Hello developers,I am currently developing all in one AT Slave firmware for STM32WL, which can handle both lorawan and sigfox AT commands. I have tested both AT Slave example of Sigfox and LoRaWAN one by one and  it's working as expected. When i open the .ioc file of this examples (AT Slave LoRaWAN and Sigfox) in CubeMX,  i can see it doesn't allow to enable the Sigfox/LoRaWAN middleware in LoRaWAN/Sigfox example.  So i would like to know how i can enable both the middleware in same firmware, so that my master device can leverage the use of both technologies (LoRaWAN & Sigfox ) in the same chipset. 

I've prepared a small device firmware for a STM32WB35CEU7Ait's only providing battery service and debug infos on serialI've tested it on a P-NUCLEO-WB55 loaded with stm32wb5x_BLE_Stack_full_fw.bin1.19.02 stack loaded @0x080CE000 and it works wonderfully even if .ioc file is based on STM32WB35CEU7A and not on WB55on debug serial all startup is complete :[app_entry.c][APPE_SysUserEvtRx][362] Wireless Firmware version 1.19.0[app_entry.c][APPE_SysUserEvtRx][363] Wireless Firmware build 2[app_entry.c][APPE_SysUserEvtRx][364] FUS version 1.2.0[app_entry.c][APPE_SysUserEvtRx][366] >>== SHCI_SUB_EVT_CODE_READY[app_entry.c][APPE_SysEvtReadyProcessing][452] >>== WIRELESS_FW_RUNNING[app_entry.c][APPE_SysEvtReadyProcessing][476] >>== DBGMCU_GetRevisionID= 2003[app_entry.c][APPE_SysEvtReadyProcessing][481] >>== DBGMCU_GetDeviceID= 495[app_ble.c][APP_BLE_Init][333] Success: SHCI_C2_BLE_Init command[app_ble.c][Ble_Hci_Gap_Gatt_Init][715] ==>> Start Ble_Hci_Gap_Gatt_

Hello ST Community, I am currently working on a flight computer for a model rocket. It will be used together with a barometric pressure to estimate the altitude. It would be very nice if someone could review my schematic and point out any mistakes.

Hi everyone,we are in the middle of bringing up a custom board using the STM32MP131. Booting from an SD card already works. However, we would like to use the STM32CubeProgrammer to directly connect the board via USB. For this, the OTG USB pins OTG_HS_DP and OTG_HS_DM are wired to a USB-A socket. The socket is then connected to a PC using a USB-A to USB-A cable. In serial boot mode, the LED on BOOTFAILN blinks at 5Hz, but the device does not show up on the computer.I assume that this is a hardware issue since USB boot should work before any software is loaded on the device. USB boot works with the STM32MP135-DK, so it should not be a driver issue either. On our board, OTG_HS_ID (PA10) is left floating. This pin has an internal pull-up, which should signal device mode by default. OTG_HS_VBUS (PI7) is also left floating. On the DK-board it is connected to the LCD, so it should also be optional. Power is supplied seperately via the STPMIC1. The MPU and USB port are wired like this:I am uns

I'm using a STM32H745 and running a bootloader on the CM4. In the bootloader I want to set the boot address of the CM7 using the user option bytes. Is this possible and if so, how should I do this?Kind regards

Hi,after reviewing answers to following posthttps://community.st.com/t5/stm32-mcus-touchgfx-and-gui/how-to-draw-pixel-line-or-rectangle/td-p/105737and as a TouchGFX newby, I'm wondering: how one expects to do a following task by using TouchGFX's:there are two images and some fading effect needs to be done: pseudo-random pixels from one hidden in-memory image A being moved to corresponding pixels of currently displayed image B, replacing them one by one, eventually making all pixels of image A equal to pixels of image B.Does it need to be addressed in TouchFGX by creating single-pixel "Line" widget objects for each pixel? Seems like extremely inefficient... Are there any other options to do so?Thanks 

Starting a new STM32F4 project I decided it would be a good idea to update all the development tools.  TouchGFX v 4.23.2STM32CubeMX v 6.11.0STMCubeIDE v 1.15.0 A working .ioc file from the previous project release was upgraded using the latest STM32CubeMX. A couple of modes to main.c required to run the application and a compile was attempted.  The following errors are generated:../TouchGFX/target/generated/STM32DMA.cpp: In function 'void touchgfx::paint::argb8888::lineFromL8ARGB8888(uint8_t*, const uint8_t*, int16_t, uint8_t)':../TouchGFX/target/generated/STM32DMA.cpp:760:9: error: 'L8ClutLoaded' was not declared in this scope760 | if (L8ClutLoaded == 0)| ^~~~~~~~~~~~ ../TouchGFX/target/generated/STM32DMA.cpp: In function 'void touchgfx::paint::argb8888::lineFromL8RGB888(uint8_t*, const uint8_t*, int16_t, uint8_t)':../TouchGFX/target/generated/STM32DMA.cpp:699:62: error: 'L8CLUT' was not declared in this scope699 | WRITE_REG(DMA2D->FGCMAR, reinterpret_

Hello everyone, I'm currently doing some experiments with CAN communication with the STM32F302RB Nucleo board. The board is connected to a wcmcu-230 CAN transceiver which is connected to a Raspberry pi with a CAN header connected to it. The bus is terminated with a 120Ohm resistor on both sides.I generated the HAL with CubeMX. RX1 interrupt is enabled and the pins are left as default:The bus is running on 125kbits/s and is configured as follows:I followed the instructions from this tutorial:https://www.linkedin.com/pulse/unlocking-power-stm32-can-bus-step-by-step-tutorial-haresh-sondagar-whwcf/I use the following code:CAN_RxHeaderTypeDef rxHeader; //CAN Bus Transmit Header CAN_TxHeaderTypeDef txHeader; //CAN Bus Receive Header uint8_t canRX[8] = {0,0,0,0,0,0,0,0}; //CAN Bus Receive Buffer CAN_FilterTypeDef canfil; //CAN Bus Filter uint32_t canMailbox; //CAN Bus Mail box variable //in main: canfil.FilterBank = 0; canfil.FilterMode = CAN_FILTERMODE_IDMASK; canfil.FilterFIFOAss

Hello,i have a board with 10 L6924D on it, the schematic of each channel is derived from STEVAL-ISA076V1(*). Charging works as planned, CC/CV, correct max voltage and charge current and charge-end-current. Both status pins are connected to LEDs as on the devboard, signaling correctly for charging, completed or error. All channels are sharing the 5V input and one line connecting all shutdown pins. The shutdown-line is pulled down by a N-fet to activate the charging or is pulled high to 5V with 10k.When activating the shutdown, the voltage on all chips is a clear 0V or 5V transition and all 10 channels stop charging as expected.What is not as expected, are the flickering status LEDs. Sometimes all are on, sometimes just one of them, sometimes none, and that random for each of the channels. One or two out of ten randomly fade between the LEDs within seconds and I can measure all voltages between 0V and 5V by multimeter and oscilloscope. There is no difference between battery connected or

Hi,Im currently trying to set up a project where Freertos controls a webserver via lwip.I tried following these tutorials/guides and managed to be able to ping the board but not get it to host the webserver.https://github.com/MayaPosch/FreeRTOS_HTTP_server/tree/masterhttps://community.st.com/t5/stm32-mcus/how-to-create-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308/show-comments/trueBoth of these are not for the STM32F429ZITx board So I copied what I thought I needed.Right now I have it set up like this:for the code:The default task calls http_server_netconn_init that cretes a thread. Then this thread is the same as in this tutorial:https://github.com/MayaPosch/FreeRTOS_HTTP_server/tree/masterI also coppied the exact same files over for the fsdata.Im connected via a static ip and when I type the IP in the browser or any link to a page it refuses the connection. I also used Advanced IP scanner to check If it was hosting something, but there was nothing.Does anyone know

Hello everyone,I want to access the page related to STEVAL-3DP001V1 but it does not exist anymore.The page related to its firmware still exist though.Even if the board is now NRND, access to the schematics and documentation should not be lost !Can this page be brought back online please ? Or can we have at least an archive somewhere ?Best regards.

Hi,I am writing a client/server application for STM32WB55. Server behavior is ok. On client side, I connect to a peripheral and try to send 32 bytes packets every 100 ms on peripheral's RX characteristic using aci_gatt_write_without_response function. MTU is set to 156. Nevertheless most of the time the function return with error code 0x64 (insufficient resource). The application is connected to 1 peripheral only, no advertising. I didn't find any helpful information.Any idea? Any orientation for investigation?Thanks, Jacques

Hello, I tried to use openOCD with my custom board based on SPC58EG80E5. I can successfully flash the ELF file of my project with SPC5LNKA debugger, but the debug features such as the watch window and breakpoints do not work. How can I enable these features?

Currently I am using FOC control on a PMSM.How do I apply a holding torque to a motor so that I can lock the rotor.   Thanks

Hello,On nxp website (https://www.nxp.com/webapp/etpu/), i saw than they have developed some function for the eTPU co-processor. But i don't know which "eTPU-equipped device " should i select to program the SPC56 and how to program it .Thank you

Hello.I have developed a module that has an STM32F103ZE controller. This controller has a USB interface.In order to test the modules, this USB interface is to be connected to a Windows PC via a needle bed. Then various test commands are to be sent via the USB interface for testing.However, Windows assigns a new Virtual-ComPort number each time a new module is connected.Is there a way to suppress this so that the same Virtual ComPort number is always assigned?This must only be the case for the test system. Could this be done by adapting the Windows driver? GreetingsRasmus

 From the user manual "A Guide for Using the Artificial Intelligence Enabler VL53L7CH and VL53L8CH Multizone Time-of-Flight (ToF) Sensors" -- specifically the "Histogram Configuration" section -- it mentions that we can use 'start_bin', 'num_bins', and 'sub_sample' to configure the CNH data. I've implemented this configuration using the Example_12_cnh_data.c file, and it works well.My first question is, how many bins are there in the device's raw histogram bins?My second question is, how can I get all raw histogram bins?     Currently, I find that in 4x4 mode, I can obtain a maximum of 75 bins, and in 8x8 mode, a maximum of 18 bins. Is it possible to access all raw histogram bins by editing the API's source code? In other words, assuming the device's raw histogram bins number is 100, how can I obtain 4x4x100 CNH in 4x4 mode, and how to get 8x8x100 CNH in 8x8 mode?Thanks- Jian

Hello I'm developing a self-powered device with "fast charge" feature, which assumes that USB VBUS pin can supply up to 20V. In this case, a simple voltage divider will not be able to provide an acceptable logic level within the range of 5–20 V. Additional voltage comparators, suppressors are not an option as I want to keep things simple. What if calculate a simple resistor divider for 20V, pass the lowered voltage to ADC, measure it and set the state of a VBUS sensing pin programmatically?

We are working with the STM32H745I-DISCO and a custom daughter board we designed that interfaces with the Arduino Style Connectors on the DISCO Board.  We believe that there are errors on both the Altium Source Schematics and the UM2488 (Page 16) for the labels and documentation of CN6 Pins 1 and 2.  I am attaching copies of a page from both sources showing the original labels and our redline corrections.  We traced these signals on the PCB route to verify our corrections are accurate.  ST should really correct this as we spent a good deal of time incorrectly assuming the documentation for these signals was accurate!  This will help save others from going down the wrong path!
