Hello ST Community,I am currently working on a project to design an Ethernet-to-CAN Gateway and implement Automotive Ethernet (SOME/IP) functionality over it. The objective is to enable seamless communication between CAN FD networks and Ethernet-based automotive systems, which are increasingly prevalent in modern vehicles.Key Goals:Hardware Implementation:Use an STM32 microcontroller as the core of the gateway.Integrate an Ethernet module (e.g., W5500 or built-in equivalent ) for Ethernet connectivity.Interface with a CAN controller (e.g., MCP2515 or built-in CAN FD support) for CAN communication.Software Implementation:Implement SOME/IP stack for communication over Automotive Ethernet.Develop a reliable protocol for bridging CAN FD and Ethernet communication.Challenges:Optimizing performance to handle real-time data transmission across both interfaces.Ensuring compatibility with existing Automotive Ethernet standards.Minimizing latency and addressing error handling across the gateway.

Can anyone explain to me what is wrong in my code?Microcontroller: STM32C031K6T6I'm trying to make an interface so that the user can change the name of their environment in real time, my idea and what I tried to write is something that holds the previous strings (which may already be edited) in RAM, makes the modifications and then then write in flash again. Currently my code is like this, it shows the environments ("AMBIENTE  01...24"), I can edit the name of the string, it "saves" when i call Grava();, but when I turn my board off and on the changes do not continue... I tried to copy the txtL strings to b_txtL using memcpy, and strncpy at the beginning of main();, but when i do this my my display goes "crazy" showing the strings "AMBIENTE ..." all broken in line 1 and 2Note: I can't debug and at the same time see the changes that happen on the display because the SWCLK pin was used for a display pin, I had to implement a code that erased the memory after holding d

Dear ST,Is there any roadmap for the next release of OpenSTLinux based on latest LTS kernel 6.6 ?Thanks in advancePatrick

Hi,I am trying to connect 24bit RGB 480x272 display with stm32h723zgt6 but i have pin shortage due to many pin assigned for other purpose  and earlier i used FSMC 16bit RGB  display .16bit @ RGB565 LTDC Display mainly i  need to have lower memory consumption .Most of online seller having the 24bit RGB and i couldn't find any one having for 16bit @ RGB565 LTDC.Can any one please suggest me from where i can find the 16bit @ RGB565 LTDC. Any specific model or Maker ? .

Hi, I'm using MCSDK 5.Y.2 and STSPIN32G4 on a custom board. (this is a software thing !)I couldn't find a way to get two (more than one) converted ADC Values using a single request using the RCM.So I carried on converting each channel sequentially.I made two Registrationslike so  void User_ADC_Init(void) { RegConv_t FES_ADC = {hadc2.Instance,MC_ADC_CHANNEL_7,ADC_SAMPLETIME_2CYCLES_5}; FEShandle = RCM_RegisterRegConv(&FES_ADC); RegConv_t TRTL_ADC = {hadc2.Instance,MC_ADC_CHANNEL_8,ADC_SAMPLETIME_2CYCLES_5}; TRTLhandle = RCM_RegisterRegConv(&TRTL_ADC); }  But started with converting just one of the channels  void User_ADC_Conv(void) { switch( RCM_GetUserConvState()) { case RCM_USERCONV_IDLE : RCM_RequestUserConv(FEShandle); break; case RCM_USERCONV_REQUESTED : break; case RCM_USERCONV_EOC : FES_Datum = RCM_GetUserConv(); break; } /* switch( RCM_GetUserConvState()) { case RCM_USERCONV_IDLE : if(adcSelect ==

I am trying to use pin PA8 as a PWM output using timer 1 on channel 1 for a stm32f103rct6. I have successfully programmed pins PA9, PA10, and PA11 to provide PWM output on channels 2, 3, and 4, but when I do the same for PA8 on channel 1, I do not get any output. I am pretty sure that the pin works because if I manually toggle it on and off it works fine.Is there something special about this particular pin? I do see that that pin can be configured as MCO and if I do that, I do see an 8mhz signal. But when I am using it for PWM is is not configured in that way.Could there be some kind of conflict with other pins? Any insight would be appreciated.Thanks.

Hello,I have successfully setup a virtual port and communicate from WebUSB/WebSerial and plain serial ports with my STM32F373.  I'm now looking to implement Bluetooth to eliminate the need for a USB cable.  What is the simplest way to add a bluetooth Virtual Serial Port similar to how it is done via USB?  I can also use a bluetooth hardware driver instead of a Virtual Serial Port type link as well if that is what is required.Thank you

Hello ,  I am using the STM32G0C1RET6 MCU and want to generate the frequency in between 20Khz to 200Khz, with dutycyle in between 1 to 100%, but frequency below 10 percent is not generating, as my CCR value gets 0, due to low ARR value. Am I going in right direction or not I am not getting it, and if have understood the correct use of CCR and ARR registers. here is a snippet of my code I am using, for setting the frequency I am using this logic case TIMER1: if (freq_input > 100000) TIM1->PSC = 32-1; else TIM1->PSC = 64-1; new_arr = (HAL_RCC_GetHCLKFreq() / (freq_input * TIM1->PSC)) - 1; TIM1->ARR=new_arr; for setting Dutycycle i am using, uint32_t CCR = ((duty_input) * new_arr) /100 ; switch(timer) { case TIMER1: if (channel == 1) TIM1->CCR1=CCR; here, HAL_RCC_GetHCLKFreq = 64MHz. here using the less or higher prescalar affects the frequency, so i chose accordingly.

Hi STI generally appreciate your tools and how to keep on make them better, keeping also quality on track.But let me say this: It is highly annoying that it is mandatory to login in the CubeMX and CubeIDE.Please remove this again.Use case: as a embedded SW developer I give my CubeMX project to the HW developer for review. For this short task he does not want to create a login. This is highly annoying and I request to remove this again.Please understand that for development this is just an additional work where people will rather not use the tool than create a login.If login is required for the download: ok. But let the devleoper decide whether he wants to download on its own or via the tool. No login should be needed to use the tools.Thanks for your undestanding.Led

Please look at the screen shot:I presume that the NUCLEO-H7S3L8 is equipped with a STM32H7S3L8H MCU... This is also what I can read on the MCU.Thank you.

Hi,I'm trying to use SPI Tx DMA transfer on a Nucleo STM32H563ZI board connected to a LCD module that works on 3wire spi, so just 1Tx line. I know the SPI configuration and code for the LCD driver is OK because everything works if I run in interrupt mode but when trying to send data over SPI DMA it fails.My SPI and DMA configuration looks like this. __HAL_RCC_GPDMA1_CLK_ENABLE(); /* SPI1 GPDMA Init */ target_hgpdma1_spi1_tx.Instance = GPDMA1_Channel0; target_hgpdma1_spi1_tx.Init.Request = GPDMA1_REQUEST_SPI1_TX; target_hgpdma1_spi1_tx.Init.BlkHWRequest = DMA_BREQ_SINGLE_BURST; target_hgpdma1_spi1_tx.Init.Direction = DMA_MEMORY_TO_PERIPH; target_hgpdma1_spi1_tx.Init.SrcInc = DMA_SINC_INCREMENTED; target_hgpdma1_spi1_tx.Init.DestInc = DMA_DINC_FIXED; target_hgpdma1_spi1_tx.Init.SrcDataWidth = DMA_SRC_DATAWIDTH_HALFWORD; target_hgpdma1_spi1_tx.Init.DestDataWidth = DMA_DEST_DATAWIDTH_HALFWORD; target_hgpdma1_spi1_tx.Init.Priority = DMA_LOW_PRIORITY_HIGH_WEIGHT; target_hgpdma1_s

Hi,I'm trying the STAIoT Craft platform and I'm having issues trying out the IoT Systems.So far I've tried cloning and deploying two samples:Smart Asset TrackingHuman Activity RecognitionThis is my setup:Google Chrome Version 130.0.6723.1 18 (Official Build) (64-bit)SensorTileBox.Pro (with SD Card)Rapsberry Model 4B 8GB RAM (32 GB SD Card for OS)edge_gateway_production_20241107_1_2_0.imgWi-FiI cloned the sample projects from the STAIoT Craft Homepage and just tried them out. I followed the instructions for deployment (flashing the sensortile, downloading Raspberry OS and configurations...) as described by the step-by-step procedure. This is a screenshot of the issue with the Smart Asset Tracking sample:I tried clicking on "Apply Manifest" but it didn't change the results: Just to be sure, I tried the Human Activity Recognition sample, with the same result: The only thing that is not clear to me (but I tried both ways) is if SensorTile and Raspberry have to be ON before I

Hi,i want to send sensor values from my STM to my Homeassistant via zigbee.Therefore I have configured a temperature sensor cluster at one endpoint and because my device should also control LEDs, I have an onoff cluster.I have tried to send my sensordata with  ZbZclAttrIntegerWrite(zigbee_app_info.temperature_meas_server_2, ZCL_WC_MEAS_ATTR_MEAS_VAL, 12); As a start, i places this line into the "onOff_server_1_on" function, so that I could see, when I send an on command from my Homeassistant, the temperature gets send, which also works fine.However, I tried calling the function with an external set routine cyclic (every 10s) from my ISR, which did not work and caused my processor to crash. Can anybody see a reason for that? I also attachted my app_zigbee.c here.Thanks

i have looked everywhere and cant find the datasheet for this mcu, we get alot of this becouse we are in the business of reusing dismantled ev car batteries and as much components as possible.with this we are building Energy storages for grid services. can i please get some help to find this datasheet? SPC58VX829348

 Hi STM32 Team,I am working with the STM32F7508-DK development board and interfacing it with an SD card using the SDMMC peripheral. The 1-bit data transfer mode works flawlessly, but when switching to 4-bit mode, the interface fails to operate as expected. Please guide me to resolve this issue.  Thanks and Regards,A. Ajith Kumar

Using the Zigbee stack as a coordinator, is there a callback available to notify when a new device is associated in the network?We observe the following in the M0 log:[M0] [00000015.076][PLATFORM] nwk_handle_assoc : Association accepted, sending response (0xb0dc, 0xa4c1383054f9cec1)We can detect the new device in the ZB_NWK_NIB_ID_NeighborTable, but having a callback to trigger on association would be very helpful. I've checked the documentation and examples but haven’t found any information on this.Thank you! 

HelloI'm working on a 320x240 SPI LCD using partial frame buffer strategyThe number of blocks is configured to 2 and the block size is configured to 19200 bytes.The problem is that flushFrameBuffer draws only 240x20 pixels at a time, however I would expect it to draw 240x40 at a time (240x40x2(16-bits) = 19200 bytes)Does anybody know if that's a TouchGFX limitation, or it can be changed ?

Hello,I need the BSD-File for STM32L151RCT6 for Boundary Scan. Does anyone know, where I can get it? In the recources section I can only find an older .zip file with bsd files for other processors.Thanks.

It seems that STM32H563MI has four I2C ( I2C1 ~ I2C4):However, the corresponding STM32H563.svd only includes 2 I2C ( I2C1 ~ I2C2).https://stm32-rs.github.io/stm32-rs/STM32H563.html 

SEE EDITI am using the STM32H7B3I-DK. I am trying to write my own simple SPI ISR to handle transmitting and receiving of just one byte I have gotten the slave working with my ISR (while master used HAL). I am now implementing on the master and having issues with the transmit. When I am in debug mode and transmit one byte then hit a breakpoint it works fine. However, when I just run normal after I start transmitting, my board says it starts receiving button presses. It is acting as if someone is randomly pressing all the buttons connected on the PC2 (input- pull down - active High) line. The weird thing is I don't have this issue if I use the HAL Transmit, only when I use my transmit. This occurs even if the slave is not on and the master is just sending bytes to a non powered device.My SPI Setup uses SPI2 which PC2 could have the AF SPI2 MISO but I do not have it configured that way. Could the spi be interfering with the GPIO input internally? Any other suggestions to try? SP

I have a custom board, which uses STM32H747IXH6 and MB1166 LCD screen from the related discovery board. I am trying to get TouchGFX up and running on this custom setup, but in my PCB design, I missed out the dedicated TE pin in the connector (I'm following the RaspberryPi DSI convention of DSI CLK, Data Lanes and I2C only). I can initialise the display, but I cannot get my TouchGFX application running.
