Hi, I'm new to PCB design. I'm planning to build a handmade board for a project that uses the STM32F103C8T6, and I've run into some issues in certain parts of the PCB design. My board only has copper on one side (single-sided). For the HSE 8MHz and LSE 32.768kHz crystal oscillators, the body needs to be placed on the bottom layer, with the pins passing through holes to reach the top layer where they will be soldered. I'm concerned about the soldered area where the solder forms a fillet on the top layer, and whether this fillet, being in line with the OSC traces running toward the MCU, could cause problems. To put it simply: could the solder fillet of the crystal on the top layer cause frequency issues, reduced performance, or make it completely unusable? Since my project is currently in the experimental stage, I haven't built the board yet. The images I've included are just for better understanding and were collected from a few websites. What's your opinion on this?

Could you share the schematic file for checking the pin out for this two programmer - STLINK-V3MINIE, ST-LINK/V2-ISOL 

Hello all,I can't download the STM32CubeIDE even as I am registered. There seems to be somthing broken with the Web page. I have tried several browsers. This is what I get, so there is no download button and the table is garbled:Any help appreciated.Johannes 

Hello,We are designing an EVSE for a North American 120/240-V split-phase supply. The EVSE is connected to L1 and L2, with a nominal voltage of 240 V RMS between them. Neutral is not available at the EVSE.We would like to use the STPM34 to measure the L1-to-L2 voltage and calculate the load power and energy. Current sensing is implemented separately using current transformers and is not shown in the attached schematic.Our proposed voltage-sensing circuit uses the primary differential voltage channel as follows:L1 is connected to VIP1 through three series 560-kΩ resistors. L2 is connected to VIN1 through an identical resistor chain. Each input has a 1-kΩ resistor and filter capacitor connected to the local analog ground, iGND_A. iGND_A is the local ground of the isolated STPM34 metrology domain. It is not connected to neutral or protective earth.The intention is to create a symmetrical differential divider so that the voltage between VIP1 and VIN1 is proportional to the L1-to-L2 voltage

Hi All,Where can I find the pin map xml file for the SPC584B-DISP demo board ?

Can anyone please pint me out to a BSDL file useful for STM32H7A3VIH6Q ? Thank youGabriele

The STM32MP2 supports gstreamer. There is a version of Gstreamer for streaming through the WebRTC protocol.Another library for streaming though the WebRTC protocol would be LibWebRTC.My question is if the STM32MP2 have support for LibWebRTC as well?  Thank you for your reply

Hello Everyone,I have a two arduino boards communicating with each other on a CAN Bus. Arduino is connected to CAN Bus via MCP2515 .Both arduino are communicating correctly with each other.

Hi all,I have a CAN 2.0 network up and running with a F407 and some F103. I added a board with a G0B (fdcan). I couldn't get my hands on a FDCAN-tranceiver. I tried to get it working in classic mode (from repository example) with a CAN2.0 tranceiver. I cannot receive any message.So my question is:Is it even possible to configure the G0B to work with a classic CAN2.0 tranceiver?If yes, what would the FDCAN config look likeThank you in advance!Best regards,Philipp

I've been working on getting the STM32f7-EVAL operational to later on migrate it to STM32F767II. For this we decided to split up functionality into 3 sections, there is a forward facing application that has the main and specific business logic. Currently the main issue is that the CAN bus transmit (polling) is working flawlessly yet the receive (interrupt) seems to be non-functional. RF0R.FMP0 remains at 0x0, while FMPIE0 is set (1). it seems as if CAN_RF0R is disabled for some reason. Even though CAN_RX0_IRQn is enabled.  /* CAN1 interrupt Init */  HAL_NVIC_SetPriority(CAN1_RX0_IRQn, 0, 0);  HAL_NVIC_EnableIRQ(CAN1_RX0_IRQn);also the notification is enabled:HAL_CAN_ActivateNotification(&canDef, CAN_IT_RX_FIFO0_MSG_PENDING); after the NVIC and CAN are initialized.void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan)is the callback that i'm using.I also verified using messages coming into the MCU by scope and logic analyser. There is an additional device attached to the CA

Hello,I apologize for any obvious questions, but I am new to CAN and STM32 programming. I have written a code that successfully sends CAN messages to a CANalyzer for data interpretation, so I believe I have enabled the CAN portion correctly. My next objective is to send a message from a CANalyzer to the MCU and have it turn an LED on when it properly received the message. I am using an evaluation board (STM32H7B3I-EVAL).I attached a copy of my main.c file.What I would like to know is how to enable an RX interrupt handler so that I can receive CAN data.What do I have to add to the main.c to make that happen?

Hello,We are using two ST67W611M1U modules (no on-module antenna; external 2 dBi dipole on MHF4) with an STM32H563ZG host, bare-metal, SPI host interface at 10 MHz (the same behaviour was reproduced at 20 and 40 MHz). AT firmware reports AT version:1.0.0.1 (Sep 4 2025 11:32:47), macsw 1.6.44; we are working from the Web AT Documentation v2.0.106.Topology: one module runs as SoftAP (AT+CWMODE=2, AT+CWSAP="…","…",1,3,4,0, AT+CIPMUX=1, AT+CIPSERVERMAXCONN=3, AT+CIPSERVER=1,5000,"TCP", AT+CIPRECVMODE=1), with two stations attached: a second ST67 module and a Windows PC. Steady-state traffic is about 36 kB/s outbound from the AP to the PC (AT+CIPSEND=<link>,1024, ~40 per second) plus about 10 kB/s inbound from the second module (passive receive, one AT+CIPRECVDATA of ~1 kB per 100 ms).We have collected several hundred boot/join cycles with full host-side logs and would appreciate answers or pointers on the following points.1.

Hello,I would like to know when you plan to align your gnu-tools-for-stm32 with Arm GNU Toolchain (15.3.rel1)?Your toolchain is quite old.Or is there a way to use Arm GNU Toolchain (15.3.rel1) instead?It blocks me from moving from CLion (Arm GNU Toolchain 15.3) to STM32CubeIDE for Visual Studio Code. Best regards,Endriu

Hello,I am working on CAN-FD project and and I am able transmit and receive data. Currently it is continuously sending and receiving the data. But I want to send data only when receiver sends data requests. How can I do that? thanks for help

Hi,I'm struggling to get the CAN working on a project I'm working on with the STM32F446ZET6. With the project below (CastletRestart) i just get a flat line of 3.3V high on the TX line for CAN1, this is being tested in loop back mode, with the TUT_CAN_F446 project the can works (downloaded from a tutorial) in loopback mode, as far as i can see ive replicated everything across but it still isnt working.Its likely to be something silly and i do apologise for this being the case but i cannot see what ive missed having reviewed the code countless times.P.s. i am aware the Tutorial project is targeted at a different micro, but the CAN1 ports are the same.Any advice welcomed, thank you for your timeChris

Hello,I am attempting to communicate between my STM32H7B3I-EVAL and a Vector CANalyzer (VN1630A). I previously reached out to figure out why my CAN messages from the CANalyzer are not being received by the STM32 MCU. There was a belief that it was the filters causing the issue, so I did not initialize the filters and tried to see if any message was being received. There are still no messages being received, but I can send them from the STM32 to the CANalyzer without issue. I would like to find out why my code is not working, but I have some specific questions to try and assist my thought process:If the FDCAN_FilterTypeDef is a defined variable but not initialized, it will not filter, correct?Is the function correct for receiving data from the RXBUFFER?if(HAL_FDCAN_GetRxMessage(&hfdcan1, FDCAN_RX_BUFFER0, &RxHeader, RxData) != HAL_OK){ Error_Handler(); }Setup Picture: #include "main.h"   /** @addtogroup STM32H7xx_HAL_Examples * @{ */   /** @addtogroup T

This is a weird one :) I'm using the STM32F769 device, and I have the LTDC peripheral running at low speed (8MHz PCLK). When I send a CAN message to the unit, the CAN RX interrupt is invoked, and only when the ISR exits,  an LTDC error interrupt is raised, which indicates FIFO underrun. Here is a code snippet below:void conv_u32_to_buf(uint32_t num, uint8_t buf[]){   memcpy(buf, (void*)&num, 4);}void CAN1_RX0_IRQHandler(void){   CAN_TypeDef* can = CAN1;   // If CAN message available in the FIFO   if ((can->RF0R & CAN_RF0R_FMP0) != 0U)   {      uint8_t data[8];      // Get pointer to mailbox      CAN_FIFOMailBox_TypeDef* mailbox = &can->sFIFOMailBox[CAN_FILTER_FIFO0];        // This does not work      uint32_t tmp = mailbox->RDLR;      conv_u32_to_buf(tmp, &data[0]);      tmp = mailbox->RDHR;
