Hi everyone, I have a p-nucleo lorawan 3 kit with a nucleo-l073rz board and a lorawan ns1 lora board. ​I'm trying to setup the AT master example from I-NUCLEO-LRWAN addon using keil uvision. I uploaded the program and activated the CMD_DEBUG but I don't get any output on TeraTerm. ​I firstly tried to follow the instructions on https://community.st.com/s/question/0D53W00000rauT3SAI/cant-make-at-master-application-to-work-on-nucleolrwan1nucleol073rz-pair but it seems that everything as been solved since last version. ​I also tried to use an arduino instead of a nucleo board to talk to the lora board directly but without any success... ​Has anyone faced the same problem? Thanks!

Hello !I am currently working with a STM32F407VGT7 and I have troubles uploading some code in it. I did the simplest possible code with STM32CubeIDE : RCC configuration and some dummy operations in main while loop. My problem is that after uploading code (with debug feature), starting it and pausing it a little while after (like 3 seconds or so), I got this error : "Break at address "0x1fff36aa" with no debug information available, or outside of program code."I have no idea what is causing this error. But seeing from STM32F407 datasheet that 0x1fff36aa is mapped in "System Memory + OPT" area, I guess this is not good...I noticed that this bug doesn't occur if interrupts are disabled. Please find my code bellow.Any idea of what could be causing this issue and how I could solve it ?Thanks.int main(void) { /* USER CODE BEGIN 1 */   /* USER CODE END 1 */   /* MCU Configuration--------------------------------------------------------*/   /* Reset of all peripherals, Initia

Hi,I'm working on the two MCU's STM32WLE5C8U6 & STM32WLE4CCU6 and I need to know the UID in order to indentify each of the products.In the doc it's written that both have UID but there is no address to read them.What I'm missing ?Best regards,

STM32G474RET / FDCAN1 When I create with a STM32 Project, there will be creatied different startup files (startup_stm32g474retx.s) depending wether I selectTarget Projekt Type "STM32Cube" or "empty"!- STM32Cube => startup_stm32g474retx.s with Copyright (c) 2019- empty    => startup_stm32g474retx.s with Copyright (c) 2020This files are differ from eahc other, especially some names of interrupt vectors differ - furthermore more odrder of FDCAN1 interrupt vecotrs differ (0 <==> 1) !!!I've created a STM32 Project with an empty Target Projekt Type and use therefore the newer startup file.When I let run my small programm and "Suspend" it, after a CAN message has been transmitted (it has been received by PCAN-View on the PC), it seems, the CPU loops in the Default_Handler.When I change order of interrupt vectors from  .word   fdcan1_intr1_it_IRQHandler           /* FDCAN1 inter

Hi,virtual void setFrameBufferStartAddresses(void* frameBuffer, void* doubleBuffer, void* animationStorage)1, Parameters frameBuffer and doubleBuffer can generated by CubeMX, animationStorage parameters can also be generated by CubeMX ? 2, I don't use the animationStorage parameter and the animation of the Icon will play normally, when will the animationStorage buffer be used ?3, How to determine the size of parameter animationStorage, does it have to be equal to the frame cache size ?

Hi, Can we use ST25RU3993 Eval kit in Device mode directly(instead of Host driven), without using the GUI application.Need to use it directly without using GUI Application for making configuration for detecting the TAGs. Please let me know if such setting are present or not in the available firmware SDK or any change are required to make it working.All the supports are highly appreciated.Thanks SS

Hi,I have seen this some time ago in another thread: https://community.st.com/s/question/0D53W000005771OSAQ/stm32h7xx-spi-tx-with-dma-halspitxcpltcallback-is-called-only-if-dma-is-configured-in-circular-modeI am kind of repeating the questions in that last thread, because I did not see any final answer.Still in FW H7 v1.9.0 the problem persists. In stm32h7xx_hal_spi.c using the DMA the TxCpltCallback is never called if not in circular mode. static void SPI_DMATransmitCplt(DMA_HandleTypeDef *hdma) { SPI_HandleTypeDef *hspi = (SPI_HandleTypeDef *)((DMA_HandleTypeDef *)hdma)->Parent;   if (hspi->State != HAL_SPI_STATE_ABORT) { if (hspi->hdmatx->Init.Mode == DMA_CIRCULAR) { #if (USE_HAL_SPI_REGISTER_CALLBACKS == 1UL) hspi->TxCpltCallback(hspi); #else HAL_SPI_TxCpltCallback(hspi); #endif /* USE_HAL_SPI_REGISTER_CALLBACKS */ } else { /* Enable EOT interrupt */ __HAL_SPI_ENABLE_IT(hspi, SPI_IT_EOT); } } }What is the reason for hiding that TxCpltCallback?

Hello Everyone,I am working on a project in which we load hex or bin file in USB pendrive and stm32F7 will read this file over USB_FS using Fatfs. Then it will program it self using same hex file(IAP from USB pendrive ). if i am using only internal flash every thing is fine no doubt about hex or bin file, But if i will also use external qspi flash then IDE like cube ide or Keil are generating single hex or bin file for both Memory. Now my question is that how to identifies that which data in file is for internal flash and which one is for external one?Thanks

At the moment I have ST MV C737, how I understand it is zener diode, but no info in internet and here. Anyone can help to identify?

Thank you for helping.I want to move to a certain screen when the timer times out.What kind of implementation should I do?Thank you.

Hi, I recently read the AN5165——Development of RF hardware using STM32WB microcontrollers，and the page25~page27 show the STM32WB55's reference design.But I didn't find the file on the offical website.Could you please share the files named:MB1427A---UFQFPN48MB1422A---VFQFPN68MB1547B---UFBGA129MB1425A---WLCSP100Thank you very much.

Hi, everyone.I have a board with STM32F215 uC and I want to create a Data Logger on FreeRTOS.I've been reading about these problems and I don't find what's going on.I modified the task's stack on the FR configuration, I made sure that timebase source it's different from systick. I use a Mutex on the SD_task, but nothing works... I'm wondering if someone here can provide me any simple example. I'm desperate.Peripheral for SD is SPI.Thanks a lot for any flash of illumination.Sorry for my bad english.

I was looking over the example projects that come with CryptoLib v4.0 in the package en.STM32CubeExpansion_Crypto_v4.0.1 for examples related to X.509 certificate handling and was not able to find anything in that regard. I wanted to confirm whether or not CryptoLib supports X.509 certificates? It does not seem to do so. What is the recommended option for incorporating X.509 functions on STM32? Thanks!

In this way, error never occurs leading to wrong baudrates. if (pclk != 0U) { /* USARTDIV must be greater than or equal to 0d16 */ usartdiv = (uint16_t)(UART_DIV_SAMPLING16(pclk, huart->Init.BaudRate, huart->Init.ClockPrescaler)); if ((usartdiv >= UART_BRR_MIN) && (usartdiv <= UART_BRR_MAX)) { huart->Instance->BRR = usartdiv; } else { ret = HAL_ERROR; } }Cast to (uint16_t) should be removed.

I am trying to establish a hardware-in-the-loop setup with a STM32F429I-DISC1 with Waijung blockset. But I have a problem trying to establish UART communication. I dont receive any data coming out of the microcontroller with this method.The host and the target simulink simulations are given in the figure below. I have installed the waijung_18.11a blockset.Firstly, I wanted to try setup the UART Setup-block with certain settings, but stumbled on the following: I can't set it to UART1 and get the following error given in the figure below. The options to set the Tx pin and the Rx pin are also limited. So I tried to establish the communication with USART3, PD8 and PD9 by first building the target and running the host. And got the following error given in the figure below. According to the datasheet this pins can be used for UART: https://www.st.com/resource/en/datasheet/dm00071990.pdf . Before I used the Waijung blockset I have established processor-in-the-loop with STM32 MAT/Target blocks

I have what I am sure to most a simple C question (I'm a hardware guy at this end).....For brevity I would like to take the following statements and combine them using 1 for loop but don't know the semantics on how to do this....I am using the HAL library with CubeMX: TIM2->CCR1 = pwmPulse[speed] - HAPTIC_PW; TIM2->CCR2 = pwmPulse[speed] - HAPTIC_PW; TIM2->CCR3 = pwmPulse[speed] - HAPTIC_PW; TIM2->CCR4 = pwmPulse[speed] - HAPTIC_PW; Below is a FAILED attempt: for (uint8_t i = 0; i < 4; i++) { TIM2->(CCR1 + i) = pwmPulse[speed] - HAPTIC_PW; }Thanks for the help

Hi,We have an ST25DV04K NFC tag which is being used to communicate to a host microcontroller from a mobile app and we're having trouble with FTM after booting up the host device from the app.We're starting up the host from this app by pulsing the GPO line. Unfortunately, the maximum interrupt time is too short so we're generating a pulse with the Manage GPO command; set, wait 100ms, reset. This works great.Once the device boots up, it then configures the tag to disallow RF from controlling the GPO with the Manage GPO command (by setting RF_USER_EN to 0 in GPO register).Then, we need to send some data to the host via FTM. So we enable the mailbox and write our data. On the host side, we see the interrupt, check the IT_STS_Dyn register for RF_PUT_MSG, then read the data, calculate the CRC, then write that back to the mailbox.This is where there's an issue. The mobile app is now polling the MB_CTRL_Dyn register for HOST_PUT_MSG. However, that never happens. Even stranger, if we move the p
