTOS to the bootloader. I'm using a STM32U599The code I'm using is the following, you can find online: void JumpToBootloader(void){uint32_t i=0;void (*SysMemBootJump)(void);/* Disable ...
I'm using an STM32 H7 and CubeIDE, As the title states, When placing a breakpoint at HAL_UART_TxHalfCpltCallback, it is triggered.But when placing it at HAL_UART_TxCpltCallback it is never triggered, it used to work, but I don't know where it went wr...
Today I decided to improve the performance of my USB driver by transferring multiple IN packets at a time, instead of one at a time. This in theory would be relatively easy, as I can just configure the IN endpoint's TX-FIFO to have a larger allocatio...
Hello I am working on the Free RTOS code that I am trying to send the data on the server using Free RTOS but I am not able to send data on the server I am using some dummy data and GPS for location +STM32F411ceu6a+EC200U GNSS. But my RTOS task is not...
Hi, i'm using my Nucleo STM32F401RE as a HID Device for a MIDI Keyboard projectI have configured the following:Connectivity --> USB_OTG_FS --> Device OnlyMiddleware --> USB_DEVICE --> Human Interface DeviceI followed a video tutorial to configure the...
Hello everyoneI do not understand how to use the STACK_SMBUS_ExecuteCommand callback function provided by the SMBUS stack (See picture below). The function is called either in receiving data or transmitting data (from the device point of view). Due t...
