This is regarding the issue I am currently handling. I am using STM3240G evaluation board to run a Modbus server having a TCP Raw socket-based echo server interface which receives Modbus request packets, sent from ModScan32 tool.                                                                                                                                                                The request packet is received without any errors on port 502, by the Modbus server running on the evaluation board. I am building a response Modbus packet as an array of unsigned char type, and type casting it

Hello ST experts and everyone, I am a beginner on using the STM32WLE5CC series and need some support. Currently, I have assigned to carry out verification test of STM32WLE5CC series on LORA Received Signal Strength Indicator (RSSI) and successfully set up a test system on detecting the LORA RSSI value through firmware. However, with the requirement of resource to support my test system, LORA Received Signal Strength Indicator (RSSI) accuracy (+/- ? dBm) (on receiver side) is important to verify my test system on detecting the LORA RSSI value through firmware. Therefore, I would like to ask any information or other references on it.  Would apologise that I could not provide the full design of my test system due to policy and greatly appreciate to have any support or opinion on my inquiry. Thanks. Best Regards, Jack  

I'm working with the WB55 Nucleo Transparent Mode projectIs there a simple way of changing the interface in an MXCUBE project from USART1 to LPUART1?

Hi Folks, I'm fancy of the STM32WL33. But it is yet not supported in the STM32CubeIDE 1.15.1. Is there an Add-On or when will it be supported? Thanks in advance

Hi all,I'd like to know if is ti possible to have multiple callback for interrupt. Beceause with HAL and CubeMX if I have multiple interrupt, I have only one function for callbackHAL_GPIO_EXTI_IRQHandlerexample in stm32f4xx_it.c :  void EXTI0_IRQHandler(void) { /* USER CODE BEGIN EXTI0_IRQn 0 */ /* USER CODE END EXTI0_IRQn 0 */ HAL_GPIO_EXTI_IRQHandler(B1_Pin); /* USER CODE BEGIN EXTI0_IRQn 1 */ /* USER CODE END EXTI0_IRQn 1 */ } /** * @brief This function handles EXTI line4 interrupt. */ void EXTI4_IRQHandler(void) { /* USER CODE BEGIN EXTI4_IRQn 0 */ /* USER CODE END EXTI4_IRQn 0 */ HAL_GPIO_EXTI_IRQHandler(RFM_INT_Pin); /* USER CODE BEGIN EXTI4_IRQn 1 */ /* USER CODE END EXTI4_IRQn 1 */ }  So if I want to have specific callback for EXTI4 there is a solution from CubeMx or not ?Maybe :void EXTI4_IRQHandler(void) { /* USER CODE BEGIN EXTI4_IRQn 0 */ My_callback(RFM_INT_Pin); return; /* USER CODE END EXTI4_IRQn 0 */ HAL_GPIO_EXTI_IRQHandler(RFM

Hello,I have a general question to the pin mapping and registers for the H723ZG. Where can I find the register name or register ID of e.g. the GPIO PA4? I expect something like 0000x000 or similar.I have searched for this in the DB3171 Data Brief, in the RM0468 Reference Manual and in the UM2407 User Manual (with pin-out), but this GPIO and other aren't even mentioned in the manual...So how do I access these functions, if I can't find the register numbers?Thank you Kind regards

Hi, I was trying to have microSD logging with F439 Nucleo. I can't see example with mentioned board. Please let me know:1. example for mentioned board to log data in microSD2. I tried configuring SD-4 bit, but couldn't identify the pins intialized in generated code (in MX pins used were visible)3. Tried importing F413 Nucleo e.g., but couldn't identify pins configured and wasn't able to change MCU to F439.Please guide.

Hello good day,I am using the STM32H755 Nucleo board. In the UART module, how are the FIFOs managed? According to the datasheet, there is one TX FIFO and one RX FIFO.What is the actual depth of these FIFO?

Suppose we have 50 different screen in a program.For the following modes, I have to show information to the user in a Modal window in the same screen we are in.For example, USB connection - correct storage of information in the memory - temperature crossing a certain range and...If I use Modal Window, I have to add it in all these 50 pages.:\ Is it possible to define a common Modal window for all screen?so that it can be called and shown in all of these 50 screen.

Hi,I need to prepare three modes for the certification testing.1) Always transmit modulated2) Always transmit unmodulated3) Always in receive mode.For no 1, I think I can just set the protocol as an example ISO14443 / ISO15693 then read tag, right?But I have no idea for no 2 and 3. Please help if ST25R95 is able to do it.If there is example code will be much appreciated.Thanks & Best Regards,Rezan  

Hi,HAL and LL DAC configuration structure and its parameters naming can be confusing. Reference manual claims that DAC "mode" (register ADC->MCR, bits 0..2 or 16..17) can be in one of following four combinations when not used sample and hold mode: 0 -> DAC channel2 is connected to external pin with Buffer enabled1 -> DAC channel2 is connected to external pin and to on chip peripherals with buffer enabled2 -> DAC channel2 is connected to external pin with buffer disabled3 -> DAC channel2 is connected to on chip peripherals with Buffer disabledThese combinations coherent but HAL DAC init struct offers up to six conbinations (Enable/Disable buffer times Internal/External/both connections). Some of them are not accesible. I've listed following configurations:a) - OKDAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_EXTERNAL;Resulting configuration: 0 -> DAC channel2 is connected to external pin with Buffer enabledb) - MisleadingDAC_Ou

Hi,my name is Mario and i have some troubles while debugging a program for the STEVAL-IDB008V1M eval board. ConfigurationSTEVAL-IDB008V1M evaluation boardAtollic TrueSTUDIO Version: 9.3.0In the Atollic IDE, I installed the ST-Link Utility.I compiled the original example "BLE Remote Control" (provided with STEVAL-IDB008V1M board) by means of  Atollic.I found on the net the followinf piece of advice:----It will force BlueNRG-2 DIO7 to "1" before doing a reset so that BlueNRG-2 will remain in bootloader.When trying to flash from any IDEs, you must force DIO7 to "1" before doing a HW reset or a power on / power off.----and I applied it. RESULTSIn the above conditions, the debug results are null and disappointing:for few seconds the connection with debugger seems working but it diseppears quickly: the debug process is not able to start.This is the message I got on the consoleSTMicroelectronics ST-LINK GDB server.

Hi,I have two batch of boards with STM32F437 controllers.Batch1: It takes the controller 1.2seconds to come upBatch2: It takes the controller 200msec to come upBoth the hardware and the firmware are same.In the Batch1, when the power up is done it takes 1.2second, but when I press hard-reset switch it takes only 200ms to come up. But in Batch2, it takes 200ms with power cycle or with hard reset.By toggling a gpio pin for execution of every function, we got to the point where the delay is happening. It was in the image_validation() function in the bootloader code. Here the function does a CRC check using a while loop, that is taking 970ms in batch1 boards and 120ms in batch2 board. But how can a purely software operation causes this delay?! Apart from the bootup speed, all the other functionality is working as intended.We have already thoroughly analyzed the BOM, there to no difference that was seen.The only difference I can see is that the label imprinted on the STM32 controller i

Hello. I have made a custom project with STM32H735IGT. I use Touchgfx. I am using external flash and external RAM. The problem is when I place the framebuffer in external RAM. Some green pixels appear as in image 1. When I place the framebuffer in internal RAM, the image is painted well. I am using IS66WVH16M8DBLL-100B1LI RAM. I attached hardware configuration, the RAM is OCTOSPI2.  video of the problem and .ioc: https://drive.google.com/drive/folders/1I96eqnh-5-xjDEKxfkxy-vVqeLvuVDY3?usp=sharingWhere is the problem?  

I have two SPI buses activated SPI1 (flash memory) and SPI3 (nrf24l01) on my STM32F407. Separately, they work fine. But, if I transfer something via SPI1, SPI3 read from the register always returns 0 (and in DR register for SPI3 is also 0, BUT sometimes it has value 3 (though has to be 46)). And I don't know where to look and dig dipper. Let me know if you need additional code or screenshots. 

The memory map shown on page 76 of the reference manual for the stm32f76xxx shows the following figure:I believe the addresses in blocks 5...6 are not correct and that it should be as follows:  

Hello everyone,I am an avid petalinux user. I know that STM32MP1 has had a big place in the market for many years. But I've never had to use it before. I want to use this in a project right now. And I'm a little confused about where to start. I have a few questions; 1) What exactly is openstLinux? Is it something like petalinux distribution? 2) Let's say I compile an stm32mp1 project with yocto. I couldn't find any information about how to import the resulting image files into cubeide? 3) Which of the dtb files created with cubemx should I use? 4) When I select cubeide and the mp1 family from the project opening and say "setup openstlinux", I get a manifest version error. How can I fix this? Thank you very much in advance. Kind regards    

Hi, where can I find the S2-LP chip library and examples on C. Also does STM provides any protocols with open code for frequency hopping and mesh based on sub-1 GHz external radio chip?  I've found just sw package with gui to configure radio S2-LP and only for windows. I'm also happy to read any other open source solutions with frequency hopping and mesh support if you can recommend for me. Thanks in advance
