HI, Does the STM32H563ZIT6 have built-in capability to directly convert this digital data to an analog signal for speakers without using an external CS43L22 DAC (Digital-to-Analog Converter)?

Hi I'm using the STM32H755ZI board which has the option for 1.8V DVDD (using JP5). Does switching DVDD to 1.8V from 3.3V limit the functionality of the board in any way ? Are the interfaces (CAN, I2C, SPI, UART etc) still functional at 1.8V ?  Thanks in advance for any help

please provide me the information for how to configure systick in microsecond.

HiWe've got here 3 STM32G031K8 Nucleo. 2 of them had problems with RAM access. 1 works fine at the moment.For example STM32CubeProgrammer shows by RAM DumpKeil shows STLink Utilities hangs by Access of some RAM address. Is this a known Problem?Is there a workaround?Can you replace the faulty Nucleo?  

Hi, I am new to STM32 board. I have been trying to turn on the touch LCD in STM32F29i-EVAL board but even when I I connected the board to power supply, it is simply blank white screen. I have tried configuring the pins as per mentioned in the Reference manual but no use. Can anyone help me how to configure it? Is there something I am missing? I am using Keil uVision software. Thank you.

hi,I am using Nucleog474ret6 board , and I am  measuring current across JP6(header) which is vdd section of MCU.And measuring current using digital multi meter. As  measured current value is around 1.98mA(milli Amps)  while reset the MCU.But the current value mentioned  in datasheet is around micro amps. code also erased from flash , just normally checking the current consumption of the MCU.what can be the problem , or is this correct.   thanks,srinath

Morning everybody The microcontroller on my nucleo board NUCLEO-H755ZI-Q is dead after i have used 5V external power to supply it. I don't understand why

Hello everyone!I have a problem regarding my STM32F072 MCU board that I designed: I cannot connect the board with a terminal properly. Let me explain:1. I've managed the program the board using ST-LINK V2 (Chinese version) and SWD pins.2. When I connect the board with USB to my laptop, it sees it as "USB Serial Device (COM6)", and in the events tab it says "Device install requested"3. I've configured inside CubeMX as CDC (Virtual Com port), I've also done the manual USB CDC Line coding.4. I've searched for drivers, but I found that for windows 10 (what I am currently running), I don't need further drivers in order to detect the USB...5. PuTTY won't open my terminal, with the error "device is not functioning" and TeraTerm opens a terminal, but I cannot see my messages from the code. Does anyone have any idea what I should try next?

HI,     I have a 3.5"  ILI9488 TFT LCD Without touch. I want to interface it using microcontroller with SPI Interface.,Can anyone please share ILI9488 SPI tft display 320X480 resolution interfacing with stm32 sample code.

HI community,I got my hands on a MAX22192 evaluation kit (SPI GPIO expander) , currently attempting to communicate with it. While I can receive the input status from the IC, it doesn't respond to the commands I'm sending to it through NUCLEO G474RE.The evaluation kit includes a USB dongle with its own GUI interface, which I used to capture the waveform.My SPI is clocked at 2.5 MHz, and the IC supports speeds up to 12 MHz."Communication with Nucleo G474RE (Getting input status but unresponsive to commands)@2.5MhzCommunication data with evaluation kit usb dongle (which works perfectly fine)@5MhzAs per the datasheet this is my read and write packet structureaccording to led matrix register iam trying to setl led at index 0 and in the frame 2 iam trying to readback the status this is my code  int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initia

I am using the STEVAL-STWINBX1 development board and have downloadedthe FP-SNS-DATALOG2 software to the board.I compiled and flashed the FP-SNS-DATALOG2 software to the board using the ST Cube IDE and a Segger J-Link.I am trying to use the Python GUI, I can connect to the board....But there is nothing on the screen once I have connected...Does the Python GUI work with the FP-SNS-DATALOG2 software ? At the time of flashing the software to the board, I wasn't aware of the different flash banks on the micro.  Im not sure if its related to the flash banks, but when flashing I got the the following warning which I clicked yes to...Hopefully I haven't broken anything by doing this ?I am able to use the phone app to swap firmware...   If I swap to BLEDfFw firmware (running on bank 2), the Python GUI does not even detect the device.        

Hello, I recently bought Nucleo-144 board (variant F756ZG) to one of my project. I used DFU to upload firmware and external power supply using VIN pin (7.5 VDC). It works perfect until I decided to remove ST-Link part to reduce board size. After that it won't work anymore (no Serial COM, no Ethernet). Could someone help me what I am doing wrong? Maybe I should reconfigure jumpers but I don't know which. Below I attached photo of board.Many thanks for help.

We are using STM32H743BIT6 microcontroller in our project. Which is the development board that we need to buy and use for this microcontroller for prototyping and development purpose? Can we use STM32H753I-EVAL2?

Hello.I am developing a development board (to sell to customers eventually), for which I want to have my own flashing dongle. Now, I have posted in another thread asking about the software that is in the ST-Link devices, and the response I got is that it's not available for the public.But so the SWD protocol is an open standard if I understand things correctly, developed by ARM. Is the "protocol" for flashing the STM32 chips open so that I can implement my own SWD flasher, given the SWD protocol, my binary file and the specifications on how STM32 chips are flashed with SWD?Regards,Daniel

I have the STEVAL-STWINBX1 development board and want to import the FP-SNS-DATALOG2 software into S32DS IDE so I can build and flash.Is this possible and if so how ?The user manual only mentions flashing the binary file STM32CubeProgrammer, but I would like to be able to modify the software and then flash it to the board using S32DS IDE 

Hello Support Team, I am trying to use a power bank to supply power to my STM32H743ZI2 board. I have made a modification to the jumper settings: I changed the connection of JP2 from pins 1-2 to pins 7-8 as suggested for power bank usage. However, I am encountering an issue where the LD4 LED is blinking intermittently. Could you please provide guidance on the following points: Is the jumper setting adjustment from JP2 pins 1-2 to 7-8 correct for power bank usage? What does the intermittent blinking of the LD4 LED signify? Are there any additional configurations or checks required to ensure stable operation with a power bank? Your assistance in resolving this issue would be greatly appreciated. Thank you for your support. Best regards, Wolf Sripe Additional Information: Board: STM32H743ZI2 Power Source: Power Bank Jumper Configuration: JP2 changed from pins 1-2 to 7-8 Issue: LD4 LED blinking intermittently Thank you for addressing this matter at your earliest convenience.

All I need is a simple example CAN normal mode, I been searching around but found nothing. It just for educational purpose. Appreciate for any help

Hi, Im using NUCLEO-H753ZI board and i want to send raw data to computer terminal. i tried to by using USART1. according to the schematics i can send data via USRAT1 through the USB power connection and it not working. i also tried to use USB_DEVICE to send the data but it fails again. in my last project i have used NUCLEO-U575ZI-Q and i send the data with USART1 and there were no problem at all. can someone can help?

Good morning,for a project I have to set the LTDC display type to be 8 bit for some bottleneck, but doing that on STMCubeMX for my MCU STM32H723ZGTX there are only 24, 18 and 16 bit configs available.How can I set this value to be 8 bit?Thanks for the patience

Hello,I am facing an issue when I run code in stm32f407. I am using STMCubeIDE in Mcbook pro m3 chip. Furthermore, I tried with different USB-C to USB -A adapters.  I can see the stm32f407 mounted. But, Jlink could not be connected.USB-C to USB-A Adapter from ISY: 

Hello,TLRD: I cannot connect to a STM32H747I-DISCO board using my Mac/M3.my setup is a MBP with M3 (Apple Silincon) and  MacOS Sonoma 14.4. Installed latest release of STM32CubeProgrammer and bought a STM32H747I-DISCO dev board. Connecting through a USB-C to Micro USB cable on default port CN2 (labeled STLINK-V3E USB connector) and verified that the Jp6 Jumper is set correctly to STlk.Checked on system preferences that there is a STLink under the USB tree of MacOS.The board lights up and the connect led flashes then stays green. The powe led below stays green. Nothing shows up on the touch screen.Upon launching STM32Connector I cannot connect to the board with buttons. I've tried upgrading the firmware with the corresponding button/modal dialog.Sometimes (after plugging and unplugging the USB cable) the system detects the firmware SN (it's a long string of numbers) and gives the option to update, but then fails. In the meantime the ST_Link configuration panel shows a Ser

I want to perform the bootloader on my stm32l072kzt 192kb microcontroller without the need to use serial interfaces, my idea is to download a new firmware from the cloud and then update the computer with this new firmware. However, it seems to me that he doesn't jump from bank 1 to bank 2, can you confirm and explain this to me? Furthermore, what are the ways to bootloader the stm32l072kzt 192kb microcontroller?
