Hello, I have recently upgradated STM32CubeIDE from v.1.13.2 to v.1.14.0.The upgrade seems has gone well, as indicated in the Help->About window:Anyway, if i check the window installed application list, is still indicated the previous version:Also, in the file system I continue to see the old version 1.13.2, but not the new one 1.14.0.This doesn't seem to be very clear and I am a little bit confused.Is it better to disinstall a reinstall STM32CubeIDE?Regards,Carlo 

I'm starting a project using the STM32WL55JCI7 chip, but I'm getting the following error. How do I fix this?An error occurs when compiling with IPCC Activated checkedDescription Resource Path Location Type'IPCC_C2_RX_C2_TX_IRQn' undeclared (first use in this function); did you mean 'IPCC_C1_TX_IRQn'? ipcc.c /STM32WL55JCI7_CM0PLUS/Core/Src line 63 C/C++ Problem

Post edited by ST moderator to be inline with the community rules especially with the code sharing. 1- In next time please use </> button to paste your code. Please read this post: How to insert source code. 2- Post is not related to CubeIDE usage but more to the product so it needs to be moved to "STM32 MCUs Products" forum. So please don't post your question in CubeIDE only if it's related to CubeIDE usage or to raise a limitation in it.   I have a 110k resistor in series with a 110k thermistor as well, at the midpoint I connect PC0, the other leg of the thermistor to 3.3v,  the sConfig.SamplingTime is 247.5.  But the readings are 110 Celsius when it should read 22 Celsius, what am I doing wrong,  this is my code, thanks define R_SERIE 115000.0f // resistor fijo del divisor #define BETA 3950.0f // coef. beta del NTC #define T0 298.15f // 25 °C en Kelvin #define R0 115000.0f // resistencia nominal NTC a 25°C ADC_HandleTypeDef hadc1; volatile uint16_t adc_va

I tried to search the forum so I'm sorry if there is a solution posted to this problem.I have been struggling with creating the pattern inside the image. Every 10 seconds I want a short heartbeat pulse generated by DAC. (DAC goes high, then low).The period can experience a bit of jitter, no problem, but ideally it's every 10 seconds. However, the pulse is very important to have the correct timing as it is not allowed to be longer. I have tried to drive a timer in OPM mode with a slower timer as trigger, and the timers worked, but I couldn't get DAC and DMA to function the way I wanted, if this approach is possible, configuration pointers would be appreciated.I have also tried to enable a timer in software and disable it on DAC DMA complete transfer interrupt but this didn't work too well. If there is any way I can toggle the DAC with help of a timers capture compare that would be great. Then I could just enable the timer on some sys tick interrupt, use two CC's and disable it

Where can I find the pinout of NUCLEO H533RE?

I am working with an STM32N6 microcontroller and need clarification about the electrical characteristics of its GPIO pins. How much current a GPIO can source and sink. Is it in micro Amps or mili Amps.

Hi, I am asking about the STM32 usb power delivery middleware. Is there a way to delay/stop the PS_RDY (power supply ready) message from being sent out, or is that completely automatic? Thank you.

Hi,We are trying to mount the VL537CX ToF(Pololu) sensor on roof of a car and map a certain area of the cabin. The sensor is pointed downwards.But we are observing the a pattern flashing (appearing for a single frame of ToF data) at an interval varying from 0.2 to 5 seconds. The pattern is not constant, there will be slight changes each time.There are textured hard plastic surfaces (black color & white color) in the locations corresponding to  the zones where flashing occurs. The windshield is close to the sensor, but is out of its FoV.­­­­­­What could be the reason for this behavior? What can be done to avoid this flashing behavior?Attached the images of normal zone values and zone values during flashing for reference.

I need help identifying a particular ST SOIC 8 op amp. It has the markings: 204/ 9125   I hope to hear back from you as I am interested in this op amp but I cannot find out what it is.

Hi,for a project we are evaluating we need to read bank/credit card data via NFC (Number, expire date, ccv/cvv) to record when people are accessing a gate and when are leaving; similar to the underground gateways that could be accessed with credit cards directly.Could we do it with any of the ST25 NFC readers (e.g. ST25R3916B)?As we do not have to process any payments could we get the credit card data simply using the reader functionalities or do we need any additional software components? (Beside the rfal middleware). Kind Regards,Andrea

Hello,We have a custom board based mainly on stm32mp257-dk design. The sdcard supply voltage doesn't activate on STPMIC for some reason. Is the stpmic preprogrammed on the DK board or should the Rom code of the MPU activate it via I2C? Best RegardsRaimo

Hi,We are using the STM32WLE5JCI6.In our design, the TCXO (HSE) is powered directly by the 3.3 V on-board power supply, and the VDD_TCXO pin is left unconnected. Is this acceptable?Should we avoid using the Set_TcxoMode command in this case?Thanks for any help

Hi.I'm in progress of making an iOS app that needs to send custom commands to a ST25DV tag. I've been going through the same error all week (Feature not supported, from CoreNFC), so I started using the ST25SDKiOS but I still don't get how to use it. I was wondering if there is any instruction to use it to send custom commands to the tag.Thanks.

Hello,I had generated an External QSPI loader for W25Q128JV and STM32H743 some 2 years ago.I originally used it with STlink Utility Programmer and then switched to STM32CubeProgrammer.  All good and working as expected with CubeProgrammer v2.17.I stopped updating the CubeProgrammer as every version after that including the latest v2.20 no longer functional with my custom .stldr file refusing to mass erase the device. Does anyone know what changed in CubeProgrammer support for External Loaders starting with v2.18 ?Thank you,Yuri

I have a custom board with a 1024x600 display. It works fine.Some demo examples only work in lower resolution. I want to get those to work on my display.I was able to trick TouchGFX Designer to think lower resolutions are supported by changing AvailableResolutions in ApplicationTemplate.touchgfx.part. This sort of works, but you see some objects out of the window. It's wasted rendering time too.By changing pLayerCfg.ImageHeight of the LTDC I was able to get lower vertical resolution work. For instance 1024x300. This way the bottom half is black. Which is good.However, when I change pLayerCfg.ImageWidth to 800 I get garbage. I I set it to 1022 the image is skewed. I also played with pLayerCfg.WindowX0 and pLayerCfg.WindowX1, but it doesn't seem to do anything. #include "ltdc.h" /* USER CODE BEGIN 0 */ #include <gui_generated/common/SimConstants.hpp> /* USER CODE END 0 */ LTDC_HandleTypeDef hltdc; /* LTDC init function */ void MX_LTDC_Init(void) { /* USER CODE BEGIN LTDC_

I have a question about configuring pin D1 for UART1 TX (in conjunction with pin E2, UART1 RX).Pin D1 has the option for PA11, [PA9], PA8Pin E2 has the option for PA12, [PA10], PA71. To use pin D1 for UART1 TX, PA11 must be switched to PA9 (SYSCFG_CFGR1: PA11_RMP: = 1).2. To use pin E2 as PA12, E2 (PA7 default) must be switched to PA12 (SYSCFG_CFGR3: PINMUX4[1:0] = 1).3. To use pin E2 for UART1 RX, PA12 must be switched to PA10 (SYSCFG_CFGR1: PA12_RMP: = 1). Question:What is the default setting for pin D1 (PA11 or PA8)? How is PA11 bound to pin D1? I am missing a setting like (2.) for pin D1. I could not find anything in the manual.When I configure this setting with STM32CubeMX, the following code is generated:HAL_SYSCFG_EnableRemap(SYSCFG_REMAP_PA11); // (1.) HAL_SYSCFG_EnableRemap(SYSCFG_REMAP_PA12); // (3.) HAL_SYSCFG_SetPinBinding(HAL_BIND_WLCSP12_PINE2_PA12); // (2.)Where is the binding for pin D1? Many thanks in advance.Dirk    

Hi all,I am a newer STM32 programmer, and I have been working on the STM32H745 Discovery board for the last few months. Something that I would like to do is be able to switch into USB DFU Mode within a UI that I have made for this board. I took inspiration from this post and changed the address to the appropriate one for the STM32H745. I would like to prerequisite that the USB port is initially configured as a VCP/CDC device. Here is the code that I have:void (*SysMemBootJump) (void); void USB_BootloaderInit() { volatile uint32_t addr = 0x1FFF9800; //from AN2606 __disable_irq(); // Reset USB OTG_FS // Disable caches SCB_DisableICache(); SCB_DisableDCache(); // Remap vector table HAL_RCC_DeInit(); //Reset the system clock SysTick->CTRL = 0; //Reset the SysTick Timer SysTick->LOAD = 0; SysTick->VAL = 0; SysMemBootJump = (void (*)(void)) (*((uint32_t *)(addr + 4))); //Point the PC to the System Memory reset vector __set_MSP(*(uint32_t *)addr); //Set the M

Hi, I'm trying to configure an STM32H753 FDCAN peripheral to be compatible with both CAN-FD & CAN 2.0 frames, in both the Tx & Rx directions.   How should I configure the FD-CAN peripheral to achieve this? I've been through he RM0433 document as best I can and am struggling to find this information.

I am trying to connect the custom board to the mems studio to measure the euler angles and to explore the mems studio? is it possible to connect the custom board?

When we use 3920B to read the M1 card, the data sent to 3920B by MCU is "60 3C 1A 80", but compared with the data sent by 3920B captured by equipment, it is found that there are two more bytes "00 00" behind the data sent by 3920B. The difference is shown in the attached picture. Why does the data sent by 3920B have two more bytes? Will this extra byte affect the total length of bytes sent?Use the rfalNfcDataExchangeStart () function to send data, but only the interruption of sending data is completed, and there is no interruption of receiving data, so it has been circulating in do while. The card did not reply to the data sent by 3920B. Is this phenomenon related to the abnormality of the data sent by 3920B?

Hi,The example for FSBL works as describedhttps://community.st.com/t5/stm32-mcus/how-to-configure-the-linked-list-mode-in-stm32cubemx/ta-p/693779But if the same approach is applied to Appli (Secure) code, the "User Setting Error" raised in DMA IRQ.I use the XIP configuration.Could you please elaborate chages to be made in Secure code? 

Hi,I have a custom developed stm32 project with stm32f411ret6 mcu, i have done my full board and got the pcb printed. I have a 4 pin header on my pcb with vcc,gnd, swdio, swclk for uploading the bootloader for the first time. I have done this several time earlier successfully with stlink/v2 programmer, but now it shows the error(image 3 at bottom): Next I bought a stm32f446 nucleo board and tried with the onboard stlink by removing both the jumpers to program this mcu on the custom pcb, still stlink does not connect.  On my pcb header 3.3v power is also coming successfully I have checked it too.    Also, my boot pin and nrst is connected on custom pcb like this:  under both stlink connection methods i am getting this error, trying to solve these for many days and getting the same connection issue as follows, please help me,
