Hello, I've been trying to make this project since the PART 1   STM32 Graphics: Getting Started with the Gauge Widget, Part 2 , following every step, but my program crashes in MX_TouchGFX_Init(). I was debugging and the error message shown is "No source available for "touchgfx::PartialFrameBufferManager::tryTransmitBlock() at 0x800660c". I have the G071RB + GFX01M2. I hope someone can help with this problem. Thank you !

Hello, I am using STM32H503 for precise time measurement hence I need to tune the PLL that output frequency compensates the voltage or temperature drift of the HSE crystal.My setup is:- Clock configured as HSE=16, M=, N=337, Nfrac=4096, P=2 which should give HCLK=180MHz- External, high class reference GPS clock (1PPS) connected to TIM1 as ETR.- TIM2 CH1 in IC/TRC mode with DMA readout to measure the HCLK.The procedure is as follows:- DMA reads TIM2_CH1 CC values into buffer in circular manner (size of buffer is 30 dwords)- on every HT/TC interrupt I am averaging measurements, taking into account only those within 2% of target frequency- I am calculating the HCLK error, and correction to be applied to PLL1 Nfrac register.Update of the Nfrac is done according to to RM492, i.e. to enforce 0->1 transition of the RCC_PLL1CFGR_PLL1FRACEN and later wait for RCC_CR_PLL1RDY to becom

1) There is no availability of the X-NUCLEO-IHM09M1 at Mouser or Digikey. Both vendors do, however, have stock of the X-NUCLEO-IHM09M2. Has the M1 been discontinued? Please let me know if there is any difference between the M1 and the M2.2) If it turns out that the M2 replaces the M1, does SB26 still need to be removed? It’s going to be very difficult to remove SB26 without damaging the board due to its tiny size and awkward location.3) I also need the specs and part number on the 34 pin ribbon cable that interfaces the B-G473E-ZEST1S controller board to the STEVAL-IPM30B evaluation board.

Hello,I am trying program the flash memory on an STM32f401RE.After successfully programming sector 7 I cannot flash a new application to my board, instead I am met with :Error: ST-LINK error (DEV_TARGET_NOT_HALTED) I can flash new code after a mass erase with cube programmer but this shouldn't be necessary.

Hello,I’m experiencing issues while programming the RVT101HVSFWCA0 Riverdi display. Specifically, I encounter errors when uploading my project using TouchGFX and STM32CubeIDE.I would greatly appreciate your assistance in resolving this matter. I’ve attached a screenshot showing the errors and my current connection setup.

Hello, I am trying to implement a zigbee network using stm32wb55 custom board. I use STM32Cube_FW_WB_V1.21.0 zigbee examples. Everything works perfectly, butI want to change the client/router 64 bit IEEE address, but I can't find where it is set or hard coded in the code.I have to change it because end devices must have unique IEEE addresses.

I have a custom board with an STM32G473 running at 170MHz. I have the QSPI peripheral running correctly in indirect mode when the pre-scaler has a value of 5 (so ~23MHz) but when I decrease the pre-scaler any further all HAL_QSPI_Receive calls end up failing silently. I've tracked it down to the QSPI_WaitFlagStateUntilTimeout returning an error due to what seems like a timeout. Here's a snippet of my initialization code:  flashSPI.Instance = QUADSPI; flashSPI.Init.ClockPrescaler = 2; flashSPI.Init.FifoThreshold = 1; flashSPI.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_NONE; flashSPI.Init.FlashSize = 27; flashSPI.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_1_CYCLE; flashSPI.Init.ClockMode = QSPI_CLOCK_MODE_0; flashSPI.Init.FlashID = QSPI_FLASH_ID_1; flashSPI.Init.DualFlash = QSPI_DUALFLASH_DISABLE; __HAL_RCC_QSPI_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); // Initia

"I followed along with this video, but I have some questions. How can I correctly retrieve the ADC array values via UART communication? And why is the UART value coming out as garbage in this video?"https://www.youtube.com/watch?v=_hX6pN2jgYMhttps://rristm.github.io/tomas_materials_v2/RRISTM/stm32u5_workshop/master/2_gpdma_handson_list_mode_mx.md/17 I think it's a clock issue. How can I fix this?

I am working on a BLDC motor control project using ST MCSDK Workbench 5.4.7. The motor has 15 pole pairs.When I configure the system to use a quadrature encoder, I can rotate the motor and successfully control its speed in both directions using the Workbench. However, when I switch to Hall effect sensors (HALL _H1, HALL_ H2, HALL_ H3), I can still rotate the motor in both clockwise and counterclockwise directions, but speed control does not work. The motor spins at a constant speed, and changing the speed setpoint in the Workbench has no effect. Kindly help me in this. 1.What would be causing the speed control to fail when using hall sensor?2.Are there specific settings or configurations in MCSDK workbench for Hall sensors that might be affecting speed regulation? 

How to Generate a 3-Phase SPWM Signal Using Only TIM1 on STM32G031K8 or STM32G071RBT6?   I’m trying to generate a 120-degree phase-shifted 3-phase SPWM signal using only TIM1 on either an STM32G031K8 or STM32G071RBT6. My goal is to drive an FSBB30CH60C IPM module with complementary SPWM signals to control a 3-phase asynchronous motor, similar to a VFD (Variable Frequency Drive).   Has anyone done this before? Any tips, example code, or best practices would be greatly appreciated!    

Hi,I want to use CLion for development, which requires CMake, and I've been struggling with integrating the X-CUBE-MATTER package in it.Globbing all files withfile(GLOB_RECURSE src_files "Middlewares/*.c" "Middlewares/*.cpp" "Drivers/*.c" "Drivers/*.cpp")produces a binary significantly larger than FLASH and still fails to compile because it includes various examples and templates.Another option I thought of is manually adding all the necessary files, however that seems like a herculean task.Is there an easier way to go on about this (perhaps ST is already working on it)? Thank you for your reply.

Trying to update from an old version of TouchGFX to the current version. I am having problems with the colors from fillRect(). I see in the 4.18.0 bug notes that "LCD16bpp::fillRect() and LCD16bpp::drawGlyph() now passes 24bit color instead of native 16bit color to DMA. I read that the fix was to regenerate these files but I do not have access to the original configuration for creating these as this project is many years old. Is there any way to make the necessary changes to the DMA manually?The original project is built on TouchGFX 4.5.0.

Hello everyone,I am currently working on a project with the **STM32 B-L475IOT1A2C** and I am looking to implement a BLE *observer* mode to scan for nearby BLE devices. My goal is to retrieve the MAC addresses of the detected devices and analyze the content of the BLE frames being sent.I have already set up my development environment using **STM32CubeMX** and **STM32CubeIDE**, but I am facing a few challenges:- How do I properly configure the **STM32 B-L475IOT1A2C** to work in BLE *observer* mode?- What libraries or functions should I use to scan for BLE devices and retrieve their MAC addresses?- How can I analyze and display the contents of the BLE frames received from the devices?If anyone has worked on a similar project or can guide me with code examples or additional resources, it would be greatly appreciated!Thank you in advance for your help!

Hello, I’m trying to use the PyOCD library to program an STM32H747 and an STM32U5A9 using .hex or .bin files generated by STM32CubeIDE. So far, I haven’t had much success, and I’d like to know if anyone has experience with this or can offer guidance on how to proceed. I’m also open to alternative ways of programming these devices besides using TouchGFX or STM32CubeIDE.

I am a student in embedded systems. I have a final project with the stm32h747i-disco card. I want to configure the touch screen to make a graphic interface.

Hi all!First time poster.I'm working on a prototype that utilizes a Nucleo-G474RE to move some motors and read some sensors. The design is working great and my code is running as it should. However, recently I've been having some issues with the virtual COM-port on my Nucleo board. Whenever I program the device, it works perfectly.When I unplug and replug the USB however, my serial connection doesn't respond in any way. This is true even when I plug in a completely fresh Nucleo directly to my PC, powered by 5V_STLK, no peripherals. The status LEDs on the device do function as expected, but no messages are received or transmitted.Plugging in and then resetting the micro or removing and replacing JP6 fixes the issue, making the serial work again.There has been a firmware update to the ST-Link 3 that's built in, and we made some minor changes to the code, but even rolling back to a known working version of our firmware does not help. I want to share o

Hi All,I've been trying to bring up a custom external loader for well over a week and I'm just not getting anywhere.My processor is an STM32L496VGT6 and its connected via quadSPI to an MT25QL128A 16MB external flash memory. I'm running the clock at 80MHz, and my QUADSPI is setup like this (both in my custom loader, and in the application code I'm developing):

Hellow In DS10639 P105 [6.3.10 internal clock source characteristics], regarding the measurement conditions of TA (ambient temperature) described in Table 41:Is the measurement method of TA (ambient temperature) based on the temperature of a thermostatic chamber, or is it the temperature measured at a fixed measurement position? If it is the temperature measured at a fixed measurement position, please provide the distance from the CPU to the measurement position.What is the operating time at the ambient temperature being checked? (e.g., measuring drift after operating at 80°C for 2 hours)Could you provide data equivalent to Figure 1 in AN5076 P6 [2.2 Drift of internal oscillator before and after reflow] for the CPU "STM32F446ZCJ" being used?In AN5076 P8 [3.1 Thermal effects], the fifth line states "(The frequency may increase, but this is rare)", but in Figure 1 of AN5076 P6 [2.2 Drift of internal

I am using a Nuclro-303RE to develop a USB Virtual Com port, and I am running into an issue that I cannot seem to resolve.  Just to verify things, I did put some really simple code in the flash the green indicator on the Nucleo board.I have it connected to a custom board that runs the USB lines out to a USB connector.It is powered externally with 5V to VIN. Jumper set for E5V. The power indicator on the Nucleo is on, and the 3.3V is running.I am able to run it with the debugger tool, however, it will not run with just the USB and the 5V in.When I plug in to the USB on the ST-Link board, it starts to run, i.e. the green LED will blink, and the USB will enumerate for the USB virtual com port.I did add an 8MHz oscillator @ X3 and associated parts.I do have a pull up on the USB line.

I want to add a USB thumb drive (mass storage) to a NUCLEO-144 F767ZI board. I see the STM32CubeIDE can be used to point GPIO lines PA8~PA12, PG6, PG7 to connector CN13 (USB Micro-AB) or to the Morpho connectors to realize a USB OTG (On the Go) interface suitable for thumb drives.Three questions - 1.  Is it possible to use the STM32CubeIDE to configure the NUCLEO for USB OTG **and** also have Micropython running for the main application code? This may be thought of as a 'hybrid software' solution leveraging parts of STM32CubeIDE (for USB OTG setup) and Micropython.  Preferably, I'd like to implement the USB thumb drive in Micropython exclusively, but I've not found a solution to do that.2.  Any suggestions for a purely Micropython implementation of STM32 USB OTG interface to support a USB thumb drive?3.  Any suggestions (is it even possible?) for a hybrid software solution that uses parts of STM32CubeIDE to co
