Hi, I am working with F413 and I am using USART3 to receive and trasmit data over UART. As I need to receive unknow size of data I wrote my own interrupt handler for RX. However I would like to transmit data out with a help of DMA. If I call regular poll UART_Transmit(...) function, device will send out data and response from the target will be picked up by RX IRQ handler to a buffer without a problem. I wan't to get rid of blocking UART_Transmit() function. For that reason I configure and setup DMA so I could use non-blocking UART_Transmit_DMA(...) function.With logic analyzer I can see properly formed outgoing and incoming traffic. I would say that DMA transmit works fine... but now I have problem with RX IRQ handler...  My receive IRQ handler looks like this: /* USART3 RX handler */ UART_RX_INTERRUPT_HANDLER_DECLARATION(USART3) { /* Check if receive register is not empty status */ if __HAL_UART_GET_FLAG(&UARTS_Instance()->consts[UART_INSTANCE_3].huart,

Hi everyone!By default, the linker file describes that the memory partitions are configured as:RETRAM - ISR Vector;SRAM1 - Code;SRAM2 - Data;SRAM3 - buffer IPC;SRAM4 - not used in .ld file, but in device tree it's DMA1/DMA2 buffer.My application does not need DMA buffers and I want to use this memory efficiently, namely:RETRAM - ISR Vector;SRAM1+SRAM2 - Code;SRAM3 - Data;SRAM4 - buffer IPC;To do this, I change the linker file accordingly:/** ****************************************************************************** * @file LinkerScript.ld * @author Auto-generated by STM32CubeIDE * Abstract : Linker script for STM32MP157A-DK1 Board embedding STM32MP157AACx Device from STM32MP1 series * 128Kbytes FLASH * 128Kbytes RAM1 * 128Kbytes RAM2 * * Set heap size, stack size and stack location according * to application requirements. * * Set memory bank area and size if external memory is used ****************************************************************************** * @atten

To validate the drive L6474PD I was reading the status through getStatus command but the drive is responding with FFFF. I am not understanding to validate the drive through SPI.

I am currently writing a code to send joystick data from a PC to an STM32 Nucleo board. I use pygame to read joystick values and use the socket library of python to send data to MCU via a router. Both MCU and PC is connected to the router. On the MCU side, I use a modified example code of LWIP given in STM32 Cube pkg. The MCU also runs a FreeRTOS scheduler on which LWIP is running. I was able to get it run flawlessly in a 2 threaded FreeRTOS code. However, when I shift the code to a 16 threaded code[main project], LWIP stops working after a few exchanges. In a sense, I don't receive any ping after 4-5 exchanges.Some things that were experimented with to resolve the issuereduced the publishing frequency from the PC side to 20hz. This increases the exchange duration but fails after few minutes.Tried reducing the ConfigMaxPriority parameter of FreeRTOS config from 56(cube ide default) to 16.[Operating time increased]tried changing FreeRTOS main heap memory and LWIP thread stack memory [no

As the title says. I can see no support for this but a perpiheral advertising with ADV_IND should support this by default.Does anyone know?Regards,AC

I created a simple GPIO program with the code generated from StmCubeMX. When i build the program there are no errors and warnings, but when i connect my Nucleo-F411RE and try to debug it, i get this message in Expressions.The program is supposed to make LED2 go off when i press the Blue button (LED2 is on by default by this code) and it works, i see LED2 turn off when i press the button, and goes back on when i release it, but in Expressions i don't see this. When i press Resume the value should be 1 and when i press the button to go to 0. Instead i get the error.

Hello,​I need use ANA0 and ANA1 as ADC because HW engineer connect ADC signal to those pins. But I don't konw how to config the devicetree. I think ANA0 and ANA1 pin are special pins. Please help me, Thank you.​Shaw.

Hi,(1) Is it ok to install the IDE as my user and not via sudo? It seemed to be ok until I had some later issues which I wont go into here just yet as almost certainly "user error".(2) I installed the ide (as user), and because it was saying it couldn't download firmware, I decided to remove it (rm) and reinstall. It says "nothing to install" despite the --target directory AND the previous workspace being non-existent.So from (2) how is it determining there is "nothing to install" when I have nothing installed?I'm very new to this IDE so please be patient ;)

Hi, I am trying to build the user mode linux driver on my raspberry pi 4 for the VL53L5CX module, and when I follow the instructions in the guide for RPI, I cd into user/test and make, I get the following error:../uld-driver/src/vl53l5cx_api.c: In function ‘_vl53l5cx_send_offset_data’: ../uld-driver/src/vl53l5cx_api.c:163:8: error: ‘memcpy’ accessing 484 bytes at offsets 1288 and 1296 overlaps 476 bytes at offset 1296 [-Werror=restrict] (void)memcpy(p_dev->temp_buffer, &(p_dev->temp_buffer[8]), ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ VL53L5CX_OFFSET_BUFFER_SIZE - (uint16_t)4); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make: *** [Makefile:29: all] Error 1I'm not sure why this is failing, I haven't modified the code in any way.

Hi, I have followed the instructions in the PDF "VL53L5CX_Linux_Getting_started_with_Rpi.pdf" from the VL53L5CX linux driver, and I have built the program. I am having an issue now seeing the TOF sensor when I connect the VL53L5CX-SATEL board to the Rpi in the described way. and, avdd, iovdd, scl, sda are all connected, but when I run i2cdetect on Rpi I get the following:pi@raspberrypi:~/VL53L5CX_Linux_driver_1.1.0/user/test $ i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30: 30 31 32 33 34 35 36 37 38 39 3a 3b 3c 3d 3e 3f 40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 60: 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f 70: 70 71 72 73 74 75 76 77 Every i2c address is showing up, instead of just one for the VL53L5CX.

The sample code from the library worked out of the box. I tried to generate similar code via CubeMX.I tried to set the parameter "radio_bord_if -> Select radio Driver"myself, because without this, the CubeMX issues a warning.However, when building the project, I get incomprehensible errors regardless of the value of this parameter. I didn't find the radio_fw.c anywhere other than the AN5687 description, so I deleted it from the project.After that I got an error: " Error[Pe136]: struct "LmHandlerCallbacks_s" (declared Hat line 135 of "...Repository/STM32Cube_FW_WL_V1.0.0/Middlewares/Third_Party/LoRaWAN/LmHandler\LmHandler.h"h) has no field "GetUniqueId" ...\Project_WL\LoRaWAN_End_Node\LoRaWAN\App\lora_app.c 134 " that I don't understand either.

I just installed FUS 1.2 and BLE Stack Full firmware, I believe successfully based on the logs. I noticed that those sections of memory are not readable by CubeProgrammer. Are they encrypted once they're installed? Just kind of curious.ST-LINK/SWD connection, Nucleo-WB55RG

Hello all,we have a system up and running using TouchGFX. The user interface can be switched between german and english using a system menu of my user interface while running the application on the board.Now we will show the system on an exhibition in Shanghai and would like to have chinese as an additional language. I succeeded to create another language in TouchGFX Designer (vV. 4.10.0), translated some of the menu items into chinese using google translator (e.g. "System setup" = "系统设置" ) and extended the wild cards of my typographics to have characters 0x20-0xFEFF.In the font source there are several characters beyond 0xFF created in the file, however on the system the text is not visible. It shows "??????" which is the fall back character.I use the Windows Font Calibri in different sizes and in notepad the chinese signs are visible with this font so it should be possible to used it for chinese characters. Did anyone manage to get chinese working using TouchGFX?Any hints are very mu

I have 4 PWM out working fine on Tim3.Channel1,2,3,4But the fifth PWM isn't working Tim15Chan2 (PB15=LQFP64pin36)The pin works fine as GPIO so I know it is wired fine.I even tried it as PWM Tim1.Chan3N and PWM Tim8.Chan3N but neither of those work either.I don't see anything in L476 Errata.Any idea what I'm doing wrong? What is difference between Tim15.2 PWM versus Tim3.2 PWM that would give me trouble?Using latest STM32Cube MX, IDE, and Compiler.Paul

For some context, we are prototyping a mobile device and want to achieve good quality stereo audio so we'll be buying some samples of various low power mobile speakers, but want to be in the right ball park before we iterate on final designs.

Is there any good tutorial on using OPAMP and ADC together, esp. on G4 Nucleo board?

I am new to antenna matching so I decided to use the ST25R Antenna Matching tool V3.1. It seems simple enough, and gave me this output after adding in my antenna parameters (taken right from the datasheet):  However when I simulate this circuit in Qucs, the outputs don't seem like the parameters calculated actually matched the antenna: I was under the impression that the circuit should be matched in a way so that the target frequency is in a valley of the S11 plot and a peak of the S21 plot. If that's true, is there a parameter or value I'm not setting correctly or do I just need to do the rest by hand?

Hi,I am trying to enable flash readback protection (level 1) on a STM32F411VET6 using the following HAL code: FLASH_OBProgramInitTypeDef OptionsBytesStruct = {0}; HAL_FLASHEx_OBGetConfig(&OptionsBytesStruct); if (OptionsBytesStruct.RDPLevel == OB_RDP_LEVEL_0) { OptionsBytesStruct.OptionType = OPTIONBYTE_RDP; OptionsBytesStruct.RDPLevel = OB_RDP_LEVEL_1; HAL_FLASH_OB_Unlock(); if (HAL_FLASHEx_OBProgram(&OptionsBytesStruct) != HAL_OK) { HAL_FLASH_OB_Lock(); } HAL_FLASH_OB_Lock(); }Whenever the code is executed (even after power off -> power on (checked multiple times)) the RDP level is readback as level 0 so it proceeds to set it to level 1. I can then connect my ST Link application to it and still readback the flash to confirm its not working. Can you possibly shed any light on what might be going wrong? I've tried stepping through the HAL calls with the debugger and everything looks ok. I can also confirm that the readback protection will work if done man

I'm trying to create process for development with CubeMX/CubeIDE projects.I'm seeing pathing issues that show up when my project is moved. Which also means when it's cloned to another computer.Simple steps I've done to reproduce this:Created a new project with CubeMX. It generated the code and then imported to CubeIDE.Project works and builds.Now, I move the project to a different directory. (Which also happens when I clone it)The project can no longer find files in the "Drivers" subfolder.If I look at one of the files on the original (working) project I can see how it resolves: Once I've moved the folder it resolves different and completely changes the pathing: In practice will want to push and then clone these projects. However, each attempt ends the same way. The pathing resolves differently than where it was generated.How can I make this work?
