Hi,I have run the example code STM32Cube_FW_U5_V1.1.1\Projects\B-U585I-IOT02A\Examples\GPIOGPIO_IOToggle_TrustZone and I can no longer connect to the B-U585I-IOT02A board via STM32CubeProgrammer to disable TrustZone. I have the ST-LINK error message (DEV_TARGET_NOT_HALTED).Thank you

I am following this video: https://www.youtube.com/watch?v=aqSNz26Cuio&t=35s Hardware:STM32 Nucleo-32 for STM32L432Adafruit microSDcard adapter: https://www.adafruit.com/product/4682Samsung 32GB EVO (red) microSD cardSoftware:STM32CubeIDEThe board used in the video is different but all the settings are also present in my STM32L432 board.My .ioc pinout view looks like this:Note: In video, the SPI1_SCK has been automatically given to PA5, but for my board it was shown as PA1, hence have made the connections accordingly.FatFS enabled:MAX_SS - 4096USE_LFN - Enabled with static working bufferSPI1 enabled:Mode - Full Duplex - MasterParameter Settings - System Core SYS set to Serial Wire (as shown in video)After following the video, My build is complete with no errors.

Hi,I want to connect a display powered by TouchGFX to a PC via usb-c. Is it possible to allow internet connectivity for a GUI widget via the usb-c connection to the host PC?Thanks!

Parts TOP marking cannot match with factory label Marking for MPN#L9177A-TRPlease help to check the attached picture and let us know what does CB notes on the marking of the chip.

The attached simple project contains an ioc-files where the DFSDM peripheral is configured: channel 0 and channel 1; filter 0 for channel 0 and filter 1 for channel 1. In addition i have configured TIM6; but that's not relevant for the issue. This all is based on a real project; but i have narrowed it down to a minimum because only the code generation process is relevant.The issues are in generated file dfsdm.c in sub folder Src. After generation, the file contains two errors:The code between lines 43 and 67 MUST be executed after line 102. In other words: first the channel must be configured and THEN the filter. This is an old error ... maybe two years old or even more. I don't recall where i have read that the present order is wrong. But in order to make my application work, i need to swap the generated order.The statment "static uint32_t DFSDM1_Init = 0;" occurs twice: in line 119 and in line 175 causing build-error. This is an error which must have been introduced during the last t

Hello.​I use STM32G071GBU6, and I designed the VDD voltage to use 1.8V.​I have some questions on the board.​1. 3.3V GPIO OUTPUT CONTROL- Should I set the GPIO pin of the MCU to open drain and connect it?​​2. 3.3 Volt UART Communication ( TX,RX)- Should I set the UART pin of the MCU to open drain and connect it?​2.5 V GPIO Control- Should I set the GPIO pin with 5 V tolerant as an open drain and connect it?​If the above method is not correct, please suggest a good method.​Thank you.

Im working on stm32f767 project. I designed my board. I want to upload&download my code. First step i need to take backup (download) my code after that creating a file (xml..?) to SD card. Also i want to upload code which in SD card to MCU. How can i do these?

Hello,I thought to use the OCD flag of the L6474 STATUS register to detect the end of the mechanism’s motion when the stepper motor is blocked.But we have some trouble doing this.If the current in the  OCD_TH is less than the current in TVAL, the OCD flag is set at the beginning of the motion.If the current in the  OCD_TH is greater than the current in TVAL, the OCD flag is never set when the motor is blocked.Do you think it is possible to detect when the motor is blocked by using the OCD flag and the OCD_TH register.Thanks for any advices 

Hi, i want to ask regarding the sensor library. As i new to SPC5Studio, i want to connect the displacement sensor. So , do i need to declare the sensor library as a header or just simply can use the ADC header library?

Hello, I am still learning about STM32 and I know that the slashes mean that several ports are bonded to the same pin (e.g. PB7/PB8), but what the square brackets mean in a STM32 pinout? and the dash? thanksBest regards

MCU: STM32WLE5CCIDE: Stm32CubeIDE 1.9.0I have generated a project using MX and thought I'd try the generated function for reading the temperature SYS_GetTemperatureLevel().It seemed to output rubbish so I started digging.SYS_GetTemperatureLevel() calls:ADC_ReadChannels(ADC_CHANNEL_TEMPSENSOR);I didnt really understand the macros in the SYS_GetTemperatureLevel() so I wrote an own function, but it doesnt really matter as the error is visible immitiately in the ADC value without calculations.At room-temperature the result from the ADC_ReadChannels(ADC_CHANNEL_TEMPSENSOR); should be close to the calibration value at 30C, but it isnt.I Wrote the following test-code to see the intermediate calculations more clearly.I noted that I started getting sane values (see comments in code) when single-stepping the code and after a while I isolated it to that a 2-3 seconds (!!!) delay between ADC_Enable() and LL_ADC_REG_StartConversion()Seemed to give much saner values (see comments below).It is like

(Environment)MC_SDK 5.Y.3 + STM32CubeMX 6.3.0 with HAL + IAR EWARM 8.5(Hardware)custom board based on F446RE + custom power board(3-shunt) + Low Voltage BLDC motor with Encoder(Control Mode)Speed Control(What I found)In "parameters_conversion.h", there is defined MAX_MODULE as follows:=================================================/* MMI Table Motor 1 MAX_MODULATION_100_PER_CENT */#define MAX_MODULE 32767=================================================If this 100% modulation is used, there might be some moments where low-side duty becomes close to zero (less than dead time). Then the boot capacitors might not be charged properly.Is this value still good as is or need to be modified? If modified, what would be the recommended value?And can it directly modified in "parameters_conversion.h" or by workbench tools?

In the documentation, the file described is generated by IAR embedded workbench. I'm using cubeIDE. Where can I find the mapping file?

I am expecting an answer from an ISO14443-2 Tag with no CRC set, so I want to disable that check. Currently I am doing a rfalTransceive with the following flags ( (uint32_t)RFAL_TXRX_FLAGS_CRC_TX_AUTO | (uint32_t)RFAL_TXRX_FLAGS_NFCIP1_OFF | (uint32_t)RFAL_TXRX_FLAGS_AGC_ON | (uint32_t)RFAL_TXRX_FLAGS_PAR_TX_AUTO | (uint32_t)RFAL_TXRX_FLAGS_NFCV_FLAG_AUTO \            | (uint32_t)RFAL_TXRX_FLAGS_CRC_RX_MANUAL | (uint32_t)RFAL_TXRX_FLAGS_CRC_RX_KEEP | (uint32_t)RFAL_TXRX_FLAGS_PAR_RX_REMV)As a result I get a return value of ERR_CRC but also the expected length and data inside my provided response Memory. Is this expected behavior and I should just ignore the error code or is there a different flag I should use?

HelloI'm using a stm32L431 with an STLinkV3https://www.st.com/en/microcontrollers-microprocessors/stm32l4x1.html#documentationHSI is enabled at 16MHz for USART2, used to receive a 1200Bd signal.I receive wrong characters because of the trim.I understood the principle of trim and its registers, in particular thanks to this docdm00425536-how-to-optimize-stm32-mcus-internal-rc-oscillator-accuracy-stmicroelectronics-2.pdfMy question: is there a way to adjust this trim automatically via cubeIDE and stlinkV3?Maybe another solution less practical but more practical than a manual adjustment?Thanks in advance
