when build my code over, start to run the code on my board, it occur a problem: 

Good afternoon,I am trying to encrypt some data using the AES peripheral and compare the results to the same operation in python and .NET. The cipher text output from the operation on the STM32 is different than that of the other two languages.The code I am testing is /** * @brief AES1 Initialization Function * @PAram None * @retval None */ static void MX_AES1_Init(void) { /* USER CODE BEGIN AES1_Init 0 */ uint8_t key[32] = {0}; uint8_t iv[12] = {0}; /* USER CODE END AES1_Init 0 */ /* USER CODE BEGIN AES1_Init 1 */ /* USER CODE END AES1_Init 1 */ hcryp1.Instance = AES1; hcryp1.Init.DataType = CRYP_DATATYPE_8B; hcryp1.Init.KeySize = CRYP_KEYSIZE_256B; hcryp1.Init.pKey = (uint32_t *)key; hcryp1.Init.pInitVect = (uint32_t *)iv; hcryp1.Init.Algorithm = CRYP_AES_GCM_GMAC; hcryp1.Init.Header = (uint32_t *)HeaderAES1; hcryp1.Init.HeaderSize = 1; hcryp1.Init.DataWidthUnit = CRYP_DATAWIDTHUNIT_BYTE; hcryp1.Init.KeyIVConfigSkip = CRYP_KEYIVCONFIG_ONCE; if (HAL_

Hi, I have create one adjustable multi vibrator circuit using 555 timer IC my aim is to achieve two things  1.Basically 555 timer IC output is Rectangular wave my aim is achieve ontime of one pulse 0-10us(Micro seconds) time delay  2.Another one is one pulse to another pulse generating time 10ms(Milli seconds ) So, How to achieve  this I am tried changes in resistor and capacitor value but  did not get proper time delay. I also Attached the circuit in below in document format .

Hi, When I connect a digital radio via the USB cable, Device Manager should show under USB: STM Device in DFU mode. However, it doesn't. Instead, I have an Other Devices: Digital Radio in USB mode, with a yellow triangle with black exclamation point. What do I need to do to get this to work?

工程师们您好，我是stm32的新手，我正在寻找一些关于STM32H747i-DISCO的教程和应用示例来帮助我学习它，但是我不知道如何烧录程序和点亮LCD屏幕，所以我想要一些简单的演示和导入程序教程。谢谢！

I use STM32F407 USB2.0 HS to send data periodically. The USB mode is high-speed mode. I configure the breakpoint IN transmission as the interrupt transmission mode. I use CDC_Transmit to send data. Each time it is judged that the last transmission is completed before sending data, and the time of interrupting the transmission is The interval is 1ms. I built a FIFO for the USB packet. The rate of USB packet generation is 2ms. I measured the time interval for each write and send data to USB and found that the maximum time interval will increase as the measurement time increases. Generally, the maximum interval for half an hour is 100ms, and for one hour it will be around 180ms. Our host computer is written in python, using the libusb library, and runs on the Windows 11 operating system. Can you guys see what the problem is?

Hello,I have a strange problem that I already lost a lot of hair over. I am using cubeIDE with an stlink v2 (STM32G441 with a blank C/C++ project and CMSIS). All run very well until today. So I am sure the code itself is ok.If I compile the project bin and elf files are generated. If I flash the generated files from the release folder with cubeProgrammer the program does not run. If I choose the run setting directly in cubeIDE the program runs fine. If I then read out the flash with cubeProgrammer the bin file is different from the one that was compiled in the release folder. So cubeIDE is running a different bin file than the one it generates in the release folder. How can that be? What am I missing here? This started out of nowhere. I can not recall changing anything other than the code itself. But of course I must have botched something up. I just don't know what could cause this.Edit: the generated bin file in the release folder is much shorter than the one I re

HI，All    I noticed that when we use BLE stack, we must set SYSCLK to 16MHz。When i set the SYSCLK upto 100MHz，the uart1 log will be garbled after call BleStack_Init which contained in st ble stack lib。I don't know if my discovery is correct。I don't understand why ST doesn't provide the source code for the Bluetooth protocol stack。 

HiI am having problems setting breakpoints when using the debugger in VS Code. I can step through manually but cannot seem to set breakpoints. Before starting to debug I can add a breakpoint at 50But when I run the code the breakpoint changes to a different line number outside of the loop line 54. Removed the target and reflashed in case the code is out of sync but do not understand. If I attempt to add a breakpoint in saysNew install (because 24.04 came out) but it did not work on the old install either.Thanks all - as ever

I have LL-API based UART/USART code which runs on an STM32U575 (tested on a NUCLEO-U575ZI-Q board), no problem (@ 115200).I would like to move this code to the LPUART (pins D0/D1, PG8/PG7, of the board).  However, I have failed; not even TX works (a probe connected to PG7/D1 shows low all the time when I transmit data on the LPUART).The changes I have made to my code are:Use the LL_LPUART_ functions instead of the LL_USART_ ones,Set AF8 for the pins,Use pin PG7 for TX (D1), PG8 for RX (D0),Call LL_APB3_GRP1_EnableClock().Select LL_RCC_LPUART1_CLKSOURCE_SYSCLK as the clock source for the LPUART (with LL_RCC_SetLPUARTClockSource()) so that it can achieve 115200.All configurations functions with a return value (e.g. LL_LPUART_Init()) returned success.  What have I missed?

Hello STMicroelectronics Community,I'm reaching out to you with a question regarding an SMD IC bearing the ST logo. I am in search of the datasheet for the IC labeled CCIC1I in the TSSOP28 package. Unfortunately, I couldn't find any information about this IC on the ST.com homepage. Where else could I look? Is the datasheet possibly restricted? Or do I need to contact a specific address?I require this data for repairing a projector and would greatly appreciate any assistance.Thank you in advance for your support!Best regards,Sven

Hi ST team,I have design the 10V isolated power supply design using viper222LSTR IC having universal input AC supply. Schematic of the circuit is attached here.When i am increasing the input voltage, voltage across the capacitor C7 maintain constant of 10V, while voltage across capacitor C12 is in increases, winding of the transformer, W3= W2= 30 turns, are same and W1= 180 turns. So why?1.  My voltage across the C12 is incases with increasing the input voltage.2. With increasing the dummy load (i.e. R8= 1K) then viper222 get on & off frequently.I have required constant 10V across C12 in isolated manner while increasing the input voltage ( I am extracted from C12 because of need of isolated power supply and and i want to avoid use of optocoupler in the circuit)       How i can fixed it, please help use.Thanks and Regards,Pemendra Pardhi  

Hi All,I found several topics with controversial information about what is this file used for?Like this:https://community.st.com/t5/stm32cubemx-mcus/what-is-the-mxproject-used-for/m-p/584042 I see in my file several sections [PreviousLibFiles][PreviousUsedKeilFiles][PreviousGenFiles] I don't see any critical information but not sure should I add it to commit or not?Thanks

Hi, Thew board was working fine until i tried to get serial working over virtual COM. I'm not sure what ive done but now im receiving this messageError in final launch sequence: Failed to execute MI command: load C:\\Users\\Ki\\STM32CubeIDE\\workspace_H503\\blink\\Debug\\blink.elf Error message from debugger back end: Error finishing flash operationIs there a way to reset the board? or have I bricked it. It still talks to the link utility in the IDE and says it needed an update which completed successfully.Sorry Im a bit lost and would appreciate some guidance. I can provide more info if neededThanks in advance

Hi guys,I want to know whether the device meets the 100Mbps full duplex need how to test?My own test is as follows:The device ip is 192.168.1.10, pc ip is 192.168.1.135.(The ip of pc is different in wireshark(135) and test software(25), because it is not the same pc and same test, just for your information)First of all, when connecting the device to PC via RJ45, the Ethernet link shows 100Mbps. I used the speed test software on PC, when sending arp, icmp, tcp, udp packets to the device at the same time, the device won't reply to some of the packets, especially not to ICMP packets.In this case, is the device considered to meet the 100 megabit full duplex? Or do all requests have to be replied by the device. 

Hello STM32 community,I've been examining the lsm303agr.h file from STMicroelectronics for the LSM303AGR accelerometer, and I came across something puzzling in line 197. In the code, it defines LSM303AGR_ACC_SENSITIVITY_2G as ((uint8_t)1), but according to the LSM303AGR datasheet, the linear acceleration sensitivity at ±2 g in normal mode is 3.9mg/LSB.Could someone help me understand why there's a discrepancy between the code definition and the datasheet specifications? I'm curious about the reasoning behind this difference and how it might impact the usage of the accelerometer in my project.Thank you in advance for any insights you can provide!

Hi, I am unable to interface with a sensor over RS485. I have a uart->RS485 converter hooked up to pins for USART1 (Tx on PD8, Rx on PD9) on a Nucleo-F439ZI.I also have a USBtoRS485 converter with which i'm able to communicate to the sensor fine. I have a scope connected onto the B- line and can compare the data.The sensor prescribes the following UART settings:Data bits: 8Number of stop bits: 1 bitParity: evenBaud rate (bps): 57600 (factory setting)and I have set USART1 t initialize with the following settings:huart1.Instance = USART1;huart1.Init.BaudRate = 57600;huart1.Init.WordLength = UART_WORDLENGTH_8B;huart1.Init.StopBits = UART_STOPBITS_1;huart1.Init.Parity = UART_PARITY_EVEN;huart1.Init.Mode = UART_MODE_TX_RX;huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;huart1.Init.OverSampling = UART_OVERSAMPLING_16; An image looks as can be seen in the attached scope3.jpg picture where RefA (grey) is the recorded (working) signal from the USBtoRS485 converter and CH1 (yellow) is t

When I hit Debug. System stops at first line of main() as intended. However no matter how I setup any breakpoints on the rest code, and hit Resume(F8) button. The code never stops on those breakpoint. even though I am 100% sure those breakpointed line code got run already. and if I hit suspend. the code stops normally. Also step into or over works normally. ( I am sure that the number of breakpoints I setup is less than 4) I checked log file of st link GDB server. I did not see any breakpoint setting command sent to the debugger via the SWD. Is this a software bug of CubeIDE? I saw some youtube video. it shows the breakpoint works fine. Could anyone give me some hint. I stuck on this issue for two days. :(

Im currently working on a custom PCB with cc1120 as transceiver and stm32f446RET6 as MCU. I integrate the cc1120 library from IT's library. The device uses SPI as serial communication. Here is the communication example in given datasheet. With this information i configured the SPI settings as:after that i use HAL_SPI_TransmitRecieve( ) function as my comm func. in driver. But im not gonna share the complex library instead i will demonstrate the situation. My CS pin and cc1120 reset pin is logic HIGH in idle by software.txdata[0] = 0x30; HAL_GPIO_WritePin(SPI1_CS_GPIO_Port, SPI1_CS_Pin, 0); HAL_SPI_TransmitReceive(&hspi1, txdata, rxdata, 1, 500); HAL_GPIO_WritePin(SPI1_CS_GPIO_Port, SPI1_CS_Pin, 1); /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { txdata[0] = 0x2F; HAL_GPIO_WritePin(SPI1_CS_GPIO_Port, SPI1_CS_Pin, 0); HAL_SPI_TransmitReceive(&hspi1, txdata, rxdata, 1, 500); HAL_GPIO_WritePin(SPI1_CS_GPIO_Port, SPI1_CS_Pin, 1); HAL_D

HAL timebase set to use TIM6. ThreadX uses SysTick.My code is minimalistic for the test-project when debugging this issue. ThreadX is set up to have 1000 ticks/second as opposed to the default 100 ticks/second.I have one thread printing out HAL_GetTick() and _tx_time_get() after a tx_delay of 1000 milliseconds.HAL_GetTick as we all know returns uwTick, which gets incremented by the TIM6 interrupt callback.ThreadX returns the correct time, while GetTick() returns a value that gets incremented by about 15 for every 1000 ms. My only explanation for this is that ThreadX disables the interrupt that calls the TIM6 IncTick function while it does scheduling work in the background, but I have a hard time believing this as I can't find anyone else facing the same issue online.

I am trying to get a SPI port up and running on an STM32H745BI chip but after configuring the port and starting the transmission I never see any signals on the pins and the port never gets an End Of Transmission (EOT) high signal. Startup code is listed below, it hangs while waiting for EOT. Relevant register values are in the attached image. Any ideas on why this code doesn't work?
