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...
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...
I can transmit data in this code, but I cannot receive data with an interrupt. Can you help me?Code:#include "main.h"#include "kibar_nextion.h"#include <string.h> UART_HandleTypeDef huart4;UART_HandleTypeDef huart3; uint8_t main_buffer[13];uint8_t pu...
Hi everyoneI have some issues using the X-CUBE SMBUS stack from ST.Issue 1:I have an issue with the alert response process. I am using 2 WB55 NUCLEO's. One is defined as host, the other is a device. Now when the device pulls alert signal low the mast...
Hello,I have a custom pcb with STM32H747XI and a DSI LCD. Everything is on M7 with PWR_DIRECT_SMPS_SUPPLY.The issue that I am facing is that I can't write any data on lanes. Both Positive and Negative are on 1.44v constantly.I tried to be as close as...
1. CubeMX only allows HAL or LL for SPI and other peripherals. STM32C031C6 itself provides the good SPI clock rate. SPI LL API function only allows two-byte R/W.. The slave STPM34 Meter IC requires 4-Byte SPI R/W. So we have to choose HAL SPI API ...
I am new to embedded programming and very recently got started with programming the STM32F407G Disc-1 board with STM32CubeIDE(1.12.0).I typical register level program for LED blinking:Blinking the on-board LED - LD4. int main(void){uint32_t *clk_reg ...
I use NUCLEO-F722ZE and STM32CubeIDE.When I set SDMMC1 to SD 4bits wide bus, the RCC shows a warning “partly disabled conflict with : SDMMC1 : SD 4bits wide bus”. At this time, when I wrote a program on the board and operated it, “FR_DISK_ERR” occurr...
