Hello,I use tft screen with touch panel. All buttons react on the touch correct beside radioButton and toggleButton. I used "small version" of toggleButton and medium of radioButton. Screen 240x320. When both of that buttons are on the centrer of the screen it correct reacts to touch. When that buttons are on the left or on the right of screen they not react on the touch. I am sure that touch screen library works correct. Reading of touching coordinates works very well and the measurement is accurate. It looks more like the error lies more with TouchGFX.

Hi, I was wondering if there is a reference design available for STM32WB55 based product. I am designing a system based on this MCU using the datasheet and application notes such as AN5165, but it always helps to see implementation of existing product. One I found was NUCLEO-WB55RG, but I cannot find schematics, are they public? If there are any other reference designs that are close enough, could someome point me to them please?Best regards,STMDesigner  

Hello to everyone.I'm using the  board NUCLEO-C071RB, and now i want project my board.I have a question about the pin PB3:From the schematic it seems PB3 = SWO but if i try to configure the pin with STM32CubeIde i don't find that option.

I intend to design a microcontroller circuit with a BTA40-600B RD91 to control the power delivered to a heating resistor (220Vrms, 12Ω, 4KW). I thought about using the MOC3023 to mediate the activation of the BTA40, but I don't know if it is the most suitable optocoupler. Another question is about the snubber circuit. The load is purely resistive, so is a snubber circuit really necessary? Thanks for the help.

Hi,I'm aware of the manual from https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image but it does not solve my problem as it seems to be completely faulty:different to the description, not USB has to be choosen as connection but UARTwhen downloading, there is never a completion-message but it always ends up with an timeout (no matter what image I try)at the end, it comes up with an error message "Partition 0xBB not found in TSV file"the resulting SD-card obviously has not changed at all after this cycleSo where can I get an image for the Sd-card that can be copied with a simple imager or the dd-command from Linux instead of following this non-working, complicated procedure? 

We have implemented the following circuit. This matches the application circuit given in datasheet of LDO29300P2MTR.But it does not yield expected output. We need help!!

Hello,I am trying to run a BLDC motor using the MC control SDK. The BLDC motor is the following: BLDC 40P30F16P2.063D by MinebeaMitsumi. First, I entered its parameters in MC Workbench + made the profiling for its mechanical parameters, however this step didn't went as expected since I cannot run the motor in full speed, the MC Pilot gives me speed feedback error.Anyway, I was able also to get the electrical angle offset using the oscilloscope (you can find the picture attached) (which is 120 degree). In addition, I tried to run the motor in Voltage and Current open loop as per the manual. I was able to run it without major problem.However, when I want to run it in closed loop using the hall sensors, the motor won't turn smoothly. It starts to do a back and forth movement. I tried to tune the PI of the speed control however nothing is changing. + I monitored the hall effect sensor through oscilloscope when I command the motor to run, there are is no noise affecting the hall effect

Hello everyone,I’m a computer engineering student looking to build a custom Time-of-Flight (ToF) camera around the VD55H1 sensor die. I have multiple projects I would love to do that require a TOF sensor/camera, but as I have searched around they are often quite expensive. As a student on a tight budget, I decided to build my own TOF camera instead —not only to cut costs but also to gain a lot of experience and do a fun project.However, I’m finding the available documentation and reference designs a bit sparse, and I have several questions on how to get started. I have a lot of experience in low-level programming, but I'm relatively new to hardware design and PCB development. I’ve settled on the VD55H1 (0.54 Mpix iToF sensor die), as I found most other TOF sensor dies has really small resolution, and most of my project requires a detailed point cloud. Now for all of my questions:The VD55H1 data brief references an illumination system (VCSEL + Laser driver). Is the “

Hello. I would like to write my own bootloader, but jump function does not work. could you send a complete example for stm32U575. 

Designing custom board based on STM32F746G-DISCO.  I am using the TQFP chip, so a few less IO.   The DISCO board uses a 4 wide data, but I do not have enough pins so I will only have 1 bit wide data.  I only want to use SD card to be able to upload new firmware via bootloader. Can the bootloader work with 1 bit data?

@Tesla DeLorean  Hi! I wonder if someone can help me! I am trying to initialize a LCD screen and I have some questions. I am using a STM32F469IIT6, and it does not have enough memory in itself to hold a buffer for my screen 800x480. I did not set up a DMA to use an external memory o handle the buffer, however I have the following questions: I - What would happen if I assign a smaller buffer for the LTDC? will it still paint partial part of the screen, or it will not work at all? II - Once I set the background colors in the .ioc, give the buffer address in the configuration and do not use the function: HAL_LTDC_SetAddress(&hltdc, buffer, 0), will the buffer be filled with the colors set in the background?   I've set up a logic analyzer to try to answer these questions, however, unless I am understanding it wrongly, my buffer is so small compared to the size that I need, that it is being very difficult to identify the colors I am inserting, if it is the case that I am

Hello, As a newbie to STM32 , Could some experts please answer these questions for meIs there any basic documentation that provides an overview of what software i will be needing installed on the PC? This is what is my understanding so far, there is STM32CubeIDE and STM32CubeMX, STM32CubeIDE is an eclipse based IDE and the STM32CubeMX is a standalone graphical user interface to configure the different MCU peripherals. But I read somewhere that the CubeMX is now integrated into STM32CubeIDE (so why do we need the standalone STM32CubeMX anymore)? Regarding the ST-Link debugger , do we need to get a separate standalone debugger/Flasher ? I think the discovery boards come with the debugger circuitry ..so all i need is a USB cable? Please confirm.Is it absolutely necessary to use CMSIS? , I notice that when we generate code always there is a CMSIS folder being created. Cant a project be made without the bloated HAL libraries, Is there an option for this?, If so any documentat

Hello, I am using the NucleoWL55 for transmitting and receiving the data. I am able to transmit and receive the data in HEX, and when I observed in SDR# using RTL SDR I observed the burst data. I want to know if the NucleoWL55 can transmit the CW data or not?,,  Please, help

Hi everyone,I'm currently working on a BLDC motor control project using the STM32F103RB (Nucleo-F103RB) board. I have two questions regarding handling 5V logic signals with this MCU:I need to read 5V logic-level signals from a BLDC motor's Hall sensors. As far as I understand, most GPIOs on the STM32F103RB are designed for 3.3V logic. However, I read that some GPIOs are 5V-tolerant.→ How can I configure GPIO pins in STM32CubeIDE to safely accept 5V logic inputs from the Hall sensors? Is there any specific setting in the GPIO configuration in CubeMX/IDE, or are the 5V-tolerant pins automatically handled by the hardware?I'm also using SPI to communicate with a motor driver IC. In this setup:STM32 sends 3.3V logic signals via MOSI.The motor driver IC responds with 5V logic levels on MISO.→ Is it safe to connect the 5V MISO signal directly to the STM32F103RB? Can STM32 SPI peripherals accept 5V logic levels on the MISO line without damage? If yes, do I need to configure anything specific f

Need to IAP save two 16(10) bit ADC values to EEROM. Done parm saves before in STM8S105, but want to see it in ICP mode.In NXP MC9S08, I can turn off download, which cleared Its EEROM. That let me run the ADC "learn" of the values, save them to EEROM, then power cycle and see them retained.I'm thinking running debug without download will be the same, but I can't find it.SO, I want to test "stuff" two values to EEROM, power down / up, invoke Debug (ICP) and see them preserved.Trusting IAP to get/save values without verifying doesn't sit well. Like Reagan: Engineers don't Trust - they Verify!Deeply appreciate my "betters", everybody old enough has been on BOTH sides of this!!  Thanks, Kevin

I am working on X-CUBE-AZURE in B-U585I-IOT02A board. My IDE version is 1.18 and i am using Fedora 41. When i enable FDCAN peripheral in CubeMX it places the stm32u5xx_hal_fdcan.c and .h file into the X-CUBE-AZURE/Drivers/STM32U5xx_HAL_Driver/Src. Even though it places the correct .c and .h files the build fails when i enable FDCAN from CubeMX.

Hello everyoneIt's my first time messing around with STM32 microcontrollersA few days back I got a black pill (STM32F401CCU6 - https://robu.in/product/stm32f401ccu6-minimum-system-board-microcomputer-stm32-arm-core-board/) and an ST-Link V2. The black pill came with 3 buttons, namely (KEY, NRST, BOOT0) and a USB-C Port. Since the ST-Link was arriving later, I connected the black pill to my PC through USB-C. The PWR LED on the black pill turned on. I pressed down the boot0 button, clicked the nrst button and then released the boot0 button to enter the dfu mode (according to the guides I saw online) I fired up the Arduino IDE, wrote a tiny blink program, and it worked.A few days later, I got the ST-Link V2. I connected the SWCLK, SWDIO, GND and 3.3V terminals to the black pill as I found online, and connected the ST-Link to my computer. The LED inside the ST-Link turns on, but the PWR LED on the black pill doesn't turn on. The ST-Link is detected by the STM32CubeIDE, I also did a firmwar

Hi,     The default ADC clock source is PLL2P = 80 Mhz in my Cubemax "Clock Configuration" TAB.      I can use ADC clock Prescaller to lower it below 50 Mhz. 50Mhz is the max vale for ADC clock.      Question: The default setting PLL2P = 80Mhz before applying the ADC Prescaller is allowed or disallowed?                        If it is disallowed, how to lower PLL2P in Cubemax "Clock Configuration" TAB. without changing all other clock's default settings?         Thanks Rong     

Hi,In my next project I would like to use 2 type of displays. One with MIPI DSI interface and the other with parallel RGB.That is why I chose microcontrollers from the STM32U5 series ( vector graphics accelelator ).According to the information on the ST website, the series (100 pin):STM32U5G7VJ and U5F7VJ support RGB interface and STM32U5G9VJ and U5F9VJ support MIPI DSIHowever, inside the datasheet of the series: STM32U5F7xx in the section describing the pin layout there are 2 types of 100 pin packages:"LQFP100 SMPS" - there is no MIPI DSI pins"LQFP100 DSI SMPS" - has pins to support MIPI DSI (7,8,10,11)And now I am completely confused.The question is which STM32U5xxxx (100pin) chip should I order to support RGB and which one to support MIPI DSI ??Tomasz

Hello,I have designed a custom STM32 module using the STM32H7A3RGT6 microcontroller. In my design, PB9 is connected to an LED, and to verify the module's functionality, I attempted to toggle this LED.Here’s where the issue arises: According to the STM32H7A3RGT6 reference manual, GPIOB is connected to the AHB4 bus, meaning its peripheral clock should be enabled using RCC_AHB4ENR. The manual specifies an offset of 0x140 for this register. However, when I use this offset in my code, the LED does not toggle, suggesting that the address is incorrect.Interestingly, when I asked ChatGPT for the correct offset, it provided 0xE0—and when I used this value, the LED toggled successfully!This raises concerns about the correctness of the reference manual or suggests that I may be missing something. Could you clarify why there is a discrepancy in the RCC_AHB4ENR address?Here are my codes:GPIO_DRIVER.H Code#ifndef INC_STM32H7A3XX_GPIO_DRIVER_H_#define INC_STM32H7A3XX_GPIO_DRIVER_H_ #ifndef GPIO_

Hello,I am encountering an issue when converting a TensorFlow Dense layer to .tflite and subsequently using the ST Edge AI tool to convert it to .nb format, following the ST Edge AI Guide for MPU.When using a lower-dimensional input, the conversion succeeds. For example, the following code works as expected: input_features = tf.keras.Input(shape=(1, 384), dtype=tf.float32) output = tf.keras.layers.Dense(1536)(input_features) model = tf.keras.Model(inputs=input_features, outputs=output) However, increasing the input dimension to (1500, 384) results in the following error: ST Edge AI Core v2.0.0-20049 PASS: 0%| | 0/2 [00:00<?, ?it/s]Galcore warning: MMU is disabled!

I'm using a Nucleo-U575ZI-Q board to test Azure USBx MSC storage protocol strack against an Ubuntu-16.04 LTS host, using STM sample MSC code stripped down with a dummy interface against local storage.A Beagle USB 5000v2 is connected between host and device so that I can capture USB traffic. Enumeration works fine and host starts to talk MSC to device over ep 0x01 and 0x81, probing it for number of LUN, capacity, test-unit-ready and so forth, but no request for media transfer (rd/wr). But with 100% certianty it fails on the 24'th command which is a MSC Test-Unit-Ready.Bus analyser show that Command Transport packet is correct on the bus, and device endpoint has ACK'ed the packet. But when MCU calls HAL_PCD_IRQHandler() and reads out OTG_FS::GRXSTSP::EPNUM, it points to an unconfigured endpoint (usually 15). Also, very often, the PKTSTS field of GRXSTSP contain a value that acc.to speification is Reserved. One odd thing is that BCNT field is always 0x6b6 which is way off for what a FS bu
