Hello everyone! I'm a novice and I've never used an STMicroelectronics component before.I just downloaded the ST BLE Sensor application to connect to my SensorTile.Box Pro. It recognizes it and everything seems fine so far. I also noticed that there's an option to connect it to a Mosquitto broker, so I entered the URL, port, username, and password, also selecting the features it should send. I noticed that the topic is deviceid/Features, so I created a new node on Node-RED to visualize the data. The app ST BLE Sensor tells me that the connection to the broker was successful, but I'm not seeing any data on the dashboard. Can anyone provide me with some further clarification?Thanks :)

Hello everyone!I would like to ask you for some advice on how to configure the STEVAL-WLC38RX board in the WPSTUDIO GUI so that it receives 5W power.The STEVAL-WLC38RX board is placed on the STEVAL-WBC86TX at the distance shown in the photo. I would like to obtain 5W power to simulate wireless charging of a smartphone for example.I am supplying the board with 8V (WBC86TX) and I have connected a 5 ohm resistor between VOUT and GND of WLC38RX. In addition, I wanted to know if it is possible to display the power received by STEVAL-WLC38RX via the CHARTS of WPSTUDIO, as on the receive side there is nothing unlike on the transmit side.Via the GUI I can only graph the trends of RX PWR and TX PWR on the transmission side. Is this normal? Thanks for your help   

Hi,I am trying to implement STemWin v5.22 for an F4 MCU. I made sure to provide a path to the static library and included all the other necessary files. However I still get this error:../Lib\lib_STemWin522_CM4_GCC.a(GUI_Core.o): In function `GUI__Config': GUI_Core.c:(.text.GUI__Config+0xc): undefined reference to `GUI_X_Config' collect2.exe: error: ld returned 1 exit statusGUI_X_Config is defined in GUI.h of the STemWin library, to which there is a path provided.I don't really understand why there is still an unresolved dependency. Are there other files necessary for this STemWin version? I only got the static library from some online repo, not the official ST website. I don't think this version of STemWin is available anymore

I am using the latest version of the STM32CubeProgrammer (v2.16.0) and am connected to a STM32F405RGT6 via an ST-LINK/V2.The problem is finding the nBoot0 and nBoot1 settings under the Option bytes tab in the software. Does anyone know where I can find this? I have seen other people having these settings under the User configuration but I dont seem to have does. See image.Thank you.

In the STM32CubeIDE I have several yellow triangle warnings. I have read in some other posts this is just that some features of that cannot be enabled due to your current settings. However, in my case I have very many and on all Timers. I am struggling with the UART connectivity and maybe thought these triangles could cause it. See image below: Thank you

 I hope this message finds you well. I am reaching out regarding an urgent matter with my STM32 CubeMX v6.1 project. I have encountered an issue with the I2C functionality that I cannot seem to resolve despite trying various approaches.The specific problem arises with the following function: I have attempted to implement this function across different STM microcontroller units, including STM32WB10, STM32F750, and STM32F103, but unfortunately, the issue persists consistently across all of them. It's worth noting that I have verified the hardware compatibility by successfully testing it with Arduino and ESP32 platforms.Given that I have a project deadline looming, I urgently require your assistance in resolving this matter. Any guidance or insights you can provide would be greatly appreciated.Thank you very much for your prompt attention to this matter. I look forward to your response.

I'm encountering an issue with NFC functionality on iOS, specifically related to reading multiple areas. I have an NFC tag that stores data across three distinct memory areas. Using an Android device, I can effortlessly access all three areas with just one tap. However, when attempting the same on iOS, I receive a message stating, "Read of several areas or capacity limit: not yet managed." I'm curious to know if this limitation is inherent to iOS or if it's a feature that hasn't been implemented in your test app. Thank you in advance for your assistance

All:Setup - STM32H723 with VREFP = 3.00 VI have connected internal temperature to ADC3, and I am able to display degrees C on "Live Expressions". With VREFP set to 3.00 V, I am seeing lower readings than ambient. Using __HAL_ADC_CALC_TEMPERATURE( ), I am seeing internal temperatures of 21 - 24 C, vs. ambient temperature of 25.8 C.Is there a variation based on VREFP? (Earlier on Nucleo board, I was seeing internal temperature of 30 C with VREFP of 3.3 volts.)Regards,Todd Anderson 

Hello,I have made a custom RFID reader board design which is similar to the X-NUCLEO-NFC08A1. However, it powers antennas in single ended mode with a cable through a u.fl connection. I am running the example code for the X-NUCLEO-NFC08A1 on this custom reader and it is not working. How would I get it to work? The code seems to be running fine on the arduino IDE however the TX pin is not lighting up at all, suggesting that a reader field is not being generated. I suspect the reason for this is that the (#define ST25R3916_REG_IO_CONF1_single   (1U<<7))  register in the st25r3916_com.h file needs to be changed from differential to single ended however I don't know how to do this. Help would be appreciated.Thanks,William

I am using MX25 NOR flash memory 256Mbit (https://www.mxic.com.tw/en-us/products/NOR-Flash/Serial-NOR-Flash/Pages/spec.aspx?p=MX25L25645G&m=Serial%20NOR%20Flash&n=PM2075#Technical-Documents) and I am mounting a littleFS file system on it. The memory communicates through SPI with an STM32L562 microcontroller. After writting and reading files multiple times (more than 100) I get a hard fault. MX25_CMD.c is provided by the memory manufacturer and calls HAL_SPI_Receive(). It seems that the hard fault occurs in SPI_WaitFifoStateUntilTimeout().I am really blocked by this issue and I don't know towards which direction to look for solutions. Does anybody have any suggestions? The function calls (from recent to older) before the hard fault:SPI_WaitFifoStateUntilTimeout() at stm32l5xx_hal_spi.c:3’989 0x80338f6SPI_EndRxTxTransaction() at stm32l5xx_hal_spi.c:4’101 0x8033ae2HAL_SPI_TransmitReceive() at stm32l5xx_hal_spi.c:1’535 0x8033566HAL_SPI_Receive() at stm32l5xx_hal_spi.c:1’020 0x

Hey there,i want to reach my flash memory through UART. I can do this with ST-Link device but now i want to do it with UART. I use STM32F091CC MCU and as datasheet says i configured the UART pins(PA9-PA10) as Asynchronus UART in CubeMX.My baud rate is 9600 bits/s- word legth 8bits - parity - even and stop bit is 1.In boot mode configuration. I try to use all configurations but i cannot reach the flash memory.I coded all options(set and clear bitss) in main.c program and when i click connect button in cube programmer it gives me an error like that:Please help me how to solve this problem.

Hello guys!I'm using USB custom HID on STM32G0B for an application alike the mouse demo on "STM32G0C1E-EV" HAL package. But instead a button sending the Report, a PC software sends a 64 bytes Report to get another 64 bytes as answer.In fact, this same code worked flawless on STM32H750 but on G0, I'm always getting a "loopback" answer after "USBD_HID_SendReport()" function, with some garbage bytes. I'm suspicious of the "USB_WritePMA" function, as it put a byte pointer to word buffer...Do you guys have any tip about this?Thanks again!

Hi, I'm interested in using Timer 1 on my STM32F439ZI to decode the quadrature signal from an encoder but TIM1->CNT doesn't appear to change. I'm not sure what is missing, the TIM1 config looks like: static void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init 0 */ TIM_Encoder_InitTypeDef sConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM1_Init 1 */ /* USER CODE END TIM1_Init 1 */ htim1.Instance = TIM1; htim1.Init.Prescaler = 0; htim1.Init.CounterMode = TIM_COUNTERMODE_UP; htim1.Init.Period = 65535; htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim1.Init.RepetitionCounter = 0; htim1.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE; sConfig.EncoderMode = TIM_ENCODERMODE_TI1; sConfig.IC1Polarity = TIM_ICPOLARITY_RISING; sConfig.IC1Selection = TIM_ICSELECTION_DIRECTTI; sConfig.IC1Prescaler = TIM_ICPSC_DIV1; sConfig.IC1Filter = 10; sConfig.IC2Polarity = TIM_ICPOLARITY_RISING; sConfig

Hi, In my application, I'm using SPI (SPI1, a full feature set instance) with CRC enabled, on STM32H563ZI, with the configuration as:I have a CRC implemented based on CCIT standard, which I call 'software CRC'I see different CRC values for the same bytes of input from the micro and software CRC. Fig1. Software CRC which is 0x8B2C (the last 2 bytes shown in Logic Analyzer, with msb first configuration)Fig2: CRC from ST which is 0x5D0C for the same input.My software CRC calculation is not wrong and is verified using this calculator (https://crccalc.com/) which yields 0x8B2C. Kindly help in understanding why the 'hardware' CRC is different from 'software'.   

Many customer face dongle driver issues, most because Unable to load DLL 'HidDongle.dll'.  @sjones i post your request in the forum. Key points: This eval board has an on board FT260, which should take care of the I2C to USB (HID) interface without a dongle The FT260 doc by FTDIchip says: The FT260 is a full speed USB device which supports I²C and UART communication throughstandard USB HID interfaces. The USB HID class is natively supported by most operating systems.A custom driver is not required to be installed for the FT260 So drivers should not be needed.

Hello, I am trying to understand how and in which order exactly events are dispatched to drawables in the draw tree. I was not able to find any information regarding this topic on the touchgfx documentation website. I have two use cases for which this would be relevant:1. I have a scroll list of custom containers which contain several clickable items. Drag events on the scroll list are intercepted by the touch areas of the clickable items. This makes the scroll list difficult to scroll as you have to hit the tiny spaces in between the clickables for the drag event to register.I saw two posts on this forum regarding a similar problem:Thread 1 Thread 2 The accepted answers in both of them did not fix my problem as my application does not allow me to override the touch handling on the view level. The answer given by @GMeur in thread 2 was closer to what i was looking for but only works for me when the scroll list template object itself is clickable. In my case only the chil

Dear All,I am developing an application on the STM32F746 that uses TouchGFX. I am able to load some images from my SD card to the primary cache and I am able to display the images individually on the screen. But when I try to display them together I am struggling. One of the images has unknown size at compile time, since it is loaded from the SD card.This is what does my screen look like in the TouchGFX designer:Both DynamicBackground and DynamicIcon_1 use the same configuration:At times, in my application I need to be able to show one of them or both of them. The location of the image is supposed to be passed by the application.What I am experiencing is that if I try to draw one image, while the other is already being drawn, I am getting a hardfault at this point:From what I have seen so far, if I set the alpha of each image less than 255, then I am not experiencing this issue.But I am trying to understand why does this happen and if there is a fix that does not require to change the

Hi,when I write 8byte block sequentially 256 times in 2kB page and then erase and start over what is the total number of writes I can do?Datasheet describes 10000 write/erase cycles, but I do not erase after every write.If the damage is cause by erase should the flash last longer with 1 erase per 256 writes?can I write 256 times before erase is necessary or it would somehow degrade other cells sooner?if there is a formula for write/erase damage ratio what is it?I use stm32g071 but I expect this to be common use case. 

Hi gm, I am creating a project in STM32CubeIDE with touchGFX, right now the project builds, but when i pass it to the board the screen shows white, and when debugging I noticed that when it gets to the line tick() in                              HAL.hpp->backPorchExited which is called from TouchGFXHAL.cpp the code stops,  And I really don't understand this, the function itself is empty in HAL.hpp and it's called from inside the HAL class so i don't get how is this making my code stop. I don't really know what kind of screenshots I can provide here, let me know if you want me to pass the project files or something.

Hi everyone, Recently started working on STM32C011J4M3. I'm trying to set PF2-NRST pin as a GPIO and I want Pin 4  to multiplexed  to PA0 USART TX pin. At first i tried  multiplexed the Pin 4 to PA0  using the following API                        " LL_SYSCFG_ConfigPinMux(LL_PINMUX_SO8_PIN4_PA0);"  but this didn't work  and to mention that this API function worked  on Pin 1 and Pin 5. I came across this post  to  set PF2-NRST pin as a GPIO  and change the Pin 4 to PA0 thinking that  multiplex is only done with GPIO Ports. I tried above code to set the NOT_RESET_INPUT_ONLY bit and clear the NOT_GPIO_MODE_ONLY bit of the FLASH option bytes  this works in Registers but to my surprise  the Pin 4 still works as PF2-NRST pin  and not as GPIO. Debugging works as always and when i remove the Pin4 connection  from debugger  I receive  console

Hello,I'm working on a UI with touchGFX, and I was wondering which is the better practice in order to maximize performances and memory managment: is it better to create a new screen for each page of the UI, or to keep screens at minimum and to play with invisible/visible widgets?I'm creating a menu to setup a weekly schedule. I use a single screen for the entire setup flow, and for each step of the setup I turn visible only the widgets I need. When the user completes that step and pass to the next one, all those widgets become invisible and new ones become visible.I'm proceeding like this because the choices made in the previous steps influence the aspect of the following steps, and being in the same screen its easier to access those info. But since the widget counter is going through the roof, I'm wondering is this approach will give me performance issue in the future!Do you have any advice/consideration?

I think there is a bug with code generation when USB_OTG_HS_Dx is selected for PA11 and PA12 pins and USB_OTG_HS peripheral is not active:then there is this code generated in MX_GPIO_Init() function: /*Configure GPIO pins : PA11 PA12 */ GPIO_InitStruct.Pin = GPIO_PIN_11|GPIO_PIN_12; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);  .Mode is set to alternate function but there is missing setting of GPIO_InitTypeDef.Alternate field. In this case, USB is not Alternate function but Additonal function, which means that no configuration is needed here and the USB peripheral manages it itself when it is configured. Indeed, when USB_OTG_HS peripheral is initialized from the GUI, this code disappears. I think this is a bug because in our case, code like this was generated: /*Configure GPIO pins : PB14 PB15 */ GPIO_InitStruct.Pin = GPIO_PIN_14|GPIO_PIN

I've connected an STM32F103RBT6 Nucleo-64 to my computer and it worked fine for sometime, and then suddenly it lost connection. What is weird is that with the same cable, another identical board can connect without any issues. Does anyone have solution to this problem? (and it won't connect on other computers either).

Hi,I am looking for bidirectional mailbox example for the st25dv chip. I have an ANT7 nfc connected to a nucleo with the NFC7 mailbox example and the NFC Tag iOS App. I can read the mailbox stuff send from the Tag to the iOS App. But the other way around is not clear. Neither the GPO pin is toggled accordingly. Do you have an example / demo code available for this. kind regards, C.W.

Stm32CubeIDE 1.14.0, STM32CubeMX 6.10.0, STM32CubeFW_U5 V1.4.0, X-CUBE-FREERTOS.1.1.0   This started with the Stm32CubeIDE 1.14.0 release and worked fine in 1.13.x.  It happens for new projects and migrated projects.  I'm using it with an STM32U5. Go into the Task and Queues tab in FreeRTOS and add a Queue. Change the Item Size to uint32_t.  This needs to be different.  Click OK.  The item size is uint16_t (the default).  Edit it and it's uint16_t.  You can't change it in the UI.   I need to manually create a Queue to be able to set the item size.
