Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I have a webserver running on an STM32F407. I have static pages and one dynamic page that updates every 1 second - it just displays the status of the FreeRTOS tasks. Everything is working except that occasionally (3 - 40 seconds) the dynamic page q...
HelloCan someone from ST please put here to download a Working example of the ABOVE?There is noting that workingThe web server is CMSIS v1and the cube does not work at all for ethernet!Thanks
Good morning,I've been fighting with an L496, trying to get it to jump into the bootloader.I'm using STM32CubeIDE 1.7.0 on a Nucleo-L496ZG.The code is based on a new project for the Nucleo board, hints from AN2606.Just to make sure that I wasn't too...
What's the worst that can happen if I assign an interrupt HIGHER prio than timer tick in FreeRTOS? Can I make the microcontroller or the operating system crash? The execution time of the high prio interrupt will be less than 100 microseconds and I pl...
Hi,I had a question regarding Bruno's excellent series on creating a simple bootloader.In part 3, there is an if statement which checks if something has in fact been loaded into the applications's flash region:// bootloader main.c if( ( *(uint32_t *)...
Hi everyone,I am working on an USB-PD source that is battery powered.To make use of the low power features, I defined _LOW_POWER.When this is defined, I get a problem in connection with eletronically marked cables (EMC). Non-EMC cables work fine.The ...
HiI'm trying to read the output from BARCODE reader (ES4650) using USB-HOST using CDC type.On connecting the USB cable I'm getting SOF interrupts (although I disable the Signal SOF on CUBE). On pointing the barcode reader to a barcode I'm getting som...
Hello together,after a lot of trouble getting the USB HS port working on the STM32H747 on the STM32H747I-DISCO Discovery kit I’m stuck again. I’m using STM Cube IDE 1.7 and the HAL USB CDC lib.I was able to get USB CDC working on the M4 thanks to htt...
The X-NUCLEO-LPM01A PowerShield has a dynamic current range maximum of only 50mA.This is a long way short of the maximum current found in many STM32 applications; eg.STM32WL - max Tx current is 120mA;B-L072Z-LRWAN1 - max Tx current of the radio modul...
