Hello,I am utilizing a FreeRTOS system on the STM32H725AGI6 in my software with two purposes:- Run a task that handles the TouchGFX process to operate an LCD display- Run a task that handles a BLE process (Which utilizes theBlueNRG-M0A)I have tested both processes separately and both work as I intend them to.  I created the two tasks with the FreeRTOS system and observed that:- If I comment out the creation of the TouchGFX task in the main.c, the BLE portion works as intended- If I comment out the creation of the BLE Task, in the main.c, the TouchGFX portion works as intended- If I run both tasks at the same time, the TouchGFX portion works as intended, the BLE initialization code is run, but the repeated process (MX_BlueNRG_MS_Process()) is never called.I've included the task initialization and process for both below. Additionally, I've attached my CubeMX configuration for the FreeRTOS system. I have tried to do the following:- Increase the cheap size to 35000

I am trying to bring up the MX25UM51245G NOR Flash connected to OctoSPI 1 on a STM32U5xx development board. I have implemented most of the actions specified in AN5050 to set up this NOR Flash.Since my use case does NOT require the ability to have the MCU write to the flash, I have only implemented the read mode of the memory mapped interactions.I have generated code using CubeMX and have set up the memory component as follows:    1. HCLK is 120Mhz.    2. Single Data Rate (expect the OctoSPI to run at 60Mhz).    3. OctoSPI clock prescaler set to '1' ==> expect this to generate a 60Mhz clock to the OctoSPI.When I run the firmware I see that the  MCU has no issues accessing the OctoSpi and the OctoSpiManager on the MCU. I also do not see any 'obvious'  errors when the MCU interacts with the memory's SPI component in 'indirect' or 'auto polling' mode.Then I enable the readonly memory mapped mode (based on example in AN5050) but the

Hi,I have an STM32L0538 discovery board and I'm trying the Demo example. The problem is that it does not work. When I flash the board it changes the e-ink display like this:Also when I touch the bottom bar it does nothing. The revision of the board is Rev-B03.I use the example from the STM32CubeIDE:I need to change something in the project??? Because seems like it works partially.Thanks in advance!

Hi,I'm using STM32G431RB on the NUCLEO-G431RB developement board.I want to generate a signal from an array each time an external trigger is received.The signal is sampled with the TIMER6 trigger, which is rised every 1us. (MCU clock is 170MHz, TIMER6 PSC is 0 and ARR is 170-1).TIMER6 configurationThe DMA is set to normal mode (because I want to generate a signal only when the trigger comes, and not continuously)DAC DMA configuration The DAC is configured like this:DAC configuration I'm calling the HAL_DAC_Start_DMA function each time the external trigger rises, but, even if the trigger is repeated each 1ms, the signal is generated each 2ms. The minimum interval between a signal generation and another one is 2ms and basically I need to reduce it as much as possible.Signal Here the trigger is faster than 2ms but the signal is generated each 2ms The code:/* Private variables ---------------------------------------------------------*/DAC_HandleTypeDef hdac1;DM

Hi,I am trying to use 3 ADCs on STM32F407 with 'Triple regular simultaneous model only'. This option is avaliable in CubeMX configuration, but I can not get it working in the code. I would like to sample 3 channels using the 3 ADCs at the same time. Can you please let me know how to set up this correctly? Which API shall I use?

I am using the STM32H745 series MCU, with the latest (or very recent, at least) version of CUBE IDE.I'm having difficulty getting past errors for including CDT list, map etcIE #include <list> ... doesn't include C++ CDT list and results in errorsAre there any compiler settings, to force inclusion of the full C++ CDT?Or any middleware/ 3rd party STM32 forks, that I can use?

Hi Team​Is it necessary to add a 1.5k pull-up resistor to D+ or D- when using USB VCP at full speed mode with STM32F405 MCU?The port of the MCU be automatically pulled up when the USB of the MCU is set?Please let me know if there any document for recommended circuits.

Hello,I am new to this cpu and experimenting with RTC wakeup using 32kHz LSE. I am usingthis code for the wakeup: void HAL_RTCEx_WakeUpTimerEventCallback(RTC_HandleTypeDef *hrtc){SystemClock_Config();HAL_ResumeTick();...} // In while(1)HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 0x4E30, RTC_WAKEUPCLOCK_RTCCLK_DIV16, 0);HAL_SuspendTick();HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);... I removed the SetWakeUpTimer() function from MX_RTC_INIT().It was working fine. I tweaked the MCU clock and generated the code with CubeIDE. I am not sure what went wrong but now its executing the callback (instead every 10s) instantly as fast as it can. I reverted everything i know about but still the same. Hope someone can give me a hint on what configurating i need to fix to make it work again.

Hello there!I've been tinkering around with the STM32H5 and recently I've managed to setup the STM32H563 with SPI and DMA.I'm now trying to understand what is the limit of the burst (either source or destination).  I'm using the DMA channel 4 (with a FIFO of 32 bytes) to receive the data coming from the SPI peripheral. Since this is my first time looking into the DMA, I thought the limit of data I could route through DMA was the FIFO size of 32 bytes. However, when I look into the RM section 16.4.10 about the GPDMA burst, I can see it supports up to 4 bytes * 64 ! In my understanding, this would mean DMA could route 256 bytes max at once. Am I mixing stuff up here?When I try to read the max amount of bytes (4*64) the system doesn't work. It only works when the Size argument of `HAL_SPI_Receive_DMA` is less than the `DestBurstLength` setup inside the `HAL_SPI_MspInit`.Here's the DMA configuration inside the HAL_SPI_MspInit: handle_GPDMA1_Channel4.Instance = GPDMA1_Ch

Hi there!I was trying to emulate eeprom using flash memory. I am using Nucleo-F030R8 board.

I am suspecting that the ODR setting in my application is not correct. I want to be using 25Hz so according to the datasheet I would set register address 39h to 48h. 25Hz equals 001 which would give 01001000 = 48h.But all examples and also the Unico tool outputs 4Bh instead of 48h. Am I missing something or should the last two LSB bits always be 1 instead of 0?

Hello everyone,I would be mentioned this topic here which is the same.I am using KeyboardWidget of TouchGFX in my project and need to print the value from keyboard.getBuffer() into a const char to draw it again in QRCode.I have tried all the ways but no result and got some errors.char QRBuffer[20]; void MainView::CreateClicked() { // Show the entered text in the text box on the display Unicode::strncpy(textAreaQRBuffer, keyboard.getBuffer(), TEXTAREAQR_SIZE); // Copy the entered text into the char string to drawing QRCode Unicode::snprintf(QRBuffer, sizeof(QRBuffer), "%d", textAreaQRBuffer); // Drawing the QRCode CreateQR(); }I have used strncpy but also no way! I have tried to casting the buffer value like this but also not working:char* QRBuffer = (char*)textAreaQRBuffer;Any suggestions?Thanks, Mahdi

 i am using NUCLEO-F410RB boardi followed the simple exti tutorial try to print "button pressed" to uart when the corresponding button is pressedlike most of the tutorial setting : interrupt rising edge . no pull up and pull down , one side of button  is the certain pin and the other side is connect to the board 3.3V pin and insert code like this void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if(GPIO_Pin == GPIO_PIN_14){ printf("button pressed"); } } i have tried several exti gate. they have the same problemeven i just plug a wire to the certain pin , the other end of wire has not connected anything yetthe uart would display a tons of 'button pressed' which means the exti was triggered multiple timeit is kind of weird do you guys have encountered this problem before?  

The datasheet for the LD1086 specifies that I should use a 10 uF capacitor to filter the input/output of the device. The datasheet schematic for a typical application shows polarized filter caps. But the datasheet doesn't specify what type of capacitor I should use (polarized aluminum, polarized tantalum like LDO linear regulators, etc.).Should I use polarized tantalum caps? Or will even unpolarized ceramic caps work, as long as they're 10 uF? Thanks!

Hello everyone,I've been diving into the world of ESP32s and Arduinos for approximately 2 years now. My current project focuses on GNSS tracking combined with radio transmission. Initially, I was inclined towards using the ESP32-S3, however, as the project evolved, I find myself inclined to seek a more robust solution with a more powerful MCU, hence my interest in the STM family.Here's where I'm hitting a roadblock:Given the significant time and effort I've already invested in developing code for the ESP32, I'm hesitant about starting from scratch. So, my question is:How seamless is the transition from the Arduino-like programming in C++ (as I've been doing with the ESP32) to programming an STM32?Can I expect to use most of the libraries created for Arduino? For instance, I'm utilizing Sparkfun's Arduino GNSS library for tracking. Is there a possibility that I can reuse a significant portion of the existing code?Any insights or experiences you could share would be immensely helpful. Lo

I am trying to read and write to the MT25TL01G on the STM32H747I-DISCO board via the QSPI interface during runtime. I followed https://community.st.com/t5/stm32-mcus/how-to-add-a-bsp-to-an-stm32cubeide-project/ta-p/49812 to add the BSP to my project, using the QSPI files instead of the LCD files, and using the MT25TL01G component instead of the devices specified in that post. The program successfully compiles and runs, but data is not successfully written/read from the mt25.The code I have written is below, and should function as a basic test of QSPI read/write functionality.The program loops as intended, and does not get stuck anywhere. However, the result buffer always remains filled with 0s and never matches the data buffer as intended.Using ST-Link, I have confirmed that the program successfully fills the address specified with 0s, but does not successfully write data values.Please let me know what I'm missing :)My init function:/*** @brief QUADSPI Initialization Function

Here is a code of HAL_I2SEx_TransmitReceive() function on F4 series reduced for the sake of example: HAL_StatusTypeDef HAL_I2SEx_TransmitReceive(I2S_HandleTypeDef *hi2s, uint16_t *pTxData, uint16_t *pRxData, uint16_t Size, uint32_t Timeout) { // ... HAL_StatusTypeDef errorcode = HAL_OK; if (hi2s->State != HAL_I2S_STATE_READY) { errorcode = HAL_BUSY; goto error; } // ... /* Process Locked */ __HAL_LOCK(hi2s); // ... error : hi2s->State = HAL_I2S_STATE_READY; __HAL_UNLOCK(hi2s); return errorcode; } The if block and it's goto is completely broken.If the state is not HAL_I2S_STATE_READY, the code just sets it to that state and does the __HAL_UNLOCK(), damaging the current actual driver state.The __HAL_UNLOCK() should not be executed without the corresponding __HAL_LOCK().The state variables cannot be accessed outside of the critical section, because it breaks the whole logic behind the critical section.Just a quick search reveals, that, fo
