Hello, I am currently developing with SPC5Studio 6.0.0.In my project, I need the HighTec Pro option, so I downloaded the license and tool chain files from http://register.hightec-rt.com/st/spc5x.I placed the license file in both:- C:\SPC5Studio-6.0\licenses- C:\HIGHTEC\licensesHowever, it still says that no valid license can be found.How can I resolve this issue?Best regards.

Hi there,I have a new custom PCB with STM32H735IGT6 with Infineon HyperRAM S70KL1283 connected to OCTOSPI2.This RAM device does not use HYPERBUS but xSPI (Octal) interface. It seems to be using a combination of HYPERBUS and regular command SPI mode as protocol.As far as I understand the supported frame formats in the STM32H735 our RAM device is not supported by the OCTOSPI interface.Is that correct?As a solution we have to take the HYPERBUS variant (S70KL1282) of the RAM device.Can anybody confirm my thoughts?Many thanks! 

Hi  I have the cube monitor plugged in , and running the cube monitor power application. I had it working on my old computer (Windows 10) , but had to install the USB driver of ST web site. Since moving to my new computer, I cant find the driver again. Anyone point me to where it will be? My new computer is WIndows 10 too, and installing the cube monitor power application doesnt install the driver Many thanksScott

STM32WB55RG not showing when using STM BLE Toolbox. In fact NO Bluetooth devices are showing at all.When I use the LightBlue app or scan using the Bleak Python library on my laptop, all discoverable devices are showing, including the STM32WB55RG with all its correct advertising data.

Hello Guys,  currently, im trying to get the VL53L0X to work with my MSP430 Controller but my biggest problem is the communication with the Device. Ive copied the Software from Artful Bytes and changed it to match my board. Here is the Link: https://www.artfulbytes.com/mcu-i2c-driver   Ive tried to write a simple byte to the Sensor but all it does is pulling SCL and SDA down right after transmitting the last digit (write). It doesnt even give an ACK and it willbe pulled down until i cut the power supply. Writing Byte Ive also tried to read a byte from the Sensor and strangly it seems work. All i did was to write a simple code to read right from the VL53L0x. There was no init for the Sensor but it didnt pull the line down. Reading Byte I need help with my Sensor. Do i have to write some data to an other Slave-address before writing to 0x29?    Sincerely EddyK

I would like to turn off the backlight if the LCD module of STM32H747I_DISCO board. I figured out that the PJ12 (LCD_BL_CTRL, PORT = J PIN = 12) probably controls the backlight of the LCD module (from schematics). The "PJ12" is initialized in "main.MX_GPIO_Init()" and it is set to output to level low (GPIO_PIN_RESET) during POR.  I tried to set PJ12 to high and low with the follow HAL call:     void Screen1View::handleTickEvent() { if (++tickCount >= ScreenUpdateCount) { tickCount = 0; updateScreen(); if (++lcdBackLightCount >= TurnOffLcdBacklightCount) { lcdBackLightCount = 0; // Turn off LCD HAL_GPIO_WritePin(GPIOJ, LCD_BL_Pin, GPIO_PIN_SET); // HAL_GPIO_WritePin(GPIOJ, LCD_BL_Pin, GPIO_PIN_RESET); } } }       but it did nothing. Backlight of the LCD stays always on. The test app is based on TouchGFX. Any idea? Thanks, Louis

Hello,I'm facing a very annoying issue in CubeIDE.Board: Nucleo-F412ZH.The project uses TIM1 Channel4 to genrate a Stream of PWM pulses to drive a WS2812B LED strip using DMA.It also uses TIM9 to generate the systick.With this configuration, the MCU goes to HardFault in HAL_Init -> HAL_InitTick.The HardFault is triggered when the SysTicvk interrupt is enabled.Digging in the code, I found that the guilty code is in the shared interrupt handler.This handler is invoked by the SysTick interrupt but, due to the interrupt sharing with TIM1 Break interrupt,the handler call HAL_TIM_IRQHandler for TIM1.Digging deeper, I found that the code calls a non existing CallBack function (NULL pointer).At this point of the program, TIM1 is not yet initialized, it will be initialized later in the main function.Here after are the the guilty parts of the generated code.If I remove the line HAL_TIM_IRQHandler(&htim1); all run fine.This issue is not exclusive to the TIM1/TIM9 pairing, it occurs for any

Hello there! I am new to STM32, I have an STM32F746G_DISCO, I have a project where I have to control the frequencies and duty cycles of a machine, that's kind of besides the point, I have set up all the screens I need and I have to make it so that that every value I set (ie: frequencies and duty cycles) to be kept in the memory and not only the screen values should be the same, I also need to have the counters I use on the code (which I will use to determine the signals to control the values, I will make a more detailed post to ask how I will do this)Basically I need these values stay the same even after a screen change, can anyone help me with this?

I used CubeMX 6.12 to generate code and DAC output works as intended.I cloned that project, migrated to CubeMX 6.13 and generated code. DAC output doesn't work. Migration to 6.13 also used FW H5 1.4 instead of 1.3.Comparing stm32h5xx_hal_msp.c I see the 6.13 generated code lacksRCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; if(hdac->Instance==DAC1) { /* USER CODE BEGIN DAC1_MspInit 0 */ /* USER CODE END DAC1_MspInit 0 */ /** Initializes the peripherals clock */ PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_DAC; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK) { Error_Handler(); } }in HAL_DAC_MspInit(). When I add the above code to stm32h5xx_hal_msp.c in the migrated project, DAC output works as expected.No significant differences between the IOC files.Is there a problem with CubeMX 6.13?Attaching STM32H563VIT6_2.ioc (original, CubeMX 6.12, DAC works) and NGC_HW_Verification_Clone.ioc (cloned, CubeMX 6.13, DAC does

Hello,I'm designing a battery powered device with integrated payment terminal. The goal is to pass EMV Level 1 certification.Our approach is very bare metal. We design the board, circuitry and firmware from scratch. No HAL or RFAL is being used. Our own proprietary C++ library for ST MCUs is.For the past few weeks I've struggled with antenna matching so that Analogue Tests for Radio Frequency Power TAB111 pass on all three EMVCo Test PICCs. That's ok now and I believe my system has a proper antenna shape, impedance and Q so that the signal shape is correct.But I'm facing issues with demodulation. In certain conditions an IRQ due to start of receive doesn't occur. Namely when Negative modulation is transmitted by PICC. Or when TEST PICC with High Linear Load is used for testing.When no load is applied, the result of Measure Amplitude is 2.74 V, which is very close to recommended 2.8 V on RFI inputs. The voltage divider appears to be chosen correctly. Even with high load, the Voltage hov

Hi, I am using STM32G0B1x MCU on my custom hardware and using built in FD CAN controller for communication with external CAN 2.0 device. ATA6560/1 is the CAN transceiver chip from Microchip I am using on my custom board. As per datasheet this chip is CAN FD ready.  I have gone through application note AN5348 and also video - https://www.youtube.com/watch?v=xGRvVKfs2-0 for using FDCAN in normal operating mode. It tells me to use kvaser tool to calculate values for parameters for CAN controller settings. I used this tool with following inputs to achieve Nominal and Data bit rate as 125Kbps. My external CAN2.0 device works at 125Kbps. I got calculated parameter values as below: I was able to set values for Nominal parameters but for Data parameters, calculated values are far away out of range and STM32CubeIDE is a not allowing me to set these values. As per calculation, Data SJW = 255 but tool says its value can be between 1 to 16.  Same is issue with Data Time

MCSDK:mdsdk6.3.1 In the decoupling term calculation of the current loop, is there an error? welecT is of the fixp30_t type, while the compensation term uses FIXP_mpy(upQ, welecT). The result obtained in this case should still be Q30. Should FIXP_mpy be changed to FIXP30_mpy?   

Hello,I'm trying to use the USB-HS peripheral with the built-in PHY on Nucleo STM32H7S3L8I'm using CubeMX generated code from CubeIDE. I have not chosen the Nucleo board on CubeMX, because it was causing some issues with the MPU. Instead, I've chosen the MCU (STM32H7S3L8).The peripheral times out during initialization at a usb core soft reset, just after enabling the internal PHY. What am I doing wrong? Has anyone been able to use the USB HS PHY on this device/board.This is the USB_CoreReset call where I am getting a HAL_TIMEOUT:   HAL_StatusTypeDef USB_CoreInit(USB_OTG_GlobalTypeDef *USBx, USB_OTG_CfgTypeDef cfg) { HAL_StatusTypeDef ret; #if defined (USB_OTG_HS) if (USBx == USB_OTG_HS) { if (cfg.phy_itface == USB_OTG_HS_EMBEDDED_PHY) { /* Init The UTMI Interface */ USBx->GUSBCFG &= ~(USB_OTG_GUSBCFG_TSDPS); } /* Reset after a PHY select */ ret = USB_CoreReset(USBx); ...    These are the things in the code which are possibly relev

I'm trying to change from ST25DV16K board to ST25DV64KC and use it.The board setup part seems to be fine, but there's a problem with the interrupt setup part.When writing data to the EEPROM of the tag board with RF from NFC08A1, the code that worked on 16K doesn't work on 64KC. What's the problem?This is my code.int nfc_gpo_it_init(){    int ret = 0;    ST25DV_PASSWD passwd = {.MsbPasswd = 0, .LsbPasswd=0};      if (ST25DV_PresentI2CPassword(&NfcTagObj, passwd) < 0)    {        printf("Error Point1\n");        return -1;    }    ret = Nfctag_Drv->ConfigIT(&NfcTagObj, ST25DV_GPO_ENABLE_MASK | ST25DV_GPO_RFWRITE_MASK);    if(ret != 0)    {        printf("error\n\r");    }    passwd.MsbPasswd = 123;    passwd.LsbPasswd = 123;    if (ST25DV_PresentI2CPassword(&NfcTagObj, passwd) < 0)&nbs

Hello! I've designed a PCB using STM32F407vgt6 but I cannot get it to connect using ST-LINK/V2 via the SWD interface. When I try to connect using STM32 ST-LINK Utility, I get the following error: Can not connect to target!"Connect Under Reset" mode from Target->Settings menu and try again.If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.No target connectedNeither suggestion in the error message solves the issue.I have confirmed the ST-LINK/V2 adapter works because it connects to STM32F407-DISC1, which also uses STM32F407vgt6, using STM32 ST-LINK Utility and ST-LINK/V2 via SWD with no issue.I've confirmed that the SWDIO pins, power, NRST and BOOT0 and BOOT1 are connected correctly per the wiring diagram using a multimeter and inspected all other solder joints and they all look okay. I also tried adding in 10K pullups to 3.3V on SWDIO and SWCKL but it didn't help so they are removed in the picture.

Hello,I am working on a project where I need to read the UID of an NFC tag using the ST25R3916 and communicate via I2C. After powering on, I can successfully read single register, but after setting the device to "Ready mode" by setting bit 7 of the Operation Control Register (0x02), I only read zeros, even when attempting to read the FIFO.
