The  x-nucleo-ihm06a1 board power supply by the MCU (3.3v) and the motor power supply by a DC power supply.The pwm1/pwm2/ref_pwm is generating by the L452 MCU (timer6),the EN/M1/M2/STBY pin connect to the MCU pinout.That can't work.I convert pwm1/pwm2 to spwm,that can't work either.And i can't find any solution in manual.please help me,thanks.

Hi,i develop 100% of my code in my workshop or office, but sometimes i wish i could do some very light modification to a parameter or baud or something in the field and i dont really fancy carrying my expensive workstation laptop around. So i wonder if there is an app for android (or ios) similar to stlink utlity, so i could connect st-link debuger via otg usb to tablet and flash new code(modifing can be done easly in any notepad type app) in the field?

Hello,We have STM8S105K6T6C parts with same COO = Malaysia and same date code but some have MSL listed as 2 on the manufacturing label and the others have 3 as MSL. The question is which MSL is the correct one or they are both correct? I couldn't find any document to indicate what MSL should be. Thank you.

HiI have installed the latest versions of STM32CubeIDE and TouchGFXDesigner. How to set a new program as soon as possible?greetingsAndrzej

Hi,I am using the X-NUCLEO-NFC03A1 board with an Atmega328p MCU and atmel studio.I have been trying to communicate with the CR95HF via SPI but I cant seem to get any reply on the MISO line. The MISO line never drops below a certain voltage level (around 100mV). Any idea what might be causing this? I checked that the SCK, MOSI and CS signals all have good integrity on the CR95HF chip. I have attached a picture of the SCK and MISO signals.Thanks in advance for your help

I'm using a X-NUCLEO-NFC03A1 board with a NRF52 as host controller. I'm able to read/write commands and set the chip to WFE mode with Tag Detection and IRQ pulse as WU sources.Now I'm setting it to hibernate and, as far as I understood from the datasheet, it should go from hibernate to active state only by setting the IRQ_OUT pin to low state, and then I'd be able to read the chip response that should return the WU source as IRQ pulse (0x000108).However, I seem to be unable to use the chip once it's back from hibernate state, and it only works again after I send a RESET command. I found this strange as the startup sequence shows it differently. Is this correct or am I doing something wrong?ps. I also get 0x0000 as a first response from the chip, which is also strange as it is not mapped as a valid response in the datasheet for an IDLE command.

Hello,I've been trying to transfer some data from AXI-SRAM to DTCM via MDMA but it seems not functional.The transfer occurs the flag of end of transfer is set yet the data that I have in my DTCM isn't the orignal one contained in the AXI-SRAM.Also important point to note is that I don't have an error flag.I have reduced everything to a minimum but yet it doesn't seems functional.Here is some bits of my code:#define ADC_IN_BUFFER_SIZE 10   __attribute__ ((section(".axi"), used)) uint16_t RandomBuffer[ADC_IN_BUFFER_SIZE]={0x0000}; __attribute__ ((section(".dtcm"), used)) uint16_t samplingBuffer[ADC_IN_BUFFER_SIZE]={0x0000};       void MX_MDMA_Init(void) { //switching on the clock for MDMA LL_AHB3_GRP1_EnableClock(LL_AHB3_GRP1_PERIPH_MDMA);   NVIC_SetPriority(MDMA_IRQn, NVIC_EncodePriority(NVIC_GetPriorityGrouping(),0, 0)); NVIC_EnableIRQ(MDMA_IRQn);   LL_MDMA_SetTriggerMode(MDMA, LL_MDMA_CHANNEL_0, LL_MDMA_BLOCK_TRANSFER); LL_MDMA_SetRequestMode(MDMA

Hello,I am facing random HardFaults on a STM32F722. They happen at various places in code, sometimes even during stack's initialization.Stack's analysis do not show any risk of overflow : most of the time, the problem happens while executing main() loop, and stack's width is never more than 2 levels.Looking at Fault status Registers shows:_ bit FORCED of HFSR is set to 1_ CFSR = 0x1000000 = bit UNALIGNED of UFSR set to 1: unaligned memory access. bit UNALIGNED_TRAP is set to 0Looking around PC and LR, I only see "unoffensive" instructions (typically, ldr, str, or ldr.b and str.b), and the code registered in stack is part of my main's infinite loop, which most of the time executes without any trouble. So I do not understand how it could sometimes trigger a memory alignment fault...!I read https://community.arm.com/developer/ip-products/processors/f/cortex-m-forum/43707/unable-to-determine-offending-instruction-usage-fault-illegal-unaligned-load-or-store-cortex-m7-keil-mdk

Hi!How to set Gpio pin high while MCU is in deep sleep mode to keep power supply on?I cant find any information.

I need to reload view completely after major external changes. I don't want to reset each state manually.What is the correct way to do this? Is this the only way?void MyView::reloadView() { application().gotoMyScreenNoTransition(); }This works fine, but requires custom handles for each view.

I'm using Dynamicgrapgh widget in TouchGFX to represent the sensor values graphically, i want to display the X and Y axis labels. I'm unable to get the labels on display UI even though i have enables Horizontal and vertical axis labels. Also how to write a function to update the sensor values on graph. Suggest me a solution

Hi I am trying to implement a custom ISO/IEC 15693 command called "Fast Read Unlimited Blocks" command for the Fujitsu Tag MB89R118C (attached the datasheet). This command allows reading all 256 memory block or 2048 bytes on the Tag's memory in one transaction. I have created a function `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited` to implement the Fast Read Unlimited Block Command using the rfal library and the `rfalNfcvPollerTransceiveReq` function call. The implementation and use of `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited` is as follows:Implementation of `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited`:// Fast read multiple blocks unlimitedReturnCode rfalMb89r118cPollerFastReadMultipleBlocksUnlimited(    uint8_t flags, const uint8_t* uid, uint8_t firstBlockNum,    uint8_t numOfBlocks, uint8_t* rxBuf, uint16_t rxBufLen, uint16_t*&nbs

Posted on June 12, 2018 at 10:21I am trying to interface with the ST25R3911B-DISCO board via UART. Basically I want to send commands to the reader and then receive the response via the provided UART. I am planning on connecting the ST25R3911B-DISCO board to an external MCU and thus want to use UART as the interfacing standard between the two.I am struggling to find documentation on on how this is possible via the boards UART. Where can one find out what baud rate to use? And Is there a specific mode in which the ST25R3911B-DISCO board must be in for communication via UART to work? Also what commands are available and what type of responses can be expected from the boards UART.Any documentation, assistance or pointers to help would be greatly appreciated.The tag I have is the stock standard ST25TA64K that came with the ST25R3911B-DISCO kit.#st25r3911b-disco #i2c-and-uart #ndef-st25ta64k

Hello. I have a circuit containing notably: (i) MCU pin PA2 connected to both a ULN2003 transistor-array input and a 10k pulldown resistor and (ii) the corresponding output of the ULN2003 is connected to a small beeper GND. In theory, this circuit is supposed to maintain the transistor input at logical zero when the MCU pin is floating, hence preventing the beeper from ever turning on unless it is desired. I noticed the following:When powering on a board with a MCU that was never flashed, my beeper always turns on. When I check the MCU pin PA2, I read 3.3V. This 3.3V appears despite the 10K pulldown resistor on it, so we can be sure that the pin PA2 at this point must be configured as output, with logical 1 set.If I flash a program that does nothing (simple infinite "for" loop just after the main entry point), then doing a power cycle, the beeper no longer turns on, and the MCU pin now reads 0.If I erase the whole MCU and do a power cycle again, then the beeper turns on.The datasheet f

I have bought the SPC582B-DIS EVB from Mouser. (SPC582B-DIS STMicroelectronics | Mouser Korea, Republic of)However, this product doesn't work normally. I think there is a problem with FDTI Dirver chip as below.So, I asked Mouser for a refund. However, they asked me to confirm from ST that there was a problem with the product. Please, help me for a refund. Thank you.

Hello,I have the RTC set for a 1 Hz interrupt. I have buttons, that when pressed, trigger a rising edge interrupt. The interrupts work fine except that when I call my button handling routine the RTC interrupts are blocked. They remain block until the button is released. I wouldn't thinkit would behave this way for an edge triggered interrupt. Here is the gpio interrupt handler in stm32l0xx_it.c: * @brief This function handles EXTI line 4 to 15 interrupts. */ void EXTI4_15_IRQHandler(void) { /* USER CODE BEGIN EXTI4_15_IRQn 0 */   /* USER CODE END EXTI4_15_IRQn 0 */ HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_9); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_10); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_11); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_12); /* USER CODE BEGIN EXTI4_15_IRQn 1 */   /* USER CODE END EXTI4_15_IRQn 1 */ }These call this handler in stm32l0xxhal_gpio.c * @brief This function handles EXTI interrupt request. * @param GPIO_Pin Specifies the pins connected to the EXTI line. * @retva

Hello,if try to reproduce the STM32H743-EVAL board, is it possible to program its NOR FLASH (MT25TL01GHBB8ESF) if i use the existing external loader? I think the answer is yes. However, i can put in my board just the STM32H743II MCU instead of the STM32H743XI present in the original board.Before i try to do this, will the programmer returns error if i try to program my custom board?

Hello, guys.I need to improve one old project. There is no free pins on MCU left, except PC13-PC15 and I need three external interrupts. Code with initialization for making PC13-PC15 as inputs lower. I do not use LSE or RTC anyway.For PC13 all works fine, interrupt works as desired. In IRQ routine flags are cleared as expected. But after first change of pin state for PC14 or PC15 interrupt keeps fire, as if corresponding pending bits are not cleared in IRQ handler. In project I used StdPeriphLib v.3.5.0. I checked, there is no mistakes on low level acces to registers in functiones and definings of corresponding setting bits. Also there is no external noise on PC14 and PC15. To be sure about this, I've tryde different external "strong pullups", also oscilloscope shows no noises on this pins. VBAT pin externally connected to VDD with a 100nF capacitor, as said in reference manual. Also external impulses are coming with clear fronts, there are no parasitic capacitance or connections on th

How to change background color of the elements that I have selected but later removed that selection in dark theme? If I select CDC_Receive_FS, for example, and it is green in dark theme, after I continue to do anything the background of all instances of CDC_Receive_FS are becoming freaking acid. I can't even read this.Here is a screenshot

I create a project on stm32f429zi nucleo, add LTDC, Touch GFX, CRC. I configure everything, add a BOX and a button. There are 3 errors when compiling. I tried it on different versions of CubeIDE and TouchGFX and different controllers. The only thing is that the errors change. On older versions, there are errors with the stack.make -j8 all Error: Cannot find the specified linker script.

I can successfully program a STM32L082 over USB when using STM32_Programmer_CLI.exe but not using the GUI. I can see the device under USB but I get "Error: Data read failed" followed by "Warning: Connection to device 0x447 is lost" when clicking the connect button. I have previously had no problems using this method on the same board (possibly with an earlier version of STM32 Programmer).

I'm looking for any potential vendors where I could host a cloud VM for doing automated STM32 builds coupled with some infrastructure for managing releases? Any recommendations?

Hello community, I am trying to debug my STM32f103C8T6 bluepill board (probably using fake chip) on STM32CubeIDE but there is something goes wrong about both GDB and Local Server. In debug configuration, When I set debug probe to "ST-Link GDB Server", I got "Failed to start GDB server Error in initializing ST-LINK device."When I set debug probe to "ST-LINK (Open OCD)", I got "localhost:3333: The system tried to join a drive to a directory on a joined drive." I programmed my board on Keilu5 without any problem. Actually I have to press reset button after flashing even I select "reset and run". this is maybe an important issue. Also, debugging on Keilu5 working bugy on my board. I hope this information bring a solution to your mind. System;Windows 10,8 GB RAMIntel i7 6700HQGTX 950m   Regards. Baki ALMACIHacettepe University Electrical and Electronics Engineering.
