CubeMX version 6.5.0 generates the following line in <project>/LWIP/target/ethernetif.h:static void ethernetif_input(void const * argument);Previous version 6.4.0 generated this:void ethernetif_input(void const * argument);The 'static' storage class specifier causes warnings in any module that includes "ethernetif.h". The function could be declared static, but this would best be done modifying the ethernetif.c file. In this manner, removing the declaration entirely from ethernetif.h would be possible, as it really is completely local to ethernetif.c.In any case, unnecessary warnings are not desirable. Follow-up:Modifying ethernetif_header.ftl (C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\db\templates) fixes the issue.

I am doing my bachelors degree and have a task to get two boards communicating using the CAN bus. I just got the boards and they pretty much said "have at it" without any prior knowledge. By now i know most of the really basic stuff about the CAN bus and SPC5Studio but I don't know where to start and what to read. The boards that I got are aek-mot-3p99081 (with the motor) and spc58ec-disp. I also downloaded all of the necessary stuff for the SPC5Studio such as AutoDevKit, MCTK etc. I underastand that i need two terminating resistors and then connect the boards?I am supposed to load the programs to the board and test them out seperately and then start testing the communication between them using the CAN bus. How can i do it and where to start? And might there be a really bored expert that can help a student out for some weird reason with a call or explanation. Thank you for reading :).

From AN Optimized RF board layout for STM32WL Series no recommandation are given for this frequency band.

I have to implement a lifetime counter with microseconds granularity using a STM32L432KC to control an AFBR-S50 sensor. The timer has to count "forever" and this board only has 1 32bit timer, so this timer is for the seconds, i think is the only way. So this timer could count several years. Problem is i also need microseconds.In the sensor documentation they chain 2 32bits counters, but i need three. one 16 bit for microseconds, one 16 bit for miliseconds and 1 32bits for the seconds. The prescaler for the first one is "SystemCoreClock / 1000000 -1" and the counter period is "1000", the second is chained to this, prescaler is 0 and counter period is also "1000". And the third is chained to the second, prescaler also 0 and counter period 0xffff.The first issue with this is i have done a test waiting for 5 minutes and comparing the result with mi cronograph and it has too much delay. The MCU has counter 36 seconds (in 5 minutes) more than the cronograph. How can be this possible?The sec

Hi,I am working on a ZigBee project for the STM32WB55 which requires to send commands to all neighbours in the network. I saw in zigbee.nwk.h that I can request the entries of NeighborTable. Where can I see the max dimension of this table?I found in zigbee.zdo.h this line:/* NOTE was 64, but end up allocating too much on the stack */ #define ZB_ZDO_NEIGHBOR_LIST_MAX_SZ 4UIs that the size that I'm loonking for? If so, considering its size (too small for what I need), is there a way to overcome this limit (or can I modify it)?

Hi everyone!I'm new here and wasn't sure where to post so I apologize if this is in the wrong area.I've attached a picture of a component I'm in need of, but can't find it anywhere online. Can you please help me identify it?It's on a fog machine that was bought new in 2017/2018.Thanks!

I need a strategy for doing CI/CD for our STM32 projects. Having done a little research, the logical path seems to be using a Docker container, as this approach seems to be widely supported.This could either be using a Docker image with all of STM32CubeIDE installed and doing a command line build, or figuring a way to export the project to a runnable make or cmake solution. The path of least resistance seems to be the STM32CubeIDE route, even though the container will be large.Has anyone out there got this working, and if so, how did you get there? I've tried pulling down a couple images with STM32CubeIDE, but am getting various errors trying actually run a headless build in Docker Desktop (on MacOS). It seems this would be a very useful thing for anyone doing serious work with the STM32CubeIDE!!

Im using a stm32f105RBT6 and i am in need a ton of softpwm pins.My solution (with the help of @Community member​ ) was to run 4 DMA channels triggered by 4 different timers addressing 4 different GPIO ports (in a circular mode).This worked like a charm untill now.Now i cannot use the external XTAL anymore, limiting the main clock down from 72Mhz to 36Mhz, this makes the softPWM of the DMA channel with the least priority to lack behind in frecuency.......  I dont know a lot yet about APB /AHB buses but :The DMA1 should be completelly clogging the buses Links of interest:Moving ISR functions to RAM using chibios in a STM32H743xIMoving the NVIC table to RAM to create a bootoader

I have TIM1 configured in one pulse mode triggered by rising edge on TIM1_CH1 to generate single pulse. Timer works correctly (generate single pulse for each rising edge on input). Datasheet claims that TIF flag is set on trigger event in all modes but gated mode. In gated mode flag is set when timer starts and also when stops. I am running timer in trigger mode but flag is rised when trigger event and also when timer stops. Like in gated mode. Looks like a bug. Has anyone observed this problem as well?

The four wire interface from the ST-LINK V2 has no clock.Where does it say that ST devices do not require a clock for SWD ?Also why is it seemingly impossible to work through a hub ? This makes life very difficult.

For RF access, if the requested read is entirely within a locked area, the document shows that both device variants will give an error: But the document doesn't show the corresponding case for I2C - it only shows the case where part of the requested range is locked:So what happens in the case where the requested read is entirely within a locked area?Is there a specific error returned? Or does the entire read give FFs? Or what? What is the recommended way to detect that a read has failed due to locking?ie, how do we know if its genuine FF data, or just FF due to locking?

Short and simple question: Why am I getting this error? Is there something obviously wrong with the schematic?Tested all possible configurations when trying to connect. Holding boot, holding reset, nothing works. The error code changes to target not found when the supply is removed from the MCU.All the voltages around the MCU on the capacitors are right. All capacitors are near the BGA. VDDPA is 1.5V, all VDD pins are 3.3V. There is one thing which bothers me. The vref+ pin is not connected. The datasheet mentions this Pin to be connected to VDDA or Ground, nothing about a floating state. Is it impossible to flash the device when the vref+ pin is floating? Because this is the only problem i can find at the moment.Note. I have access to an X-Ray and all the pins seem to be connected properly.Thanks in advance.

Hi,When debugging with Cube IDE programs without any TouchGFX graphics load quickly using the debugger typically 20 to 30 seconds. When TouchGFX is used such that the NOR Quad SPI Flash has to load the loading time can easily exceed 3 minutes. With only a singles simple screen it takes ~60 seconds.I assumed that if nothing is changes in the graphics from one debug session to another then there would be no changes required in the external graphics flash and so the loading of this memory is unnecessary after it has been loaded once.I therefore turned off the external loaded in the debugger setup:However when I tried this I got the following error:Error in final launch sequence:   Failed to execute MI command: load G:\\ShorttG2\\ShorttG2\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf   Error message from debugger back end: Load failed Failed to execute MI command: load G:\\ShorttG2\\ShorttG2\\STM32CubeIDE\\Debug\\STM32H7B3I_DISCO.elf   Error message from debugger back end: Lo

Just wondering if ST provides a SPICE library for the TS985 comparator? I haven't used many parts from ST and could help with any advice. My goal would be to simulate the comparator within LTSpice.Thanks,Alan

Is there any code example on how to perform the VBAT/3 measurement. I need to measure my battery level (1.8V-2.7V) which I connect to VBAT pin. VDD and the rest of the micro supply pins are coneccted to a DCDC output which gives 3.3V.

Good morning everyone,I'm facing some trouble compiling a project made by SPC5STUDIO 5.8.1 the project is configured by written makefile and rule.mk file.I tried with the last release (V6) and it's not working after importing the project (I did save after the configuration.xml was updated by the spc5studio ), I have compiling errors make:ex: *** No rule to make target 'LINIF.c', needed by '/obj/LINIF.o'. Stop.I guess there's some procedure to follow in order to upgrade the SPC5 studio configuration.xml file in order to make it work.I would like to try with the previous version of spc5Studio but I couldn't find a way to download it , could someone share a link for that version?Thank you.

Hello,I'd like to erase and load an hex file on a STM32 without use the STM32CubeProgrammer as interface. Is it possible integrate the ST-LINK v2 (SWD interface) functionality in a python/C# script to automatize the erase/flashing and integrate it with the rest of the EOL test.If ST-LINK is not suitable can you suggest a different way to implement my goal ?Regards,Riccardo
