Hi everybody,First of all I don't have experience in FOC.I have profiled the motor, and the procedure was succesfully completed.I use the motor profile to create a FOC project.When I try to start the motor using the Motor Pilot an Overcurrent Error appen (in both mode speed and torque).Now in normal motor drive the closed current loop regulate the 3-phases motor current by monitoring the current and comparing it to the setpoint created with torque reference respectto the electrical motor angle, this means that if no short circuit is present, is not possible to get Overcurrent error.Now in FOC the electrical angle before the motor start must be generated in some way that is not clear to me.I try to change some paramiter as suggested in the help of Overcurrent error, but nothing change.Any try give always Overcurrent error.Using an osclilloscope to investigate, no current flow to the motor phases but systems give this error.Board is ok because with 6 step methode everything work correct.

Hi,I´m trying to get a STM32H747 Discovery board together with USB Host to operate at 1.8V VDD.At 3.3V VDD_MCU USB is working fine!What I´ve done:1. Removed jumper on JP3 and supplied VDD_MCU with 1.8V.2. Removed SB10 and supplied VDD33USB with 3.3V.3. Removed R33 and supplied USB_VDDIO (pin 32 on USB3320) with 1.8V.4. Verified that R136 is not mounted and R137 is mounted.What is working:A. The MCU is working fine at 1.8V. I´m running at 400MHz at voltage scale 1 (using the SMPS).B. VBUS is started (USB3320 controls U2) and LD7 lights up.C. When a usb device is inserted, its looks like its recognized. The usb stack connects a device, initiates a reset and then I get Control Errors. A had a look around the forum and found this post:https://community.st.com/t5/stm32-mcus/how-to-check-compatibility-on-usb-ulpi-transceivers-with-stm32/ta-p/657275However, the REFCLK for the USB3320 is 24MHz, so not sure that post above is what I´m seeing.The reason I need 1.8V IO operation is that I´m

Hi,I have downloaded "GestureEVK_v1.5.0" and tried "gesture recognition" function.It can be launched by GUI and worked well.I also downloaded "STSW-IMG035_F401" and tried to run "gesture recognition".However, it keeps printing the messages as shown below.I have no idea how to let "STSW-IMG035_F401" start running "gesture recognition" and output results through UART after downloading to NUCLEO-F401RE?(No need to enter a start aommand.)Could you guide me in detail about how to modify the code of "STSW-IMG035_F401" to achieve this objective?Thank you. Hardware: NUCLEO-F401RESoftware: STSW-IMG035_F401Sensor: VL53L8IDE: STM32CubeIDE 1.16.0

Hi. I have question regarding VL53L8CX ToF sensor. The minimum distance is 2cm. The space between the objects being measured is less then that. Was wondering if it will be possible to reflect the light off from a mirror at 45 degrees to increase the distance between sensor and object being scanned? Thanks for the assistance Jonathan

During the user-defined BL upgrade process of the STM32, is it possible to keep an IO pin, which has already been pulled high in the user code, at a high level throughout the entire sequence of steps: 'jumping from the user code to the BL, erasing and writing the flash, and then jumping back to the user code after the upgrade is complete'? This IO pin is not used during the upgrade process. The essential requirement is to avoid resetting the peripheral states during the BL upgrade process.I noticed that my IO pin was automatically reset after jumping from the user code to the user-defined BL code.

I am interfacing many 5.2VDC signals with an STM32F103VET6 MCU, using PB0,PB11,PD9,PD10,PD11,PD12,PD14 as input. According to the datasheet these pins are 5V Tolerant. In the past, regardless of a pin's "tolerance" to 5V I have always used a level shifter to change this 5V signal to a 3.3V signal before it gets to the MCU; Just to be a safe voltage. This application I am trying to limit the number of parts on the PCB for small size. Testing on the designed board seems to work and the MCU seems to tolerate this well, but for long term use in the field is it better to run this signal through a level shifter or does it not matter since the pin is "5V Tolerant"? The STM32F103VET6 MCU manual shows "5.3.14 I/O port characteristics,,If VDD=3.3V＞2V,VIN max can reach 5.5V"

STM32f334 在Stm32cube programmer中如何不改變RDP的情況下，驗證MCU內部程式為正確的，透過找出沒有被RDP1鎖住的FLASH去驗證，或是如何透過改寫OB來驗證?Translation:How to verify the correctness of the internal program of STM32f334 MCU in Stm32cube programmer without changing RDP, by finding the FLASH that is not locked by RDP1, or by rewriting OB? 

I posted recently about getting set up with the demo for the GUI application, and got great help from @SRomeo. I've now moved on to the SingleAccess Chain demo, and could use some more help if you don't mind?I am using the C4ML1T, ISOSPI1, and 2 BMS63EN boards each connected to a BMSHOLD cell holder. The first device has 8 cells connected to it, the second has 4. In both cases, there are cells occupying slots 1, 2, 13, and 14.In AutoDevKitStudio, the AEK-POW-BMS63ENCHAIN component is set up with a single chain, with two devices. I have connected the ISOSPI1 board to the C4ML1T as per the allocated pins visible on the board view, below.Once the code is compiled and generated, and the board is flashed, I get periodic LED illumination, and zero values for all data printed to the serial terminal. See video below for hardware behaviour, including how the frequency of the LEDs changes with a reset.I suppose my first question is am I interpreting the board view pin designations correctly? NSL

Hi folks.I have been working a couple of days on a project involving the STM32G070RB. The devices uses two uarts : one for serial comunication throug a USB-serial converter and one for modbus comunication.Both worked OK but now the STM32CubeIDE mark the following lines with "missing ';' " indexer marking and the UART4 stoped to work (both Tx and Rx) and the UART2 Rx IT doesnt work too.   __HAL_RCC_GPIOD_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOF_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE();  ¿What could be the root cause? The compiler gives no warning or error in the compilation.Thanks in advance.  

I've updated from TouchGFX Designer 4.24 to 4.25 and I've noticed that the example projects won't load the previews. Same machine, same internet connection4.254.24 

I have a board with the STM32F407ZGTx, which has space for an SRAM/PSRAM expansion, using IS62WV51216BLL-55TLI. I installed it, everything was fine.I worked with the old 68000 processor, which had 2 signals, UBS and LBS if I'm not mistaken. Upper Byte and Lower Byte. It was 16 bits too... and I could create a char* variable (C++) in memory, and it would write normally to even and odd addresses (even addresses were d8-d15 and odd addresses were d0-d7). Well, here, on the STM32, it seems that the NBL[0-1] signals are useless. I set byte access (as in the images), configured everything, and it only writes 16 bits.I made a small test program below, and it doesn't work. It seems that it always writes 16 bits. Could someone help me?I want to do the basics. A char* variable, write sequentially, and read later in the same way. I thought the FSMC did the same thing as the 68000, since it works with memory.I even looked and searched on the NET, even in an Article, like the one attached, and the

I am using NUCLEO-U031R8 board and MCU is STM32UO31R8while reding reference voltage by using below code #define VREFINT_CAL_ADDR ((uint16_t*) (0x1FFF6EA4UL)) ADC1_COMMON->CCR |= ADC_CCR_VREFEN; uint16_t Internal_voltage_reference = (uint16_t)*VREFINT_CAL_ADDR; I am always getting 0xFFFF what could be the issue?Code formatting applied - please see How to insert source code for future reference.

Hi guys,Can someone explain to me why there is no ESD protection for this circuit?Or is it not necessary?Thank you

We had been evaluating with STM32U5G9J-DK2 board and have generated GUI code. We do not use Video or JPEG. For our production board we are using STM32U599VJ MCU which does not have JPEG module. So I am stuck with this code that has JPEG DMA usage. How do I tell touch GFX not to use JPEG peripheral and generate code for STM32U599VJ MCU? ThanksSansh

Good morning,I am using an STM32G4 Nucleo-32 board (MB1430) and want to drive Relays with its GPIO; I need to know the maximum current that can give a GPIO. I searched on the datasheet of the STM32G431x6 , the maximum power that can be delivered, but found no values. Could someone tell me where to find that info?

Having issues generating random numbers while being connected via BLE.In general use, HAL RNG works fine, and I get a random number without timeouts.BUT,Upon finishing the connection flow,connection mtu exchange pairing ,I start to get timeouts when trying to generate a new random number.Increasing the timeout , initializing,  did not resolve the issue.I am currently trying to use HCI_RND command instead in the hopes it will get me my random number.If it helps, I am on one of the latest BLE stacks 1.20 or 1.21Cheers,and let us all have random numbers when connected!

I'm trying to graft an SD card onto the U5G round display development board.  CN9 brings out all of the control and data lines for SDMMC2.The problem that I am seeing is that the SD device will not initialize (MX_SDMMC2_Init) due to a timeout in HAL_SD_Init -> HAL_SD_InitCard -> SD_powerON -> SDMMC_CmdGoIdleStateCurrently I have VCC to the card plugged into 3V3, ground, clock, and 47K pull-ups to VCC on CMD and the 4 data lines.I've tried using level shifters to use the 1V8 signalling on the processor side and 3V3 signalling on the SD card side, 4-bit SD, 4-bit SDIO, 1-bit SD, and 1-bit SD with the signals simply pulled up to 3V3. All give the same result, timeout on Go-Idle-State.The card is formatted and works properly on a PC. I've got test programs on a F479 Discovery board working with SD cards under FileX, and I tried making the hookup as close as possible to a U575 EV or the 429 Disco, but this U5 is not cooperating.Given that this board uses 1V8 levels and SD card

Hello everyone,Based on the screenshots attached, I couldn't understand the formula obtained for the OCP feature of this inverter board.3 phase currents are read through the shunt resistors, got offset, and amplified by the op-amp ICs. So far so good!But PC1, PC2, and PC3 are tied together using 3 one kilo ohm resistors, then the common node is fed to the comparator pin of the MCU to do the OCP task.I am wondering how the Equation 2 is obtained for implementing over current protection, and why it is like this. Why is the G.Rs.Ioc term divided by 3? If you could guide me, it'd be awesome, thanks. 

How to set the gain of GAIN0/GAIN1 pins 30/31 of TDA7491HV?  

I am working on a project with the STM32G0 series microcontroller. There is a requirement in my project to identify a BOR (Brown-Out Reset) independently. In the previous version of the project, we used the STM32L4 series, where there is a reset flag bit (BORRSTF) in the RCC_CSR register to specifically identify the occurrence of a BOR.In the STM32G0 series, there is a reset flag bit (PWRRSTF) available in the RCC_CSR register to indicate a power-related reset, which can be due to a BOR, POR (Power-On Reset), or PDR (Power-Down Reset). However, there is no dedicated reset flag for identifying a BOR alone.Is there any other method available in the STM32G0 series to specifically identify a BOR? 

Hello everyone, I am currently using a 64-bit Windows 7 operating system and I am interested in using STM32CubeIDE for my development projects. Before proceeding with the installation, I would like to confirm whether STM32CubeIDE supports a 64-bit Windows 7 operating system. Could anyone please provide information or share their experiences regarding the compatibility of STM32CubeIDE with a 64-bit Windows 7 OS? Thank you in advance for your assistance!Best regards

Currently, I'm running the M4 core by loading it through the A7 core.Is there any way to make these two cores start independently, without interfering with each other, and only perform communication?

 MacOS 15.3.1.  CubeIDE 1.18.0. Firmware STM32Cube FW_U5 V1.7.0.I  was tracking down an issue with SD cards on SDMMC2 on an STM32U5G9N not wanting to start.I found that HAL_SD_MspInit calls:__HAL_RCC_SDMMC1_CLK_ENABLE();instead of:__HAL_RCC_SDMMC2_CLK_ENABLE(); 

Hello,i have a question concerning the SD-Card functionality and the licensee fee of the SDMMC implementation of the STM32H723ZG.My goal is to log some data on the card. According to the documentation, the FatFs-Filesystem can be used under a BSD-style license. How About the SDMMC Protocol? The SD Association states that a licensee fee must be paid if you plan to develop a host device. Has this fee already been paid with the purchase of the STM32?
