Hello all,I am currently working on the different combinations of LoRa Wan and found out that I-Cube-LRWAN software expansion(https://www.st.com/en/embedded-software/i-cube-lrwan.html). For the stm32l476rg, I used the sx1262dvk1das and sx1276mb1mas and it's working fine as well connected to the gateway. Now I want to use the same software expansion I-Cube-LRWAN with the nucleo-f746 as base board and sx1262. But I am not getting any reference how to achieve it.  As I don't find any "mx " in I-Cube-LRWAN projects, I am unable to do create and port to new project it's showing many errors.My queries were-1. How to port I-Cube-LRWAN software expansion from nucleo-l4 series to nucleo-f7 series?2. How to use I-Cube-LRWAN with new project?3. Why there is no cube-mx for the examples?I have been trying many examples and trying to find the solutions, but I am unable to get the solution.Thanks & Regards,Krithika. P

Hello, I want to do a boundary-scan test for a SIP module which uses ST Stellar Integration MCU SR6Gx series, how can I get its BSDL file?

HI team, I am Using NUCLEO-F439ZI board for Ethernet Interface. I successfully transferred the data in UDP, Now I try to send the data using TCP client method.  In the .ioc configuration file, I followed the below setup 1. Connectivity -> ETH -> RMII mode. 2. Middleware and Software Packs -> LWIP -> General Setting -> LWIP_DHCP (set own IP -> 192.168.1.10)  Middleware and Software Packs -> LWIP -> Key Option -> heap memory size = 10*1024 bytes.  Middleware and Software Packs -> LWIP -> HTTPD -> LWIP_HTTPD - enable after all this setup I generate the code In the Main.c file  1. by using this code I ping the connection, its works fine "extern struct netif gnetif;       ethernetif_input(&gnetif); sys_check_timeouts();". 2. from this sub function "tcp_server_init();", To create a TCP block, Bind the socket to Server Address Listen from client Accept function - connection between client and server After done

Hi, I am MURALI SELVAM from DNCL Technologies, I need reference schematic for STM32G0B1VET6 MCU, If anyone have reference schematic. Kindly provide me. Thank you.

Hello,I am trying to use ST's QSPI driver that I found in that github link. https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib/QSPI_Drivers I am using MT25QL512ABB1EW9-0SIT and when I tried to wire memory function that read it with using memorymapped I saw that first byte of my array is missing. When I increment the writing address one the problem is gone but I am trying to understand what can cause this issue.  uint8_t CSP_QSPI_WriteMemory(uint8_t* buffer, uint32_t address, uint32_t buffer_size) { QSPI_CommandTypeDef sCommand; uint32_t end_addr, current_size, current_addr; /* Calculation of the size between the write address and the end of the page */ current_addr = 0; while (current_addr <= address) { current_addr += MEMORY_PAGE_SIZE; } current_size = current_addr - address; /* Check if the size of the data is less than the remaining place in the page */ if (current_size > buffer_size) { current_size = buffer_size; } /*

Hello everyone,Currently I am using STM32F407 and trying it to interface it with esp32 using SPI protocol. Can anyone help me with that. Is it even possible or not ?

Hello,I have a use-case with a soldered battery, which I can not power-cycle after programming, however I have to set option bytes to restrict Flash reading.I found online that going into STANDBY mode or rather, returning from STANDBY mode, would update the option bytes. However, the option bytes are not set. Here is the relevant code block:    #if !defined(BOOTLOADER_DISABLE_AUTOLOCK) // Auto-enable RDP level 1 (JTAG readout protection) FLASH_OBProgramInitTypeDef option_bytes; HAL_FLASHEx_OBGetConfig(&option_bytes); if (option_bytes.RDPLevel != OB_RDP_LEVEL_1) { printf("Incorrect RDP level detected, auto locking\n"); if (HAL_FLASH_Unlock() != HAL_OK) { goto option_byte_panic; } if (HAL_FLASH_OB_Unlock() != HAL_OK) { goto option_byte_panic; } option_bytes = (FLASH_OBProgramInitTypeDef) { .OptionType = OPTIONBYTE_RDP, .RDPLevel = OB_RDP_LEVEL_1 }; if (HAL_FLASHEx_OBProgram(&option_bytes) != HAL_OK) { goto option_byte_pan

Hello, I have a guitar amp Laney LA65C where the output amp is faulty, it consists of a TDA7294 IC, I put in a new TDA7294 but it exploded as soon as the power was turned on. I checked the input voltage and it is correct 26 volts, what could cause it to explode, are there several versions of the TDA7294 with other supply voltages? There is no insulation between the circuit and the heat sink, but the heat sink has no contact with the device body.  

Hello,I am implementing a Modbus Master on a STM32F722. First, transmissions and receptions were managed through Rx/Tx interrupts. But as I got a lot of overrrun errors while getting my slave's responses, I decided to transfer received packet through DMA to my Rx buffer to avoid microcontroller's overuse. As my board is a modbus master, I use RTOR to generate an interrupt when slave finished its transfer, as adviced in STM32F7's reference manual. Here is my initialisation function:static void USART2_MspInit(UART_HandleTypeDef* uartHandle) { GPIO_InitTypeDef GPIO_InitStruct; /* USER CODE BEGIN USART2_MspInit 0 */ /* USER CODE END USART2_MspInit 0 */ /* Enable Peripheral clock */ __HAL_RCC_USART2_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENABLE(); /**USART2 GPIO Configuration PA1 ------> USART2_DE PA2 ------> USART2_TX PA3 ------> USART2_RX */ GPIO_InitStruct.Pin = Modbus_System_USART2_DE_Pin|Modbus_System_USART2_TX_Pin|Modbus_System_USART2_RX_Pin; GPIO_InitStruct

I am a the peripheral, and just got a connection event from the client.Would like to know if server side provides a feature to know if I already bonded with client , or bonding will be needed. Is there a command I can give e.g., the ConnectionHandle and will tell me if paired (yes no?)Thanks!

I purchased EVLAKIT-ROBOT-1 and am trying to run it.I request information for operation.An error occurs when building the example code.I wonder if the problem is caused by the software tool version. If so what version of software should I run it with?1. STM32CubeIDE version?2. MCWB version?

how can i do to activate the ble of stm32l4 cardI use platform io and framework = zephyr

Hello.I am creating a board with an STM32H7R3Z8J6. I am wondering what I should connect DVDD to? My intuition and "experience" says that this is the "Digital power supply pin", but it doesn't really make sense to make that distinction on this type of component, since it "digital by default", and then you have some analog parts (which you supply through VDDA).The "Getting started with hardware development for..." app not doesn't really specify much, it says that it's "Digital supply for the USB HS PHY". This indicates that it's a power supply and should thus be connected to the rest of the VDD net (or some other voltage). I am using USB on this board (D+ and D- connected to a USB connector), but I have connected both VDD50USB and VDD33USB to VDD (3.3V), which I got from some other spec.There is also a diagram:where it looks like it should be connected to the VCAP net with a 100nF cap to GND. I also found this schematic from a Nucleo board with a similar MCU, which sort of confirms

HI，     I am developing my ble audio project with STM32WBA55G-DK1. I need use SAI interface as audio input interface. I have an annoying problem. I configure RCC before init ble stack. I choose use pll1rclk as system clock. But i call the BleStack_Init function to init ble stack which provide by ST, the register of  RCC_CFGR1 changed from 0xF to 0x0, HSI16 becomes as system clock. I can't understank why the Ble stack do that。 If so that, does it mean that the maximum system clock can only be 16M when using Bluetooth function？Thanks

The ST community site is often extremely slow, even time outs occur . You access a few pages fine and then it takes a minute or more , time out or error occur.Often trying to Edit a port, it often fails with an error message. Accessing other website is no problem at all. 

Hello all, I am developing with a STM32F429bit6 by STM32CUBEIDE v1.15.1 and TouchGfx v4.23.2. The LCD display works well. The screen layout is portrait.However, when I moved the images to the SPI flash (w25q64), the display was crashed. The changes are as below:Change the ld file to store the images and fonts:  Enable External Data readeradd spi flash driver and implement the virtual function  void DataReader_WaitForReceiveDone() { return; } void DataReader_ReadData(uint32_t address24, uint8_t *buffer, uint32_t length) { W25Q_Read(address24, 0, length, buffer); } void DataReader_StartDMAReadData(uint32_t address24, uint8_t *buffer, uint32_t length) { W25Q_Read(address24, 0, length, buffer); }    

Posted on July 06, 2018 at 16:09Sorry for my stupid question, but this makes me really confused. I was just looking for the the bus with connected with the EXTI, then I found that APB2 bus is connected as it is shown in the reference manual in here : https://www.st.com/content/ccc/resource/technical/document/reference_manual/4d/ed/bc/89/b5/70/40/dc/DM00135183.pdf/files/DM00135183.pdf/jcr:content/translations/en.DM00135183.pdf so here I attach the screenshot of the datasheet But when I tried to activate the clock for APB2 bus in APB2ENR, I cannot find in what bit is the EXTI in.Then I got confused in what bus and what bit is it to activate the clock for exti. Sorry for this stupid question, by the way I am a new learner#stm-mcu #datasheet-inconsistency #stm32-interrupt

Any writes, erases or reads to flash range greater than 0x8100000 fails. When I inspect the region via Memory browser in STM32Cube IDE all memory beyond 0x8100000 appears as a "?" indicative that a read is not being allowed. Being new to this controller and STM family of devices , I'm not sure what configuration I am missing. Can you please provide any hints or tips

Hello all. Can you help me?According to the PM0269 I need to use sone API function for periodic advertising. Where is hci_le_set_periodic_advertising_data() finction? There is no hci_le_set_periodic_advertising_data() finction prototype in bluenrg_lp_api.h header file. I only saw the aci_gap_set_periodic_advertising_data() function prototype for use.Thank you for your attention. 

@John E KVAMI ported the gesture recognition example (STSW-IMG035_F401) from the STM32F401RE to the NUCLEO-U575ZI-Q with the X-NUCLEO-53L8A1 and the gesture library (STSW-IMG035_M33).  If I used the VL53LMZ_ULD_API driver included with the GestureKit it seemed to work fine; all gestures were recognized. If I used the VL53L8CX_ULD_API driver (STSW-IMG040), it worked poorly; only the TAP gesture was recognized (and even that was inconsistent).  This was repeatable on the same hardware;  I could load and calibrate the MZ based project and it worked fine, then I could load and calibrate the 8CX based project and it would only recognize the TAP gesture.  I was surprised that the driver intended for the specific part performed worse than the generic one.I've attached the two ported projects (one using the MZ driver and one using the 8CX driver) for comparison.Have I missed something? Note: One significant difference I just found was that If I held a book at about 20c

Hi all!Environment: I use MX to configure the DCMI Peripheral including DMA!MX generates MX_DMA_Init() and MX_DCMI_Init()After DCMI initialization in main with the above mentioned functions I use the functions HAL_DMA_RegisterCallback(&hdma_dcmi, HAL_DMA_XFER_CPLT_CB_ID, &DcmiDmaFullCplt) and HAL_DMA_RegisterCallback(&hdma_dcmi, HAL_DMA_XFER_HALFCPLT_CB_ID, &DcmiDmaHalfCplt) to register Halffull and Full DMA Callbacks.Both callbacks are registered in the hdma_dcmi structure. Everthing ok so far.Problem:But when I execute HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_CONTINUOUS, (uint32_t) ae_dma_buffer, AE_DMA_BUFFER_SIZE); to start the peripheral, the function overwrites the dma full function pointer. Therefore the HAL callback is used and not my dma full callback function (half full works fine). Otherwise if I try to register the callbacks after calling HAL_DCMI_Start_DMA(), the registration is refused because the hdma-->state is different to HAL_DMA_STATE_READY.So how

Hi there,I am using cubeMx and TouchGFX to show some UI.I set the display format to RGB 565 in both cubeMX LTDC and TouchGFX config.But in the generated code by touchgfx, all the images are stored by RGB888 or ARGB8888 format(in the path "TouchGFX\generated\images\src\*.cpp").Because I just need RGB565, can I just store the bit I need? Thank you.
