Hi,how do you implement a scrollable text box? i.e. a text box where the text is too long to display in the available area so the user needs to scroll down like in a mobile phone?Is this done fully by TouchGFX or do I need to write a lot of code behind it to do the display and the scrolling?Thank you :)

Hi ST-CommunityI am working on CAN Communication in F103When I am de-initializing properly , But when , I am reinitializing it is not workingPlease tell me how to reinitialize CAN Communication if (0 == HAL_GPIO_ReadPin(BRAKE_GPIO_Port, BRAKE_Pin)) { Display.out.brake = 0x20; ControlVals.brakeStatus = 1; if (Communication.CAN_D_I == 0) { if (HAL_CAN_DeInit(&hcan) != HAL_OK) { Error_Handler(); } Communication.CAN_D_I = 1; } else { Display.out.brake = 0x00; ControlVals.brakeStatus = 0; if (Communication.CAN_D_I == 1) { if (HAL_CAN_Init(&hcan) != HAL_OK) { Error_Handler(); } Communication.CAN_D_I = 0; } } }  

I'm trying to use STPM32 with XZM-CT50A01, and the series resistor = 6.2 ohm. I thought ks = Rb/N = 6.2/1000. But I cannot measure the expected current.The load was 50mA but STPM32 respond 1.2A.The software may be OK because we have confirmed with EVALSTPM33.I'd like to know the Ks setting is correct or not. Maybe our board has already damaged, or the board has cold soldering??Can you advise me if the Ks calculation is correct?  

Hi all,I have noticed a difference between LAN8742 datasheet and the circuit on STM32F746 Discovery board.This is an extract of the schematics of the demo board:The pull-ups R90 to R93 are directly connected to "3V3"whereas in the LAN8742 datasheet (Revision 1.1 (05-21-13)) they are all connected through a ferrite to "3V3":   Was this an error of the developers of the Demo board or simply a better solution ? If in the latter case, why ?   

Dear all,does anyone have experience with setting analog output signals via Zephyr RTOS? I managed to get the D/A conversion on the Nucleo H723ZG to run via STM32CubeIDE, but I’m running intro trouble when using Zephyr. Apparently a "DAC" driver is required, however the documentation is not very clear.Thanks 

Hello,I have created my own board in zephyr (using STM32U575).Now I would like to configure the power mode pins (CSLEEP, CDSTOP, SRDSTOP ) in the devicetree of the board.I have therefore implemented the configuration for the pins in the .dts file: &pinctrl {    csleep: csleep {        pinmux = <STM32_PINMUX('A', 5, AF0)>;    };    cdstop: cdstop {        pinmux = <STM32_PINMUX('A', 6, AF0)>;    };    srdstop: srdstop {        pinmux = <STM32_PINMUX('A', 7, AF0)>;    };};However, the pins are not set correctly with this setting alone.Normally, the pins should now be assigned to a periphery.If I now assign these pins to any periphery, it works: &lpuart1 {    pinctrl-0 = <&lpuart1_tx_pa2 &lpuart1_rx_pa3 &csleep &cdstop &srdstop>;    pinctrl-names = "default";    current-speed = &l

Hello everyone !My problem is quite simple. I'm just trying to display text on the GFX01M2 LCD screen which is plugged into my NUCLEO-L452RE-P card.I created a project from STM32CubeIDE and then imported the screen drivers from the NUCLEO-U083RC + GFX01M2 example on TouchGFX.I have configured all the peripherals necessary to operate the screen (both spi, dma etc...)You will find a photo of my microcontroller configuration.I haven't found an example that uses this microcontroller. Can you help me ?THANKS :)

Hello everyone,I made a yocto based build using stm32mp1. After compiling, I followed these steps: I created 5 different partitions in the SD card. These are as follows.  I uploaded the following files to the partitions I created, respectively.sudo dd if=arm-trusted-firmware/tf-a-stm32mp157d-dk1-sdcard.stm32 of=/dev/sdb1sudo dd if=arm-trusted-firmware/tf-a-stm32mp157d-dk1-sdcard.stm32 of=/dev/sdb2sudo dd if=fip/fip-stm32mp157d-dk1-fastboot-sdcard.bin of=/dev/sdb3sudo dd if=st-image-bootfs-poky-stm32mp1.ext4 of=/dev/sdb4 bs=1Msudo dd if=core-image-minimal-stm32mp1.ext4 of=/dev/sdb5 bs=1MLater, when I connect to the DK1 board, I get the following error.When I examine the Flash layout files, I think it does this because it cannot find the FWU_MDATA files. But I don't know the size of the partitions I allocated for FWU_DATA and what type they will be (Linux file system or microsoft basic data). Can you help me with this? Which partitions are missing and what should their file typ

I have tried setup STM32G071 Sink port and connected with Apple 140w. I want to request 140W but it's seem STM32 not yet supported EPR mode in PD core. Do you have any examples for EPR in STM32?

There is no documentation provided for the REV_PARK_ANGLE_COMPENSATION_FACTOR variable in the code.hElAngle += SPD_GetInstElSpeedDpp(speedHandle)*REV_PARK_ANGLE_COMPENSATION_FACTOR;What is the purpose of this variable? i searched in the documentation but no results turned up. 

Hello, ST expert STM32F407 is used for our custom design. And htim2 play the role of precise timing base.When htim2->Instance.CNT = xx  is used for setting a new counter start value for timer2, it seems that the new counter value does not functions immediately, I mean that the next counter value does not appear one clock period later. Is there any timing diagram when TIMx_CNT register is written by user program? BRYang

Hi everyone,I'm a beginner, and this might be a basic question for many of you, but I appreciate your help nonetheless.I'm working on a project using the STM32H723VGH6 (due to size and design constraints, I can't use the ZG series) and I want to expand the RAM by connecting an IS62WV51216 SRAM. However, I noticed that in CubeMX, the FMC configuration only has a "Muxed PSRAM" option and no SRAM option (the ZG series has an SRAM option in CubeMX).Even with the PSRAM option, I found that PSRAM typically has both address lines (Ax) and data lines (Dx), but CubeMX only shows pinout for data lines, not address lines. I have a couple of questions:Is it possible to support SRAM or PSRAM with address lines? If so, how should I connect the GPIOs?If it's not possible, is there a suitable PSRAM model that fits this data-line-only configuration?When using the HAL library for development, are there any code differences between regular SRAM/PSRAM and this configuration?Thanks a lot for your help

Hello,How to clean all demo applications from OpenSTLinux, which came with the starter-package?

Good Afternoon,I am currently trying to read a text file from an NFC tag from an ST25R3916-AQET NFC reader connected to an STM32 microcontroller.I have tried to make use of the example case offered by X-NUCLEO-NFC08A1 but it only shows how to detect a tag, not how to read from it. Is there any documentation or case examples that can help or guide me to my objective? 

Hi,I am new to STM32 so this might seem a basic question... I am thinking of using one to interface to this round touch display:https://thepihut.com/products/3-4inch-dsi-round-touch-display-800x800   and ideally use TouchGFX for the UI/code.The application is a simple vending machine. And while in standby it displays a static picture (an advert or logo) and this picture needs to be updated by the local vending machine outlet through a USB pen drive or micro SD card (and needs to be a very simple process like insert the pen drive or uSD card then press a button to update)Some questions if someone could please help:1) is it possible to change the background image at runtime?2) If so, how? Do I just copy literally byte by byte the new image into the (FLASH I assume?) memory location storing the current image initially programmed by TouchGFX?3) what format (file type) is the image stored into the micro by TouchGFX initially?4) for round displays, how it the image stored? Like a s

Ask your questionWhy is the payload size not correctly written on my NDEF file?Environment :Target: STM32WB55rgTarget OS: baremetalHost OS: WindowsToolchain: STM32cubeIDELogs and console output if applicableI use it in my project NFC tag, which I read and write. I use the NDEF format for my tag. The content is something like this :Color: redSize: 2.5Length: 200.0I use X-cube-NFC-6  with the NDEF library.I have no problem reading the NFC tag. My main issue is with writing. Sometimes the library does not write the payload size in the header.Here is what I got for the correct header:E1 40 0E 01 03 29 D1 01 25 54 02And here is what I got for the wrong header :E1 40 0E 01 03 00 D1 01 25 54 02What is stranger, is that the content is correctly written.(for example, the length goes from 200.0 to 199.8 )What bothers me the most is that the writing of the header part is inside the ST library; I only pass content I went to write.Here the function to write that I use :GlobalErrorInfoCodes ST2

I have a P-NUCLEO-53L8A1 development kit, which consists of an X-NUCLEO-53L8A1 connected to NUCLEO-F401RE. When I am using the GUI program STSW-IMG041, it can correctly get data. However, I am using the X-CUBE-TOF1 kit from this website link: https://www.st.com/en/ecosystems/x-cube-tof1.html. I compiled the example '53L8A1_SimpleRanging' located in 'en.X-CUBE-TOF1\Projects\NUCLEO-F401RE\Examples\53L8A1', but I encountered an error while running it: 'VL53L8A1_RANGING_SENSOR_Init failed. Check you're using ONLY the center device soldered on the shield, NO satellite shall be connected!' I debugged my code and found that it fails when trying to read the ID:if (VL53L8CX_ReadID(&(VL53L8CXObj[Instance]), &id) != VL53L8CX_OK){ret = BSP_ERROR_COMPONENT_FAILURE;}Since using the GUI program gives me data successfully, I believe the module itself should be fine. However, I can't initialize it using the code.I look forward to receiving help from all the experts. Thank you very much.

I am trying to read multiple ADC channels using the Stm32l072 microcontroller, but in CubeMX, the options for rank assignments, which I normally use to read the channels, are not available. After manually adding these rank assignments to the init functions, I noticed that when I try to read multiple channels in normal mode, both channels show the same values, indicating that I am unable to perform multi-channel reading.I then attempted to perform this ADC reading using DMA, but observed that my reference voltage, which should be around 4095, was divided by the number of channels I was reading. For example:Number of channels to read: 4 -> VREF ADC value: 1.023Number of channels to read: 3 -> VREF ADC value: 1.365Normally, my VREF should be 3.29V, which is very close to 4090. This observation led me to realize that I am unable to read even a single channel correctly. How can I perform multiple ADC readings with this microcontroller? 

hello guys, i am using a FTDI FT232B17 for serial communicaiton with my stm32f429 board. i'm using keil uvision, and not using any libraries other than stm32f429xx.h to write the code. i am facing problems "receiving" data from the ftdi-ft232 to my STM32 board. i have successfully sent data from stm32f429 and am able to see it on tera-term/real-term etc, but i am not able to echo or receive data, any ideas where it could be wrong? i have double checked my hardware connections. while running the program when i click "send" from the Real-term, light blinks on the ft232 board but unfortunately nothing is received on stm32.

Hi,I recently created a custom board based on STM32G030 IC and programmed it via UART to run my application. Now, I want to make some changes to my firmware, but I can not connect to the CubeProgrammer. I have tried connecting it via UART and ST-LINK. Below are the errors i get when I try to connect the board via different methodsvia UART- "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... "via ST-Link- "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication". The interesting thing here is that CubeProgrammer reads the board as a Nucleo-F303RE(I am using the ST-LINK from this board and have removed the necessary jumpers i.e on CN2)I have tried to give 3.3V to pin 19(PA14) of the IC which is the Boot0 pin and restarting the board, but I am still not able to program the board. I can confirm that the IC is running the
