Hi all, I am developing a TCP server starting from the STM32F4 TCP server echo sample.My goal is to keep the echo functionality and send in addition a periodic message.I modified slightly the original file and I managed to have the echo working and the method tcp_echoserver_periodic_notification called every second, but that message does not get to my client.I am probably doing something wrong but I do not understand what since it's my first time with LwIP and I must say it's not very straightforward.Can you please help me, what am I doing wrong?Also, I see other examples using the methods pbuf_take and pbuf_alloc, but the ST example does not use them, what is best to do here?Thanks.

Hi I am using STM32H747I-DISCO board, where I am using FDCAN module, I tried with external loop back mode with FDCAN1 able to transmit and receive single message ID, but i want to transmit three message ID's and receive the data as per the message ID's. But I don't how to configure for multiple messages ID's please someone suggest any example with multiple message ID transmit and receive.

Hi,I consider the boot option for our device. Normally we boot from qSPI EEPROM. STM32MP157 has an option to boot from SLC NAND. Does SLC NAND at STM32P157 have advantages in terms of read/write speed over qSPI? Thank you in advance!

Hi,Im using stm32f103c8t6 along with w25q64 spi flash memory. I'm trying to do with this as a mass storage device but it is not working please help me with this.

Hello all,Quick question. Why does Secure Engine (SE) consume so much RAM for projects supporting KMS and X509? In sample projects, by default it's around 120 [kB] of RAM assigned for SE. For purely "building" purposes we decreased it down to 36 [kB] and it builds successfully, but still wondering why by default it's so much? PS. Yes, that question might seem dumb, but we are trying to find out what's the RAM consumption by SE.

  Hi, <1> Recently I noticed the important of the Linker setting when I configured USB support(Someone say that need to increase the value in case of going wrong).  So I am wondering how large I could set.How does it relate to System SRAM or somthing else? And how can I find it in codes? I took over a project with USB problem that was not created by CubeMX. <2>I am also a FreeRTOS new user.I was told I should set a large stack when create a task in the first time.   But how maximum I could set?  All task stack add up can not be more than what?   Does someone know or think about these questions? Thanks for your reply.

Hi,Reader IC - ST25R3916RFAL version - 2.8.0Serial interface - I2CI am trying to read the entire memory (2KB) from ST25tv16k using the api rfalNfcvPollerExtendedReadMultipleBlocks.eg:-  err = rfalNfcvPollerExtendedReadMultipleBlocks(flags, NULL, blockNum, 75, rxBuf, 2050, &rcvLen);  In the above code, I am trying to read 75 blocks. This api returns ERR_NOMEM.What is the maximum data I can read from the tag in a single fn call?Also, the code breaks if the "numOfBlocks" is more than 75 in the above api. The reason found is that this will call the function st25r3916ReadFifo() with parameter buf as NULL and it is causing issue in my code.  Why is a NULL passed here ? What is an I2C api supposed to do when a NULL is passed ?

Hello !With my TouchGFX designer, the digital widget and the analog clock widget do not work with the STM32G071 application template (at least with the simulator, I can not confirm with the board). When I say it does not work I mean it is well displayed but the value (or animation) is never updated. The widget is frozen to the original value.

Hello.I have created a project with STM32H7, and in the project, I have included TouchGFX and ThreadX.I have an external memory controlled by SPI5. Everything works correctly. However, on some occasions, the function: status = HAL_SPI_Receive(hspiDFW25, bufferRX, bytes_to_read, 1000);returns TIMEOUT.If I give higher priority to the task where the HAL_SPI_Receive function is called than to the TouchGFX task, the error occurs less frequently. However, it still persists.Any ideas?

Hello.On a custom board with STM32U535CEU6TR, I can't have HCLK set to 160 MHz. At that speed, I get random hard faults. If I set HCLK to 80 MHz, then everything is fine, no more random hard faults.On the same board, with STM32U535CEU6QTR; no problem with HCLK set to 160 MHz.Here is the MCU power supply (same for both boards revision) :Clock initialization is borrowed from CubeMX generated code : /* Init HAL */HAL_Init();/* Configure the internal regulator output voltage */__HAL_RCC_PWR_CLK_ENABLE();HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1);/* Initialize main PLL */RCC_OscInitTypeDef RCC_OscInitStruct = { 0, };RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;RCC_OscInitStruct.HSIState = RCC_HSI_ON;RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;RCC_OscInitStruct.PLL.PLLMBOOST = RCC_PLLMBOOST_DIV1;RCC_OscInitStruct.PLL.PLLM = 4;RCC_OscInitS

Hi,I'm trying to understand SPI communication for your L9963E.In the data sheet for your L9963E IC is missing the definition of how SPI shall be configured. It doesn't say anything about MSB/LSB bit send configuration for SPI. In the picture below we can see that you have defined the order for IC frame which seems to mismatch with the actual code. From the picture below we can see that CRC should be sent the first in the frame, but in your source code in AutoDevKit Studio, CRC is packed the last spiWord[4]. Probably I misinterpreted your IC frame definition or example code.Can you please explain the right order for both receiving and sending SPI frame, as well as, how should SPI be configured?

I am currently working on stm32H7B3l-EVAL having currently gotten a custom screen to work over RGB interface but I am having problems with the touch interface. The board comes with FT5336 touch controller and having tried to modify the registers to match the GOODIX-GT911 documentation. when logic analyzer is coupled on the connector the correct start address is sent but no ACK is received.I found this GT911 library on github ---https://github.com/DiveInEmbedded/GT911-Touch-driver/tree/mainI got this working on the board without touch GFX but when I try to use the library with the STM32TouchController.Cpp The inclusion of GT911.h does not give any errors but all the internal functions from GT911.c gives errors as seen in included pictures. I have tried several guides because I have a gut feeling that the tgfx touch controller file still cannot see the driver fully.is there a easy way to get external library to work with the STM32TouchController.Cpp or is there a easi

Hello,I have already seen some old post about this topic, but without a clear explanation and solution. I have the following function, to configure and enable timer with the desired period. void HW_TIMER_Enable(uint32_t period){  LL_TIM_SetAutoReload(TIM6, period);   // reset counter register and prescaler counter register  LL_TIM_GenerateEvent_UPDATE(TIM6);  LL_TIM_ClearFlag_UPDATE(TIM6);   // enable timer and update event interrupt  LL_TIM_EnableIT_UPDATE(TIM6);  LL_TIM_EnableCounter(TIM6);} If I execute this function without optimizations (-O0), it works well.But if I activate optimizations, that inlines the LL functions code in the caller, eliminating the LL functions call overhead, it doesn't work any longer.In this last case, the IRQ is triggered immediately, and not at the end of the expected period. The reason seems to be due to necessity to add a delay between the UG and the UIF clear commands.Indeed, if I add a

Hi. I am using stm32L010C6Tx. After installing the program with ST-LINK, when I turn off the power and return it, the last program I installed does not work. I need to reload the code. I wondered if it wasn't writing to your Flash, but it looks full in cubeprogrammer. The NRST lead is connected to GND with a 100 nF capacitor. Boot0 end is idle. Any ideas as to why it might be?

Hello,Using CubeIDE v1.14.1, I would like to download memory to a file, for import into a worksheet, etc.  But I've not located the ability to do that, via the IDE menus.  Is there such a capability?  I'm initially dealing with floating point values, do it'd be ideal to download to a file in that format.  But any download format would be good, and could be massaged into float format after-the-fact.Regards,Robert

Hi there, I recently purchased the B-G431B-ESC1 and when I connect it to my USB port, immediately a red flashing light appears. There are two other solid green lights. I am also not able to connect my ST-LINK to flash firmware, and this may be related. But for that I am having issues installing the necessary drivers on my Windows10 laptop. I have downloaded the relevant drivers and upon installation I am told that they were installed successfully, yet when I launch Device Manager I am not able to see them anywhere. Furthermore, when I try to launch the ST-link utility software I am told it is unable to launch because of some missing DLL files, namely mfc140.dll, VCRUNTIME140.dll, and MSVCP140.dll. With a little online research on forums I see many suggesting I reinstall Visual C++ Redistributable. So I do that just (I remove what I had and installed Visual C++ Redistributable). But it did not help at all. Any help to get me started with this board would be

Hello  everyone,It is a quite basic question, I have this stm32767zi nucleo board with a LAN driver and rj45 connector, and I intend to test the basic ping/web server examples.So for now, I do not have a router with me, so I was wondering, if I could use my laptop as a router itself , if it is connected to the WiFi and connect my board to laptop using an Ethernet cable.

So is this chip now completely released or not?The product page is available and says it is active, but it does neither offer a reference manual nor a price indication.Form what I understand it is basically a BlueNRG-LPS with more Flash. Meaning the peripherals are all BlueNRG compatible but maybe not STM32 compatible?So if I have µC drivers for e.g. I2C and UART for the L0 and WB Variants of the STM32, are those easily portable or do I start from scratch (no I do not like to use the cube drivers, but that's a different discussion)? 

Hello. I am confused about the amount of flash on an STM32F105VBT6. From the overview for the STM32F105/107 devices, I gather that this MCU should have 128 Kbytes of flash. And in STM32CubeProgrammer, in the lower right, it says that the target has 128 Kbytes of flash as well. However, I was able to program 139 Kbytes of flash, and it seems like I can successfully write 0x00000000 to the 4 bytes at 0x0803FFFC to 0x0803FFFF. So, the MCU seems to have 256 Kbytes, which is what an STM32F105VC should have. Does anyone know what's going on?

Hi,I am trying to assign Adc.Raw[0] and Adc.Raw[1] to Vref and Vtemp as in below code snippet. But, Vref and Vtemp gets 0. These variables never updated with Adc.Raw values.Could you please point me in the right direction ? 

Hi there,I was wondering if the memory used to save the values in the device registers for the VL6180X sensor are volatile or non-volatile. This would affect how the sensors behaves during a power cycle. Could someone clarify this for me if possible?Thanks in advance.
