Hi, i would need information about setLineSpacing (int16 space) method in textarea widget.Documentation says that it's used for increasing space between lines, but the parameter "space" defines the space in pixel or other unit measurement ?Thanks a lot anyone can help me 

Hello,I am using the STM32F429I-Discovery board with an MT9M001 camera module, and I am developing with STM32CubeIDE.I would like to display the live camera image on the built-in LCD of the F429 board.I have already connected the camera and can read image data through DCMI, but I am not sure how to configure LTDC (and possibly DMA2D) to display the image in real time on the LCD.Could you please provide guidance or an example on how to:1. Configure LTDC for displaying a frame buffer2. Transfer camera image data from DCMI to the LTDC frame buffer using DMA3. Match the resolution and pixel format between camera and LCD4. Set up these peripherals correctly in STM32CubeIDEThank you for your support.

Hello team,   We are using STM32WL55 MCU. I haven't found any information about resistance value of its internal pull-down resistance. As far as I know it is typically 40k. But could you tell what is the tolerance of this value?   Best regards, Vladislav

Hello,I'm using STM32G474QET6 with HSI (16Mhz).When not using DMA - the UART is working.With DMA I'm having 2 issues:When sending 3 bytes, only 2 bytes sends.DMA is not receiving anything (UART Rx) - CNDTR remains 3 and not data is written to the buffer (data.bytes[1]).The 2nd issue is the main issue. That is my UART init func: LL_USART_InitTypeDef usart_init_struct; USART1->CR1 &= ~USART_CR1_UE; // Disable USART 1. // USART 1 clock enable. LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_USART1); usart_init_struct.BaudRate = 19200; usart_init_struct.DataWidth = LL_USART_DATAWIDTH_8B; usart_init_struct.HardwareFlowControl = LL_USART_HWCONTROL_NONE; usart_init_struct.OverSampling = LL_USART_OVERSAMPLING_16; usart_init_struct.Parity = LL_USART_PARITY_EVEN; usart_init_struct.PrescalerValue = LL_USART_PRESCALER_DIV1; usart_init_struct.StopBits = LL_USART_STOPBITS_1; usart_init_struct.TransferDirection = LL_USART_DIRECTION_TX_RX; LL_US

Hi, I'm trying to get a PWM output that changes duty cycle on each period with DMA in circular mode. I have seen other similar posts (ultimately I'd like to control a WS28 LED with 800kHz), but they are for other MCUs and everything is different in the details. I tried this for quite a while in a bigger project, so reducing it here to the bare minimum.To start with, I'm using a slower timer and just try to get the DMA to change the CCR1 at all on a dev kit (NULCEO-H563ZI)Starting of with this example: The unmodified example works and outputs a PWM on PE9 (50% DC). No I configure DMA as well:  In the main.c, I add the DMA: In my understanding, the CC event of timer1 ch1 should now trigger the DMA transfer of the samples from buf, one by one, so DC should be 10000, 50000, 10000, 50000, and so on (circular DMA).The output on the scope is unchanged, the DMA never seems to transfer anything.I also tried to use other trigger source for DMA (GPDMA1_REQUEST_TIM1_T

I'm planning to connect 40 LED with a current of 20mA (total 800mA) to 40-gpio pins of STM32G4 device. The pins will be configured as Open-drain so the 20mA LED current of each pin will flow through an external resistor and the internal low-side NMOS transistor of the IC.In this case I believe there will be no restriction about the STM32G4 power dissipation and current capabilities. This is true or am I wrong? Please could anyone clarify this?Thanks in advance,Gaston

Hello all, I disabled the M4 core based on the tutorial by ST Employee mEALLEm, I pressed Apply, saw the option byte successfully programmed notification, but I have been waiting for MCU disconnect notification for 20 minutes now. The LD4 keeps blinking greed and red. Is there something I am missing because it should not be this long ? Thank you

Hello. I'm using STM32CubeMX with STM32f777ZI MCU to create a CMAKE project.The generated linker script file (STM32F777XX_FLASH.ld) has a really simple definition of RAM memory regions:/* Specify the memory areas */MEMORY{RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 512KFLASH (rx) : ORIGIN = 0x8000000, LENGTH = 2048K}There is no separation of SRAM1, SRAM2, DTCM and etc. For example - I want to enable cache in SRAM1 and I need to have a proper section definitons. I want to use in my code something like:__attribute__((aligned(sizeof(uint32_t)), section ... and etc.Is it possible to force STM32CubeMX to generate more detailed RAM segmentation for F7 cores?

Greetings,Looking at PM0271, there seems to be an API call aci_gap_start_gen_disc_proc.  However, I don't see this in the Cube firmware package anywhere in the headers and I haven't found it in sample code as yet.   We would like to configure the STM32WB55 for dual role BLE, Central and Peripheral.  The Peripheral works.  When we enable the Central role and then send the scan_enable command, the wireless stack doesn't accept the request.  So, we figure it might be helpful to see an example. What examples are available that demonstrate BLE scanning on the STM32WB55?  I checked the AT_Client/Server. BTW, It's pretty difficult to search through samples as the IDE tends to bog down then crash.Cheers

Hello,I am trying to run Projects\System\SIUL2\siul2LedBlink from StellarSDK_4.0.0 on a SR6G7EVBC4000P_RevA board. The project was successfully build. To flash the board in RAM, I am using the last version of Lauterbach. When running, it seems that it can't break on main.For testing purposes, I was running the sieve_ram_aarch32_arm_v8r_le.elf using the same Lauterbach script and the execution and breaking on main was done as expected. On a deeper investigation, I have found out that the .elf file form Lauterbach differs from the one build. Those differences can be seen below. Also, I have tried running an example from Lauterbach using the NVM, but I get the following error:  Do you have any suggestions to run Projects\System\SIUL2\siul2LedBlink on the board? Also, to flash an application on NVM and fix the flash programming error. Thanks in advance :grinning_face:

Hello,I have a problem regarding the slow initialization of eth1 on SR6G7 evbc6000 rev B board.The function xNetworkInterfaceInitialise() is failing multiple times, until it is succesfull.  From further investigation, I discovered that phy_check_id() is the cause of the failing. phy_check_id() is used inside dp83tg720_phydev_init(), which can be found here: ModExt/Drivers/Ethernet/DP83TG720/src/dp83tg720.c .Is there something that must be done before initializing the interface? Could it be a problem regarding the Ethernet cable?This behaviour can be seen using StellarSDK 4.0.0, using the ethPing project (Projects/Comms/Ethernet/ethPing). In order to use the eth1, in main() function I also registered the eth1 interface, like this: xNetworkRegisterIf(ETH0_INSTANCE, NO_HW_LOOPBACK);xNetworkRegisterIf(ETH1_INSTANCE, NO_HW_LOOPBACK); Thanks in advance! :) 

Hello everybody.This is my first post in this forum and I am quite new to the stm32 MCUs. So sorry in advance if I dont know or misunderstand some things. Right now I am working on a setup to read values from a sensor (dps310) and print them in a console on a linux pc. I am using two Nucleo boards for this because the goal is to have a radio communication between the two boards and to remotely read the values from the sensor. Right now the boards are directly connected to each other with uart because I am doing this step by step. So the setup looks like this:Sensor --(SPI)--> Nucleo-F429ZI --(UART)--> Nucleo-F439ZI --(UART/USB)--> PCThe Nucleo-F429ZI is working fine and does exactly what it should which is to read the sensor and transmit the data about once every second to the other board.The Nucleo-F439ZI however is giving me some headaches. The idea is pretty simple. Receive the data with HAL_UART_Receive_IT() and use printf() to transmit the data to the pc in a re

Hello, We have two discovery boards with SPC5 automotive MCU - SPC560B-DIS and SPC582B-DIS.We want to use them as basis for testing our hardware, and intend first run the tests with the discovery boards.Where can I find files required for testing regarding these boards - I am looking for SVF, STAPL and BSDL files, can I download them from the website (I failed to find them) or can you send me those files? Thank you in advance,Adam

There are several R52+ cores available in Stellar SR6 P7 line, e.g. SR6P7C8.I have question about the Symmetric Multi-Processing (SMP) support on these R52+ cores. Is SMP available inside R52+ cluster or among R52+ clusters?

STM32H5 USB Custom HID CubeMX issue.When setting parameter "UX_DEVICE_CLASS_HID_EVENT_BUFFER_LENGTH" to 64 in CubeMX, the corresponding define in the "ux_user.h" file is commented out.Setting this parameter to any other valid value (between 0 and 255, excluding 64) in CubeMX generates an uncommented define.I presume CubeMX is doing this because it assumes the default value from USBX is 64 bytes.In fact a default value is provided by usbx in "ux_device_class_hid.h", but this value is actually 32 bytes.Thus, using out of the box CubeMX generated code when "UX_DEVICE_CLASS_HID_EVENT_BUFFER_LENGTH" set to 64 results in very nasty memory overwrites in the USBX device structures that subsequently result in hard fault.Please update CubeMX to not comment out this define when set to 64.Thank you.    

I have flashed the application onto the HSM core of SR6G7, and I can see that the HSM core is not running up without a trigger from the Host core. After some analysis, I found that the HSM core requires a power mode change from DRUN mode to RUN mode via the ME_MCTL register. Therefore, I would like to know how we can enable the HSM core to run first by changing the ME_MCTL register value to RUN mode directly, without running the Host core of SR6G7. I want to ensure HSM core running first before host core running. Any help would be appreciated.

I would like to know that, what are the minimum DCF configuration required to activate the HSM core in Stellar SR6G7? Is there any Lauterbach cmm script available to flash the UTEST DCF configuration? 

To enable the HSM notification to application core, I understood that we need to enable HSM2HOST IE register. I would like to know which bit position of 32 bit, we need to enable to make interrupt activate ? There is no such informations in the safety document.   

Hi Team,For SPC58EE84E7QMSAR , Need Port/Pin Mux Functionality / allocation Details for Hardware Software interface specificationThanks,Chetan

Hi,I need an accelerometer sensor that generates an interrupt on the acceleration, Let's say that the acceleration always is 9.8, it'll just generates an interrupt on 11 for example.Because all the sensor that I've tested just generates a specific interrupt on a threshold on either x, y, or z values. Which I don't really care about as much as the overall acceleration.Thanks in advance

Please help me to get full datasheet for part#STHV64SW.Is there any need for an NDA?What is the process?

I purchased the NUCLEO-L476RG and X-NUCLEO-GFX01M2 boards and connected them together.I downloaded the STM32L476 LCD Example project (I think I found in X-CUBE-DISPLAY v3.0.0 projects), compiled and loaded the code onto the NUCLEO-L476RG. The example worked great with a couple minor changes like HAL_GPIO_ReadPin(B1_GPIO_Port, B1_Pin).The provided images (.H const char arrays) displayed correctly and the text strings with various size fonts worked as well. Text strings are displayed at x/y position with selected color and background color. But when text strings are positioned over an image, there is no way to make the text character background transparent using the supplied evaluation code. I tried using the different layers of the Nucleo-GFX01M2, but only one default layer seems to be supported by the supplied software driver. See "SetLayer" below.It seems the STM32L476RG eval board cannot support two graphic layers for the Nucleo-GFX01M2, or STM did not bother

Hello Forum,I've noticed a feature/bug/behaviour in CubeMX 6.15.0 that I'm unsure about so could do with some advice.  I've been configuring an STM32U5A9ZJT 144 pin MCU for a project I'm working on.  This has been an evolutionary process.  To make the point I'll just focus on two peripherals, LPUART1 which has already been configured and I2C3 that I want to add in and configure.I start with LPUART1 configured as follows:Which has pins assigned like this on the MCU:I then enable the previously disabled I2C3 peripheral - there's nothing to say it conflicts with anything.  This results in I2C3 looking like:Having done this CubeMX silently reconfigured the LPUART1 pins.  thus:So the question is: "Is this normal?" If so I've never noticed before. It seems odd to me as I could have had a physical board made with the LPUART1 pins setup in the initial config.  Adding the I2C3 peripheral breaks LPUART1.Any thoughts/advice much appreciated.DD   &
