 Hi,1. Project Purpose:  Generate pulse to control stepper Driver. 2. My method and step:  1) every 2 milisecond calculate out the pulse need to send next cycle;  2) DMA and Timer Handle the pulse sending.      a. Timer update interru  3pte cycle is 2ms,  ARR = 56000.      b. enable OC compare output , Toggle mode      C. Timer count from 0~56000, CCRx will be a series value attempt to toggle the output.          For example, I want to generate 2 pulse in 2ms cycle, Then I need to set CCRx to  14000 , 28000, 42000, 55999 step by step.       d. Using DMA to Send CCRx Array.       e. Using DMA Double Buffer mode. 3. My Question:    1)  All work right when the pulse frequence below 100kHz    2)  It seems that above 100KHz, DMA will be too slow to push the newer CCRx value to the peripherial. So th

Hi,I want to debug the H753ZI through USART2 and connect to the PC through USB. I've done this a lot with other NUCLEO boards. Apparently this feature is not present on the H753ZI board?Is there another UART connected to the ST-link on this board? Or is there no opportunity to send UART through USB?Thanks in advance,Best regardsTom

Hello, Where I can get the Altium files for the X-Nucleo-NFC08A1?

I'm using STM32CubeProgrammer to flash my custom target using an STM32MP153AAA MPU. I have onboard a 4GB eMMC memory. During the programming process through DFU all seems good and finishes at 100% but then sits for a bit and I get errors. Seemingly TF-A is crashing or not starting after load. I'm searching for causes and how to fix. Attached is my TSV file using in the programmer. I'm using EcoSystem 4.1.0.

I want to design an Intuitive System with a 1280x 800 LCD interface with RGB 888 running Fluidic Animations and transitions (30FPS) Which system combination will work to create such a system? I figured it would require STM32H750 Or similar MCu with 32 BIT RAM Interface 24 Bits RGB Along with QUAD FLASH.

MCU: STM32G491RET6 Due to other pins being unavailable, I am trying to use TIM8_CH3N to generate a PWM output. To test this, I used CubeMx to generate configuration code for me, and only added the line to start PWM:HAL_TIM_PWM_Start(&htim8, TIM_CHANNEL_3); // start pwm generationTo check that the MCU and CubeMx code are good, I also am generating another PWM, on TIM3_CH1. Again, I only added one line to the CubeMx generated code: HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_1); // start pwm generation TIM3_CH1 PWM works, while TIM8_CH3N does not. I am not sure if it is possible to use only TIM8_CH3N, without using TIM8_CH3 (I can't use TIM8_CH3 because the pin it is connected to has another dedicated function).Any help appreciated.Code: main.c:  main.c: /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************

Hello everyone,I working with the X-Nucleo-NFC08A1 and the X-Cube-NFC6. I would like to know at what point in the program is the RF field turned on. The reason for this is that I would like to know how long a Tag has to be in the field to be ready for action.Rgds

With reference to RM0436, the STM32MP157 Reference Manual, revision 6.On pages 1066 and 1072 the schematic structures of a GPIO port are drawn (figures 119, 120, and 122). These all show an inverter circle on the gate of P-MOS output transistor and none on the N-MOS transistor. This suggests that the P-MOS is active low and the N-MOS is active high.However, the written documentation states the opposite: that the P-MOS is active high (pulls the output pin high for a "1" bit unless in open-drain mode) and the the N-MOS is active low (pulls the output pin low for a "0" bit).From experience I believe that the written documentation is correct, so should the schematic not be redrawn to show the inverter circle on the gate of the N-MOS output transistor?Attached please find annoted screen shots of the pages in question.

The above is my schematic layout of ,STM32F103C6 Series, attached to a virtual terminal with transmitting and receiving lines mentioned and the pin PA2 is used as an ADC input pin.The above is the power rails configuration .The above is the pinout view where PA9 and PA10 are used for transmitting and receiving which are attached to the virtual terminal as showed.The above is the code where I declared test as an unsigned integer of 16 bits and character msg of length 10.Then I have written the code for starting the ADC and then stopping for Conversion whereafter I have retrieved the values from HAL_ADC_GetValue and transmited to the virtual monitor by the help of UART Transmit functionThen I have build my program and converted into hex file whereafter I copied its path to the proteus stm32 model's program file.The above is the output I am getting.I am very confused on what went wrong in my program and simulation,It would be very helpful If you guyz could assist me on this issue.

Hi,What error on HSE frequency is acceptable by STM32WB35? More than 1 kHz can disturb connection process (its interrupted or it's slow than usual on some phones) or can cause unexpected disconnection? Does this affect the range of the advertisement ?Best,msemegen 

Hello, I'm trying to enable the dark theme in SPC5Studio, which Eclipse has by default. See the image. Has anyone got it working? Thank you for your response.MJ.

Hi,looking in the AN5902 Finite State Machine application note for LIS2DUXS12, rev 3 on page 47, it is mentioned that using the Adaptive self-configuration (ASC) it is possible to switch from Ultra Low Power mode to High-Performance mode. However, in the AN58012 application note for LIS2DUXS12, rev 3 page 15, it says that it is not possible to directly switch from Ultra Low Power mode to High-Performance without setting the accelerometer to power-down mode.What is correct, is the ASC example in the AN5902 application note really possible to do? Also, a second question. If TI3 = 125 samples and the ODR is 100Hz, wouldn't that mean 1.25s? In the example it says 5 seconds but that will only be true if ODR is 25Hz, right?  

How to turn on  stm32f429-disc1 board by using an external power supply and use stlink only for programming and debugging.

Hello all,I would like to use the ST Bootloader which is described in the Application Note AN2606.https://www.st.com/resource/en/application_note/an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdf.The used controller is the STM32H563. Under point 50.1 it is described that FDCAN1 must be used. As FDCAN1_Rx pin PB5 and FDCAN1_Tx pin PB13 is defined. But these two GPIOs go to FDCAN2 and not to FDCAN1.Can you help me further on this, which pins or which FDCANx should be used?Thanks in advance!Jannik

Hello!I am trying to run the BLE_TransparentMode example https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/STM32WB5MM-DK/Applications/BLE/BLE_TransparentMode/STM32CubeIDE I have opened the project in STM32CubeIDE and try to compile,I get errors that the stm32wbxx.hfile is missing, which is true, its not there. I have searched the whole STM32CubeWB github directory for this file but its not there, although there is a folder STM32WBxx at STM32CubeWB-master\Drivers\CMSIS\Device\STbut that folder is empty. Am I missing something?

Hello,I am using the X-Nucleo-NFC03A1 shield with the Arduino Uno. I use the library for the BM019 as an inspiration for reading my tag. Setting the protocol, the echo command and the IDN command all work fine, but when I try to read the UID of the tag I always get the error 88 in my response code meaning invald start of frame. I am using the ISO 15693. Could you help me find the cause of that error and tell me what it means.For getting the UID I use the commands 0x00 0x04 0x03 0x26 0x01 0x00 as reccomended in the datasheet.Thanks. 

Hello.I would like to know about the error of TSB582 consumption current.Please let me know if there is a figure between it's consumption current (or quiescent current) vs. supply voltage for the number of parts, and data on minimum and maximum consumption current.Thanks.

Hi, Our team was working on training Deep Learning models for a specific business requirement. We ran into an issue with our training data as it's biased toward our region (as we collected local data). Does ST offer Data Collection services that can help us obtain the required data? We don't want to go with third party data providers (unless they're partnered with ST).

Hello everyone,I have not conventional question. My purpose is to create code where 2 pins are used as two different interfaces (I2C1 and USART3). I know that pin Stacking option is just theoretical as no code is generated for this interface. I found solution to it as I: 1. Generated normal code for I2C so it works normal2. defined huart3 struct and mx_UART3_Init all in user code brackets in usat.c /usatr.h the same as it would be generated from ioc file.3. Code in fucntion HAL_UART_MspInit and HAL_UART_MspDeInit is generated only for one instance USART1 (My debug uart). So i added "else if" for USART3 instance as if it would be generated by cube. The trouble here is that user code bracket is only inside the "if(instance ==USART1)" And here is my problem code is working fine, trouble is this that every time i change something in ioc file my code from third point is deleted so i need to take care of it and add again my changes. Is there any way to stop cube from changing

Hi all,I'm using stm32l431 and met a problem as below.After power up a new stm32l431 board which had not been programmed before, the MCU enter bootloader progam and the PC value is 0x1FFF xxxx.  Downlaod my own code to MCU but the code and not run.Then, erase the MCU flash by "STM32Cube progammer", the MCU can work.BTW, boot0 and RESET pin connect correctly.

I am using STM32H747 Discovery kit. Using FreeRTOS, trying to understand if SysTick->VAL  is it in Micro-second?

I need 1.5 MSPS speed for my array device having 1536 pixels. I saw that the STM32WB55VGY6TR microcontroller operates its ADC at a maximum speed of 4.26 MSPS in the manual. So, my question is, if I activate 16 channels (the maximum number of channels of this microcontroller), what would be the maximum MSPS? It should be 4.26/16 MSPS? or same?

[VERSION]: MCSDK 6.2.0，STM32CubeMX 6.9.2[TOOL]: MotorControl Workbench 6.2.0[DETAILS]: I want to add my custom control board,but it say "Unable to generate ioc file due to: The following has evaluated to null or missing".My custom control board is STM32F405RGT6, but my attempt failed. Then I try STM32F401RDTx, it is same.1.create mcu json (STM32F401RDTx), copy from STM32F401RETx.json.I have to add an MCU that is not in the list, otherwise my custom control board will not be displayed correctly.   Then in this STM32F401RDTx.json file, I replace "STM32F401RETx"  with "STM32F401RDTx" , and change the flash size to "flash" : 384.  The two are just different in flash size, I think it works fine.2.Create new board using Board Manager.  Clone from NUCLEO-F401RE.Then change the mcu name.3.Create new projectSTM32F401RD+IHM17M1Then generate the project. I want to know how to solve this problem.

Hi there!First time on the community, but have been programming with STM32s for some time now. I am currently facing a speed challenge using the HAL_SPI_Transmit() function. In order to toggle the CS line, I have always done something along the lines of:HAL_GPIO_WritePin(GPIOA, GPIO_PIN_15, 0);HAL_SPI_Transmit(&hspi1, bufSPI, 2, 200);HAL_GPIO_WritePin(GPIOA, GPIO_PIN_15, 1);This has never given me any issues and always executed in a reasonable time frame. I recently migrated a project from STM32L152 to the STM32L071. Based on the datasheets, I understand there could be a roughly 30% speed decrease even with both running their system clocks at 32 MHz. However, this seems to have translated into a very large overhead on my SPI transactions (a lot more than 30%). What I am looking to see is if there is either a way to get the SPI driver to handle my CS line for me, or somehow reduce the overhead associated with a call to the HAL (I am not afraid to modify or bypass the HAL functi

This seems like an easy one, but I've searched high and low.  Both STM32CubeMX (v6.9.2)  and STM32CubeIDE (v1.13.2) place generated code in a root folder named Core.  Is there a way to configure file placement into folders of my choice?
