I am using 12V motor, all the phase I measured 12V, its look like it stuck at brake.what can be the problem?I am using motor 1028m012b - FAULHABER

I recently purchased some secondhand ST M27C128B-12F1 online and am trying to program them correctly. The main information I am looking for is the Device ID, Vcc for writing and verifying (both), and Vpp. I was able to find a datasheet for the M27C128A but am not confident these parameters are the same.Thank you!

How many sectors does the flash memory of stm32f446rc has and what is the size of each sectors ?

I haven't been able to find a recommended footprint (PCB pad layout) for the VL53L5CX, either in the datasheet or anywhere else. When will that be available? Or did I miss it somewhere?

I am using stm32L412CBU microcontroller and I am using both ADC units. The code generation generates this line of code:PeriphClkInit.AdcClockSelection = ADCCLockSelection; which is incorrect according to the structure RCC_PeriphCLKInitTypeDef for this controller, you will find that this member is disabled for this particular controller.

I have designed a board with four seemingly identical motor drivers. The four L6472 are connected to an STM32-MCU via one SPI-interface, chipselect is handled by GPIO. They share a common reset signal, also GPIO. Because of the pull-downs on /STBY_RES the L6472 will only leave reset when the MCU pulls the GPIO up. I have verified with different boards (different production runs/board revisions) and motors that U702/U703 "Wash-Selctor Valve Driver / Dilutor Valve Driver" consistently power up or leave reset with output bridges active, resulting in high current fed into the respective motors.On the other hand, U602/U603 "XY-S-Motor-L/R" always power up as expected - with bridges in HighZ.I can't explain this behavior from the datasheet. Would you have any recommendations?Thanks.

Hi, I am attaching a simple .ioc configuration file with which I generated a new project using stm32 cubeide which when compiled generates a footprint of about 12kB.Frankly, it seems excessive to me, to the point of making this platform unusable for projects with limited memory resources.This problem has escalated in the latest versions of stm32 Cubeide.Is there a way to have greater control over the resources used?

I'm using an STM32F767ZI, and am programming it in C without any additional libraries (bare metal).I believe there is a memory leak somewhere as a memory allocation that typically would work seems to fail after the program has been running for some time.I'm familiar with tools such as dmalloc and valgrind, however an embedded environment is (obviously) very different and adds complications.Are there any reliable tools, similar to the two named above, which could help me to track down memory leaks? Since the system is intended to run indefinitely, it would be preferable if the tool offered functions which can be called from within GDB in order to analyse the currently allocated memory.If not, what is the best way to go about making something like this myself which can give useful info about where exactly the memory was allocated?From searching around, I've come across a variety of (unhelpful for my use-case) answers, including suggesting that dynamically allocated memory should be entir

I am porting some code from the STM32L432 to the STML496. The STM32L432 had a macro that would allow you to stop the USB clock on APB1 (_HAL_RCC_USB_CLK_DISABLE), but the bit in the RPB1ENR1 register used to do this (RCC_APB1ENR1_USBFSEN) doesn't seem to have an equivalent on the STM32496. Is there an easy way for me to functionally recreate stopping the clock?

Hello, I accidentally connected Vcc to the interrupt pin in an X-NUCLEO-NFC06A1, now I don't get any interrupts. Is it terminally burnt or can I configure an IRQ from somewhere else on the board?

Hi,I've come across what seems to be a Designer bug which I don't know how to solve or how to avoid it in the future.I added an animated image to my project that consists of a few images. Afterwards I deleted the animated image and proceeded to remove the images the Designer's images screen.Then, to my surprise, when I tried to compile through the CubeIDE I received the following error message:make: *** No rule to make target 'C:/TouchGFXProjects/FirstApplication/TouchGFX/generated/images/src/image_FullPallete.cpp', needed by 'Application/User/generated/image_FullPallete.o'. Stop.make: *** No rule to make target 'C:/TouchGFXProjects/FirstApplication/TouchGFX/generated/images/src/image_FullPallete.cpp', needed by 'Application/User/generated/image_FullPallete.o'. Stop.If I re-add the images, it works fine. If I try to delete them again, the same thing happens. I don't want these images and I don't know how to get rid of them.Thanks in advance!

HII am a beginner on using touchGFX. I did some tests with an evaluation board and everything works, I was able to do some tests. Now I ask you how should I do to create a new project with a hardware built by me? I haven't found a tutorial explaining how to set up IDE and GFX from the start.

I am trying to change the box colour from Red to Green then Green to blue on every single click but on single click box color directly changes from RED to BLUE..for very short duration it appears GREEN. FYI.hpp  void boxClickHandler(const Box& b,const ClickEvent& e);  enum colorChange{RED,GREEN,BLUE};  colorChange cc=RED;protected:  Callback<Screen2View, const Box&, const ClickEvent&>boxClickedCallback;.cppScreen2View::Screen2View():boxClickedCallback(this, &Screen2View::boxClickHandler){}void Screen2View::setupScreen(){ Screen2ViewBase::setupScreen(); //Add the callback to the box box1.setClickAction(boxClickedCallback);} void Screen2View::boxClickHandler(const Box& bx, const ClickEvent& evt){ if((cc==RED)) { //Change the box color to GREEN. cc=GREEN; box1.setColor(touchgfx::Color::getColorFrom24BitRGB(0,255,0)); box1.invalidate(); } else { box1.setColor(touchgfx::Color::getColorFrom24BitRGB(0,0,255));

HiI have a serious problem with EEPROM emulationWriting and reading commands from EEPROM work well at first glance.When I read the ST documentation related to EEPROM "UM0558", I noticed one thing and that is "swaping". Swap should be done when block is full. To test, I wrote about 1023 4-byte words in one address (Update a unique ID about 1023 time). But for 1024 words an error occurred and from then on everything went wrong.​for (i=0;i<1050;i++){ eewritebuf[0]=i;​ result =  FSL_WriteEeprom(&eepromConf,0,4,(UINT32)&eewritebuf,callback);}​​Why not update for 1024 and later. If everything is correct, it should be possible to update ID 0 to 1024 onwards.​​

Hi!Could yo tell me some information, where I can find footprint pattern to ASM330LHH device?Thanks for your help!

Hello,I'd like to debug the I2C Master/Slave example located at:..\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\P-NUCLEO-WB55.Nucleo\Examples\I2C\I2C_TwoBoards_AdvComITI have the 2 Nucleo WB55 boards with proper I2C connection, And have a CubeIDE debug environment.Is it possible to open both the Master and Slave projects running on different Nucleo platform simultaneously on the same ST Cube IDE? Is it similar for dual core debugging ?Thanks In Advance,Micha

I'm writing code for the STM32F411 and STM32F103 MCUs using the ST HAL library. The firmware reads an IDR directly using the HAL function HAL_GPIO_Read_Pin. The function is called 2 to 3 times in main(), that is, the IDR register is 'polled' more than once in quick sequence, without an interrupt routine.Problem: not all digital input pins (1s or 0s) are read correctly. The first read access in main() is successful, but 1 to 2 subsequent reads are unreliable.Question: is there a required wait in terms of clock cycles before an IDR can be read again? Or perhaps some reset is needed? Thank you for your responses.
