Solved

I have been working on an application with multiple DMA channels and timers.  For some reason, STM32CubeMX doesn't have the proper drop-down options for TIM15_CH2 in the DMA channel configuration. All the other timers and channels appear to configure properly:Here is the generated code.  My fix/workaround is shown in RED, while the code generated by STM32CubeMX is in GREEN:Luckily, we do have the work-around, but the problem has become relatively annoying.  Thank you in advance.  

Hello, I have seen in the post That many users had a problem with the LDO power supply for STM32H757ZII wanted to ask, can you confirm that I have a correct implementation of the power supply for LDO? 

It's still available in the PCC section, for the User section table for the modes: Post created from a comment on this post: Meaning of IP in STM32CubeMX - STMicroelectronics Community

Hi,I can't debug my STM32WB09. I can execute a few lines (it's not a specific number, it may be random), and then CubeIDE throws the following error and disconnects from the board. The board is based on the Nucleo-WB09KE (NUWB09KE$CR1). Below, I’m attaching an image of the adapted board and another image of the error. I’m also including the project zip file. The project itself isn’t particularly complex, other than the addition of a .c file to handle the data generated for BLE transmission.Please, if you can help or guide me in debugging the project, I’d really appreciate it.      

Hi,We designed a custom board that includes the STM32WB09KE microcontroller. We're working with a BLE middleware, and when I try to run the code, it doesn't go past the line LL_RCC_RC64MPLL_IsReady() during the clock configuration in SystemClock_Config().As far as I know, the code should work, since it runs correctly on the Nucleo-WB09KE (NUWB09KE$CR1). Below is a photo:If I don't enable the PLL64M, the code runs fine and I can, for example, make an LED blink. However, I lose the RADIO functionality, which is essential for my project.I'm also including the main.c code atached, along with a physical photo of how the microcontroller is currently "wired up".   

Hi,I'm using a 2MB flash version of STM32U585x MCU and noticed that when the bank swap bit is set in OB, the wrong page will be erased if I edit flash using the "Memory & file editing". It seems like the page to be erased doesn't take the bank swap bit into consideration.To elaborate a bit: If bank swap is disabled and I edit some memory at e.g. 0x08006000, it will correctly erase page 3 before writing the new data. But if I have bank swap bit set, and edit the memory at 0x08006000 it will still erase page 3 before writing even though it should be erasing page 3+128 since it's this page that is now available at 0x08006000.This had me very confused before I understood what was happening.

Hi folks.I am trying to optimize (by time) the following piece of code. for (uint32_t i = 6 + adc_data_index; i < 35 + adc_data_index; i++) { raw[0] += (adc_data[i]); raw[1] += (adc_data[i + 35]); raw[2] += (adc_data[i + 70]); raw[3] += (adc_data[i + 115]); }For now it takes 3.5 micro-second at 250 MHz clockI want to make it less by at least factor of 2.Do you have any ideas?What I tried:1. Change the optimization to be -Ofast2. Using pointer3. Also, thought about FMAC and DFSDMHow can I achieve that?ThanksYonatan

Hi,I am working with a custom board with the STM32L431CCU6 mcu. The bord consist of the mcu and 2 i2c units and one SPI.The board also has pin headers for BOOT0, SWDIO and SWCLK.Sory for paint... I am using the CubeIDE and a ST-LINK V2for programming the board and have successfully programed Blink on it. This was not problem free however since my coputer sometimes did not recognised the ST-LINK and sometimes failed to upload. Unfortuanatli I do not remember those errors in details.After succesfully uploading a program for i2c communication I could not program the board any more. The error i receive from the IDE is:STMicroelectronics ST-LINK GDB server. Version 7.9.0 Copyright (c) 2024, STMicroelectronics. All rights reserved.

hi im using stm32g474vet6 mcu , im using spi in dma mode of both tx and rx and made dma in circular mode.what happens means when i start a first tx or rx itself spi clk is coming continuously. what to do , it is due to circular mode.if (send_spi_cmd == 1){send_spi_cmd = 0;HAL_SPI_TransmitReceive_DMA(&hspi3, ADS_TX_NULL, ads_rx_buff, 1);} if u see this code im just enabling in debug mode one time onlym the spi clk starts generating continuously. what to do for this this spi clk should generate during bus activity only right. can someone suggest it is due to circular mode or what 

Hello everyone, I am currently working with the VL53L8CX sensor to explore solutions for a specific use case. In particular, I am trying to detect glass material using the CNH (Compacted Normalized Histogram) data—more about this can be found under the topic: Artificial Intelligence Enabler .From my research, I understand that the sensor generates a total of 121 histogram bins. However, due to constraints such as memory limitations, only 18 or 24 bins can be accessed, depending on the configuration used.I started by configuring the sensor to retrieve the first 24 bins and set the subsample value to "1", so that each bin corresponds to a single zone. Then, I attempted to determine the first significant return using an interpolation algorithm I found online. According to the documentation, I multiplied the resulting value by 3.75 to obtain the actual distance.def interpolate_bin(signal_values, ambient_light_level): for i in range(len(signal_values) - 1): if signal_values[i] &

  Hello, So I'm tackling a DMX512 project using an STM32G0C1CE with Zephyr OS v4.1.0 and I'm running into a bit of a snag with detecting the BREAK and Mark After Break (MAB) signals to start receiving the DMX slot data via USART. I've already tried a couple of things: Using the framing error detection, but that didn't seem to work out. Since I only have the USART3_RX pin available at PB11, I tried configuring it as a GPIO input to catch the BREAK and MAB using a GPIO interrupt. After detecting them, I switched it back to USART_RX mode. This allowed me to see the BREAK and MAB, but I couldn't reliably grab the subsequent DMX slot data within the USART interrupt. Code: #include <stdio.h> #include <string.h> #include <zephyr/kernel.h> #include <zephyr/device.h> #include <zephyr/devicetree.h> #include <zephyr/sys/util.h> #include <zephyr/sys/printk.h> #include <zephyr/shell/shell.h> #include <zephyr/logging/log.h> #include <ze

板：STM32G431 NUCLEO-64我的目标是在 ADC1 和 ADC2 上实现 4 MSPS 的采样率。通过使用交错采样，我的目标是获得 8 MSPS 的有效采样率。虽然我知道这可能与数据表中针对多通道 ADC作的声明限制不严格一致，但我相信这种差异与我遇到的问题没有直接关系。根据数据表中的图1、ADC 时钟应低于 52 MHz。图 1在我的设置中，我在交错模式下使用 TIM + DMA + ADC，配置如下：定时器触发频率：4 MHzADC 分辨率：12 位ADC 时钟：60 MHz采样时间：2.5 次循环我的输入信号是由板载 DAC 生成的连续正弦波，频率为 50 kHz。在查看与 timing calculations相关的 datasheet 部分后，总转换时间似乎应该在7.5 cycles 左右。但是，STM32CubeMX 只允许采样时间设置介于 1 和 12 之间的整数值，因此我选择了 7 个周期。以下是我观察到的：当我将“Delay between 2 sampling phases”设置为 7 个周期时，采样间隔看起来不规则，并且与预期的交错模式不匹配（参见图 2）。当我将“Delay between 2 sampling phases”设置为 12 个周期时，得到的采样间隔看起来是均匀分布的（参见图 3）。  图 2 Figure 3What I want to understand is:What is the correct value to set for “Delay between 2 sampling phases” to achieve ideal interleaved sampling with evenly spaced samples?  

Hello,I'm using in my projects with ports PA10,PA11 (for Logs - uart), and PB14 and PB15 as normal GPIO.They didn't works.After long troubleshooting.... I found out that is because these ports are supply separately by the VDDUSB pin which was disconnected.I couldn't find the reason in the datasheet, I'll be happy to understand the construction and the reason.  

Hi,I'm working with the LIS2DW12 accelerometer in a low-power IoT application. The sensor is configured to wake the MCU via an interrupt on INT1, connected through a monostable multivibrator (Schmit trigger IC). The setup is designed so that a rising edge on INT1 triggers a reset of the MCU.Here’s the issue:When the MCU wakes from a previous interrupt (caused by actual motion), it starts reinitializing the LIS2DW12 — performing a soft reset and reconfiguring the registers into polling (standard) mode. Then, after some time in polling mode, if no motion is detected, the program switches the LIS2DW12 back into interrupt mode.At this point, the INT1 pin briefly goes high, creating a glitch pulse even though the system is stationary. This unexpected edge triggers the monostable multivibrator, which in turn resets the MCU — essentially creating a loop. This behavior is not acceptable for my use case.What I’ve tried:Delaying the CTRL4 write until after all other registers are configured (CTR

EDIT: it's not the STM32, see latest postHeyho,I have some custom miniature PCBs here, the unholy combination of a super-high-impedance-low-noise amplifier (going to a low noise audio input with 24bit ADC, spectra below from that one) and a STM32L031 on another PCB.Both circuits share the same ground and power supply.Actually, I didn't expect the analog part to be that good (shielding issues), so I was greatly annoyed when all got worse when adding the PCB with the MCU.I already got the noise down by not using the CPU sleep mode: the timer interrupt frequency of 10 kHz was clearly visible in the spectrum, seemingly due to powering the CPU up and down.Now the noise doesn't change, no matter which peripherals I turn on or off - and even in hardware reset (NRST grounded) there are the same noise spikes at around 4 kHz (and harmonics) on the analog signal.Noise is only about -80 dBV = 100 µV, but I'd like to find out where that comes from - even with the MCU in reset.Here are some scr

We are currently developing a demo product using the STM32MP257F-DK board.We have flashed the firmware using the file .images\stm32mp25-disco\flashlayout_st-image-core\optee\FlashLayout_emmc_stm32mp257f-dk-optee.tsvHowever, we found that the USB DRD port (CN15) is not being recognized.Upon checking the device tree source in the kernel, we observed that the USB3DR functionality appears to be controlled via , suggesting that an MCU may be required for this functionality.i2c_rpmsgWe would like to confirm the following:Is the USB3 Dual Role (USB3DR) OTG feature dependent on the Cortex-M33 MCU for proper operation?Is it possible to enable and test the USB3DR OTG function without involving the MCU, especially if our goal is to minimize power consumption?Can the CC (Control Channel) pins be handled purely on the A7 side, or is MCU intervention mandatory for proper role detection and control?What is the correct way to enable and test USB OTG functionality on the STM32MP257F-DK board

Hello all, I recently purchased a Nucleo H503 board to experiment with. The board itself works just fine, but I've been having trouble getting it to work with the VSCode STM32/cortex-debug plugin. I just want to emphasize that using CubeProgrammer, I can connect to the board just fine and I was able to flash my test firmware that way. I also tried an ST-LINK V3SET that I borrowed from work, which also functioned just fine using CubeProgrammer. When I try to debug the board using VSCode, I just get an error about not being able to connect to the target. Below is the launch.json I created for my project.   { "version": "0.2.0", "configurations": [ { "name": "Cortex Debug", "cwd": "${workspaceFolder}", "executable": "./build/h503dk.elf", "request": "launch", "type": "cortex-debug", "runToEntryPoint": "main", "servertype": "stlink", "gdbPath": "C:/arm-toolchain/bin/arm-none-eabi-gdb.exe", "serverpath": "C:/ST/STM32CubeCLT_1.16.0/STLink-gdb-server/bin/ST-LINK_gdbserver.exe"

I have Stm32wb55Cgu6 board from from WeAct, With default FUS (V1.2) and BLE stack everything was okay. But when i upgraded the FUS 2.0 and newest BLE stack Full 1.22.1 . the Upgrade was successful, But I didn't got any Bluetooth connection for same code.So I decided to delete the stack and install 1.19.1 old stack with FUS 2.0, but i cant, it shows "Warning: FUS-STATE_IMAGE_NOT_FOUND". I also get the same image when i try to change The FUS version itselt to 1.2.Now neither I can Upload any version of FUS nor any BLE stack. I also used USB DFU Mode none can erase and download FUS or BLE stack at sector 0. The application just hangs up.Im using  STLink Programer V3 Set.I also tried mass erase and try to download the FUS and stack again and it wont work.I have checked after mass erase there is no value at FUS start address by reading the flash, yet shows FUS version.Option ByteI understand that portion of the flash is secured and meant to be used by co-processorWhat could be source o

Hello, my program runs to the HardFault _ Handler function, I usually use interrupt check whether there is a function variable overflow, but this time the jump function is irregular, I do not know how to judge, please help me, I will provide the relevant information you needIt finally jumped into the DMA function, but I had no idea why it would trigger HardFault _ Handler, let alone call the UART _ WaitOnFlagUntilTimeout functionSometimes, my program will jump directly from UART _ WaitOnFlagUntilTimeout function to HardFault _ Handler, in the following line, and I know through debugging that the huart 's Instance is NULL, which makes me not understand. if (Timeout != HAL_MAX_DELAY){ if (((HAL_GetTick() - Tickstart) > Timeout) || (Timeout == 0U))//this line jump to HardFault_Handler { return HAL_TIMEOUT; }I am using STM32G431RBT6, using three UART and its DMA.Thanks.

Hi I've been trying to display an image on the GUI using an image (hex array) stored in the QSPI flash (memory mapped). I've taken a look at some of the documentation such as Loading Images at Runtime & Dynamic Bitmaps. void LandingView::loadImageFromQSPI(Image& imageWidget) { BitmapId bmpId = Bitmap::dynamicBitmapCreateExternal( 185, 43, (const void*)0x90FC0000, Bitmap::RGB565 ); if (bmpId != BITMAP_INVALID) { imageWidget.setBitmap(Bitmap(bmpId)); imageWidget.invalidate(); // To trigger redraw } } FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap) : FrontendApplicationBase(m, heap) { Bitmap::setCache(touchgfxCache, sizeof(touchgfxCache)); } When debugging, I keep getting BITMAP_INVALID? I've made sure I'm in memory mapped mode. 

I'm having some difficulty getting debugging working in VSCode for the N6 series.  Does anyone have a sample one that actually works?  I'm obviously using the `stlink` server backend for `cortex-debug`, and I have tried using CubeIDE to get the exact gdb-server arguments used when it launches a debug session.  However even when I do that, I still end up with a corrupted stack pointer or missing sources?   The symptom is that the debug session says something to the effect of "??@<hex>  Unknown Source".  It also seems to have problems halting the core at startup.Here's something representative of the config I'm using right now:  { "version": "0.2.0", "configurations": [ { "cwd": "${workspaceFolder}", "executable": "${workspaceFolder}/FSBL/build/<my_project_name>.elf", "name": "Debug with ST-Link", "request": "launch", "type": "cortex-debug", "runToEntryPoint": "main", "showDevDebugOutput": "none", "servertype": "stlink",

Hello everyone, I’m currently working on developing a USB audio device with multichannel audio functionality using the STM32H7S78-DK in combination with the X-CUBE-AUDIO-KIT. My goal is to use LiveTune to build audio flows and to implement USB Audio Class 2.0, potentially with extended multichannel support. Unfortunately, I haven't been able to get the provided example projects to work correctly on my board. I’ve run into several issues using both STM32CubeIDE and STM32CubeProgrammer, and I’m hoping someone with experience using this specific board or the X-CUBE-AUDIO-KIT can help me move forward.   What I’ve tried so far: Flashed the bootloader (X-CUBE-AUDIO-KIT-STM32H7S78-DK-BL.hex) to address 0x08000000 (internal flash) using CubeProgrammer Flashed the LiveTune firmware (X-CUBE-AUDIO-KIT-STM32H7S78-DK-Designer.bin) or other .bin files to 0x90000000 (QSPI flash) Verified that BOOT0 is set to 0   Current status: The board is detected correctly via ST-LINK The boo

Hi eveyone!I am using TouchGFX Designer 4.25.0In the real world, you can only move a linear slider control by touching/moving the slider knob itself. One of the issues with using the TouchGFX Slider Widget is that it will instantly move from one position to another by touching/clicking anywhere on the slider scale. The graphical indicator (knob) is only there to indicate where the new setting sits on its scale of 0% to 100%.I have 16 sliders, eight of which are visible at any one time. With my application, it would be a disaster if a user "accidentally" touched a slider (scale) and moved a setting from very low to very high in an instant. I have seen one post (a medical app !!) where the designer has the same problem.++++++So far, I have half a solution and would like to ask for help on how to solve my current dilema. Thanks in advance.void ChannelFader::UpdateStatus() // Slider adjustment confirmed { /* other code here */ sliderChSlider.setTouchable(false); }Here, I h
