Hi: What does frontPorchEntered do?If i don't have DMA, i don't have to call?Thanks !​

I think I once saw some CAD files for some of STs boards, if there are such things, where are they.

We have all SMT circuit which has BNO055 and STM32F446RET6. Currently our BNO on is not working. All we did was making our GPS module smt in our new version of our circuit and it stopped working. Is it because of our GPS module? Or it can be something else? Please help us.Schematic of GPS and BNO055:(UART and I2C pins doesn't have any other connections other than seen in the images)

Hello kind community, I'm using the STM32 chip and the LTDC module as a dedicated TFT LCD display driver. Right now I am using the NUCLEO-F767ZI for prototyping, but would like to use an STM32L4R/Px chip for the final build. I don't anticipate it being a challenge to transfer my firmware from the F7 to L4 chip but I am not sure if there is a gap in my thinking.Once I get a hold of an L4 chip, I anticipate generating the initialization code for it using STM32CubeMX then copying the code I will write for the F7 over to the L4 firmware. I haven't worked enough with STM32 MCU's but I assume these all use the same LTDC library so any modification in the code will be limited to initialization code and the rest of the LTDC related code will stay the same? I will use the same package for prototype and final build (144 LQFP) so I don't anticipate problems there as long as I stay consistent with the pin assignments/schematic. Is there any other consideration I am missing that might make this a l

I'm considering STM32G431 for a motor control project with 4 stepper motors driven by step and direction.Can all 4 steppers be controlled by using TIM1's four PWM Generation channels 1 thru 4 and be made to move by different amounts of pulses simultaneousy?Or do I need to use a separate TIMx for each motor, e.g., TIM1, TIM8, TIM2, TIM3?

Hello,I have a button with a pause icon on it in TouchGFX, and I want to know how I can change the pause icon into a play icon after it is pressed. TouchGFX only gives me an option to change the icon while the icon is being pressed.

I`m trying to read an array of about 256 units of uint16 global memory variables which are loaded from *.axf with "variables node" and to display it as Bar Chart with "chart node", the single read procedure is triggering by "button node" with topic "read". "Acq out node" configured as for st-link communication. After deploying i see "p2p connected" and click the button, the data appears in chart correctly... once. And then st-link is getting totally unable to communicate with message "not connected! SWD protocol not supported(f1)". Any other software goes unable to connect with ST-link (without USB replugging) with messages like "STlink USB communication error". Devboard MB1035B works nice and programs and debug without any errors. Other words this issue appears only in CubeMonitor. But the almost same flows.json dashboard works very good and read and write any values for ST-Link+STM32F103 thirdparty board. Is any solution at this case?

Hello.I succeeded to run my own app with SBSFU on a NUCLEO-H753ZI. But now, my app uses Lwip and differents DMAs. Then, I need these 3 MPU regions:MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStruct.BaseAddress = 0x24000000; MPU_InitStruct.Size = MPU_REGION_SIZE_512KB; MPU_InitStruct.SubRegionDisable = 0x0; MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL1; MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS; MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE; MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE; MPU_InitStruct.IsCacheable = MPU_ACCESS_NOT_CACHEABLE; MPU_InitStruct.IsBufferable = MPU_ACCESS_NOT_BUFFERABLE;   HAL_MPU_ConfigRegion(&MPU_InitStruct); /** Initializes and configures the Region and the memory to be protected */ MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER1; MPU_InitStruct.BaseAddress = 0x30040000; MPU_InitStruct.Size = MPU_REGION_SIZE_2

I wanted to implement FIR filter and FFT using Cortex M4 in Dual Core STM32H745 Device. Is there any procedure document or application note available to implement by generating from STM32Cube IDE ?Filter Coefficients can be generated from MATLAB filter Design ToolBox ? or is there any other way of doing ?

Hello,i want to program my STM32G031F4P6 chip over ST Link, but i get the error message "Can not read memory! Disable Read Out Protection and retry". Disable the Read Out Protection over the Option Bytes doesn't work. Erasing the chip also doesn't help. Can anybody help me to solve this problem?

We Ordered > 100k parts at the start of February this year: My distributor (EBV) is not even getting a confirmation date, and if something is given by ST, it is far in 2022. (Date today is August 13)ST, what is going on here? Please explain and inform your customers, so they can decide to wait or to start to execute an 'escape plan' (= going away from ST MEMS devices) Time is ticking away and we run into tremendous problems. Our stock is growing, cash flow is going down, because we can't produce due to a couple of silly ST MEMS devices that are not available. It may lead to board change, and kick out ST devices from it, I am sorry.Everybody is blaming COVID for these problems, but hey, in the electronics industry there was NO REASON at all to stop production. I have to say this that we consider this as a giant management f*ckup in the semi conductor industry in general.(Note that the parts we ordered are active parts with 'in production' status)

I have integrated the .elf file in the STM32CubeMonitor, but it does not show me the self-defined variables. I tried different variables like volatile uint32_t a = 3; volatile uint8_t b = 3; int c = 3;Does someone have an idea what i did wrong?!

Hi,I'm new to the ST family of processorers and we are currentl using the SPC58EC discovery board at the company I'm currently working at.Background:I'm trying to make an application read out and print on serial what is being sent on the CAN bus. Right now I'm using the following lines of code in the main loop: returnvalue = can_lld_receive(&CAND2, CAN_FIFO0_RXBUFFER, &rxf);   if (returnvalue == CAN_MSG_OK) { write_can_msg(0, 0, rxf.ID, rxf.data8, rxf.DLC); rxCounterPoll++; pal_lld_clearpad(PORT_F, PF_LED2);   }which works OK. I have set up the FIFO buffer to have 64 slots and when I flood the CAN bus with messages using busmaster the FIFO buffer seems to be working.To my issue: when I fill up the FIFO buffer it seems like the above lines of code does not empty it when I stop flooding the bus. After filling up the buffer if I wait a couple of seconds and then start sending a new message one by one, can_lld_receive executes still the old messag

I've created my own differential AAT board (3 turn 80x36mm antenna) that is working, but with a range of only 4cm compared to the NFC06A1 range of 8cm using a similar 15693 tag . With my own board powered off, I used my miniVNA to measure the matching network and antenna and see a minimum VSWR 2.365 and matching frequency of 16.52 MHz. When I measure the Nucleo NFC06A1 it yields a VSWR of 3.727 and a matching frequency of 13.3192. When I use QUCs to simulate my board with the same matching components its different (more capacitive on the smith chart). I was hoping the QUCS simulation would be more inline with what I'm seeing with the miniVNA. Which is more trustworthy, QUCS or the miniVNA for tweaking the matching network? I've attached some charts to show the differences. Any suggestions of how to proceed would be much appreciated. Thanks

Hi all,I have small query around u-boot.How can i update my custom boot screen for the u-boot?How can add my custom application to start post boot?Thanks.

I am using the STM32L4R9ZIJ6 but do not use the DSI Host function. Can the following DSI function pins be left unconnected if the DSI function is not used:DSI_CKN, DSI_CKPDSI_DS__D0N, DSI_D0PDSI_D1N, DSI_D1PThe STM32L4R9 data sheet DS12023 Rev 5, table 15 refers to note (3) for these pins. However Note (3) details the requirement for NC balls

I'm working with the NUCLEO-WL55jc1 board and I have one strange behavior. I need one output pin and I've called it Trigger.Initially, the pin PC2 was used but I wasn't able to make it work. It had incorrect output voltages and some bounce like it was a switch. Other pins, like LEDs on the board, worked as aspected, so I decided to change the pin with PB1, using the same software: it was working.In order to investigate, I've used both outputs, the same software, just a set, and a reset after delay. I've connected the oscilloscope to see the output signal reported in the picture. Tack yellow is the PB1 output (Trigger_pin), track blue is the PC2 output (Test_pin) the wrong one. My simple code. uint16_t Distance(void) {   uint16_t distanza = 0;   UTIL_LPM_Mode_t lpm_stat = UTIL_LPM_GetMode(); // UTIL_LPM_S APP_LOG(TS_OFF, VLEVEL_H, "\r\n###### ========== PASSO ==========, %d\r\n", lpm_stat); BSP_LED_On(LED_BLUE) ; HAL_GPIO_WritePin(Trigger_GPIO_Port, Trigger_Pin, GPIO

Hello,I am trying to get familiar with vitualUart between A7 et M4 side.The example OpenAMP_tty_Echo given in the wiki works well with my setup.Next step i would like to replace the "echo "msg" > /dev/ttyRPMG0" terminal commands" by a C linux user space application by using Read/Write file operations.Writing operations work OK but i am struggling to get the Echo with read operation.No change made on the M4 echo example.Below an extract of my GTK c programWhen read operation is reached the program blocks despite the timeout settings.But when I echo the M4 with a terminal M4 is still alive. And a very interresting thing is that this echo gives also the caracteres sent with my GTK c app.I did not find any example on the web for this task.Thank you by advance for any help.Regard serial_port = open("/dev/ttyRPMSG0", O_RDWR); struct termios SerialPortSettings;    tcgetattr(serial_port, &SerialPortSettings); SerialPortSettings.c_cc[VTIME] = 10; w

STM32L4Q5VGTxP I use the board I made.FUNC 1) HAL_SPI_Transmit(ILI9341_SPI_Handle,&data,1,100);The output waveform is observed with SCLK / MOSI PIN.FUNC 2) HAL_SPI_Transmit_DMA(ILI9341_SPI_Handle,&data,1);Output waveform does not appear with SCLK / MOSI PIN.After executing HAL_SPI_Transmit_DMA once(check function)HAL_SPI_StateTypeDef err;err = HAL_SPI_GetState(ILI9341_SPI_Handle);while(err != HAL_SPI_STATE_READY){err = HAL_SPI_GetState(&hspi1);}The result continues to return err (HAL_SPI_STATE_BUSY_TX).Below is a picture of CUMEMX setup.  //======================== PSHAL_ADC_Start_DMA(&hadc1,&adc_dma_buffer[0], 4);Also, it doesn't work.What did I miss, where did I go wrong?

So we have "Over Current Protection" part in Motor Control Workbench . but it seems it needs an external circuit on board to sense current , and there is 2 question here :1- what circuit should I use and where should the output of that circuit be connected ( in "Over Current Protection" dialogue there is no place to choose a pin for over current detection .2- why we should use an external extra circuit for current sensing when we already have three shunt on our MOSFETs ? Can we add just a simple if where we measure Ia or Ib and check if this value has been passed just stop anything ? ( I've already did it and it seems to work -But I know it should be a trigger to TIM break input to work properly - So is there any easy way to do this protection by just comparing Ia and Ib ? )

Hello everyone!I want to create a TouchGFX project using IAR Workbench. When creating the code with the STM32CubeMX software, I chose EWARM. But when I open the project with IAR workbench, in the workspace there is no gui and generated folder (I want to program in ScreenModel, ScreenPresenter, ScreenView user files in the gui folder).So how to add generated and gui folders to my project, please give me advice!Thanks everyone!

I have an application which requires I count the amount of inventory in a silo. The inventory i am counting are cigarette packs that are wrapped in cellophane. They are stacked in a metal silo where the packs fit neatly up against all 4 walls. I am taking the measurement from the roof of the silo looking down at the top most pack and calculating the distance. I am then using that distance to derive how many packs are left in the stack. the range I am working with is 4cm to 26cm. My issue is the following. The distance reading I get is not stable. If I take a pack and flip it over I can get 2 different values. The difference in values can be so large that in some instances I can completely remove the pack and the range wont change. When i try to place a white paper on top of the pack the values change again however the the readings are far more stable. This issue does not effect all packs as some can be flipped and the ranges stay constant. I have also tried to spray paint the silo wall
