Hi,I am looking for a STM32 micro that can control this DSI display (datasheet attached).But the display has 4-lanes DSI interface and cannot seem to find any STM32 with 4-lanes DSI. The microcontroller selector tool only has "MIPI-DSI" option without lane specification and all the micros I looked at so far seem to have only 2-lanes.Are there any 4-lanes micros?If not, how can I control such display? Are there some bridges ICs (I could not find any)?Thank you :)

Hello,I am trying to use WB55 as a Zigbee device on HomeAssistant. I have made some progress so far, and I can use it as an OnOff switch on HomeAssistant and report my switch status in real-time to HomeAssistant.At first, I added WB55 to HomeAssistant and it worked very well. I modified the client to server based on the demo, so it changes the OnOff state every second, and I can see its status changes in real time on HomeAssistant. But if I restart the device, I won't see any status changes again when WB55 is reconnected to HomeAssistant. I didn't do anything in HomeAssistant, reconnecting looks completely automatic.I provided the source code I modified and its logs. I hope to receive an answer.Thank youWeng

Our board has an STM32L031 as a SPI master with two AD5271 Digital Pots (R24 and R25) as SPI slaves.  After power-on both digital pots can be read (return default of 511).  The first digital pot accessed can be given a new value and that new value read back.  The other pot now reads all zeros.  A different value can be written to the first digital pot and read back (so the SPI bus didn't get 'stuck' after the write routine finished).  Once the second digital pot is given a new value, neither digital pot can be read back (returns all zeros).  It doesn't matter if R24 is accessed first or if R25 is accessed first; the first pot accessed can be read-modified-written.  A UART port provides debug output: Accessing R24 first:--------------------Configuring digital pots...R24 config is set to 511R25 config is set to 511R24 config is set to 156R25 config is set to 0R24 config is set to 188dpotSetRDAC(R25) failed, tried to set to 68, is set to 0R25 config

Hello,in the STM32F7 it is possible to enable instruction prefetch and in the same time disable ICache. Then I suppose that the prefetching does not put the prefetched instruction in cache. Is it correct?Thank you

Hello, I am trying to install the SDK to work on the STM32MPU257F-EV1 Development board and I followed the instructions for the x86_64 Architecture, however when I use the command echo $ARCH it says the architecture is arm64? Is that what should be displaying? I feel like it should be x86_64 right? Thanks! Carson

Hi People, for the since start of year i've been setting up boards with Texas C2000 , and for the past 6 months infineon tri-core processors.  I may be changing jobs and it involves STM32 so i'm getting a head start. I have a STM32373C-EVAL , as i need TFT display and CAN. i have attempted to make a 'blinky ' project. Compiles fine but when it runs it hangs on the oscilator start up . Fresh install of STM32CubeIDE so used the config tool and let it do all the defaults.. The dev kit has solder bridges for crystal - they are open , but i've let it use the PLL.  it wont let me  When running in debug it 'hangs' on stopping the code , its in the error handler from the system clock settings , if i comment out the error handler it runs .    void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDe

Hello,Who should I contact to obtain the firmware of the P-NUCLEO-LRWAN2.Thanks

I'm trying to configure the STM32WB55 Nucleo Pack USB Dongle with the Mac_802_15_4_Sniffer_Dongle.bin but the Start Address is empty:  What value goes here?

So I tried upgrading the firmware. I first downloaded the STM32CubeProgrammer, linux version, on the my computer. Then I got the device into DFU mode as per instructions and attempted to flash the new firmware using the STMCubeProgrammer software. Afterwards, it did not restart and no longer goes into DFU mode. It does not show in lsusb at all. It previously did as an STM device in DFU mode, but now its no show. The MCU is an STM32H743. I found an SWD port on the PCB and connected to it, again using the STM32CubeProgrammer software but with an STLinkV2. On selecting the STLink option and clicking connect, the program reads the MCU details, but fails to read any data or flash a binary file. When attempting to flash a new firmware I am getting 3 errors:   Error: Flash loader cannot be loaded   Warning: The core is locked up   Start operation achieved successfully   Can I unlock the core and get it into DFU mode, or at least flash the new firmware? Beyond ins

Hello, ST experts STM32U595VJT6 is used on the design. The OTG part of MCU works well on USB device mode. And it functions as USB flash disk.  But when I check the logical level from OTG device status register(address offset is 0x808), there is something wrong. If the USB cable is plugged in, it is all right, DEVLNSTS[1:0] are all zero. But when the USB cable is move out, DEVLNSTS[1] is 0, DEVLNSTS[0] is 1. That means USB_D+ is 0, USB_D- is 1. But the real logical level of USB_D+ is 1(about 3.3V), USB_D- is 0.Am I missunderstand something? Best RegardsYang

Hi,We are using the chip PowerSTEP01 in our design. In the datasheet, it is mentioned in the application diagram that the VDDIO pin can be powered from the VREG pin. However, the X-NUCLEO IHM03A1 evaluation board design shows that it is powered externally. Which one is the correct way of doing it? Are there any problems or limitations in powering the VDDIO from the internal regulator? Best Regards,Biju

Hello everyone,I'm using Board NUCLEO-U031R8 for testing now.I have an old FreeRTOS project designed for a power-saving application, and I am preparing to migrate it to a new IC STM32U031 series MCU.In the old project, setting configUSE_TICKLESS_IDLE to 1 allowed the system to enter low-power mode when tasks were idle, and the low-power support feature provided by the manufacturer.So I started with STM32CubeMX to create a simple project and install "X-CUBE-FREERTOS" middleware (CMSIS RTOS2), and set configUSE_TICKLESS_IDLE to 1. then using STM32CubeIDE to import the .ioc file, last adding a long-duration LED blink task to make sure the system would entry tickless idle mode.The LED operates as expected, but I noticed that the current consumption averages around 5mA, which suggests that low-power features might not be functioning as intended. Do I missing something or wrong understanding?Is there a recommended way to achieve low-power mode with tickless functionality in FreeRTOS?RegardsK

Hello everyone,I'm using Board NUCLEO-U031R8 for testing now, and I started with cubeMX and initial component below:System Clock configure to HSI (16MHz)FreeRTOS with USE_TICKLESS_IDLE as 1 (built in functionality enabled), and auto generated two function PreSleepProcessing() / PostSleepProcessing().LPTIM1 with 32kHz LSI and clock presclaer set to Div32, every timer count alomost 1ms, using for replace the sysTick while tickless idle.LPUART1 with 16MHz HSI1, interrupt RXNE/WKUP/ERROR always enabled after system initial done.The task is startup and print information and delay 1 second, then entering an endless loop that includes a 1-second running delay and a 4-second sleep delay, and everything works fine in 1 second running delay.But when sending bytes in sleep, it would occur overrun error when received length > 2, so i toggle an output while interrupt occur. and i saw an weird interrupt while receiving bytes, the record here.To I modify tickless idle part, I disable sysTick

I'm trying to debug a STM32 project on an STM32 IoT Discovery Node Board (B-L475E-IOT01A1) from my MacBook Pro (M1 Max running Sonoma 14.5). Every time I build and start a debug session, the process gets stuck on "Launching : Performing pre-launch check..." as shown in the figure below.When it get's stuck like this, it can't be canceled and the only way to clear the process is to restart the IDE. I am new to this kind of debugging, but I have a feeling this is a problem with the USB connection and drivers because when I restart my computer, it usually works (without changing any of the project settings or configurations).ST-link server is running on my machine, and seems to have connected properly as shown in the output for the following commands.Is there any known way to resolve this error? Restart the drivers or reconnect ST-link? Restarting my computer every time is not really a long-term solution. I'm sorry if this is a dumb question, I am new to CubeIDE.  edit:

I'm using TrueStudio for my previous product coding/debugging.  I downloaded some example projects from ST website,  there are options for IAR/Keil/STM32CubeIDE, is TrueStudio fully replaced by STM32CubeIDE?I'm get used to TrueStudio, is STM32CubeIDE much better than TrueStudio?

Hello,I am investigating in using L5970AD DCDC converter for a 12VDC to 3V3 need.It was advised to me by the ST DCDC online simulator.It's a 20 year old circuit but it it matches the budget, the additional BOM and the efficiency so I am interested.But I don't reach in answering some questions. If one of you can share some return of experience about this chip I am gladly listening.I am in design phase, looking datasheets, and except error I don't find my answers :- The VREF signal is noticed as 3V3. 3V3 is the output I want to create. On the Typical application schematic it seems not clear for me if connecting VREF to the output is okay, or if we need a precursor 3V3 ??? Should we supply a high impedance 3V3 from resistor divided input for example ? I couldn't reach advise about it, the is no paragraph about VREF. Is it an input or an output? What about generating 5V, do we need a 3V3 rail ? Also, even if switching frequencies are different, why not group L5970AD and L5970D in one

Hi,I used a Nucleo-F303RE board as template for my own hardware. Timers and clockfrequency are running fine on the NUCLEO but they are slow by factor 9 on my own hardware. USARTs are running on the exspected baudrate. Factor 9 gives a hint to the PLL block in clock generation. I recently learned that PLL is running on VDDA. I blocked VDDA from VDD with a bead. Is it the PLL?Why does it not lock, where can I check?Poor VDD? Poor blocking VDDA from VDD? Poor XTAL? Something totally different.Why the correct baudrate? THX for hints.Cheers Detlef 

To control a DC motor driver I need to set one pin permanently high and the other is inverse PWM.If I want to reverse the motor direction I need to swap these settings.So I configured both pins as PWM output.But if I want to set one output pin high the following code is ignored:HAL_GPIO_WritePin(GPIOA, MOTOR_IN1_Pin, GPIO_PIN_SET);The pin stays low, maybe because the pin is officially not in GPIO mode?So I thought ok setting 100% duty has the same effect, but when I measure on the scope you see small glitches to zero volt. So my question can be solved two ways:How do I make my PWM output pin accept also WritePin commands?ORHow can I get rid of the small glitches in my 100% duty cycle?

Hi,I am working on STM32MP133FAFx (I2C Master) for I2C communication with STPMIC1 IC (I2C slave) fast mode(400KHz) and HSI clock(64MHz). I2C->TIMINGR = 0x00C0216CFor writing data TXIS flag is getting send and I am writing the register but when trying to read data back from PMIC RXNE flag is not getting set and RXDR register is not showing data.Configuration for reading & writing data is done as per the example code provided by STi.e. used  HAL_I2C_Mem_Read() & HAL_I2C_Mem_Write() functions for 1 byte data transfer. Please help me how to resolve this issue and provide me the solution. 

I want to use the second USB of my nucleo-h753zi board, in a program that checks and graphs the movements and clicks of the mouse that enters through the USB port, but I only see the stlink, there is the init = MX_USB_DEVICE_Init (void);  I used the power in "ext" and in "chgr" but without result.  What am I missing or what am I doing wrong? Thanks  

I want to know the address in the memory map, is it a virtual address or a physical address?
