STM32 MCUs

Hi, We are using STM32u585 device on our board, we want to use a part of internal flash memory for permanent data storage.  Please clarify the following. 1)is it possible to use internal flash access using LevleX (non RTOS)?2)is there any reference available?Thanks in advanceG.Vaikundam 

Hello everyone,I am working on a BLDC motor and have implemented Field-Oriented Control (FOC) on an STM32f103c86  microcontroller. For rotor angle estimation, I am using a Luenberger State Observer and calculating the rotor angle using a Lookup Table (LUT).Issue:I am not getting the expected rotor angle waveform.The estimated angle does not match the expected smooth transition.The waveform appears distorted or has unexpected behavior.Details of My Implementation:MCU: STM32F103 (or mention your exact MCU)FOC Control Method: Using SVPWMAngle Calculation: Using LUTObserver Type: Luenberger State ObserverTroubleshooting

Hi, I am facing an issue on STM32F469 where UART is not initialized with DMA properly if I dont add  some delay around 300ms as show in my initialization. /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_ADC3_Init(); MX_I2C1_Init(); MX_RTC_Init(); MX_SPI2_Init(); MX_TIM1_Init(); MX_TIM2_Init(); MX_TIM5_Init(); MX_SPI3_Init(); MX_UART8_Init(); //MX_USART2_UART_Init(); MX_RNG_Init(); MX_USB_DEVICE_Init(); /* USER CODE BEGIN 2 */ HAL_GPIO_WritePin(EN_3V3_SW_GPIO_Port, EN_3V3_SW_Pin, GPIO_PIN_SET); HAL_Delay(300); Serial_Receive();This serial receive function

STM32L432KC Nucleo GPIOA resets to 0xABFF FFEF instead of 0xABFF FFFFI can't write 0 to $4800 0000 [GPIOA_MODER]Ports B and C behave as expected: the correct reset values and it is possible to write 0x0000 0000 to B and C.How can I resolve this?Or has GPIOA died?Firmware version: V2J45M31ST-LINK/V2-1

Hello!I wonder if anyone has had experience making a dimmer on an STM32F746? For example, want the display to dim after 1 minute of being idle. It should remain bright enough to read, then return to full brightness on touch.I saw some posts that PWM should be used with a Timer pin, but this doesn't appear to be an option on the STM32F746?Thanks,the Windmill

Hello,I created a timer for a display using two text areas. One is a text area with a single wildcard (i.e. minutes), and another is a text area with two wildcards (i.e. seconds). It runs fine for ~9 minutes and 4 seconds but then suddenly the text area with two wildcard randomly generates a ? on the second wildcard, and this occurs on both the simulation and on the hardware that I am running. The typography has the 0-9 wildcard ranges, for all font sizes used. There are rare occasions when the question mark (?) goes away, but I do not know at what time that occurs. Any help is greatly appreciated.

Respected Members,We are using STM32Cube Package 1.16.0 and STM32CubeIDE v1.12.1. We have 10,000 devices in market with BLE stack v1.16.0 and FUS v1.2.0 (STM32WB5MMG). We encountered a BLE related disconnection bug that was resolved when we switch to BLE stack v1.21.0 so now the idea is to wirelessly OTA BLE stack of CM0+ and firmware binary of CM4+.But the problem is that whenever I make a call to FUS using SHCI_C2_FUS_GetState(NULL), it is blocked and keeps waiting on shci_send( SHCI_OPCODE_C2_FUS_GET_STATE, 0, 0, p_rsp ); This call never returns if I check with debugger (STLINK-V3 using IDE attached).Now, if I manually start FUS from CubeProgrammer, then re-run the firmware, FUS get state works but I cannot do this on working devices deployed in the field. If BLE stack is running, I cannot seem to get this call SHCI_C2_FUS_GetState(NULL) to work.The startup script and linker script is attached as well along with

Hi everyone, after I've configured TouchGFX, the program needs to be manually run in Keil's debug environment to execute. Why is that?My ICNA3306_DrawBlock data transfer did not use DMA. 

Hi,what is the best way (excluding asking them to use TouchGFX) to show a preview of a touchGFX project - with just button functionality to navigate between screens - to a someone?Is there perhaps a viewer for Window or can a project be compiled and sent as .EXE?If not, what is the best way to send someone an interactive TouchGFX UI project (again, all I need is the navigation between screens through the buttons in the UI)?Thank you

I have three buttons who's wild card text I change programatically. When I do so, the alignment of the text changes from centre-aligned to left-aligned.Before: After:A) How do I prevent that from happening?OR

Hi there,I'm new to STM32 and was successful to setup a 800x480 LCD with a STM32H743 and SDRAM as Framebuffer.Now I'm stuck with desiging the GUI with TouchGFX. I would like to add the Slide Menu Option to my screen, however when I press on the assigned button nothing happens in the simulator. I looked at the Slide Menu example but I can't see a difference to my setup. Could someone also have a look at my configuration?  

Hi all,I'm working with an STM32-based motor control setup ( The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller), and I have a physical PMSM motor that I want to use with FOC (Field Oriented Control).I need help figuring out the following motor parameters:Parameters I want to find:Stator resistance (Rs in Ohms) Stator inductance (Ls in mH) Back-EMF constant (in Vrms/kRPM or Vpeak/kRPM)Maximum mechanical RPM What I have: Physical motor only and basic data (no datasheet)PMSM motor Volt -24Current -4.3 ampPower -105WRPM - 500 Hz- 83.3 HzPole Pair -10Torque -2.0 NmCan measure with multimeter, oscilloscope, etc.Using STM32 Nucleo-

Hello community ,I am newby trying to do a small project  with STM nucleoh563zi  and stumble upon following brickwall .I need to interface an Incremental encoder that produces 1000pulses per rotation and simply print it to com port  and i searched  as many resources as i could and all of them are pointing / deal with encoders with less pulses such as ky-040  and i tried to replicate and failed all the time .could you please help me by suggesting me any  resource that can help an absolute beginner to learn to work with encoders with high number of pulses per rotation , any road map or suggestion , or simply a step by step guide would help me out a lot 

OK, this is perhaps a fairly stupid question but I do not get it.I have an analogue voltage in range -5V..+5V and wantto measure it with the ADC of an STM32F446. The ADC-input works in range 0..3.3V.I have the feeling I can do that with a simple, resistor-based voltage divider that pulls down the 10V effective of the input value to the 3.3V the ADC expects.But...how has ti voltage divider to look like when going with +-5V, means when it starts at -5V?

Hello@STTwo-32 @Remi QUINTIN , We are using STM32WB55RG MCU for our development. From the examples I came to know that the BLE device  initially starts advertising as peripheral and the mobile device as central will be able to scan the device and initiate the connection. Once connected the device advertising is stopped. But, I came through the BLE stack document and find out it is possible to have simultaneous connections with the BLE peripheral device upto 8. I have been trying to have multiple connections of the BLE, like I want the device to be connected as well as advertiser so that it is possible to connect to with other central devices.Do we have any examples in the STM32WB SDK which shows this behavior of connecting with multiple devices?If yes, please let me know. I have tried my side, changing fe

I'm working on recording audio synchronously using multiple I2S microphones connected to different SAI subblocks on an STM32H7. I’m trying to synchronize all four SAI subblocks to ensure aligned multi-channel audio capture.So far, I've successfully configured SAI1:SAI1_Block_A as Master RX (Asynchronous)SAI1_Block_B as Slave RX (Synchronous to same SAI). This internal synchronization works fine, and both DMA callbacks are triggered as expected.However, when I configure SAI2_Block_A as a Synchronous Slave to SAI1, I encounter an issue:The DMA for SAI2_Block_A never completes (no callback, no data).But I can still see Data signals on the logic analyzer, coming in from the mic.I’ve double-checked the physical wiring — BCLK and WS from the master are properly

hi,Previously i was using STM32L010K8TX which has 8K memory. I did OTA update in this device via Uart with help of external controller which receive hex file from User. Currently am using STM32L010R8Tx which has 64K memory. And i tried the same OTA program to update the application in this new device but after OTA update the user application is running proper.The external device which receive hex file has a debug communication port to monitor STM32L0 device by communicating in UART. After updating the application the UART communication not at all responding to external device.After completing the OTA update am using GO command to run application (0x08000000) and making Boot Pin Low ( which is making HIGH When Entering to OTA mode). Am using same OTA file commands flow to update which was used for previous device (stm32L010K8Tx) including the memory locations.  but in new device after updating the OTA it stops working Ua
