Hello Guys!Im using STM32H743IITx MCU and W25Q128 QuadSPI. i want to know that how to use MDMA feature for QuadSPI.Thanks.

Hello folks!The STM32H743VC Processor has two pins, that have a "_C" at the end of the name:Pin 17: "PC2_C" and Pin 18: "PC3_C" When I want to know what the C means, the Datasheet  says: refer to the reference manual.DS12110 Rev 10 - page 67 - Pin Description, Footnote (6) on Pin 17 and 18:There is a direct path between Pxy_C and Pxy pins/balls, through an analog switch. Pxy alternate functions are available on Pxy_C when the analog switch is closed. The analog switch is configured through a SYSCFG register. Refer to the product reference manual for a detailed description of the switch configuration bits.The Reference Manual tells me, that I can close an analog switchRM0433 Rev 8 - Chapter 12.3.1 - Page 548+: (for PC2_C):This bit controls the analog switch between PC2 and PC2_C (dual pad)0: Analog switch closed (pads are connected through the analog switch)1: Analog switch open (2 separated pads)But there is no further information, where this connection goes to. I have no add

Hi,I'm trying to run the whole ST-Linux-stuff on one core only to have the other one available for a time-consuming application. However, it seems the kernel-parameter isolcpus is not used, dmesg gives an output[ 0.000000] Kernel command line: root=PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582 rootwait rw earlycon console=ttySTM0,115200 isolcpus=0 [ 0.000000] Unknown kernel command line parameters "isolcpus=0", will be passed to user space. [ 2.309368] isolcpus=0The message is correct, also with this parameter set, the processes are spread over all cores.What could be the problem here? Thanks! 

Hello,ST experts I have read Wiki on https://wiki.st.com/stm32mcu/wiki/Connectivity:Introduction_to_LoRaWAN. And we want to build a LoRAWAN based on STM32WL series MCU. But it seems not very clear what is the performance of the LoRA gateway. E.g. 1km distance from endnode to gateway, 100 endnodes, about 1K bytes per endnode, can a single gateway afford it? Or how much I need? Best RegardsYang

The problem ethernet link with NUCLEO-H755ZI-Q.The conditions are as follows:Board: NUCLEO-H755ZI-QEthenet select core: CM4STM32Cube_FW_H7: V1.12.1LWIP: V2.1.2DHCP clientIn this case, the Ack from the DHCP server could not be confirmed as being received.dhcp->pcb_allocated is set to 0 (in function of dhcp_recv()).A similar error has not occurred with CM7.Do you happen to know the reason for this?

Can someone tell me if I’m understanding this correctly?In the documentation for the STM32F030R8T6 chip, specifically the "RM0360 Reference Manual", there’s a diagram showing how to connect an external crystal oscillator ("Figure 12. HSE/LSE clock sources"). In this diagram, the crystal is connected directly to the OSC_IN and OSC_OUT pins, with no series resistor on the OSC_OUT line to limit the drive level.However, on the STM32F030 DISCOVERY board, there is such a resistor – R22 – even though the crystal is not installed by default. I added the crystal I wanted to use and measured the current through it (using a current clamp), and it became clear that it was being driven beyond its specified power limits. That’s when I realized the need for the series resistor (R22). I calculated the appropriate resistance value and installed it – but it didn’t reduce the current through the crystal at all.After further investigation, I discovered that the OSC_OUT pin on the microcontroller is actual

I use IIS3DWB with no LPF2 enabled, and I understand the Frequency response shown in Figure 13 at page 20 of the datasheet.I know that I can enable low-pass LPF2 filter, but from the same graph I don't understand if this filter can be enabled as a hardware anti-aliasing filter, or not.I mean, after I enable ODR/4 (as an example), is it safe decimating ODR by 4, or not?This decimation is safe if LPF2 is a hadrtware filter that "cuts away" every frequency above (ODR/2)/4.From the graph it doesn't seem so, but i't not 100% clear IMHO Thanks in advance for the clarification.

I was using STM32CubeIDE version 1.16. It was crashing occasionally. Then I wanted to update to version 1.18. It started to crash constantly while updating. Then I cleaned the program with all its extensions and reinstalled the new version(1.18). But the problem was not solved and it keeps crashing.I checked the form and your answers. I couldn't find any solution for this.Below is a screenshot of the errors I receive.  

I have 5kW QS138 BLDC motor within my e-bike project with my own motor controller electronics. I have measured inductance and series resistance from the motor with a precision LCR meter: Lq [mH]Rs [ohm]Ld [mH]Rs [ohm] Ld/Lq       120 Hz0.0310.0030.0210.003 0.671 kHz0.0300.1110.0210.067 0.6910 kHz0.0270.2100.0190.148 0.7220 kHz0.0250.5750.0180.390 0.72At MCSDK one inserts the motor parameters and other drive settings. My PWM frequency is 15 kHz with equal FOC update rate. Now should the motor parameters be inserted to the program as measured with this PWM frequency? Or are they assumed to be "static DC values"?By using "15 kHz" values, I get following parameters: Rs = 0.2 ohm, Ld = 0.019 and Ld/Lq = 0.72Going to the "DC end": Rs = 0.003 ohm, Ld = 0.021 and Ld/Lq = 0.67Any suggestion which is the correct end to start iterating? 

When I enter standby mode using HAL_PWR_EnterSTANDBYMode(), the program is expected to halt at __WFI() until awakened, after which it should restart from the beginning. The function is shown as followed.  However, in my case, after executing __WFI(), the program immediately jump out from __WFI(), proceeds to execute subsequent statements. Debugging shows that the C1SBFflag in the PWR_EXTSCR register is not set, indicating the MCU failed to enter standby mode. This issue occurs specifically when disconnecting a peripheral (indirectly connected via a slave chip).I check the SLEEPDEEP bit in SCR register and LMPS bits in PWR_CR1 register, all bits is set to 1 when program stopped at the breakpoint of CLEAR_BIT(SCB->SCR, ((uint32_t)SCB_SCR_SLEEPDEEP_Msk));shown in the picture.I also check the WUF flags in PWR_SR1, no bit set to 1. I would like to inquire about the possible reasons that might prevent an MCU from entering standby

STM32CubeIDE 1.17.0, Win 11 x64I have a number of related projects in the space workspace (WS). I can copy & paste them into the same WS with no problem within CubeIDE. New project folders are created within the WS directory & show up in the Project Manager list. All these project folders exist within the WS directory.When I import a project from outside the WS using Open Projects from File System... they import fine & show up in the Project Manager list. BUT when I try to cut & paste a project folder from outside of the WS directory into the WS directory via Windows Explorer & then try an add it to the Project Manager list in CubeIDE via Open Projects from File System... I get nothing, no import error messages, nothing. The project file doesn't appear in the Project Manager list, nothing!Anyone know why this is?

Hi,The recent webinar with your partner Edge Impulse on 26th March was useful to taste the capabilities of STM32N6. Until now in my previous STM32 MCU projects are built with ST official tools like STM32CubeMX. But there is no much information available on using official ST tools (not your partner tools) to use STM32N6 devices. Can you please provide more training material on this new device and using it with the ST official tools, probably providing a workshop on STM32N6 please?

When "Middleware and Software Packs" > STM32_WPAN is enabled in  CubeMX, a duplicated initialization's code for uwTimclock is generated: That code is outside the if-else block overriding the previous configurations which could produce issues.   Any idea about what could be wrong?   Note: I attached the .ioc file. Details: CubeMX version: 6.14.0 File: stm32wbaxx_hal_timebase_tim.c

I don't know the internal structure of the TS3330AMR IC.Is there a functional block diagram of the IC's internal structure?

I developed a multi-port charger with multiple STUSB4710A and companion ST1S14PHR with the recommended bill of materials. The evaluation kit worked fine however my board does not work consistently. I read back the status register and detecting undervoltage.      uint8_t vbusStatus = readRegister(STUSB4710_I2C_ADDR, 0x10); // MONITORING_STATUS    Serial.println(":magnifying_glass_tilted_left: Checking VBUS Voltage Faults...");    if (vbusStatus & (1 << 0)) Serial.println(":warning:  VBUS Overvoltage Detected!");    if (vbusStatus & (1 << 1)) Serial.println(":warning:  VBUS Undervoltage Detected!");    if (vbusStatus & (1 << 2)) Serial.println(":warning:  Power Good Fault!");

Can anyone help identify this chip, please!Thanks in advance!!

I tried to generate code using stm32cube ide to run lwip and tried to ping the board. But it is not working. Is it possible to generate code that runs without any modifications in the generated code?

My organization is currently planning to develop a monitoring unit that will connect with a mobile app via NFC. For this, we have chosen the ST25R3916 NFC module, with the STM32WLE5 series controller as our main MCU. Recently, we started working on the NFC-A configuration for active peer-to-peer communication using the ISO14443A standard.We are currently encountering issues with lagging during testing and have been unable to find reference sources online for implementation and testing. We have come across a video that demonstrates some testing methods through a GUI, which I will share below. Additionally, we found some source files for the ST25R3916 module, which I will also provide links to. However, the problem is that the complete implementation is in C, while we are looking for a C++ implementation since we are using Mbed OS for development.We also have a key question: is it possible to implement FOTA (Firmware Over-The-Air) using NFC in passive mode? If so, we would appreciate gui

We are developing a product using the STM32WB55 chip and using the S.T W.P.A.N stack. We intend to release our product with a Bluetooth certification / logo, so we need to register our company to get a company I.D right ? Do we need to use the company ID, or do we need to register a 16bit unique U.U.I.D (and pay for it ?). I don't think it's allowed to use the company ID of St Microelectronics, I don't want a lawsuit from either the Bluetooth S.I.G or St Microelectronics, but I also don't want to explain to my boss we have to spend more money if it's not necessary because we are a startup. I also didn't found a way to set / get the company ID from memory or flash. Is it possible to use the S.T W.P.A.N stack to do this or do we need to modify the source code generated by STM32CubeMX directly ?

Dear I hope you are doing well.I would like to confirm if the default antenna power of the STM32WB05KZ board is set to 0 dBm ?  Additionally, could you please guide me on how to modify this power setting?Thank you in advance for your support. I look forward to your response.Best regards,

I followed 'STEVAL-MKI109D Professional MEMS Tool motherboard for MEMS adapter boards' and installed MEMS Studio.I then placed STEVAL-MKI250KA on STEVAL-MKI109D by following UM3420 and AN6173.  When I boot MEMS Studio, it just does not recognise the board either via bluetooth or serial.  I also installed https://www.st.com/en/development-tools/stsw-stm32102.htmlAny ideas what I am doing wrong?

Dear Gfx Team1. Could you consider adding a 'Refresh' button to the Typography ?With GfxDesigner open, when I copy a font to ./assets/fonts, the font is not recognized in Typography. Close/Open of GfxDesigner is necessary.2. Could you make slider bigger and more visible please ?3. Could you add a text field showing an example of the font?4. Could you make the dropdown list searchable so that typing filters the items containing the typed text?Thank you  

I am working with the LSM6DSO16IS in MODE2 configuration with ISPU enabled. I have some questions regarding the MDRDY (Master Data Ready) signal:1. How is the MDRDY signal handled in MODE2 when using the master I2C interface with external sensors?2. Is there any specific configuration needed in DRDY_PULSED_REG (0x0B) for proper MDRDY operation in MODE2?3. Can you provide information about the timing relationship between MDRDY and the external sensor's data ready signal in MODE2?4. Are there any application notes or reference designs specifically addressing MDRDY usage in MODE2?Current configuration:- Like JP4 from X-NUCLEO-IKS4A1 SCH, the INT2 of LSM6DSO16IS is connected to the interrupt output of an external sensor- LSM6DSO16IS in MODE2- ISPU enabled- External sensor connected via master I2C- Using X-CUBE-ISPU framework

hello. I was using PA9 pin as an interrupt in a project made with Stm32F072CBT6. I am working as Stm32F072CBTx in cubeide. The card I am working on accidentally installed Stm32F072C8T6. only difference is that it is visible in flash but PA9 pin can be defined as interrupt in the same way but the function does not work. Is the fact that the processors are different a reason why the interrupt cannot work?. I do not get any overflow error caused by flash.
