Hello there,I have sensorless 3-phase bldc motor. I am using MC Workbench for Sensorless FOC algorithm with STEVAL-SPIN3201 board. I've run my motor at torque mode and it seems okay. But, when I loaded motor does not produce any torque and immediately stops. What can be the problem? I've attached screenshots of GUI settings file.

I bought a stm32f429i-disc1 board and I want to learn how to communicate to stmpe811 with I2C protocol, now I'm a little confused. According to stmpe811's data sheet, its address is 0x82 because its A0 pin is connected to ground, but board's schematic(MB1075) shows that address is 1000001(7 bit). Is the address on schematic missing a 0 on the far right?

i´m new here, and i´m starting to work with STM32F103C8 (blupill)I´ve created a very simple code. It´s shown in image down.The problem is:The editor doen´t recognize the variable type int8_t and int32_t (probably int16_t too).And when a try to build the code, the editor show me a message: adc0 undeclared.I don´t know how to resolve this. I´ve tried to declare stdio, nothing changes.Does anyone could ,pelase, help me??Thanksss

Hello.I am in need of inputting large strings of text (larger than the width of the screen) using keyboard. I have managed to get a working keyboard, but after increasing the buffer size, the text is being cut off after it leaves the widget area.I want to be able to scroll the written text left and right, or maybe even up and down. This would require me to somehow get a Scrollable Container as a parent for the text area, or rather the Rect textAreaPosition (which is part of Layout structure), which the text is being drawn on.I have managed to increase the size of drawn text dynamically by calling setLayout(&layout) after changing the size of textAreaPosition, which means that Scrollable Container could work (although I wonder how will calling this method so fast impact the performance). The question is how to add Scrollable Container as a parent of Rect textAreaPosition, without changing the provided Keyboard widget code? Is it doable? Maybe there is an easy way of doing what I wan

Hi,me and my team are working on a project on STM32MP1-DK2. While everything is working fine on the previous ecosystrem release (v3.1.0),after updating to the latest release v4.0.0, our demo stop to work, even after recompiling.This is caused by the following code:wl_display * display = wl_display_connect(NULL); if (display == NULL) { std::cout << "can't connect to wayland display" << std::endl; return false; }wl_display_connect keeps returning null and thus I cannot get the current Wayland display.What's more interesting is that even the built-in "weston-info" tool has the same issue and in fact it doesnt work.Can anyone help?Thank you

Dear Support,Please help to share marking information for the part number L99DZ100GTR?The marking info in the datasheet do not show the date code.

I am trying to run a debug session with the built application which is built upon the secure bootloader. Note: All security mechanisms are disabled for debugging purposes.The issue seems to be the combined elf file. Loading this using a debugger, the target boots up into the bootloader. The bootloader does not find a valid application in the master slot and erases the flash, since it is not empty and asks for an sfb-file via YMODEM.Flashing the target with the resulting binary file, using cube programmer, works as expected.But i want to be able to debug my application. Have anyone else had this issue ?regards,Martin

Our products integrate the above PNs and we would need these documents in order to submit them to the cerification laboratory.As reported in the datasheet both ToF sensors are "designed to remain within Class 1 laser safety limits under all reasonably foreseeable conditions including single faults in compliance with IEC 60825-1: 2014 (third edition)."  Thank you

We are using the P-L496G-CELL02 demo board and want to connect an external device through an UART.Is there (for example USART1) accessible for external connection? Which ports are connected to the Arduino compatible interface? Is there an UART aviable?Or are there schematics of the board aviable?Regards,Michael

Hello,in STM32CubeProg v2.11.0, in the Registers (BETA) tab, peripheral ADC, register SMPR1, the entry SMP0 is missing (it's the VREF INT channel).Best,Nicolas

Hello,We are having an issue with the STM32H753IIT6, which contains several RAM sections... namely ITCMRAM (0x00000000), DTCMRAM (0x20000000), RAM_D1 (0x24000000), RAM_D2 (0x30000000), RAM_D3 (0x38000000).The problem that is occurring: When loading variables specifically into RAM_D2 and RAM_D3 (0x30000000), the generated Hex file is including this section as a loadable section, which in turn causes issues in STM32CubeProgrammer when it tries to load that section. When the (NOLOAD) option is applied to the linker script, it does fix the problem, however we do not like this option as we then have to specially treat any initial values in the code...Is this a known issue?/* ****************************************************************************** ** ** File : LinkerScript.ld ** ** Author : STM32CubeIDE ** ** Abstract : Linker script for STM32H7 series ** 2048Kbytes FLASH and 1056Kbytes RAM ** ** Set heap size, stack size and stack location according ** to application requirements. **

Hello everyone,I have a NUCLEO-H723ZG board and its user manual UM2407 does not contain its schematic. Is there a way to have a look at the board's schematic somewhere?Thanks in advance

Hi, I create my new project follow the SubGHz Phy Ping Pong example project.In the example project, the RTC configure in "Free running Binary mode". In my project, I configure the RTC in "Free running BCD calender mode" therefore no Radio Rx Timeout after the Radio.Rx() function called. Someone know how to fix this problem in RTC Free running BCD calender mode. My project below.Please support me.Thanks.

I've been trying to implement over the air updating on a board with the mentioned MCU. According to the reference manual of the G4 MCU series, dual bank operation should be supported, but the Flash memory characteristics of the G431xB series only mentions one bank. Furthermore "FLASH_OPTR_DBANK" is not defined in HAL, which suggests that it isn't an option. Does this mean that this specific G4 series doesn't support this operating mode?

Exist some internal way to do this ? Itry this , but clock config for CPU2 must be 32MHz ...

Hi Sir,​I'm developing project using STM32WB55 and start from STM32Cube_FW_WB_V1.14.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_p2pServer.everything setup fine with LightBlue Android APP. When I trace and debug code, I cannot hit break if I use "READ" from lightBlue APP. I can hit point if send notify/subscribe and write. Please kindly guide me where I can hit READ EVENT in code. thank you.​btw, I also try STM32Cube_FW_WB_V1.13.0 and other Android BLE APP. The result is same.Best regards,Chang​

Hello,I am facing a problem for the first time with one device while doing something that has worked perfectly on several (dozens) before of the same model (STM32H755IIT6).I am updating the firmware of the device with a custom update tool that has closely the same protocol as flashing with the stm32CubeProgrammer, namely at the writing request "0x31".The problem is that, at this device, a part of the data is not being written, though I get a positive response from the request, when I am flashing the m4, falling after the address 0x08010040 and for several (not always constant) blocks.Using a saleae, I can see that both using the update tool or the stm32CubeProgrammer, they perform very much the exact same way (only time differences of ms), for the same file even the same information. E.g.:Request: 0x31 0xCEResponse: 0x79Request (Address and checksum) e.g.:0x08 0x00 0x00 0x00 0x08Response: 0x79Request: data length, data, checksumResponse: 0x79This is performed with the same content by t

Noob question - can I use AI with the STM32WL SoC ?I want to train a model and then use STM32Cube.AI to put it on STM32WLE5CC. This is so I can use AI on the end device and transmit data using LoRa all using the one chip.Is this possible ?Many thanks in advance.
