Hi Team,I need your suggestion before the design is freeze as per specification. The existing STM32G series design is still taking more current and couldn't meet our tracking application with long battery life.My application is a tracking solution.gps,lte 4g,ble,adc, battery fuel gauge, external power supply, adc, aes encryption, external spi flash for memory, i2c sensors and fota supportbased on above requirements need a long-life battery with very low power mcu recommendations.please suggest the right part series considering the cost.regards,anil

Hi,I need to configure DMA for the Rx path of my USART data. I was able to get the Tx path going correctly following this thread: https://community.st.com/t5/stm32cubeide-mcus/problem-adding-usart3-functionality-to-lwip-http-server-netconn/m-p/668703#M26841Now for the Rx path, the DMA gets setup in HAL_UART_MspInit() & this was copied as generated by CubeMX, i.e. and it's working on the other project (with CubeMX enabled) fine:else if(huart->Instance==USART3){/* Peripheral clock enable */__HAL_RCC_USART3_CLK_ENABLE();__HAL_RCC_GPIOD_CLK_ENABLE();/**USART3 GPIO ConfigurationPD8 ------> USART3_TXPD9 ------> USART3_RX*/GPIO_InitStruct.Pin = XZaber_TX_Pin|XZaber_RX_Pin;GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;GPIO_InitStruct.Pull = GPIO_NOPULL;GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;GPIO_InitStruct.Alternate = GPIO_AF7_USART3;HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);/* USART3 DMA Init *//* USART3_RX Init */hdma_usart3_rx.Instance = DMA1_Stream1;hdma_usart3_rx.In

Hey all, I'm attempting to implement the EEPROM emulation library into a pre-existing project with little success. I've added the eeprom.c file to the project as well as the header include to the main.c but even prior to implementing the code, attempting to compile/build throws an error that the "FLASH_Status" identifier is undefined. This variable is found inside the stm32f10x_flash header. I've added it from the StdPeriph file into the project but the compiler can't seem to locate it.  This process if fairly new to be so I presume I'm missing some simple step to implement the library, any assistance would be appreciated.  processor is an STM32F103programming in IAR Embedded Workbench

Hey all,I've been losing my mind over this error message that generates right on the while(1) line. it says "undefined reference to `SX1276' ", but SX1276 is defined in the PV section. Before, I defined it right after int main(void) {, but still got the same error. Any idea what's going on here?Here is the main file:  /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes ---------------

Hello all,   I am using the CAN protocol to read and write data from the Flash memory of one STM32F446ZET6 board to the Flash memory of another STM32F446ZET6 board. I have tried multiple baud rates. All working properly. However, I notice a 25 ms delay between every CAN frame, regardless of the baud rate.  Is this a default setting and/or is there a way to change this time delay?   Thanks! 

Hello world. This is my first post to the forum so please be tolerant if I inadvertently breach local etiquette. I have some experience with RPi, Mbed and Arduino systems but none with the STM32F range until very recently when I was given a few kits to play with. Unfortunately absolutely no documentation was provided with any of them. The STM32F769I-EVAL will serve as an initial example, as that is the one with which I have been playing for a few hours. It powers up and displays lights, some of which flash under certain circumstances, and sometimes appears as a USB disk drive on the development computer. That drive contains precisely one file. A vast range of documentation is available and I have downloaded a selection, along with development software. I am using a Ubuntu 23.10 amd64 system; The IDE fires up correctly, as far as I can tell. However, no documentation yet found is at a sufficiently basic level to enable me to make use of the material I do have. Neither have I yet found a

Hi, I'm having troubles to add USART communication to the LwIP_HTTP_Server_Netconn_RTOS demo from ST. I need to add communications using USART1 & USART3 to the example but have been stuck with HAL_UART_Transmit() returning 3. I came up with a little example to show the issue I'm facing:Can someone help out?I want to use pins PD8 for Tx and PD9 for Rx (STM32F439ZI) but have not found where this would be set and I suspect that PB10 & PB11 are being used by mistake (and may conflict with ETH_MII_RX & ETH_MII_TX).Thanks!int uart_test(void){int rv = OK;char cmd[ZABER_STR_LEN]={0};enum zaber_dev dev = ZAB_BOTH;huart3.Instance = USART3;huart3.Init.BaudRate = 115200;huart3.Init.WordLength = UART_WORDLENGTH_8B;huart3.Init.StopBits = UART_STOPBITS_1;huart3.Init.Parity = UART_PARITY_NONE;huart3.Init.HwFlowCtl = UART_HWCONTROL_NONE; // No hardware flow controlhuart3.Init.Mode = UART_MODE_TX_RX; // Full-duplex modeif (HAL_UART_Init(&huart3) != HAL_OK){Error_Handler();

How much time st needs to process an order. Since I ordered a nucleo board at 24th April and it is still processing 

Developing on an STM32H563ZI chip with Cube IDE and ST-Link V2.  DEBUG is configured as JTAG with Trace Syncro (4 bits), which is 4-wire JTAG (JTMS, JTCK, JTDI, and JTDO).  My project has allocated pin PB4(NJTRST) as a GPIO.  If left unconfigured, debugging is possible.  If configured as an output, the debugger loses its connection to the core with the execution of the line of code that configures the pin as an output.Why does this happen, when I'm using 4-wire JTAG?  The NJTRST line doesn't even go to the JTAG header, so it's not like the ST-Link is "secretly" using that wire.Is there maybe some option bit I need to set to make the chip happy in debug mode with NJTRST configured as a general-purpose output? 

Hi there!the lastest update of  CubeMX 6.11.0 invalidates rhe ADC settings for ADC3.ChannelTS=ADC_CHANNEL_TEMPSENSORADC3.ChannelVBAT=ADC_CHANNEL_VBATADC3.ChannelVREF=ADC_CHANNEL_VREFINTpre-updateMxCube.Version=6.10.0MxDb.Version=DB.6.0.100ProjectManager.FirmwarePackage=STM32Cube FW_H7 V1.11.1update toMxCube.Version=6.11.0MxDb.Version=DB.6.0.110ProjectManager.FirmwarePackage=STM32Cube FW_H7 V1.11.2 Cheers! 

Ops!!!  The latest firmware does support internal channel selection on ADC3.I verified that the previous firmware V1.11.1 gives visibility to the ADC3 internal channels for VBat, Temperature, and RBUF.  But if the firmware is migrated to V1.11.2 those selections disappear.Screen shot from V1.11.2: After migration.Before migration (V1.11.1): I have also verified that starting a new project from scratch using any STM32H743 automatically applies V1.11.2 to start and once this happens, the internal channels are no longer available if if you change the firmware back to V1.11.1.  

HiAs i can see your eSIMs come with Truphone preinstalled, so i wonder if its possible to use differrent provider.And if it is, how can you do so on examle of B-L462CELL1

Hi guys,I'm trying to use STM32 as a host for a HID keyboard and mouse.I have 2 wireless mouses to test (Logitech M560, HP Spectre 700), Logitech T-BC21 wired trackball, some low-end keyboard. I'm connecting them via micro-USB to USB converter that works properly with my old tablet.LED near USB port on NUCLEO lights up, looks like it enumerates my all test devices (function returns OK), but I'm always getting stuck in USBH_HID_POLL state and I never get this condition true (after pressing keys, moving or clicking mouses):  // usbh_hid.c USBH_HID_Process(...) function if (USBH_LL_GetURBState(phost, HID_Handle->InPipe) == USBH_URB_DONE)  I'm following this tutorial from ControllersTech, that basically just uses generated code, except that I'm using FreeRTOS. USB interrupt is enabled (can't be turned off in code generator).I'm powering NUCLEO from my PC USB port (programming/debugging). I have not tried to power the board from external 5V supply, but I don

Posted on February 09, 2017 at 02:08I've got a custom board with a STM32F103 that connects to a micro SD card using 1 bit SDIO. I've generated some basic test code using STM32CubeMx Rev 4.19.0 and STM32CubeF1 release 1.4.0 (both the latest according to the software & ST website). All it does it try to write a test file to the SD card.I've got a scope on the SDIO_CMD, SDIO_CK and SDIO_D0 lines to see what is happening - and the answer is 'not enough'!I can see the CMD0 command being clocked out - checksum matches the SDIO specs - at 162kHz. But the card doesn't respond. I then see the CMD8 command clocked out, again no response. And then I see CMD55 clocked out with no response. At this point stm32f1xx_hal_sd.c gives up in the SD_PowerON() function because it needed a response to that one (it doesn't seem to care too much about the rest).I have no idea why the card doesn't respond. I've double/triple checked the pinout on the socket is correct and the card pins are c

What is the procedure to flush Tx and Rx FIFOs when using SPI DMA in STM32H563ZI?

Hi, I have a suctom board with st25dv schip and i want to use EH for powering it. By default, EH_MODE is ON_DEMAND and I want to change it to ST25DV_EH_ACTIVE_AFTER_BOOT like as at on the devkit, but after writing using SMARTAG1_NFCTAG_WriteEHMode(SMARTAG1_NFCTAG_INSTANCE, ST25DV_EH_ACTIVE_AFTER_BOOT) command the value of the register doesn't changed. Datasheet says that I must use security mode for writing static config register, but how can I enter to this mode?Thanks

Hi Team,Can I use 2 ADCs of same channel configured in same ADC PIN PA3 pin where ADC-1 is at 1KHz trigger timer in timer1 and ADC-2 at 2KHz trigger timer in timer3.

Can anybody suggest a pin compatible ST micro that has more Flash and RAM than the STM32F215ZG - this has 1MB Flash and 256Kb of RAM. I have to maintain large data structures and I keep running out of space.

Hello:I am using the ST25 Dynamic NFC for energy harvesting applications in its batterless mode. I think there is a power management unit in the circuit but without energy storage such as a capacitor, is that right? If so, I need to add an external capacitor for this purpose. Could you help to explain how to choose the capacitor for energy storage and discharging for application?Looking forward to hearing from you.Kind regardsFengzhou

What code works for the STM32L412 device?I want to load an RTC calibration value into flash memory and retrieve it on subsequent running of the firmware. I've got the reading of specific calibration values working in a different IC, for ADC calibration, ICTempCal1 = (*((volatile uint16_t*)(0x1FF8007A))); Will this work with the L412 IC? But I cannot get programming of a page to work. I tried 'HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 0x080E0000,1000);'But that fails within the routine. I'm assuming the Erase routine worked, but I haven't got far enough to check. I tried the 'STM32CubeL4/Projects/NUCLEO-L4P5ZG/Examples/FLASH/FLASH_FastProgram' code and found it to fail in the last section, the GetBank routine.Different IC also. Can anyone give me the code for these operations? 

Hi, I am Murali Selvam from India, I have a doubt, Can we interface the external Micro-SD card through below given MCU, You have any reference schematic kindly give me. Thank you. STM32G0B1KBU6,STM32G0B1KET6

I'm currently using the stm32f407g-disc1 and reading an audio input through PMOD I2S2. I've carried out some examples and the hardware is working fine (writing data from the rx to the tx buffer) such as the code below. ```for (int i=0; i<BUFFER_LENGTH*4; i=i+4) {txBuf[i] = rxBuf[i];txBuf[i+1] = rxBuf[i+1];txBuf[i+2] = 0;txBuf[i+3] = 0;}``` I now wish to perform the FFT on this incoming buffer, manipulate it (my first aim is to implement a pitch shifting algorithm) and perform the IFFT again. Thus I've tried the following: ```for (int i=0; i<BUFFER_LENGTH*4; i=i+4) {fft_in_buf[fft_in_ptr] = (float) ((int) (rxBuf[i]<<16)|rxBuf[i+1]);fft_in_ptr++;} arm_rfft_fast_f32(&fft_handler, fft_in_buf, fft_out_buf, 0);arm_rfft_fast_f32(&fft_handler, fft_out_buf, fft_in_buf, 1); fft_in_ptr = 0; for (int i=0; i<BUFFER_LENGTH*4; i=i+4) {        txBuf[i] = (fft_in_buf[fft_in_ptr] >> 16) & 0xFF; // MSB     

Hi team,I am trying to implement FreeRTOS on nucleo32 board (stm32f303k8) on building the same with the one FreeRTOS task, I am getting a error that RAM overflowed by 66456 bytes.It can be resolved or I need to go with some other high memory boards? 

Hello, I am using STM32U585 TFM architecture for one of my project. Which basically is a combined project of 5 internal projects as usual TFM(mentioned below).1. TFM_Appli_NonSecure2. TFM_Appli_Secure3. TFM_Loader_NonSecure4. TFM_Loader_Secure5. TFM_SBSFU_Boot I have surpassed available RAM(SRAM1 of 192kb) for TFM_Appli_NonSecure project. And I am not getting any solution to this even after trying some ways like using SRAM3(mainly).I think now I need some export opinion for increasing this availablity by minimum of 50kbAny support any support will be appreciated. Thanks,Nitin
